Delta is only available when using PhotoStyle.(Default = 25)nD Range: 0 - 255L - 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 hand held. LED State is not availablewhen using Decoding Style.0L LEDs off(default)1L LEDs onT - Wait for Trigger: Waits for a hardware trigger pull before taking the image.0T Takes image immediately(default)1T Waits for a trigger pull, then takes the image. This option onlyworks with Imaging Style 1P (Photo Style). Refer to page 8-1.U - Update Tries: The maximum number of frames the imager should take toreach the Delta for Acceptance. Update Tries is only available when usingPhoto Style.(Default = 6)nU Range: 0 - 10W - Target White Value: Sets the target for the median grayscale value in thecaptured image. For capturing close-up images of high contrast documents,a lower setting, such as 75, is recommended. Higher settings result in longerexposure times and brighter images, but if the setting is too high, the imagemay be overexposed. Target White Value is only available when using PhotoStyle.(Default = 125)nW Range: 0 - 255% - Target Set Point Percentage: Sets the target point for the light and darkvalues in the captured image. A setting of 75% means 75% of the pixels areat or below the target white value, and 25% of the pixels are above the targetwhite value. Altering this setting from the default is not recommended undernormal circumstances. To alter grayscale values, Target White Value shouldbe used.(Default = 50)n% Range: 1 - 99Image Ship - IMGSHPAn image is taken whenever the trigger of the imager is pressed, or when theImage Snap (IMGSNP) command is processed. The last image is always storedin memory. You may “ship” the image by using the IMGSHP command.
