Centering Window
Use the centering feature to narrow the image scanner’s field of view so the 
image scanner reads only the bar code you want.  When centering is turned on, 
the image scanner only reads codes that intersect or are contained within the 
centering window you set up.  At least part of a bar code must be within the 
window to be decoded or output by the image scanner.
To change the left or right edge of the centering window, scan Centering On, 
then scan one of the following bar codes....

3 - 8
Example:If you have two bar codes next to one another and the centering 
window is set to 40% left edge and 60% right edge, only the bar 
code that intersects that window will be decoded.
Preferred Symbology
The 3820/3820i can be programmed to specify one symbology as a higher 
priority over other symbologies in situations where both bar code symbologies 
appear on the same label, but the lower priority symbology cannot be disabled.
For example, you may be using the imager in a retail setting to...

3 - 9
High Priority Symbology
To specify the high priority symbology, scan the High Priority Symbology bar 
code below.  On the Symbology Charton page A-1, find the symbology you want 
to set as high priority.  Locate the Hex value for that symbology and scan the 2 
digit hex value from the Programming Chart (inside back cover).  Scan Save to 
save your selection.  
Default = None
Low Priority Symbology
To specify the low priority symbology, scan the Low Priority Symbology bar code 
below.  On the...

Output Sequence Overview
Require Output Sequence
When turned off, the bar code data will be output to the host as the image 
scanner decodes it.  When turned on, all output data must conform to an edited 
sequence or the image scanner will not transmit the output data to the host 
device.
Note: This selection is unavailable when the Multiple Symbols Selection is 
turned on.
Output Sequence Editor
This programming selection allows you to program the image scanner to output 
data (when scanning more...

5.End Output Sequence Editor
Scan F F to enter an Output Sequence for an additional symbology, or Save to save your entries.
Other Programming Selections
Discard This exits without saving any Output Sequence changes.
Output Sequence Editor   
Require Output Sequence
When an output sequence is Required, all output data must conform to an edited 
sequence or the image scanner will not transmit the output data to the host 
device.  When it’s 
On/Not Required, the image scanner will attempt to get the...

Output Sequence Example
In this example, you are scanning Code 93, Code 128, and Code 39 bar codes, 
but you want the image scanner to output Code 39 1st, Code 128 2nd, and Code 
93 3rd, as shown below.
Note: Code 93 must be enabled to use this example.
You would set up the sequence editor with the following command line:
SEQBLK62999941FF6A999942FF69999943FF
The breakdown of the command line is shown below:
SEQBLKsequence editor start command
62 code identifier for Code 39
9999 code length that...

3 - 13
To program the previous example using specific lengths, you would have to 
count any programmed prefixes, suffixes, or formatted characters as part of the 
length.  If you use the example on page 3-12, but assume a  suffix and 
specific code lengths, you would use the following command line:
SEQBLK62001241FF6A001342FF69001243FF
The breakdown of the command line is shown below:
SEQBLK sequence editor start command
62 code identifier for Code 39
0012 A - Code 39 sample length (11) plus CR suffix (1)...

3 - 14
No Read
With No Read turned On, the image scanner sends an “NR” to the host if you 
pull and release the trigger without reading a code (e.g., bad bar code).  If No 
Read is turned 
Off, the “NR” will not be sent to the host.
If you want a different notation than “NR,” for example, “Error,” or “Bad Code,” 
you can edit the output message using the Data Formatter (page 5-4).  The hex 
code for the No Read symbol is 9C.  
Video Reverse
Video Reverse is used to allow the image scanner to read bar...

Data Editing
Prefix/Suffix Overview
When a bar code is scanned, additional information is sent to the host computer 
along with the bar code data.  This group of bar code data and additional, 
user-defined data is called a “message string.”  The selections in this section 
are used to build the user-defined data into the message string.
Prefix and Suffix characters are data characters that can be sent before and 
after scanned data.  You can specify if they should be sent with all symbologies,...

Step 4.Determine the hex value from the ASCII Conversion Chart (Code Page 
1252)on page A-4, for the prefix or suffix you wish to enter. 
Step 5.Scan the 2 digit hex value from the Programming Chart inside the back 
cover of this manual.
Step 6.Repeat Steps 4 and 5 for every prefix or suffix character.
Step 7.To add the Code I.D., scan 5, C, 8, 0.
 To add AIM I.D., scan 5, C, 8, 1.
 To add a backslash (\), scan 5, C, 5, C.
Note: To add a backslash (\) as in Step 7, you must scan 5C twice – once to...
