I can not set up comms via Port 1 on a V700 Unit to a  Cybertec SMM-400 Modem for SMS purposes.

Have set them Modem Serial Setting to 9600,8,n,1

I have check the Serial Port settings in the PLC via Information Mode.   PCOM,RS232,9600,8,n,1

When ever I Init the Mode, It always returns "Modem operation Failed - Modem not connected"


Firstly has anyone used the  Cybertec SMM-400 Modem successfully before and if so can you please provide the PIN OUT for the cable.

I have tried using "Putty" on the output from Port 1 when doing a Modem Init but nothing is transmitted..is this normal.?


Thanks in advance
