Illumination LED and Aimer
The terminal integrates the illumination LED for lighting and the Aimer for focusing a symbol to
scan. Setting the intensity of the illumination LED to zero will turn off.
This setting is useful when the terminal is used outdoors where the illumination LED is not
needed, or when a stamp in red is to be read.
The functions of the Imager Library relevant to the "Illumination LED and Aimer" are as follows.
IMGAimerOn
IMGIlluminationOn : Turns on or off the illumination LED.
Imager's APO
This function will shut down the power automatically to the CMOS Imager if it has not been used
(reading a symbol, capturing image, extracting signature, streaming) for a while.
After activating the APO (Automatic Power OFF) function, the imager's power can be turned on
again if one of the following functions is invoked. The time period of the APO function can be set
up in the range of 0 to 1,800 seconds. Specifying "0" will disable it.
The power consumption by the imager can be curbed while the APO function is activating.
However, note that it takes about 30 milliseconds to put the power back on.
The functions of the Imager Library relevant to the "Imager's APO" are as follows.
IMGSetImagerAPO
IMGGetImagerAPO : Retrieves time period for Auto Power Off.
