ABR
All devices always support multiple output channels (that is, for data monitoring).
3.6.3 Pass-Through
The pass-through layout allows each device working alone, to collect data from one or more pass-through input channels
and send this data plus its own on one or more different output channels.
In this way independent devices can be connected together in combinations to create multi device networks. Many devices
reading independently can send their messages through a common output channel which instead of being directed at a
Host can be collected by another device on its pass-through input channel and sent to a Host on a different output channel.

= Pass-Through Input channel
= Output channel
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.
