PASS THROUGH
When Pass Through is activated on the Auxiliary interface, the DS6300 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 DS6300 transmits the messages received by its auxiliary interface onto its
main interface. The received data is transmitted "as is", (passed-through), and therefore any
data formatting requirements must be made at each individual reader.
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 scanners represented in the following figures are configured in Pass Through mode.
