Figure 15. ID-NET Multidata Layout (Pass-Through)
In a Pass-through layout each device supports multiple pass-through configurations to accept input from different devices
on different channels (Master reader, above). However, ID-NET Slave readers are not required to have a pass-through
configuration if they do not need to receive data from an input channel (right reader, above). The ID-NET Master always has
at least one pass-through configuration to collect the ID-NET Slaves data and send it to the Host.
Note: Slave devices cannot receive data from a pass-through ID-NET input channel and Master devices
cannot send data on an ID-NET output channel.
All devices always support multiple output channels (that is, for data monitoring).
In a Pass-through layout each device can have a different operating mode: Continuous, One Shot, Phase Mode, etc.

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.
