Chapter 5 Scanning Control
Two types of scanning controls are available--Trigger switch control and Software control.
Trigger switch control: Pressing the trigger switch readies the scanner for scanning.
Software control: Instead of pressing the trigger switch, you send control commands from the host computer via the
RS-232C interface to ready the scanner for scanning or put the scanner on standby.

Trigger Switch Control
Pressing the trigger switch turns on the illumination LED and readies the scanner for scanning. The scanner supports
the following five trigger switch operating modes. Select the one that best meets your needs using the bar-coded
parameter menu or the configuration software (ScannerSetting).
(1) Auto-off mode 1
Holding down the trigger switch lights the illumination LED for the specified period (selectable from 1 to 5 seconds in
one second increments with the configuration software (ScannerSetting)), during which the scanner is ready to scan.
When a bar code is read successfully or the specified period has elapsed, the illumination LED goes off and the
scanner switches to standby.
(2) Auto-off mode 2
If you press the trigger switch, the illumination LED lights for approx. 5 seconds during which the scanner is ready to
scan, regardless of whether a bar code is read successfully or the trigger switch is released.
After a bar code is read successfully, the ready-to-scan state further continues for approx. 5 seconds.
If the scanner is left without scanning operation for approx. 5 seconds, it turns off the illumination LED and switches
to standby.

(3) Momentary
Only while you hold down the trigger switch, the illumination LED lights and the scanner is ready to scan.
When you release the trigger switch or a bar code is read successfully, the illumination LED goes off and the scanner
switches to standby.

(5) Continuous reading mode
When you turn the scanner on, the scanner lights the illumination LED and becomes ready to scan. The scanner
ignores all trigger switch input.
When you are setting parameters using the bar-coded parameter menu, the scanner is always in the
