It's only a 3 pin serial connection so this would imply that you only need ground, Rx and Tx. The pinout on the db9 connector is:
pin 2 - Rx
pin 3 - Tx
pin 5 - Gnd
I'd imagine the black wire is ground with Tx and Rx being on the 2 remaining wires. It doesn't usually matter if you get Tx/Rx around the wrong way but it won't work properly. If this happens just reverse the Tx/Rx and it should work okay.
Of course you do this at your own risk, but if someone could give the exact pinout it'd be much less risky 
Anyone tried this yet?
Or could anyone please confirm this.....?
