Full Duplex Mode
In full duplex mode, all aux port data and bar code data is sent directly to the host.
Bar code data is not displayed on the aux port screen.
Data initiated from the Aux Port
• Aux port data is passed directly through to the host when-
ever it is received by the scanner, unless the scanner is in
a polled mode, in which case the data will be ignored.
• Aux Port data is not echoed.
• Aux Port data to the host will not have a preamble or a
postamble.
• A <D> command is the only command accepted by the
scanner from the aux port. All other commands will pass through to the host.
Data initiated from the Scanner
• Scan data is not sent to the aux port.
Data initiated from the Host
• In polled mode, data echoed from the host to the aux port
must be in the format <B____> (for example, to send the
word “LUNCH” to the terminal, it must be sent in the for-
mat <BLUNCH>).
• In unpolled mode, all host data is echoed to the aux port.
