Timeout

Set the amount of time the decoder remains in Image Mode. The decoder exits Image Mode upon

a trigger event, or when the Image Mode Timeout elapses. By default, the time-out value is set to

30 seconds.

Gain/Exposure Priority

Alter the decoder’s gain/exposure priority when it acquires an image in Image Mode with auto

exposure enabled.

 Low Gain Priority: The decoder favors longer exposure time rather than higher gain to capture

an image. This ensures that the image is less noisy and produces fewer artifacts during

post-processing activities like image enhancement (sharpening). This mode is ideal for fixed

mount/fixed object image capture since the image acquired is susceptible to motion blur.

 Low Exposure Priority: The decoder favors higher gain over exposure to capture an image.

This results in an image that is less susceptible to motion blur at the expense of noise

artifacts. However, for most applications, the amount of noise is acceptable.

Preview before Image Capture

Decide whether to enable Image Mode with View Finder, which the decoder behaves as a video

camera until a trigger event is activated.

 Select the number of 100-byte blocks. Values range from 800 to 3000 bytes. Selecting a

smaller value transmits more frames per second; selecting a larger value increases video

quality. By default, it is set to 1700 bytes.

JPEG Image Options

Optimize JPEG images for either size or quality.

 JPEG Target File Size: Specify the target JPEG file size in terms of 1 Kilobytes (1024 bytes). By

default, it is set to 160 Kilobytes

 JPEG Quality: Specify the JPEG quality value (5~100). By default, it is set to 65.

Crop to Pixel Address

This is used to crop a captured image to the pixel addresses specified. When no cropping, it

presents the full 1280 x 1024 pixels for 1704.

 For image cropping on 1704, set the pixel addresses from (0,0) to (1279, 1023) to crop to.

Columns are numbered from 0 to 1279, rows from 0 to 1023. Specify four values for Top, Left,

Bottom, and Right, where Top and Bottom correspond to row pixel addresses, and Left and

Right correspond to column pixel addresses. For example, for a 4 row x 8 column image in the

extreme bottom-right section of the image, set the following values:

Top = 1020, Bottom = 1023, Left = 1272, Right = 1279

Note: The scanner has a cropping resolution of 4 pixels. Setting the cropping area to less

than 3 pixels transfers the entire image.

1.13.2 DECODE MODE

By default, this is the normal operation mode. The decoder attempts to locate and decode

any barcode within its field of view upon a trigger event. Refer to

1.1 Scan Mode.
