RS485 Half-Duplex Interface
The RS485 half-duplex (3 wires + shield) interface is used for polled communication
protocols.
It can be used in a master/slave layout or for Multidrop connections with a Datalogic
Multiplexer, (see par. 2.5.4 and 2.5.5) exploiting a proprietary protocol based on
polled mode called MUX32 protocol, where a master device polls slave devices to
collect data.
The connector pinout follows:
