Basis of Presentation of Unaudited Interim Condensed Consolidated Financial Statements and Significant Accounting Policies |

| Accounting Policies [Abstract] | |
| BASIS OF PRESENTATION OF UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS AND SIGNIFICANTACCOUNTING POLICIES | BASIS OF PRESENTATION OF UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS AND SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The interim unaudited condensed consolidated financial statements included in this Form 10-Q have been prepared by Digi International Inc. (the “Company,” “Digi,” “we,” “our,” or “us”) pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures, normally included in consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes thereto, including (but not limited to) the summary of significant accounting policies, presented in our Annual Report on Form 10-K for the year ended September 30, 2017, as filed with the SEC (“2017 Financial Statements”). The condensed consolidated financial statements presented herein reflect, in the opinion of management, all adjustments which consist only of normal, recurring adjustments necessary for a fair presentation of the condensed consolidated balance sheets and condensed consolidated statements of operations, comprehensive income and cash flows for the periods presented. The condensed consolidated results of operations for any interim period are not necessarily indicative of results for the full year. The year-end condensed consolidated balance sheet data were derived from our 2017 Financial Statements, but do not include all disclosures required by U.S. GAAP. Recently Issued Accounting Pronouncements Not Yet Adopted In May 2017, FASB issued ASU 2017-09, "Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting." ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The amendments in this update should be applied prospectively to an award modified on or after the adoption date. This ASU is effective for annual periods and interim periods within those annual periods beginning after December 15, 2017, which for us is the first quarter ending December 31, 2018. Early adoption is permitted. We do not expect the adoption of this guidance to have a material impact to our consolidated financial statements. In January 2017, FASB issued ASU 2017-04, "Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." ASU 2017-04 eliminates the second step in the goodwill impairment test which requires an entity to determine the implied fair value of the reporting unit’s goodwill. Instead, an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying value and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The standard, which should be applied prospectively, is effective for fiscal years beginning after December 15, 2019, which for us is our fiscal year ending September 30, 2021. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2017-04 on our consolidated financial statements. In August 2016, FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments." The amendments in this update provide guidance on eight specific cash flow issues, thereby reducing the diversity in practice in how certain transaction are classified in the statement of cash flows. This ASU is effective for annual periods and interim periods for those annual periods beginning after December 15, 2017, which for us is the first quarter ending December 31, 2018. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2016-15 on our consolidated financial statements. In June 2016, FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments." The amendments in this update replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses. This update is intended to provide financial statement users with more decision-useful information about the expected credit losses. This ASU is effective for annual periods and interim periods for those annual periods beginning after December 15, 2019, which for us is the first quarter ending December 31, 2020. Entities may early adopt beginning after December 15, 2018. We are currently evaluating the impact of the adoption of ASU 2016-13 on our consolidated financial statements. 1. BASIS OF PRESENTATION OF UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) In February 2016, FASB issued ASU 2016-02, "Leases (Topic 842)", which amends the existing guidance to require lessees to recognize lease assets and lease liabilities from operating leases on the balance sheet. This ASU is effective using the modified retrospective approach for annual periods and interim periods within those annual periods beginning after December 15, 2018, which for us is the first fiscal quarter ending December 31, 2019. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2016-02 on our consolidated financial statements. In January 2016, FASB issued ASU 2016-01, "Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities." ASU 2016-01 will require equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) to be measured at fair value with changes in fair value recognized in net income. The amendments in this update will also simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, eliminate the requirement for public business entities to disclose the method and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet and require these entities to use the exit price notion when measuring fair value of financial instruments for disclosure purposes. This ASU would also change the presentation and disclosure requirements for financial instruments. In addition, this ASU clarifies the guidance related to valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, which for us is the first fiscal quarter ending December 31, 2018. Early adoption is permitted for financial statements of fiscal years and interim periods that have not been issued. We are currently evaluating the impact of the adoption of ASU 2016-01. In May 2014, FASB issued ASU 2014-09, "Revenue from Contracts with Customers." This guidance provides a five-step analysis in determining when and how revenue is recognized so that an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods and services. It also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, FASB issued ASU 2015-14 "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date" which approved a one-year deferral of the effective date of ASU 2014-09. As a result of this deferral, ASU 2014-09 is effective for our fiscal year ending September 30, 2019, including interim periods within that reporting period. In addition, FASB issued ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2017-14, to provide interpretive clarifications on the new guidance in ASC Topic 606. We are currently working through an adoption plan and have identified our revenue streams and completed a preliminary analysis of how we currently account for revenue transactions compared to the revenue accounting required under the new standard. We intend to complete our adoption plan during the fourth quarter of fiscal 2018. This plan includes a review of transactions supporting each revenue stream to determine the impact of accounting treatment under ASC 606, evaluation of the method of adoption, and completing a rollout plan for implementation of the new standard with affected functions in our organization. Because of the nature of the work that remains, at this time we are unable to reasonably estimate the impact of adoption on our consolidated financial statements. We plan to adopt the new guidance beginning with our fiscal quarter ending December 31, 2018. |

