Trying to communicate with an allen bradley slc 100 using a homemade interface cable. I have a B&B Electronics RS-232 to RS-422 converter, model 422lp9tb and have it connected as per their instructions and used the A-B 8 pin pinout obtained from this forum, however my laptop keeps telling me cannot communicate with slc. I am using Windows 95 through the serial port. I have tried to connect the converter straight and nulled but no luck. I have it connected:
Converter SLC
Tx-....................Rx- pin 2
Tx+....................Rx+ pin 1
Rx-....................Tx- pin 3
Rx+....................Tx+ pin 8
Have tried reversing it also.
It is frustrating, I am trying to avoid the $150 cable so any help would be greatly appreciated.
