The SC09 cable is used to connect the PLC to a personal
computer for program development. The circular 8 pin port on
the PLC CPU module uses the RS422 standard of
communication. Most personal computers only have a RS-232
communication port. For this reason, the SC09 cable has a
conversion circuit built into the connector housing.
The cable includes hardware that converts from RS422 to RS232.
