L - LED State
Determines if the LEDs should be on or off, and when. Ambient illumination (0L) is
preferred for taking pictures of color documents, such as ID cards, especially when
the scanner is in a stand. LED illumination (1L) is preferred when the scanner is
handheld. LED State is not available when using Decoding Style (0P).
0L LEDs off (default)
1L LEDs on
E - Exposure
Exposure is used in Manual Style only (2P), and allows you to set the exposure
time. This is similar to setting a shutter speed on a camera. The exposure time
determines how long the scanner takes to record an image. On a bright day, expo-
sure times can be very short because plenty of light is available to help record an
image. At nighttime, exposure time can increase dramatically due to the near
absence of light. Units are 127 microseconds.