| ACQUISITIONS | ACQUISITIONS Acquisition of Accelerated Concepts, Inc. On January 22, 2018, we purchased all the outstanding stock of Accelerated Concepts, Inc. (“Accelerated”), a Tampa-based provider of secure, enterprise-grade, cellular (LTE) networking equipment for primary and backup connectivity applications. This acquisition is included with our IoT Products and Services segment. The terms of the acquisition include an upfront cash payment together with future earn-out payments. Cash of $16.8 million (excluding cash acquired of $0.3 million) was paid at the time of closing. The earn-out payments are scheduled to be paid in two installments and the payment amount, if any, will be calculated based on the revenue performance of Accelerated products. The first installment will be based on revenues from January 22, 2018 through January 21, 2019 (the “2018 period”) and the second installment will be based on revenues from January 22, 2019 through January 21 2020 (the “2019 period”). The cumulative amount of these earn-outs will be $4.5 million, if certain revenue thresholds are met. Additional payments, not to exceed $2.0 million for both installments, may also be due depending on revenue performance. The fair value of this contingent consideration was $2.3 million at the date of acquisition and at March 31, 2018 (see Note 7 to the Condensed Consolidated Financial Statements). We have determined that the earn-out will be considered as part of the purchase price consideration as there are no continuing employment requirements associated with the earn-out. 2. ACQUISITIONS (CONTINUED) The purchase price was allocated to the estimated fair value of assets and liabilities assumed. The purchase price allocation resulted in the recognition of $6.1 million of goodwill. We believe this is a complementary acquisition for us as it significantly enhances our existing cellular product lines and immediately extends our market reach with a line of commercial routers and network appliance products. This acquisition will further enhance and expand the capabilities of the IoT Products and Services segment (see Note 9 to our Condensed Consolidated Financial Statements). The Accelerated acquisition has been accounted for using the acquisition method of accounting which requires, among other things, that assets acquired and liabilities assumed pursuant to the purchase agreement be recognized at fair value as of the acquisition date. The following table summarizes the preliminary values of Accelerated assets acquired and liabilities assumed as of the acquisition date (in thousands):
Operating results for Accelerated after January 22, 2018 are included in our Condensed Consolidated Statements of Operations. The Condensed Consolidated Balance Sheet as of March 31, 2018 reflects the preliminary allocation of the purchase price to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The net working capital values are preliminary and we expect to finalize them in the fourth quarter of fiscal 2018. The weighted average useful life for all the identifiable intangibles listed above is 5.5 years. For purposes of determining fair value, the purchased and core technology identified above is assumed to have a useful life of five years, the customer relationships are assumed to have useful lives of seven years, the trade name and trademarks are assumed to have useful lives of five years and the order backlog is assumed to have a useful life of one year. Useful lives for identifiable intangible assets are estimated at the time of acquisition based on the periods of time from which we expect to derive benefits from the identifiable intangible assets. The amounts of revenue and net income included in the Condensed Consolidated Statements of Operations from the acquisition date of January 22, 2018 were $6.2 million and $1.4 million, respectively. Costs directly related to the acquisition of $0.3 million incurred in the first six months of fiscal 2018 have been charged directly to operations and are included in general and administrative expense in our Condensed Consolidated Statements of Operations. These acquisition costs include legal, accounting and valuation fees. Acquisition of TempAlert LLC On October 20, 2017, we purchased all the outstanding interests of TempAlert LLC (“TempAlert”), a Boston-based provider of automated, real-time temperature monitoring and task management solutions. The purchase price was $45.0 million in cash adjusted for certain net working capital adjustments. We believe this is a complementary acquisition for us as the acquired technology will continue to be supported to further enhance and expand the capabilities of the IoT Solutions segment (see Note 9 to our Condensed Consolidated Financial Statements). The terms of the acquisition included an upfront cash payment together with future earn-out payments. Cash of $40.7 million (excluding cash acquired of $0.6 million) was paid at the time of closing. The earn-out payments are scheduled to be paid after December 31, 2018 and December 31, 2019 which is the end of the earn-out periods. The cumulative amount of these earn- 2. ACQUISITIONS (CONTINUED) outs for the periods ended December 31, 2018 and 2019, will not exceed $35.0 million and $45.0 million, respectively. The fair value of this contingent consideration was zero at the date of acquisition and at March 31, 2018 (see Note 7 to the Condensed Consolidated Financial Statements). The purchase price was allocated to the estimated fair value of assets acquired and liabilities assumed. The purchase price allocation resulted in the recognition of $17.6 million of goodwill. For tax purposes, this acquisition is treated as an asset acquisition, therefore the goodwill is deductible. We believe that the acquisition resulted in the recognition of goodwill because this is a complementary acquisition for us and will provide a source of recurring revenue in a new vertically focused solutions business. The TempAlert acquisition has been accounted for using the acquisition method of accounting which requires, among other things, that assets acquired and liabilities assumed pursuant to the purchase agreement be recognized at fair value as of the acquisition date. The following table summarizes the preliminary values of TempAlert assets acquired and liabilities assumed as of the acquisition date (in thousands):
