RS485 Full-Duplex Interface
The RS485 full-duplex interface is used for non-polled communication protocols in
point-to-point connections over longer distances (max 1200 m / 3940 ft) than those
acceptable for RS232 communications or in electrically noisy environments. The connections
to the Host can be made as follows:
 through the PWO (in which case a CAB-SC6103 cable connects the PWO to the
SC6000)
 directly to the SC6000
See also par. 2.5.1.
The following pins of the 9-pin connector are used for RS485 full-duplex interface
connection:
