Imaging Commands

The document reader is like a digital camera in the way it captures, manipulates, and transfers images.  The following commands 

allow you to alter the way the document reader performs these functions.

Single-Use Basis

Imaging Commands with their modifiers send instructions to the document reader on a single-use basis, and take effect for a 

single image capture.  Once that capture is complete, the document reader reverts to its imaging default settings.  If you want to 

permanently change a setting, you must use the serial default commands (see 

Chapter 2

).  When the serial default command is 

used, that selection becomes the new, permanent setting for the document reader.

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 setting 

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 or IMGACP 

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 1-1)

Image Ship - IMGSHP

 (page 1-5)

Intelligent Signature Capture - IMGBOX

 (page 1-14)

The modifiers for each of these commands follow the command description.

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.  Modifiers 

always begin with numbers and end with a letter (case insensitive).  Any number 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 document reader, and has no auto-exposure.

B - Beeper

Causes a beep to sound after an image is snapped.

0B

No beep 

(default)

1B

Sounds a beep when the image is captured.
