10. LED
The BHT has two LEDs, a display LED (red/blue) to notify the operator that barcode reading is complete, and a
charge LED (red/green) to notify the operator of the charge status.
The illumination status for the display LED can be controlled from the application.
The illumination status is set and acquired using a 2D indexer. The illumination device (display (barcode) LED only
on BHT-400) is specified for the first index, and the illumination color (red or green) is specified for the second
index.
[Ex.] Turn ON the red display LED.
[VB] MyLED. (LED.EN_DEVICE.BAR,LED.EN_COLOR.RED) _
= LED.EN_CTRL.ON
[C#]
MyLED[LED.EN_DEVICE.BAR,LED.EN_COLOR.RED]
= LED.EN_CTRL.ON
The priority order relationship is as follows:
(Barcode read based control) > (application based control)
If “Turn ON LED when barcode reading complete.” is specified and barcode reading is enabled, the display LED
illumination status cannot be controlled from the application until barcode reading is next disabled.
The illumination request from the application, however, is retained in the variable flag (RAM) inside the LED driver.
Illumination requests are also set and cleared while barcode reading is enabled. When barcode reading is
disabled, the flag is checked and the LED color for which an illumination request exists is turned ON automatically.
