Note
When an indicator LED (=BAR) is specified as "device," selection of the color yellow (=YELLOW) is
ignored.
In general, indicator LEDs cannot be controlled from the application while barcode reading is enabled.
However, if prohibition of operation for a particular indicator LED is specified, it can be controlled from
the application.
Once an LED is turned on from the application, it will remain lit, even after the application is
finished, until it is deliberately turned off.
[Ex.] Turn ON the blue LED.
[VB] MyLED(LED.EN_DEVICE.BAR, LED.EN_COLOR.BLUE) = LED.EN_CTRL.ON
[C#] MyLED[LED.EN_DEVICE.BAR, LED.EN_COLOR.BLUE] = LED.EN_CTRL.ON;
