Figure 14. Pass-Through Layout
In a Pass-through layout each device supports multiple pass-through configurations to accept input from different devices
on different channels (middle reader, above). However, readers are not required to have a pass-through configuration if they
don’t need to receive data from an input channel (right reader, above). The overall data collection device always has at least
one pass-through configuration to collect the input data from the other devices and send it to the Host (left reader, above).
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
Multidata Network (Pass-Through)
A special case of the pass-through layout allows each Slave device working alone, to collect data from one or more pass-
through input channels and send this data plus its own on the ID-NET output channel to the Master.
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 collects the data from its pass-through ID-NET input channel and sends it to the Host on a different output
channel.
