Imaging Commands
The scan engine is like a digital camera in the way it captures, manipulates, and transfers images. The following commands
allow you to alter the way the scan engine performs these functions.
Single-Use Basis
Imaging Commands with their modifiers send instructions to the scan engine on a single-use basis, and take effect for a single
image capture. Once that capture is complete, the scan engine reverts to its imaging default settings. If you want to perma-
nently change a setting, you must use the serial default commands (see Chapter 10). When the serial default command is
used, that selection becomes the new, permanent setting for the scan engine.
Command Syntax
Multiple modifiers and commands can be issued within one sequence. If additional modifiers are to be applied to the same
command, just add the modifiers to that command. For example, to add 2 modifiers to the Image Snap command, such as set-
ting the Imaging Style to 1P and the Wait for Trigger to 1T, you would enter IMGSNP1P1T.
Note: After processing an image capture command (IMGSNP or IMGBOX), you must follow it with an IMGSHP command if you
want to see it on your terminal.
To add a command to a sequence, each new command is separated with a semicolon. For example, to add the Image Ship
command to the above sequence, you would enter IMGSNP1P1T;IMGSHP.
The imaging commands are:
Image Snap - IMGSNP (page 7-1)
Image Ship - IMGSHP (page 7-3)
Intelligent Signature Capture - IMGBOX (page 7-10)
The modifiers for each of these commands follow the command description.
Note: The images included with each command description are examples only. The results you achieve may be different from
those included in this manual. The quality of the output you receive will vary depending on lighting, quality of the initial
image/object being captured, and distance of the scan engine from the image/object. To achieve a high quality image, it
is recommended that you position your scan engine 4-6" (10.2-15.2 cm) away from the image/object you are capturing.
Step 1 - Take a Picture Using IMGSNP
Image Snap - IMGSNP
An image is taken whenever the hardware button is pressed, or when the Image Snap (IMGSNP) command is processed.
The image snap command has many different modifiers that can be used to change the look of the image in memory. Any num-
ber of modifiers may be appended to the IMGSNP command. For example, you can use the following command to snap an
image, increase the gain, and have the beeper sound once the snap is complete: IMGSNP2G1B
IMGSNP Modifiers
P - Imaging Style
This sets the Image Snap style.
0P Decoding Style. This processing allows a few frames to be taken until the exposure parameters are met. The last
frame is then available for further use.
1P Photo Style (default). This mimics a simple digital camera, and results in a visually optimized image.
2P Manual Style. This is an advanced style that should only be used by an experienced user. It allows you the most
freedom to set up the scan engine, and has no auto-exposure.
B - Beeper
Causes a beep to sound after an image is snapped.
0B No beep (default)
