R - Resolution of Signature Capture Area
The resolution is the number of pixels that the scanner outputs per each minimum bar width.  The higher the value for R, 
the higher the quality of the image, but also the larger the file size.  Values begin at 1000.  The scanner automatically 
inserts a decimal point between the first and second digit.  For example, use 2500 to specify a resolution of 2.5.  Set to zero 
when using the A and B modifiers (see A...

X - Horizontal Bar Code Offset
The horizontal bar code offset allows you to offset the horizontal center of the signature capture area.  Positive values move 
the horizontal center to the right and negative values to the left.  Measurements are in multiples of the minimum bar width.  
Y - Vertical Bar Code Offset
The vertical bar code offset allows you to offset the vertical center of the signature capture area.  Negative numbers indi-
cate that the signature capture is above the bar code, and...

Keyboard Function Relationships
The following Keyboard Function Code, Hex/ASCII Value, and Full ASCII “CTRL”+  relationships apply to all terminals that can 
be used with the scanner.  Refer to page 2-17 enable Control + X (Control + ASCII) Mode.
The last five characters in the Full ASCII “CTRL”+ column  ( [  ] 6 - ), apply to US only.  The following chart indicates the equiva-

Utilities
To Add a Test Code I.D. Prefix to All Symbologies
This selection allows you to turn on transmission of a Code I.D. before the decoded symbology.  (See the Symbology Charts, 
beginning on page A-1) for the single character code that identifies each symbology.)  This action first clears all current prefixes, 
then programs a Code I.D. prefix for all symbologies.  This is a temporary setting that will be removed when the unit is power 
cycled.

Test Menu
When you scan the Test Menu On code, then scan a programming code in this manual, the scanner displays the content of a 
programming code.  The programming function will still occur, but in addition, the content of that programming code is output to 
the terminal.  
Note: This feature should not be used during normal scanner operation.
TotalFreedom
TotalFreedom is an open system architecture that makes it possible for you create applications that reside on your scanner.

EZConfig-Scanning Introduction
EZConfig-Scanning provides a wide range of PC-based programming functions that can be performed on a scanner connected 
to your PC.  EZConfig-Scanning allows you to download upgrades to the scanners firmware, change programmed parameters, 
and create and print programming bar codes.  Using EZConfig-Scanning, you can even save/open the programming parameters 
for a scanner.  This saved file can be e-mailed or, if required, you can create a single bar code that...

Resetting the Factory Defaults
If you aren’t sure what programming options are in your scanner, or you’ve changed some options and want to restore the scan-
ner to factory default settings, first scan the Remove Custom Defaults bar code, then scan Activate Defaults.  This resets the 
scanner to the factory default settings.
Note: If using a cordless system, scanning the Activate Defaults bar code also causes both the scanner and the base or Access 
Point to perform a reset and become unlinked....
