Reference Manual
Note: When printing barcodes, keep each Macro PDF sequence separate, as each has a
unique identifier. Do not mix barcodes from several Macro PDF sequences, even if
they encode the same data. When you scan Macro PDF sequences, scan the entire
Macro PDF sequence without interruption!
Image Capture Disable
Image Capture
Illumination
Decide whether to flash illumination on every image
capture to aid decoding.
 Turn On (Internal LED )
 Turn Off
On
Image Capture
Autoexposure
Decide whether to manually specify the gain and exposure
time (only recommended for advanced users with difficult
image capture situations).
On
Gain Time Only applies when Image Capture Autoexposure is
disabled.
 Gain is a means of amplifying the raw image data
before it is converted into 256 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.
 Set the manual gain time in the range of 79~127.
100
Exposure Time Only applies when Image Capture Autoexposure is
disabled.
 Exposure Time controls the amount of time the CCD is
allowed to collect light, much like the shutter speed for
a camera.
Generally, the brighter the environment, the
lower the exposure time. Increasing the exposure time
past 20 ms in a handheld application increases the risk
of blurring the image due to hand jitter.
 Set the manual exposure time to one of the following
values — 5 ms, 10 ms, 15 ms, 20 ms, 25 ms, or 30
ms.
10 ms
Snapshot Aiming
Pattern
Decide whether to project the aim pattern while capturing
an image.
On
Image Resolution Decide how to alter image resolution before compression.
Multiple pixels are combined to one pixel, resulting in a
smaller image containing the original content with reduced
resolution.
 640×480 (Full resolution)
 320×240 (Half resolution)
 212×160 (1/3 resolution)
 160×1420 (1/4 resolution)
640×480
Image Format Decide in which file format the image is saved.
 JPEG file format
 BMP file format
