Hands Free Time-Out
The Scan Stand and Presentation Modes are referred to as “hands free” modes.  If the scanner’s trigger is pulled when using a 
hands free mode, the scanner changes to manual trigger mode.  You can set the time the scanner should remain in manual trig-
ger mode by setting the Hands Free Time-Out.  Once the time-out value is reached, (if there have been no further trigger pulls) 
the scanner reverts to the original hands free mode.  
Scan the Hands Free Time-Out bar code, then scan the time-out duration (from 0-300,000 milliseconds) from the inside back 
cover, and Save.   Default = 5,000 ms.
Reread Delay
This sets the time period before the scanner can read the same bar code a second time.  Setting a reread delay protects against 
accidental rereads of the same bar code.  Longer delays are effective in minimizing accidental rereads.  Use shorter delays in 
applications where repetitive bar code scanning is required.  Reread Delay only works when in a Presentation Mode (see page 
4-7).  Default = Medium.  
User-Specified Reread Delay
If you want to set your own length for the reread delay, scan the bar code below, then set the delay (from 0-30,000 millisec-
onds) by scanning digits from the inside back cover, then scanning Save.

2D Reread Delay
Sometimes 2D bar codes can take longer to read than other bar codes.  If you wish to set a separate Reread Delay for 2D 
bar codes, scan one of the programming codes that follows.  2D Reread Delay Off indicates that the time set for Reread 
Delay is used for both 1D and 2D bar codes. Default = 2D Reread Delay Off.
Character Activation Mode
You may use a character sent from the host to trigger the scanner to begin scanning.  When the activation character is received, 
the scanner continues scanning until either the Character Activation Timeout(page 4-15), the deactivation character is received 
(see Deactivation Character on page 4-16), or a bar code is transmitted.  Scan the following On bar code to use character acti-
vation, then use Activation Character (following) to select the character you will send from the host to start scanning.  Default = 
Off.

Activation Character
This sets the character used to trigger scanning when using Character Activation Mode.  On the ASCII Conversion Chart 
(Code Page 1252), page A-3, find the hex value that represents the character you want to use to trigger scanning.  Scan 
the following bar code, then use the Programming Chart to read the alphanumeric combination that represents that ASCII 
character.  Scan Save to finish.  Default = 12 [DC2].
End Character Activation After Good Read
After a bar code is successfully detected and read from the scanner, the illumination can be programmed either to remain 
on and scanning, or to turn off.  When End Character Activation After Good Readis enabled, the illumination turns off 
and stops scanning after a good read.  If you scan Do Not End Character Activation After Good Read, the illumination 
remains on after a good read.  Default = Do Not End Character Activation After Good Read.
Character Activation Timeout
You can set a timeout for the length of time the illumination remains on and attempting to decode bar codes when using 
Character Activation Mode.  Set the length (in milliseconds) for a timeout by scanning the following bar code, then setting 
the timeout (from 1-300,000 milliseconds) by scanning digits from the Programming Chart inside the back cover of this 
manual, then scanning Save.  Default = 30,000 ms.
Character Deactivation Mode
If you have sent a character from the host to trigger the scanner to begin scanning, you can also send a deactivation character 
to stop scanning.  Scan the following On bar code to use character deactivation, then use Deactivation Character (following) to 
select the character you will send from the host to terminate scanning.  Default = Off.

Deactivation Character
This sets the character used to terminate scanning when using Character Deactivation Mode.  On the ASCII Conversion 
Chart (Code Page 1252), page A-3, find the hex value that represents the character you want to use to terminate scanning.  
Scan the following bar code, then use the Programming Chart inside the back cover of this manual to read the alphanu-
meric combination that represents that ASCII character.  Scan Save to finish.  Default = 14 [DC4].
Illumination Lights
If you want the illumination lights on while reading a bar code, scan the Lights On bar code, below.  However, if you want to turn 
just the lights off, scan the Lights Off bar code.  Default = Lights On.
Note: This setting does not affect the aimer light.  The aiming light can be set using Aimer Mode (page 4-17).   
Aimer Delay
The aimer delay allows a delay time for the operator to aim the scanner before the picture is taken.  Use these codes to set the 
time between when the trigger is pulled and when the picture is taken.  During the delay time, the aiming light will appear, but 
the LEDs won’t turn on until the delay time is over.   Default = Off.

