Found one here........
Couldn't find this anywhere by searching. I need to know what pins are being used by the serial port of the brainstem. I'm assuming its only 4 pins, but I just need to know which pins those are.
Actually that still doesn't answer my question - I already know what the DSATX side of the Brainstem pinout is - I need the serial side of it.
HOWEVER, that link you posted has an item that will work for what I need - I needed an extension cable as I can't plug in the Brainstem in the DSATX and have a serial cable plugged into it as well (due to my layout). My idea was I would just extend the serial portion from the Brainstem using whatever wires I needed but this extension cable does exactly what I need so I thank you for that find.
Actually when I look close at that picture on that site (which is the same in the manual) I believe it does tell me the pinout - I guess it's really only two signals from the serial port that are used - RTS and CTS which that points out on the Brainstem.
OK so looking at that 2nd link you posted, I'm guessing I really would have had to wire all 9 pins up.
