If you are looking for an inexpensive handheld tool to help you service, maintain, and monitor the performance of your Cummins-powered investments and that integrates the data link adapter function into one rugged, high performance, easy to use package that will not become obsolete fast, you need a Cummins QC5100 handheld computer with an integrated INLINE 4 data link adapter and Windows® CE operating system to read your engine data broadcast over the public SAE J1939 or J1587 data links.

INSITE is a PC-based software application that provides quick and easy access to your engine's electronic performance information, which enables faster service turnaround times.  

Cummins INLINE 4 and INLINE 5 Data Link Adapters are genuine Cummins products and are the only adapters available that Cummins certifies to be 100% compatible with all features of the latest Cummins software applications.
