DX8200A

2.5.2 Pass Through

When Pass Through is activated on the Auxiliary interface, the DX8200A reader can be

integrated in a network consisting of different scanners not provided with a Lonworks

interface.

This connection mode allows two or more devices to be connected to a single external serial

interface. The DX8200A transmits the messages received by its auxiliary interface onto its

main interface.

In this configuration a series of scanners can be connected together using RS232 on the

main interface and all messages will be passed through this chain to the host. The reading

phase of each scanner is independent from the others. In Pass Through connections each

scanner is provided with its relative External Trigger (multi P.S.).

Applications can be implemented to connect a device such as a hand-held reader to the

Auxiliary port for manual code reading capability.

For the RS232 connections the maximum cable length is 15 m (50 ft).

The DS4600A scanners represented in the following figures are configured in Pass Through

mode.
