2.3.2 Main Serial Interface - RS485 Half-Duplex

The RS485 half-duplex interface (3 wires + shield) is used for polled communication

protocols.

It can be used for Multidrop connections in a master/slave layout or with a Datalogic

Multiplexer, (see par. 2.5.2 and 2.5.3) 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:
