so i bought a galant a few months back and when i pulled the ecu out to swap chips i found a little addon card inside it with a max202cpe ic on it. its some sort of serial transceiver. theres a rj25 wire coming out of the ecu and the car came with a little adapter to go from that to male db9. i hooked up my palm and tried mmcd and pokedyno and couldnt get anything to communicate.
i also did some searching and cant find anything like this and theres no markings on the little pcb. has anyone seen this before or know how to make it work?

Is that acid I see on the board?

That's something Jeff did for a few people back in the day. I had him do that to my ECU years ago. I think you're supposed to hook it to a pc for data logging via mmcd.

The rj25->db9 adapter that came with the car is the wrong gender to plug into my computers serial port, but it plugs into my palm cable.
I guess I will email Jeff O. about it. I couldnt find it on his site.

Don't Palms and PCs use different adapters? If it was set up to work with a PC, I think you either need the correct adapter/cable for the Palm or get a male to female adapter to link it with a laptop.

i found a null modem adapter in my desk this morning. im going to try that when i get home from work today. i believe its just a matter of swapping pins 2 and 3 based on the device trying to connect.

Yeah null modem adapter, I'm sure that's what you need for it. I couldn't remember the term for it earlier.

Apologies for the thread revival but noticed what looks like one of these serial boards on my 7201 ECU yesterday (I also have a 7202 but didn't see it on that one)

Anyone know / remember which pins were soldered where to connect to the RS-232 header per chance??

Thanks!
