Auxiliary Port Protocol
Auxiliary Port Protocol
Note: The Aux Port cannot be used when the host port is set to RS-422 or Multidrop .
As with the host port parameters, the auxiliary terminal’s settings (baud rate, parity, stop
bits, and data bits) must be identical with those of the auxiliary device.
Aux Port Mode
Note: The Aux Port interacts only with the host port via the 25-pin port except when in
Daisy Chain mode. When in Daisy Chain mode, the Aux Port will also interact with the
configuration port (9-pin port) or the wiring box network ports.
Usage:
These commands set the communication parameters with the auxiliary port
which can be used to configure menus, send data to the host, display data
transmissions originating from the host of the scanner, and relay data from
other scanners set in tandem (Daisy-Chained). If the scanner’s host port
needs to be dedicated to the host, but configuration must be done on the fly,
the auxiliary port can be set to accept configuration changes by Command
Processing.
Definition:
An auxiliary port connects the scanner to a remote display or to other scanners
that can display or transfer data. As with the host port parameters, the auxiliary
terminal’s settings (baud rate, parity, stop bits, and data bits) must be identical
to those of the auxiliary device.
Definition:
Determines the flow of data between the auxiliary port device(s), the scanner,
and the host.
