2.6.2 Pass Through
When Pass Through is activated on the Auxiliary interface, the DS8100A reader can be
ed with a Lonworks
terface.
nnection mode allows two or more devices to be connected to a single external serial
terface. The DS8100A transmits the messages received by its auxiliary interface onto its
ain 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 plemented 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.
