The Nexiq adapter is able to work perfectly with Caterpillar Electronic Technician software.
Nexiq has no problems working with Cat ET. If the Cat is in a GM truck, you will need a special Cat OBDII connector. In trucks with the standard 6/9 pin connector, there is no issues.
Works on BHL F-series , Whl excav. and wheel loaders, but better option is Cat ET
Nexiq adapters work with Cat ET on truck engines.
NOT work on construction equipment due to a different communication protocol. Will need a Cat Comm 3 for those.
Btw, spend the money on a real Nexiq or good china clone if you do….stay away from the cheap china knockoffs. They work, kinda, but for how long and no support.
This is a working china clone Nexiq adapter at a good price
Here are Nexiq USB Link adapter and CAT ET connection issues and solutions, which might help you out.
– Connection Error 434:
The reason for error 434 might be the adapterserver in the Cat software, change it for the chinese Cat server and it will work, at least here it does after the 434 error, C:\Program Files (x86)\Common Files\Offboard Information Products, look here for “”CommunicationAdapterServer.exe”and “CommunicationAdapterServerps.dll” by me dll file was not there but I put it anyway, I copied it from a other XP computer who was working with the chinees cat adapter, however I put it in a WIN 7 computer, that was working too after the change, I m new here have no idea how to share the files, but I have them here, save the original files in a new folder, never know if you ever get a original one (-: , hope that I could help you with this info
– Connection Error 149:
Utilities -> Preferences -> Communications -> RP1210 Compilant Device then Advanced Choose USB Nexiq Link
If it doesn’t work,
Reinstall drivers and verify that you have this in the device manager
JUNGO USB LINK WINDRIVER if you missing one of this it wont work
You need to run this program in compatibility mode for windows xp, sp 3 to get the nexiq to work on windows 7. i was getting the same notice that my nexiq was not a rp1210 compliant device, i went to programs and selected cat (etech), right clicked, properties, compatibility, and chose windows xp sp3. went back to cat, and the device works perfectly now. That will fix this issue
