5.8 PASS-THROUGH
An alternative Pass-Through layout allows the more efficient ID-NET network to be used.
This layout is really an ID-NET Master/Slave Multidata layout which also allows
each
scanner (Master and Slaves) to accept input on the Auxiliary interface, for example to
connect a device such as a hand-held reader for manual code reading capability.
Each scanner transmits its own messages plus any messages received by its Auxiliary
interface onto the ID-NET interface. The Master passes all messages to the Host.
When On-Line Operating mode is used, the scanner is activated by an External Trigger
(photoelectric sensor) when the object enters its reading zone.

– Pass-Through On ID-NET Layout
NOTE:
The Master scanner connected to the Host can be alternatively
connected to a Fieldbus network using a Host Interface module through a
CBX500 connection box.
5.9 OTHER LAYOUTS
NOTE:
Other backward-compatible layouts are available such as: RS232
Master/Slave, RS232 Pass Through and Multiplexer. We recommend using
the more efficient ID-NET network for Master/Slave or Multiplexer layouts.