Operating results for TempAlert after October 20, 2017 are included in our Condensed Consolidated Statements of Operations. The Condensed Consolidated Balance Sheet as of March 31, 2018 reflects the preliminary allocation of the purchase price to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The net working capital values are preliminary and we expect to finalize them in the fourth fiscal quarter of 2018. The weighted average useful life for all the identifiable intangibles listed above is 6.5 years. For purposes of determining fair value, the purchased and core technology identified above is assumed to have a useful life of five years, the customer relationships are assumed to have useful lives of seven years and the trade name and trademarks are assumed to have useful lives of five years. Useful lives for identifiable intangible assets are estimated at the time of acquisition based on the periods of time from which we expect to derive benefits from the identifiable intangible assets. The amounts of revenue and net loss included in the Condensed Consolidated Statements of Operations from the acquisition date of October 20, 2017 were $5.7 million and $3.1 million, respectively. Costs directly related to the acquisition of $1.4 million incurred in the first six months of fiscal 2018 and $0.4 million incurred in fiscal 2017 have been charged directly to operations and are included in general and administrative expense in our Condensed Consolidated Statements of Operations. These acquisition costs include legal, accounting, valuation and success fees. Pro Forma Financial Information The following consolidated pro forma information is as if these acquisitions had occurred on October 1, 2016 (in thousands):
2. ACQUISITIONS (CONTINUED) Pro forma net loss was adjusted to exclude interest expense related to debt that was paid off prior to acquisition, interest income related to promissory note that was settled prior to acquisition, adjust amortization to the fair value of the intangibles acquired and remove any costs associated with the sale transaction. |

| Earnings Per Share [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| EARNINGS PER SHARE | EARNINGS PER SHARE Basic net (loss) income per common share is calculated based on the weighted average number of common shares outstanding during the period. Diluted net income per common share is computed by dividing net income by the weighted average number of common shares and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares result from dilutive common stock options and restricted stock units. Diluted net loss per common share is computed by dividing net loss by the weighted average number of common shares. All potentially dilutive common equivalent shares are excluded from the calculations of net loss per diluted share due to their anti-dilutive effect for the three and six month periods ended March 31, 2018. The following table is a reconciliation of the numerators and denominators in the net (loss) income per common share calculations (in thousands, except per common share data):
For the three months ended March 31, 2018 and 2017, there were 1,458,297 and 730,400 potentially dilutive shares, respectively, and for the six months ended March 31, 2018 and 2017, there were 1,988,673 and 1,077,150 potentially dilutive shares, respectively, related to stock options to purchase common shares that were not included in the above computation of diluted earnings per common share. This is because the options’ exercise prices were greater than the average market price of our common shares. In addition, due to the net loss for the three and six month periods ended March 31, 2018, there were 275,522 and 333,801 common stock options and restricted stock units, respectively, that were not included in the above computation of diluted earnings per share. |

| MARKETABLE SECURITIES | MARKETABLE SECURITIES Our marketable securities may consist of certificates of deposit, commercial paper, corporate bonds and government municipal bonds. We analyze our available-for-sale marketable securities for impairment on an ongoing basis. When we perform this analysis, we consider factors such as the length of time and extent to which the securities have been in an unrealized loss position and the trend of any unrealized losses. We also consider whether an unrealized loss is a temporary loss or an other-than-temporary loss based on factors such as: (a) whether we have the intent to sell the security, (b) whether it is more likely than not that we will be required to sell the security before its anticipated recovery, or (c) permanent impairment due to bankruptcy or insolvency. In order to estimate the fair value for each security in our investment portfolio, we obtain quoted market prices and trading activity for each security where available. We obtain relevant information from our investment advisor and, if warranted, also may review the financial solvency of certain security issuers. As of March 31, 2018, 28 of our 29 securities that we held were trading below our amortized cost basis. We determined each decline in value to be temporary based upon the above described factors. We expect to realize the fair value of these securities, plus accrued interest, either at the time of maturity or when the security is sold. All of our current holdings are classified as available-for-sale marketable securities and are recorded at fair value on our consolidated balance sheet with the unrealized gains and losses recorded in accumulated other comprehensive income (loss). All of our current marketable securities will mature in less than one year and our non-current marketable securities will mature in less than two years. Our balance sheet classification of available for sale securities is based on our best estimate of when we expect to liquidate such investments and, presently, is consistent with the stated maturity dates of such investments. However, we are not committed to holding these investments until their maturity and may determine to liquidate some or all of these investments earlier based on our liquidity and other needs. During the six months ended March 31, 2018 and 2017, we received proceeds from our available-for-sale marketable securities of $29.5 million and $57.0 million, respectively. At March 31, 2018 our marketable securities were (in thousands):

