Note that INSITE versions earlier than this are not fully RP1210B compliant and may not work with these adapters. See the chart below for an example of the basic connections needed to hook-up to the vehicle data link
You should be at Insite version 7.6.2 to get the best performance out of Insite. Inline 6 just has new features. Here are the changes INLINE 6 Data Link Adapter. This new adapter is now the only genuine or HQ clone Cummins product on the market and is the only adapter available that Cummins certifies to be 100% compatible with all features of the latest Cummins ECMs and software applications. The INLINE 6 can communicate with your PC through a 9-pin serial connector. The INLINE 6 also can communicate with your PC over a Universal Serial Bus (USB) through a 4-pin standard connector. The INLINE 6 adapter connects to vehicle power, the SAE J1708/J1587 data link, and two CAN/J1939 data links via a 25-pin serial connector. With full compliance to the Technology and Maintenance Council’s RP1210 standard, the INLINE 6 will work with the latest Cummins INSITE, PowerSpec, and Calterm III software applications. It will also work with any other software applications that are fully compliant with the RP1210 standard (note that while some non-Cummins applications fully support RP1210, others do not, so you should test each application in question with the INLINE 6 adapter to make that determination
That is fine, working on 2010 and older trucks. The inline 5 will work on all applications as long as Insite version is up to date 7.5 or higher is required. I would go with the Inline 6 because Cummins is in the process of testing an Inline 8 adapter. You will find on some older engines Inline 5 and 6 is too fast and you must drop down to a Inline 4 or below. But the Inline 5 will work for your needs.
