  You would want Rx audio from 2 and 7, Tx audio in on 4 and 8, solder 
bead D in the radio.

I dont recall if there is a VOX option in the radio. If the intercom is 
full duplex, how will you key up the radio (PTT)?

DB9
1Dimmer in
2De-Emph Audio Out (affected by Vol Pot)
3Discriminators Audio (Un Squelched)
4Tx Mod In
5PTT in
6COR out (probably need a pull up resistor)
7Ground
8Ground
9Ground

Pin 2 - You can set a minimum level via Set Mode
Pin 4 - Tx freq response. Solder bead F for data, solder bead D for audio
Pin 5 - Enable external PTT via software. CommonExpertEPTT
Pin 6 - Enable COR via software. Disable the 2/5 tone function for the 
selected channel.  CommonExpert RX EXO to ON, and delay timer to OFF