| FAIR VALUE MEASUREMENTS | FAIR VALUE MEASUREMENTS Fair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. This standard also establishes a hierarchy for inputs used in measuring fair value. This standard maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our assumptions about the factors market participants would use in valuing the asset or liability based upon the best information available in the circumstances. The categorization of financial assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is broken down into three levels. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable for the asset or liability and their fair values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. Level 3 may also include certain investment securities for which there is limited market activity or a decrease in the observability of market pricing for the investments, such that the determination of fair value requires significant judgment or estimation. Fair value is applied to financial assets such as our marketable securities, which are classified and accounted for as available-for-sale and to financial liabilities for contingent consideration. These items are stated at fair value at each reporting period 7. FAIR VALUE MEASUREMENTS (CONTINUED) using the above guidance. The following tables provide information by level for financial assets and liabilities that are measured at fair value on a recurring basis (in thousands):
Our money market funds, which have been determined to be cash equivalents, are measured at fair value using quoted market prices in active markets for identical assets and are therefore classified as Level 1 assets. We value our Level 2 assets using inputs that are based on market indices of similar assets within an active market. There were no transfers into or out of our Level 2 financial assets during the six months ended March 31, 2018. The use of different assumptions, applying different judgment to matters that inherently are subjective and changes in future market conditions could result in different estimates of fair value of our securities or contingent consideration, currently and in the future. If market conditions deteriorate, we may incur impairment charges for securities in our investment portfolio. We may also incur changes to our contingent consideration liability as discussed below. We are required to make contingent payments for our acquisitions. In connection with the October 2015 acquisition of Bluenica Corporation (“Bluenica”), we are required to make contingent payments over a period of up to four years, subject to achieving specified revenue thresholds for sales of Bluenica products. The fair value of the liability for contingent payments recognized upon acquisition was $10.4 million and was $5.7 million at March 31, 2018. We paid $0.5 million for the period ended September 30, 2016 and zero for the period ended September 30, 2017. In connection with the November 2016 acquisition of FreshTemp, LLC (“FreshTemp”), we are required to make a contingent payment after June 30, 2018, for revenue related to specific customer contracts signed by June 30, 2017. The fair value of the liability recognized upon acquisition was $1.3 million and was $0.3 million at March 31, 2018. For the January 2017 acquisition of SMART Temps LLC (“SMART Temps”), we were required to make a contingent payment after December 31, 2017 based on achieving specified revenue thresholds. Since the revenue threshold was not met, no payment was made. The fair value of the liability for contingent payments recognized upon acquisition of SMART Temps was $10,000 and was zero at March 31, 2018. For the TempAlert acquisition, we are required to make contingent payments for the twelve month periods ending December 31, 2018 and December 31, 2019 based on the total Digi IoT Solutions segment revenue. The fair value of the liability for contingent payments recognized upon acquisition of TempAlert and at March 31, 2018 was zero. 7. FAIR VALUE MEASUREMENTS (CONTINUED) For the Accelerated acquisition, we are required to make contingent payments for the twelve month periods ending January 21, 2019 and January 21, 2020, based upon certain thresholds. The fair values of the liability for contingent payments recognized upon acquisition of Accelerated and at March 31, 2018 was $2.3 million. The fair value of these contingent payments was estimated by discounting to present value the probability-weighted contingent payments expected to be made. Assumptions used in these calculations include the discount rate and various probability factors. This liability is considered to be a Level 3 financial liability that is re-measured each reporting period as a charge or credit to general and administrative expense within the Condensed Consolidated Statements of Operations. The following table presents a reconciliation of the contingent consideration liability measured at fair value on a recurring basis using significant unobservable inputs (Level 3) (in thousands):
The change in fair value of contingent consideration relates to the acquisitions of Bluenica, FreshTemp and SMART Temps and is included in general and administrative expense. The change in fair value of contingent consideration reflects our estimate of the probability of achieving the relevant targets and is discounted based on our estimated discount rate. We have estimated the fair value of the contingent consideration based on the probability of achieving the specified revenue thresholds at 93.5% to 98.5% for Bluenica, between 5% and 100% for FreshTemp, 0% for both SMART Temp and TempAlert, and 34.0% to 53.2% for Accelerated. A significant increase (decrease) in our estimates of achieving the relevant targets could materially increase (decrease) the fair value of the contingent consideration liability. |

Amortization expense was $2.6 million and $0.6 million for the three month periods ended March 31, 2018 and 2017, respectively, and $4.3 million and $0.9 million for the six month periods ended March 31, 2018 and 2017, respectively. Amortization expense is recorded on our consolidated statements of operations within cost of sales and in general and administrative expense. 8. GOODWILL AND OTHER IDENTIFIABLE INTANGIBLE ASSETS, NET (CONTINUED) Estimated amortization expense related to identifiable intangible assets for the remainder of fiscal 2018 and the five succeeding fiscal years is (in thousands):
The changes in the carrying amount of goodwill are (in thousands):
