Imager Preferences 5 - 11
Gain
Parameter # F4h F0h A7h
This parameter only applies when Decoding or Image Capture Autoexposure is disabled. Gain is a means of
amplifying the raw image data before it is converted into 8-bit grayscale values. Increasing the gain increases
brightness and contrast, but also increases noise (undesired electrical fluctuations in the image) which makes the
image less attractive and/or harder to decode.
To set the manual gain, scan the bar code below followed by 3 bar codes from Appendix D, Numeric Bar Codes , in
the range of 1 to 100, representing the value. The default is 100.
Exposure Time
Parameter # F4h F1h 37h
This parameter only applies when Decoding or Image Capture Autoexposure is disabled. It configures the
exposure for both Decode and Snapshot modes.
Each integer value represents 100
μ
s worth of exposure. The default value is 10 which results in an exposure
setting of 1 ms.
To set the Exposure Time parameter, scan Fixed Exposure followed by four numeric bar codes representing the
value in the range of 1 - 1000. Insert leading zeros if necessary. For example, to set a Fixed Exposure value of
9.9 ms, scan 0, 0, 9, 9. See
Appendix D, Numeric Bar Codes for numeric bar codes.
