Datalogic Matrix 300N - RS422 Full Duplex Interface

66 Matrix 300N
RS422 Full Duplex Interface
The RS422 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 CBX pinout follows:

For applications that do not use RS422 transmission to the reader (terminal block RX+
and RX- signals), do not leave these lines floating but connect them to SGND as
shown below.