Goodwill is tested for impairment on an annual basis as of June 30, or more frequently if events or circumstances occur which could indicate impairment. The calculation of goodwill impairment requires us to make assumptions about the fair value of our reporting unit(s), which historically has been approximated by using our market capitalization plus a control premium for our reporting unit(s). Control premium assumptions require judgment and actual results may differ from assumed or estimated amounts. As of the third quarter of fiscal 2017, we determined that we have two reportable operating segments, our IoT Solutions segment and our IoT Products & Services segment (see Note 9 to the Condensed Consolidated Financial Statements). As a result, we concluded that the IoT Solutions segment and the IoT Products & Services segment constitute separate reporting units for purposes of the ASC 350-20-35 “Goodwill Measurement of Impairment” assessment and both units were tested individually for impairment. Our test for potential goodwill impairment is a two-step approach. First, we estimate the fair values for each reporting unit by comparing the fair value to the carrying value. If the carrying value of the reporting unit exceeds its estimated fair value, then we conduct the second step, which requires us to measure the amount of the impairment loss. The impairment loss, if any, is calculated by comparing the implied fair value of the goodwill to its carrying amount. To calculate the implied fair value of goodwill, the fair value of the reporting unit’s assets and liabilities, excluding goodwill, is estimated. The excess of the fair value of the reporting unit over the amount assigned to its assets and liabilities, excluding goodwill, is the implied fair value of the reporting unit’s goodwill. At June 30, 2017, we had a total of $98.6 million of goodwill on our Condensed Consolidated Balance Sheet for the IoT Products & Services reporting unit and the implied fair value of this reporting unit exceeded its carrying value by approximately 7%. At June 30, 2017, we had a total of $32.5 million of goodwill on our Condensed Consolidated Balance Sheet for the Solutions reporting unit and the implied fair value of this reporting unit exceeded its carrying value by approximately 8%. Based on that data, we concluded that no impairment was indicated for either reporting unit and we were not required to complete the second step of the goodwill impairment analysis. No goodwill impairment charges were recorded. During the second quarter of fiscal 2018, we assessed various qualitative factors to determine whether or not an additional goodwill impairment assessment was required as of March 31, 2018, and we concluded that no additional impairment assessment was required. Should the facts and circumstances surrounding our assumptions change, the first step of our goodwill impairment analysis may fail. Assumptions and estimates to determine fair values are complex and often subjective. They can be affected by a variety of factors, including external factors such as industry and economic trends, and internal factors such as changes in our business strategy and our internal forecasts. For example, if our future operating results do not meet current forecasts or if we 8. GOODWILL AND OTHER IDENTIFIABLE INTANGIBLE ASSETS, NET (CONTINUED) experience a sustained decline in our market capitalization that is determined to be indicated of a reduction in fair value of one or more of our reporting units, we may be required to record future impairment charges for goodwill. An impairment could have a material effect on our consolidated balance sheet and results of operations. We have had no goodwill impairment losses since the adoption of Accounting Standards Codification (ASC) 350, Intangibles-Goodwill and Others, in fiscal 2003. |

| Income Tax Disclosure [Abstract] | |||||||||||||||||||||||||
| INCOME TAXES | INCOME TAXES Income tax provision was $3.0 million for the six months ended March 31, 2018. Net tax expense discretely related to the six months ended March 31, 2018 was $3.0 million, primarily as a result of new U.S. tax legislation that was enacted during the first quarter of fiscal 2018 and the adoption of ASU 2016-09 related to the accounting for the tax effects of stock compensation. The Tax Cuts and Jobs Act of 2017 (the “Act”) was enacted on December 22, 2017. The Act lowered the U.S. federal corporate tax rate from 35% to 21% as of January 1, 2018 and requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred. Due to our fiscal year end, our statutory rate for fiscal 2018 will be a blend of the new and old tax rates. At March 31, 2018 we had not fully completed our accounting for the tax effects of enactment of the Act; however in certain cases, as described below, we have made a reasonable estimate of the effects on our existing deferred tax balances and the one-time transition tax. For the items for which we were able to determine a reasonable estimate, we recognized a provisional income tax expense amount of $2.7 million which is included as a component of income tax expense. We remeasured U.S. deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which requires estimates of our changes in deferred tax assets and liabilities before and after the new statutory rate was enacted. As a result, we are still analyzing certain aspects of the legislation and refining our calculations such as, refining current year estimates and filings of tax returns, of which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. As of March 31, 2018, the provisional amount recorded related to the re-measurement of this deferred tax balance was $2.6 million. In addition, we considered the potential tax expense impacts of the one-time transition tax. The transition tax is based on our total post-1986 earnings and profits (“E&P”) that we previously deferred from U.S. income taxes. We recorded a provisional amount for our one-time transition tax liability for our foreign subsidiaries, resulting in an increase in income tax expense of $0.1 million for the six months ended March 31, 2018. We have not yet completed the calculation of the post-1986 E&P for these foreign subsidiaries and, further, this transition tax is based in part on the amount of those earnings held in cash and other specified assets. This amount may change when we finalize the calculation of post-1986 foreign E&P previously deferred from U.S. federal taxation, evaluate the testing periods for cash and E&P measurement and finalize substantiation of material foreign taxes paid or accrued. Furthermore, it is expected that further guidance will be forthcoming from U.S. Treasury which may or may not impact the final transition tax required. We continue to review the outside basis differential