   1.                                                   You state that the 
increase in IoT Products and Services revenue in fiscal 2023 was
                                                        primarily due to the 
growth in sales volume for both your OEM and Infrastructure product
                                                        lines. In addition, you 
attribute the growth in the IoT Solutions revenue to both your
                                                        SmartSense by Digi and 
Ventus offerings, as well as the Ventus acquisition. Where two or
                                                        more factors contribute 
to a material change in revenue or expenses from period-to
                                                        period, including any 
offsetting factors, please revise to include a quantitative discussion
                                                        of such factors. Also, 
avoid using vague terms such as "primarily" in favor of specific
                                                        quantification. Similar 
revisions should be made to your discussion of operating expenses
                                                        along with a separate 
discussion of any material change in each individual expense line
                                                        item. Refer to Item 
303(b) of Regulation S-K.

3.       You state that that platform-as-a-service (PaaS) revenue and support 
services revenue are
         recognized over the life of the contract term. Please revise to 
clarify when you invoice
         your customers for such services. Also, tell us whether the number of

and if so, what
         impact that has on the amount of revenue recognized each period. 
Lastly, revise to clarify
         the methods used to recognize revenue for services that are 
transferred over time. Refer
         to ASC 606-10-50-18(a).
4.       Please address the following as it relates to your contracts with 
multiple performance
         obligations:
             Explain further what is included in the implementation fee that is 
charged when you
             retain ownership of the equipment and how you determined that 
ratable recognition is
             appropriate.
             Tell us the amount of revenue from multiple performance obligation 
arrangements for
             each period presented as well as from the implementation fees 
included in such
             arrangements.
             Tell us and revise to disclose how you determine the 
stand-alone-selling price for
             each of the performance obligations in your multiple performance 
obligation
             arrangements.

5.       We note that you considered various qualitative and quantitative 
factors in determining

         Please provide us with a detailed analysis of each of the criteria in 
ASC 280-10-50-11 for
         each operating segment to support such aggregation. Also, provide us 
with any underlying
         financial information considered as part of your quantitative 
analysis.
