6.4 ID-NET™ NETWORKS
6.4.1 M/S Synchronized Serial Host
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 the RS232/RS485 main serial interface.
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.
Figure 90 – ID-NET™ M/S Synchronized Layout
The Master reader can be connected to the CBX series connection box with the advantage
of the External Memory Backup and Restore features (CBX + BM100 module). If the Backup
and Restore function is not required, then a QL300 can be used to connect the master
reader.