of our foreign investments. At this point, no additional income taxes have been provided for any undistributed foreign earnings not subject to the transition tax and additional outside basis difference inherent in these entities, as these amounts continue to be indefinitely reinvested in foreign operations. Determining the amount of unrecognized deferred tax liability related to any remaining undistributed foreign earnings not subject to the transition tax and additional outside basis difference in these entities (i.e., basis difference in excess of that subject to the one-time transition tax) is not practical at this time, but it is expected that with inclusion of the transition tax, the potential outstanding basis difference as of March 31, 2018 is expected to be a deductible temporary difference for which no deferred tax asset would be allowed. We adopted ASU 2016-09 “Improvements to Employee Share-Based Payment Accounting” on October 1, 2017. As a result of the adoption, we recorded $0.7 million of excess tax expense related to our share-based payments in our provision for income taxes for the six months ended March 31, 2018. Historically, this was record in additional paid-in capital. The excess tax expense related to share-based payments are recognized as tax expense discretely related to the six months ended March 31, 2018. For the six months ended March 31, 2018, our effective tax rate before items discretely related to the period was less than the U.S. statutory rate due primarily to the mix of income between taxing jurisdictions, certain of which have lower statutory tax rates than the U.S., and also due to certain income tax credits generated in the U.S. Income tax provision was $0.9 million for the six months ended March 31, 2017. Net tax benefits discretely related to the six months ended March 31, 2017 were $0.1 million resulting primarily from the reversal of tax reserves due to the expiration of statutes of limitation from U.S. and foreign tax jurisdictions. For the six months ended March 31, 2017, our effective tax rate before items discretely related to the period was less than the U.S. statutory rate primarily due to the mix of income between taxing jurisdictions, certain of which have lower statutory tax rates than the U.S., and certain tax credits in the U.S. Our effective tax rate will vary based on a variety of factors, including overall profitability, the geographical mix of income before taxes and related statutory tax rate in each jurisdiction, and tax items discretely related to the period, such as settlements of audits. We expect that we may record other benefits or expenses in the future that are specific to a particular quarter such as expiration of statutes of limitation, the completion of tax audits, or legislation that is enacted for both U.S. and foreign jurisdictions. 10. INCOME TAXES (CONTINUED) A reconciliation of the beginning and ending amount of unrecognized tax benefits is (in thousands):
The total amount of unrecognized tax benefits that, if recognized, would affect our effective tax rate is $1.1 million, after considering the impact of interest and deferred benefit items. We expect that the total amount of unrecognized tax benefits will decrease by approximately $0.1 million over the next 12 months. |

| PRODUCT WARRANTY OBLIGATION | PRODUCT WARRANTY OBLIGATION In general, we warrant our products to be free from defects in material and workmanship under normal use and service. The warranty periods generally range from one to five years. We typically have the option to either repair or replace products we deem defective with regard to material or workmanship. Estimated warranty costs are accrued in the period that the related revenue is recognized based upon an estimated average per unit repair or replacement cost applied to the estimated number of units under warranty. These estimates are based upon historical warranty incidents and are evaluated on an ongoing basis to ensure the adequacy of the warranty accrual. The following table summarizes the activity associated with the product warranty accrual (in thousands) and is included on our Condensed Consolidated Balance Sheets within current liabilities:

| Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| STOCK-BASED COMPENSATION | STOCK-BASED COMPENSATION Stock-based awards were granted under the 2018 Omnibus Incentive Plan (the “2018 Plan”) beginning January 29, 2018 and, prior to that, were granted under the 2017 Omnibus Incentive Plan (the “2017 Plan”). Upon stockholder approval of the 2018 Plan, we ceased granting awards under any prior plan. Shares subject to awards under prior plans that are forfeited, canceled, returned to the Company for failure to satisfy vesting requirements, settled in cash or otherwise terminated without payment also will be available for grant under the 2018 Plan. The authority to grant options under the 2018 Plan and to set other terms and conditions rests with the Compensation Committee of the Board of Directors. The 2018 Plan authorizes the issuance of up to 1,500,000 common shares in connection with awards of stock options, stock appreciation rights, restricted stock, restricted stock units, performance-based full value awards or other stock-based awards. Eligible participants include our employees, our affiliates, non-employee directors of our Company and any consultant or advisor who is a natural person and provides services to us or our affiliates. Options that have been granted under the 2018 Plan typically vest over a four-year period and will expire if unexercised after seven years from the date of grant. Restricted stock unit awards (“RSUs”) that have been granted to directors typically vest in one year. RSUs that have been granted to executives and employees typically vest in January over a four-year period. Awards may be granted under the 2018 Plan until January 28, 2028. Options under the 2018 Plan can be granted as either incentive stock options (“ISOs”) or non-statutory stock options (“NSOs”). The exercise price of options and the grant date price of restricted stock units shall be determined by our Compensation Committee but shall not be less than the fair market value of our common stock based on the closing price on the date of grant. Upon exercise, we issue new shares of stock. As of March 31, 2018, there were approximately 1,359,416 shares available for future grants under the 2018 Plan. Our equity plans and corresponding forms of award agreements generally have provisions allowing employees to elect to satisfy tax withholding obligations through the delivery of shares, having us retain a portion of shares issuable under the award or paying cash to us for the withholding. During