Managed to leave mine plugged in and got the serial port end ripped off and lost. Anyone know where the 4 wires from the wideband connect on the DB9 connector. Or have one I could borrow.

Normally all you need for a serial connection is 5(gnd) 2 and 3. Can't remember which way round the tx and rx are though.

This any use?
