Indicator LEDs

The indicator LEDs light or flash in blue, green or red as described below.
The indicator LEDs light in blue when:
- the scanner has read a code successfully,
- the "Start setting" or "End setting" code is read from the QR-coded parameter menu (given in Chapter 11),
- the scanner starts or ends a sequence of split QR Code scanning,
- the scanner has read a split QR Code symbol, or
- the parameter values are saved by a PW command (refer to Appendix 2).
The indicator LEDs light in red when:
- the scanner has received an abnormal control command,
- the scanner has failed to edit data read,
- the scanner has read split QR Code symbols in edit mode and the accumulated data exceeds 8 kilobytes,
- the scanner has failed to save parameter values specified with the configuration software (ScannerSetting_2D),
QR-coded parameter menu, or control commands,
- a code other than a parameter setting code is read during parameter setting by the QR-coded parameter menu,
- a transmission error or timeout occurred when the scanner was communicating with the configuration software
(ScannerSetting_2D) , or
- a run-time error has occurred in ADF script.
The indicator LEDs can be disabled with the QR-coded parameter menu or configuration software
(ScannerSetting_2D). In any of the following cases, however, the indicator LEDs come on regardless of the current
LED setting.
- When the scanner is being customized with the QR-coded parameter menu (Chapter 11),
- When the scanner receives an LED-ON command (ID) from the host computer (refer to Appendix 2),
- When the configuration software (ScannerSetting_2D) starts up or any setting is newly established,
- When the scanner reads a batch-process QR Code symbol,
- When the parameter values are saved by a PW command (refer to Appendix 2),
- When the scanner has failed to save parameter values specified with the configuration software
(ScannerSetting_2D), QR-coded parameter menu, or control commands, or
- When a run-time error has occurred in ADF script.

Illumination LEDs

When the scanner is ready to scan, the illumination LEDs flash.
The illumination LEDs provide the three choices--Always ON, Automatic, Always OFF by using the configuration
software (ScannerSetting_2D).
