9 pin cable to establish direct connection to the diagnostic port for CAT trucks with J1939 Data Link communication line. SKU: 144300K245. We provide a Modbus converter for the CAT CCM Module that is a canned solution. My company, Monico, is now selling a CAT Data Link Gateway that. Proprietary PGN's on a J1939 link and does not use the CDL at all.

I have a Cat generator that I want to monitor more extensively so I am just starting to investigate the possibility of using the built in modbus. I had the Cat guy out for a different reason and he pointed out the connection and set it up, now the rest is up to me. The ecmp is v3.2. I have glanced through some threads and see there was some discussion that the registers that will be available are somehow non-standard (if there is such a thing as a standard) and also the option of using the J-1937 (I might have that number wrong) interface which from what I gather is even more exotic. What I am looking for today is a primer on making this work. The Cat tech is coming back next week so if there are any configuration options I need him to set up I will have that opportunity then. I'm looking for advice from those who have done this before and it seems there are a few around here. There are conversion modules available that seem to do all the work taking the modbus right to ethernet in an A/B tag format. Comments on those would be welcome as well. I don't intent to control the Gen or the ATS, all I really want to do is to monitor its status, outputs and health. Thanks for the help.
