RS485 Full-Duplex Interface
The RS485 full-duplex (5 wires + shield) 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 following pins of the Main Interface connector (Figure A, 15) are used for RS485
full-duplex communications:
