Caterpillar comm adapter cable diagram

[Khein]

I need CAT comm adapter cable diagrams in order to try continuity and to connect to ECM and machines I dont have the adapter.
I have a similar diagrams from Cummins manuals but I think they are different, so if anyone can share this I will be very happy. This is that I need to know wich pin of the 9-pin cable are for batery energy, wich are for J1939 information, wich are for J1708 information and so. The same hapens with the other cables.
Thanks in advance.

But I dont understand something. Wich is the difference beetwen the data link connection and the J1939 connection? When or wheren you use them?
And if I need to connect using J1708, can I do it with this cable and comm adalter 3???

Its ok, Data link is J1708, the use depends on the equipment but the interface recognizes the one it has. I've barely seen it on caterpillar, they always use CAT data link trough J1939. you do have comm adapter 3 but you dont have the connector? or wich is the problem?

I have all connectors but Im trying to connet to a ECM taken off the engine and I dont know if I have to use J1939 or J1708 because is an old ECM (3116E).
So I needed to know where I have to connect
Any recommendations when doing this?

Your engine is a 3126 not a 3116
What is the engine number?

Hello friend, I am new with the use of nexiq, you would have a detail of each pin of the Nexiq connector, I know that pin 08 is the positive battery and pin 06 negative of the battery, the others I am in doubt, especially the Data Link . Thank you

I need this information to make a cable for reading on a Caterpillar 938H because we do not have the cable here for purchase. Thank you thank you
Olá amigo, sou novo com o uso do nexiq, você teria um detalhe de cada pino do conector Nexiq, sei que o pino 08 é a bateria positiva e o pino 06 negativo da bateria, os outros eu sou em dúvida, especialmente o Data Link. Obrigado
