5.2 Programmable trigger switch
The configuration software provides a choice of three functions each for the fully depressed and halfway positions of the
trigger switch.
Scan:
The switch position turns on the marker beam and scans a code.
Marker: The switch position turns on the marker beam.
None:
The switch position does nothing.
Note, however, that the setting for the halfway position overrides the one for the fully depressed position if it has a higher
priority--that is, appears earlier in the above list. Specifying "Scan" for the halfway position and "Marker" for the fully
depressed position, for example, produces scanning for both positions.
5.3 Software control
You can control the scanner by sending scanning control commands from the host PC via the RS-232C interface, instead
of pressing the trigger switch.
Scanning control commands include R, READON, LON, Z, READOFF and LOFF and are restricted by the trigger switch
operating modes, as listed below.
Commands
Ready-to-scan commands
R,
Upon receipt of one of these commands,
READON,
the scanner lights the illumination LEDs
LON
and becomes ready to scan.
Standby commands
Z,
Upon receipt of one of these commands,
READOFF,
the scanner turns off the illumination
LOFF
LEDs and switches to standby.
Each of these commands should be enclosed with a header and terminator for transmission according to the
communications conditions of the scanner.