the six months ended March 31, 2018 and 2017, our employees forfeited 68,611 shares and 43,160 shares, respectively in order to satisfy $0.7 million and $0.6 million, respectively of withholding tax obligations related to stock-based compensation, pursuant to terms of awards under our board and shareholder-approved compensation plans for each respective period. Cash received from the exercise of stock options was $3.4 million and $3.2 million during the six months ended March 31, 2018 and 2017, respectively. We sponsor an Employee Stock Purchase Plan (the “Purchase Plan”), covering all domestic employees with at least 90 days of continuous service and who are customarily employed at least 20 hours per week. The Purchase Plan allows eligible participants the right to purchase common stock on a quarterly basis at the lower of 85% of the market price at the beginning or end of each three-month offering period. Employee contributions to the Purchase Plan were $0.6 million and $0.5 million during both six month periods ended March 31, 2018 and 2017. Pursuant to the Purchase Plan, 74,381 and 48,299 common shares were issued to employees during the six months ended March 31, 2018 and 2017, respectively. Shares are issued under the Purchase Plan from treasury stock. As of March 31, 2018, 366,641 common shares were available for future issuances under the Purchase Plan. Stock-based compensation expense is included in the consolidated results of operations as follows (in thousands):
Stock-based compensation cost capitalized as part of inventory was immaterial as of March 31, 2018 and September 30, 2017. 13. STOCK-BASED COMPENSATION (CONTINUED) Stock Options The following table summarizes our stock option activity (in thousands, except per common share amounts):
(1) The aggregate intrinsic value represents the total pre-tax intrinsic value, based on our closing stock price of $10.30 as of March 31, 2018, which would have been received by the option holders had all option holders exercised their options as of that date. The intrinsic value of an option is the amount by which the fair value of the underlying stock exceeds its exercise price. The total intrinsic value of all options exercised during the six months ended March 31, 2018 was $0.5 million and during the six months ended March 31, 2017 was $0.9 million. The table below shows the weighted average fair value, which was determined based upon the fair value of each option on the grant date utilizing the Black-Scholes option-pricing model and the related assumptions:
Expected volatilities are based on the historical volatility of our stock. We use historical data to estimate option exercise and employee termination information within the valuation model. The expected term of options granted is derived from the vesting period and historical information and represents the period of time that options granted are expected to be outstanding. The risk-free rate used is the zero-coupon U.S. Treasury bond rate in effect at the time of the grant whose maturity equals the expected term of the option. As of March 31, 2018 the total unrecognized compensation cost related to non-vested stock options was $5.0 million and the related weighted average period over which it is expected to be recognized is approximately 2.8 years. 13. STOCK-BASED COMPENSATION (CONTINUED) Non-vested Restricted Stock Units A summary of our non-vested restricted stock units as of March 31, 2018 and changes during the six months then ended is presented below (in thousands, except per common share amounts):
As of March 31, 2018, the total unrecognized compensation cost related to non-vested restricted stock units was $6.6 million, and the related weighted average period over which it is expected to be recognized is approximately 1.7 years. |

Q3 2017 Restructuring In May 2017, we approved a restructuring plan primarily impacting our France location. We also eliminated certain employee costs in the U.S. The restructuring is a result of a decision to consolidate our France operations to our Europe, Middle East and Africa (“EMEA”) headquarters in Munich. The total restructuring charges amounted to $2.5 million that included $2.3 million of employee costs and $0.2 million of contract termination costs during the third quarter of fiscal 2017. These actions resulted in an elimination of 10 positions in the U.S. and 8 positions in France. The payments associated with these charges are expected to be completed by the end of the fourth quarter ending September 30, 2018. |

| COMMON STOCK REPURCHASE | COMMON STOCK REPURCHASE On May 2, 2017, our Board of Directors authorized a program to repurchase up to $20.0 million of our common stock primarily to return capital to shareholders. This repurchase authorization expired on May 1, 2018 (see Note 16 to the Condensed Consolidated Financial Statements). Shares repurchased under the program will be made through open market and privately negotiated transactions from time to time and in amounts that management deems appropriate. The amount and timing of share repurchases depends upon market conditions and other corporate considerations. During the third quarter of fiscal 2017, we began to repurchase our common stock on the open market. During the third quarter of fiscal 2017, we repurchased 28,691 shares for $0.3 million. As of March 31, 2018, $19.7 million remained available for repurchase. No further repurchases of common stock were made under this program. |

| Subsequent Events | SUBSEQUENT EVENTS Manufacturing Transition Subsequent to the end of the second quarter of fiscal 2018, as announced on April 3, 2018, Digi will transfer the manufacturing functions of its Eden Prairie, Minnesota operations facility to existing contract manufacture suppliers. As a result, approximately 60 positions are planned to be eliminated over the next 120 days, resulting in restructuring charges amounting to approximately $0.6 million related to employee costs during the third and fourth quarters of fiscal 2018. The payments associated with these charges are expected to be completed by December 31, 2018. This manufacturing transition is expected to result in total annualized savings of approximately $3.0 million to $5.0 million. Stock Repurchase Program Subsequent to end of the second fiscal quarter of 2018, on April 24, 2018 our Board of Directors authorized a new program to repurchase up to $20.0 million of our common stock primarily to return capital to shareholders. This repurchase authorization expires on May 1, 2019. Shares repurchased under the new program will be made through open market and privately negotiated transactions from time to time and in amounts that management deems appropriate.

