RS-232 Host Commands

The RS-232 interface will accept commands from the host. Available commands are:

•Disable Scanner

•Enable Scanner

•Reset Scanner

•Beep Good Read Tone

•Force Good Read

•Xon

•Xoff

Disable Scanner (ASCII ‘D’) - places the scanner in an operational mode in which the scanner does not accept bar code data input from the scan optics. NOTE: The scanner will complete any message transmission in progress to the host.

Enable Scanner (ASCII ‘E’) - places the scanner in an operational mode in which the scanner will accept label data input from the scan optics.

Reset Scanner (ASCII ‘R’) - performs a scanner reset operation. Any bar code data the scanner may be holding in buffers is discarded. NOTE: After reset is executed, additional host commands may be ignored for 30 seconds.

Beep Good Read Tone (ASCII ‘B’) - causes the beeper to sound one ‘good read’ tone if the beeper is enabled (see the section in this manual titled, “General Features” for more information about setting the scan- ner’s beeper functions).

Force Good Read Tone (Hex ‘01’) - causes the beeper to sound one ‘good read’ tone even if the beeper is configured as disabled.

Xoff (Hex ‘11’) - suspends current data transmission from the scanner to the host or prevents future data transmissions from occurring.

Xon (Hex ‘13’) - permits resumption of data transmission from the scanner to the host that was previously suspended via the Xoff command.
