PASS-THROUGH
Pass-through mode allows two or more devices to be connected to a single external serial
interface.
Each VB24 transmits the messages received by the Auxiliary interface onto the Main
interface. All messages will be passed through this chain 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.
Applications can be implemented to connect a device such as a hand-held reader to the
Auxiliary port of the last scanner in the chain for manual code reading capability.
The Main and Auxiliary ports are connected as shown in the figure below:
