Fortuna PS/2 socket pinouts

[Merlin2005]

Hi

I have a Fortuna GPS antenna which has an inline PS/2 socket. I would like to know what the pinouts are on the socket so that I can repair a car charger / power lead for my iPaq 4700. the cable came out of the iPaq plug after being pulled accidentally and I don't know how they connect inside the Himalaya plug to the iPaq. I have details of the iPaq pinouts, so all I need to repair it is the connections to the PS/2 socket for power and signal. It looks as if only two signal wires were connected inside the plug, however I don't know if the antenna uses RS-232 or TTL which affects the pins I connect the wires to. Can anyone enlighten me?

Thanks

Taken from the Fortuna U2 Manual. It doesn't make a lot of sense to me, can anyone please tell me how this translates into RS232 TX / RX data?
