Form 10-K for the fiscal year ended September 30, 2023 Form 8-K furnished on January 31, 2024 File No. 001-34033 Dear James Loch: We have reviewed your February 16, 2024 response to our comment letter and have the following comments. Please respond to this letter within ten business days by providing the requested information or advise us as soon as possible when you will respond. If you do not believe a comment applies to your facts and circumstances, please tell us why in your response. After reviewing your response to this letter, we may have additional comments.

Form 10-K for the Fiscal Year Ended September 30, 2023 Notes to Consolidated Financial Statements Note 1. Summary of Significant Accounting Policies Revenue Recogntion, page 44 1. We note your response to prior comment 4 where you indicate contracts with multiple performance obligations that include implementation fees are isolated to SmartSense arrangements in which you do not retain ownership. However, SmartSense appears to be part of your IoT Solutions segment while your proposed revised discussion of multiple performance obligations refers to Digi Remote Manager, which appears to be part of your IoT Product and Services segment. Please explain this apparent inconsistency. In addition, we note from your response to prior comment 5 that customers in your IoT Products and Services segment can purchase services such as Digi Remote Manager, Lighthouse Management software or technical services. Tell us whether you have other multiple James Loch FirstName LastNameJames Loch Digi International Inc.

Please address the following as it relates to your response to prior comment 5: You state that end users purchase the hardware products in your IoT Products and Services segment (P&S segment) based on consideration of the hardware products technical features and functionality. Provide us with a discussion of the features and functionalities separately for the products in each of the operating segments and explain how any differences in features and functionalities factored into your qualitative analysis.

You state all P&S product lines leverage third-party contract manufacturers that typically supply a range of products that cut across the operating segments. Tell us whether each of your operating segments use contract manufacturers for the supply of all products or whether any are manufactured by the company, and if so, to what extent. Tell us more about the mix of contract manufacturers, including whether certain manufacturers are primarily responsible for supplying products to a particular segment, and if so, why. Describe further the manufacturing process performed by these third-parties for each operating segment and how they are similar and whether there are any differences. Also, provide further detail regarding the range of products provided by the contract manufacturers and the specific segments to which they relate. You indicate that distributors and resellers are typically your customer in the P&S segment. Describe any differences between the industries served by the distributor and reseller customers of each operating segment, and how any differences were considered in your analysis. Also describe the types or classes of customers for each segment other than distributors and resellers, and the types of products and services they purchase.
