2.5.2 RS485 Master/Slave

The RS485 master/slave connection is used to collect data from several scanners to

build a multi-point or a multi-sided reading system; there can be one master and up

to 5 slaves connected together.

The Slave scanners are connected together using the RS485 half-duplex main serial

interface. Every slave scanner must have a multidrop address in the range 0-4.

The master scanner is also connected to the Host on the RS232 auxiliary serial

interface.

The External Trigger signal is unique to the system; there is a single reading phase

and a single message from the master scanner to the Host computer.

It is necessary to bring the External Trigger signal to all the scanners.

The main and auxiliary ports are connected as shown in the following figure.
