If it's multiple pins, you best use a PIC/Atmel/whatever controller to convert this to a half duplex RS232 the Archos can handle. I was prepared to do that for my M-Bus, but turned out easier. My friends are doing this for a VW adapter. > Too bad, I found a sony head changer at 105 euros. You already got that?
