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 DS2400N 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.