Basis of Presentation of Unaudited Interim Condensed Consolidated Financial Statements and Significant Accounting Policies (Policies) |
6 Months Ended |

Mar. 31, 2018 | |
| Accounting Policies [Abstract] | |
| Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements Not Yet Adopted In May 2017, FASB issued ASU 2017-09, "Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting." ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The amendments in this update should be applied prospectively to an award modified on or after the adoption date. This ASU is effective for annual periods and interim periods within those annual periods beginning after December 15, 2017, which for us is the first quarter ending December 31, 2018. Early adoption is permitted. We do not expect the adoption of this guidance to have a material impact to our consolidated financial statements. In January 2017, FASB issued ASU 2017-04, "Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." ASU 2017-04 eliminates the second step in the goodwill impairment test which requires an entity to determine the implied fair value of the reporting unit’s goodwill. Instead, an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying value and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The standard, which should be applied prospectively, is effective for fiscal years beginning after December 15, 2019, which for us is our fiscal year ending September 30, 2021. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2017-04 on our consolidated financial statements. In August 2016, FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments." The amendments in this update provide guidance on eight specific cash flow issues, thereby reducing the diversity in practice in how certain transaction are classified in the statement of cash flows. This ASU is effective for annual periods and interim periods for those annual periods beginning after December 15, 2017, which for us is the first quarter ending December 31, 2018. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2016-15 on our consolidated financial statements. In June 2016, FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments." The amendments in this update replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses. This update is intended to provide financial statement users with more decision-useful information about the expected credit losses. This ASU is effective for annual periods and interim periods for those annual periods beginning after December 15, 2019, which for us is the first quarter ending December 31, 2020. Entities may early adopt beginning after December 15, 2018. We are currently evaluating the impact of the adoption of ASU 2016-13 on our consolidated financial statements. 1. BASIS OF PRESENTATION OF UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) In February 2016, FASB issued ASU 2016-02, "Leases (Topic 842)", which amends the existing guidance to require lessees to recognize lease assets and lease liabilities from operating leases on the balance sheet. This ASU is effective using the modified retrospective approach for annual periods and interim periods within those annual periods beginning after December 15, 2018, which for us is the first fiscal quarter ending December 31, 2019. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2016-02 on our consolidated financial statements. In January 2016, FASB issued ASU 2016-01, "Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities." ASU 2016-01 will require equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) to be measured at fair value with changes in fair value recognized in net income. The amendments in this update will also simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, eliminate the requirement for public business entities to disclose the method and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet and require these entities to use the exit price notion when measuring fair value of financial instruments for disclosure purposes. This ASU would also change the presentation and disclosure requirements for financial instruments. In addition, this ASU clarifies the guidance related to valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, which for us is the first fiscal quarter ending December 31, 2018. Early adoption is permitted for financial statements of fiscal years and interim periods that have not been issued. We are currently evaluating the impact of the adoption of ASU 2016-01. In May 2014, FASB issued ASU 2014-09, "Revenue from Contracts with Customers." This guidance provides a five-step analysis in determining when and how revenue is recognized so that an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods and services. It also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, FASB issued ASU 2015-14 "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date" which approved a one-year deferral of the effective date of ASU 2014-09. As a result of this deferral, ASU 2014-09 is effective for our fiscal year ending September 30, 2019, including interim periods within that reporting period. In addition, FASB issued ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2017-14, to provide interpretive clarifications on the new guidance in ASC Topic 606. We are currently working through an adoption plan and have identified our revenue streams and completed a preliminary analysis of how we currently account for revenue transactions compared to the revenue accounting required under the new standard. We intend to complete our adoption plan during the fourth quarter of fiscal 2018. This plan includes a review of transactions supporting each revenue stream to determine the impact of accounting treatment under ASC 606, evaluation of the method of adoption, and completing a rollout plan for implementation of the new standard with affected functions in our organization. Because of the nature of the work that remains, at this time we are unable to reasonably estimate the impact of adoption on our consolidated financial statements. We plan to adopt the new guidance beginning with our fiscal quarter ending December 31, 2018. |
