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. 2.6.2 and 2.6.3) exploiting a proprietary protocol based on
polled mode called MUX32 protocol, where a master device polls slave devices to
collect data.
