Does anyone know the cable pinout for the console or async ports found on the CCF card?

Thanks!!

Same as a modem cable pin 2 and 3 are reversed

Thanks for the reply.

I actually need all 9 of the pinouts if possible. I don't have access to a technicians manual for the 250 or 350 and can't find any "usefull" info in the admin manuals about cable pinouts.

I am trying to connect one of the async ports to a Gordon Kapes site monitor and need to know what pins CTS, GND, DTR, DSR, & RTS are on.

I also don't have a breakout box to find them on my on.

You only get 3 pins out of the CCF card on an async port

pin 2 is transmit data pin 3 is receive data and pin 5 on a 250 is signal ground.


Most modems require DTR asserted to answer a call. The AT&D0 command should allow the modem to answer without DTR. Refer to the documentation provided by the modem manufacturer.
