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 figure below.

programming procedure.
The termination resistors of the RS485 bus must not be installed.
