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 imager is in a stand. LED illumination (1L) is preferred

when the imager is handheld. LED State is not available when using Decoding

Style (0P).

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 imager takes to record an image. On a bright

day, exposure 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.
