issues with nexiq connecting to insite

[shawnisx15]

hi yall,

i have a cheap chinese nexiq link 2 bluetooth adapter that im trying to connecting to cummins insite.
the adapter is connecting to the nexiq device tester app and runs well showing connected status
but does not connect to insite
insite says error code 5202, which means your computer cannot talk to your data link adapter
so insite not connecting but does connect to the nexiq device tester app
the power light and and data transfer light is on when running the nexiq device tester .
i will try to install manually or maybe use another driver

does anyone have any knowledge of this or tips on what to do?
thank you in advance

Although the chineesium 'Inline-6' adapters have a decent track record for working well, those chineesium 'nexiq' adapters have never been any good. Your moneys would be far better spent going to a local fleet-pride or napa and buying a legitimate one instead.

which version of insite are you using and what is the year of the vehicle ur working on ?

older versions of insite such as 7.6.2 generally no longer connect to 2020+ trucks...

the version of insite you're using should work perfectly fine...

the datalink adapter you got though, not so much...

The 1st generation nexiq was pretty awful to begin with... the Chinese versions are even more awful, and rarely work or hold a steady/reliable connection in order for insite to communicate properly. worth a shot checking all your protocols, J1708 looks like it works in your photo, make sure J1939 Chan-1 does as well in device tester, and make sure insite is configured to communicate with "USB-Link", not USB-Link 2 or 3, and make sure its set to "auto-detect" instead of J1708/J1939...

if it still wont work, best bet is to either spend the 800 or so dollars on a geniune nexiq if its something you use every day... or if you dont wanna break the bank and only need it every once in a while, get yourself a chinese INLINE 6 off amazon or ebay for $200 and call it a day.
