Cabling and adapter pinouts

Cabling and adapter pinouts

Under Channel 0 emulation, the configured serial port on the computer running the software acts like the Channel 0 port on a processor.
The following diagram shows the basic cabling for Channel 0 emulation. On PLC-5 processors, Channel 0 is a 25-pin female connector (requiring a 25-pin male connector on the cable). The cabling is basically straight-through, with a null modem on one end of the cable.



For serial devices and computers with 9-pin serial ports, use the Rockwell Software C13 or C13B adapters. The following diagrams show the pinouts for these adapters.




To connect to Channel 0 of a SLC 500 processor, use a null-modem (transmit and receive lines are swapped on one end) nine-pin to nine-pin serial cable, available at most electronics stores.
