Is the serial RS232 cable you use to connect to a SLC process a special cable? I was told it is, but in the past ive used 2 different cables that were not AB, just normal serial cables and they both worked.
I'll guess here. If you are connecting a PC/Laptop to a SLC with a serial port (RS232 port ) then use a null modem cable. It does not have to be made by AB.
Some more info and we will not have to guess. What are you connecting the SLC to.
