Cummins Insite and Cat ET

Have you actually used it on off-road eq or tried? I'm seriously wondering if a person couldn't connect but just get limited data on off-road applications. Not really concerned with Bluetooth.

Plugs are different. I can connect to Cummins powered equipment with a bench harness but Caterpillar off-road uses a different datalink not J1939/J1708
 
The center pin is the only physical difference right? The cat center pin doesn't have a slot for a key on Cat if I remember correctly.

The thing that baffles me is that the link you posted shows an RP1210a adaptor that comes with software from the way it sounds. I've never seen that before

Which link are you referring to?

It intrigues me for sure. It could be poor wording for stating which software it supports, but it doesn't appear that way.

No, on a Cat the reason the center pin has a key is because if it didn't you could plug the "on highway" adapter into the off-road deuich plug which would be bad since the 12v pins are in different places. All the holes on the off-road 9 pin plug are the same size, the key keeps the on road plug from going in. You can't plug the off road 9 pin into a "on road" plug because 2 holes are smaller. That pic is the truck 9 pin, the 2 holes on the bottom are smaller and keeps the "off road" plug from connecting.

I'm going to call the aforementioned store tomorrow and see what I can find out.

The only thing I haven't gotten to work with a CA3 is a Mercedes on 3dl. I don't know why. We have to use a nexiq
 
If the only difference for on-road vs off-road equipment is the plug then make an adapter harness. Call terminal supply co. Buy a male Deutsch plug that fits the off-road plugs and wire it to an on-road style deutsch plug to adapt to nexiq. That is if that is the ONLY real difference. On some of the older New Holland equipment there were pins in different places and we had what Dearborn called a dog bone. It essentially just plugged inline and moved the pins to the correct location for the modern software and protocol adapter the service tool upgraded to.

That's sort of what I was getting at... The pin out is different but ultimately the same connections should exist, just populating different terminals.

Part number for off Highway to on Highway through cat.

I think you all had it with the tab and socket diameters
 
So is software different or what? Should be a power, ground, and two comm wires to communicate with the engine. The engine and the chassis are on two separate can-bus systems entirely. If you can plug directly into the ECM and communicate with a benchtop harness then you are able to plug into the diagnostic port and communicate given the correct pinout. Maybe there is something I am overlooking other than software issues or maybe it is just "buggy" for lack of a better term.

No, the off-road equipment runs on the CDL (Cat Data Link) not j1708/j1939. The Cat adapter will operate on both which is why the offer both plugs. The software is the same for both.
