INSTALLATION

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. 3.6.4 and 3.6.5) 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:

This interface is forced by software when the protocol selected is MUX32 protocol.

In a Multiplexer layout or for slaves, the Multidrop address must also be set via serial channel

by the Genius™ utility or by the Host Programming Mode.

Figure 23 shows a multidrop configuration with DS2100N scanners connected to a

Multiplexer.

CAUTION

This is an example of multidrop wiring. Consult the multiplexer manual for

complete wiring instructions.
