I'm working on a Fanuc 16-TTA that has a dead serial port.
I'd really like to know how to turn on the optional second serial port (marked RS232-2 on the main board).
Right now if I set IO channel to 2 or 3 and try to READ or PUNCH nothing happans (no LSK, no error messages, nothing).
I'm assuming in order to use the second serial port I will have to enable an option parameter, then use IO channel 2, correct?
Thanks,
Alex.
