5.4.3 RS485 Half-Duplex Interface
NOTE
This interface is provided for backward compatibility. We recommend using
the more efficient ID-
NET™ network for Master/Slave or Multiplexer layouts.
The RS485 half-duplex (3 wires + shield) interface is available for polled communication
protocols.
It can be used for Multidrop connections with a Datalogic Multiplexer, (see par.
6.5
) exploiting
a proprietary protocol based on polled mode called MUX32 protocol, where a master device
polls slave devices to collect data.
The following pins of the 25-pin connector are used for RS485 half-duplex communication:

This interface is forced by software when the protocol selected is MUX32 protocol.
In a Multiplexer layout, the Multidrop address must also be set via serial channel by the
VisiSet™ utility or by the Host Programming Mode.
