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 scanner ’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.
