Chapter 6 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. (Refer to Section 6.1.)

Software control: Instead of pressing the trigger switch, you send control commands from the host computer via the

RS-232C or USB-COM interface to ready the scanner for scanning or put the scanner on standby. (Refer to Section

6.2.)

In addition, the auto sensing mode is also available. (Refer to Sections 6.3 and 6.4.)

6.1 Trigger Switch Control

Pressing the trigger switch turns on the illumination LEDs 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 QR-coded

parameter menu or the configuration software (ScannerSetting_2D).

(1) Auto-off mode

Holding down the trigger switch lights the illumination LEDs for a maximum of 5 seconds, during which the scanner

is ready to scan.

When a code is read successfully or approx. 5 seconds have elapsed, the illumination LEDs automatically go off and

the scanner switches to standby.

If the trigger switch is released within approx. 5 seconds, the scanner switches to standby.

(2) Momentary switching mode

Only while you hold down the trigger switch, the illumination LEDs light and the scanner is ready to scan.

When you release the trigger switch or a code is read successfully, the illumination LEDs go off and the scanner

switches to standby.

(3) Alternate switching mode

Each time you press the trigger switch, the scanner toggles between the ready-to-scan and standby states.

(4) Continuous reading mode 1

When you turn the scanner on, the scanner lights the illumination LEDs and becomes ready to scan. The scanner

ignores all trigger switch input.

If the scanner receives the Z, READOFF or LOFF command, it switches to standby; if it receives the R, READON or

LON command, it becomes ready to scan.

You can select whether or not the scanner transmits the ERROR command when the scanner cannot complete

scanning and switches to standby, using the configuration software (ScannerSetting_2D).

(5) Continuous reading mode 2

This mode is functionally equivalent to the continuous reading mode 1, except that the scanner waits for a command

upon completion of scanning. To become ready to scan, the scanner should receive the Z, READOFF or LOFF

command to switch to standby and then receive the R, READON or LON command.

You can select whether or not the scanner transmits the ERROR command when the scanner cannot complete

scanning and switches to standby, using the configuration software (ScannerSetting_2D).

Note: When you are setting parameters using the QR-coded parameter menu, the scanner is always in the auto-off mode

regardless of the trigger switch operating mode selected.
