FXT 009 standard RS232 cable wiring diagram

Does anyone know where I can find a wiring diagram of the standard RS232 cable supplied with the FXT009 modem?

I am having trouble with a remote customer configuration and I suspect not all pins are actually connected in their case. I am particularly interested in the DSR/DTR line connections as these can have special uses on the FXT009.

I have an older cable supplied with a Supreme 20 - but I am suspecting the cables are not actually the same.

The manual has drawings for four different setups - but does not mention which one is related to the actual cable they supply.


Sounds like you just need to buzz-out the connections using a continuity tester.

As you suspect cable problems, Even if someone did post a wiring diagram, you’d have to do that anyway to see if the cable you have is correct or not …
