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.

Figure 66 - ID-NET Multidata Layout (Pass-through)
In a Pass-through layout each device supports multiple pass-through configura-
tions to accept input from different devices on different channels (i.e. Master
reader above). However, ID-NET Slave readers are not required to have a pass-
through configuration if they don’t need to receive data from an input channel
(i.e. 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.
