I have designed and built an adapter between the Jensen marine wried remote and
an RS-232 connect intended to connect to my Mk2 player, but I can't get the
female connector on the sled to listen to my commands.

To debug, I have been trying to get hyperterminal to talk to the sled connector.
I can get the male connector on the unit to work fine, but the same stuff
dosn't work on the sled connector. All I get are the boot up messages.

I buzzed out the female DB-9 to the docking connector and found that
the pinout is messed up. Here is what I got:

DB9 pin = Sled Pin = Function
5 = tel. mute. = gnd
3 = yellow = txd
4 = blue = ?
7 = lts. on = ?

As you can see, pin 2 is missing and that should be the RXD pin.
Nither of the other two pins seem to work as the RXD pin.
When looking at the TXD pin, I see the data come out for the boot
messages at 115K buad and then the pin
bounces up and down a few times and then floats. This makes me
think that the RS-232 port is getting disabled after boot.

What do I need to do to get this to work???
How are the light and mute controls muxed with the RS-232 port???

Thanks,

scott.
