3.10.2 RS422 Full-Duplex Interface
The RS422 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 following positions of the CBX510 spring clamp connector (row 4) are used for RS422
full-duplex interface connection:
Name

IMPORTANT: For applications that do not use RS422 RX signals, do not
leave these lines floating but connect them to SGND as shown below.
