TYPICAL LAYOUTS
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 DS4800 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.
