5.6 ID-NET SYNCHRONIZED NETWORK
When the device is
working Synchronized , the ID-NET connection is used to collect data
from several readers to build a multi-point or a multi-sided reading system; there can be one
Master and up to 31 Slaves connected together.
The Slave readers are connected together using the ID-NET interface. Every Slave reader
must have an ID-NET address in the range 1-31.
The Master reader is also connected to the Host on one of its communication channels. In
the following examples the RS232/RS422 main serial interface is used.
For a Master/Slave Synchronized layout the External Trigger signal is unique to the system;
there is a single reading phase and a single message from the Master reader to the Host
computer.
It is not necessary to bring the External Trigger signal to all the readers.
In the Master/Slave Synchronized layout the Master operating mode can only be set to
Phase Mode.
The Main and ID-NET interfaces are connected as shown in the following figures.

– ID-NET Synchronized Layout
The Master reader can be connected to the CBX series connection box with the advantage
of the Backup and Restore configuration function (CBX + BM100 module).
All devices always support multiple output channels (i.e. for data monitoring).
