The master scanner is also connected to the host on the RS 232 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.

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

Figure 5.19

RS 485 master/slave layout

The termination resistors of the RS 485 bus must not be installed.

It is necessary to bring the external trigger signal to all the scanners.

The auxiliary serial port of the slave scanners can be used in local echo
communication mode to control any single scanner (visualise collected
data) or to configure it using the VisoSetup utility or host mode
programming procedure
