Palm M125 Logger cable issue

[Rocket]

Hey all! I have a palm m125 running MMCd (1.8 I think). I have a cable that came with it but after it got shuffled around the last couple of years while the car sat, the M125 cable has come apart at the serial cable end. There is a Red, Brown, and Black wire. I will follow with a picture from my phone as a reply. Anyone help me out with what pins to re-solder it?

TIA!

This is a fairly standard color pinout, but I can't say for sure...


Pin 1 - Black
Pin 2 - Brown
Pin 3 - Red
Pin 4 - Orange
Pin 5 - Yellow
Pin 6 - Green
Pin 7 - Blue
Pin 8 - Violet
Pin 9 - Gray

Tks Doc

that may help. I figure if anything that I will check the pins that have solder on them and see if grnd, tx, and rx are soldered. If so black will go to grnd and then test red to tx and brwn to rx. Then switch the 2 rd/brwn.

It may also use the brown as ground, DB9 pinouts are "wrong" sometimes.

IIRC, the black wire goes to pin 12, the brown to 10, & the red to 1.

Edit: If you are talking about an OBD1 diagnostic port connection.

What I have are 2 cables with a serial port in the middle. One cable (the good one) has the OBDI on the other end. The cable that came apart is the one that plugs into the M125 and runs to a serial cable. Pins 2, 3, and 5 have Solder on them. Which are tx, rx, and grnd. Doc you make a good point. I may have to take my ohm meter and test continuity between the wires and the pins that plug into the m125 and see if I can find a pin out for it. That would let me know exactly which goes where. I was hoping someone would have it off the top of their head to make things go faster :) :) :)

Thanks guys!!!