User-Specified Aimer Delay
If you want to set your own length for the duration of the delay, scan the bar code below, then set the time-out by scanning 
digits (0 - 4,000 ms) from the Programming Chart inside the back cover of this manual, then scan Save.
Aimer Mode
This feature allows you to turn the aimer on and off.  When the Interlaced bar code is scanned, the aimer is interlaced with the 
illumination LEDs.  Default = Interlaced
Note: Granit 1980i and 1981i do not support Aimer Mode.
Centering
Use Centering to narrow the scanner’s field of view to make sure that when the scanner is hand-held, it reads only those bar 
codes intended by the user.  For instance, if multiple codes are placed closely together, centering will insure that only the 
desired codes are read.  (Centering  can be used in conjunction with Aimer Delay, page 4-16, for the most error-free operation 
in applications where multiple codes are spaced closely together.  Using the Aimer Delay and Centering features, the scanner 
can emulate the operation of older systems, such as linear laser bar code scanners.)
Note: To adjust centering when the scanner is in the stand, see Presentation Centering(page 4-9).
If a bar code is not touched by a predefined window, it will not be decoded or output by the scanner.  If centering is turned on by 
scanning Centering On, the scanner only reads codes that pass through the centering window you specify using the To p  o f  
Centering Window, Bottom of Centering Window, Left, and Right of Centering Window bar codes.

In the example below, the white box is the centering window.  The centering window has been set to 20% left, 30% right, 8% top, 
and 25% bottom.  Since Bar Code 1 passes through the centering window, it will be read.  Bar Code 2 does not pass through 
the centering window, so it will not be read.
Note: A bar code needs only to be touched by the centering window in order to be read.  It does not need to pass completely 
through the centering window.
Scan Centering On, then scan one of the following bar codes to change the top, bottom, left, or right of the centering window.  
Then scan the percent you want to shift the centering window using digits on the inside back cover of this manual.  Scan Save.   
Default Centering = 40% for Top and Left, 60% for Bottom and Right.

Preferred Symbology
The scanner 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 scanner in a retail setting to read U.P.C. symbols, but have occasional need to read a code 
on a drivers license.  Since some licenses have a Code 39 symbol as well as the PDF417 symbol, you can use Preferred Sym-
bology to specify that the PDF417 symbol be read instead of the Code 39.
Preferred Symbology classifies each symbology as high priority, low priority, or as an unspecified type.  When a low priority 
symbology is presented, the scanner ignores it for a set period of time (see Preferred Symbology Time-out on page 4-20) while 
it searches for the high priority symbology.  If a high priority symbology is located during this period, then that data is read imme-
diately. 
If the time-out period expires before a high priority symbology is read, the scanner will read any bar code in its view (low priority 
or unspecified).  If there is no bar code in the scanner’s view after the time-out period expires, then no data is reported.
Note: A low priority symbol must be centered on the aiming pattern to be read.
Scan a bar code below to enable or disable Preferred Symbology.    Default = Preferred Symbology Off.
High Priority Symbology
To specify the high priority symbology, scan the High Priority Symbology bar code below.  On the Symbology Chartson 
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 Symbology Chartson page 
A-1, find the symbology you want to set as low priority.  Locate the Hex value for that symbology and scan the 2 digit hex 
value from the Programming Chart (inside back cover).

If you want to set additional low priority symbologies, scan FF, then scan the 2 digit hex value from the Programming Chart 
for the next symbology.  You can program up to 5 low priority symbologies.  Scan Save to save your selection.  Default = 
None.
Preferred Symbology Time-out
Once you have enabled Preferred Symbology and entered the high and low priority symbologies, you must set the time-out 
period.  This is the period of time the scanner will search for a high priority bar code after a low priority bar code has been 
encountered.  Scan the bar code below, then set the delay (from 1-3,000 milliseconds) by scanning digits from the inside 
back cover, then scanning Save.  Default = 500 ms.
Preferred Symbology Default
Scan the bar code below to set all Preferred Symbology entries to their default values.
Output Sequence Overview
Output Sequence Editor
This programming selection allows you to program the scanner to output data (when scanning more than one symbol) in 
whatever order your application requires, regardless of the order in which the bar codes are scanned.  Reading the Default 
Sequence symbol programs the scanner to the Universal values, shown below.  These are the defaults.  Be certain you 
want to delete or clear all formats before you read the Default Sequence symbol.
Note: To make Output Sequence Editor selections, you’ll need to know the code I.D., code length, and character match(es) 
your application requires.  Use the Alphanumeric symbols (inside back cover) to read these options.  You must hold 
the trigger while reading each bar code in the sequence.
To Add an Output Sequence
1. Scan the Enter Sequence symbol (see Require Output Sequence, page 4-22).
2.Code I.D.
On the Symbology Chartson page A-1, find the symbology to which you want to apply the output sequence format.  
Locate the Hex value for that symbology and scan the 2 digit hex value from the Programming Chart (inside back 
cover).
3.Length
Specify what length (up to 9999 characters) of data output will be acceptable for this symbology.  Scan the four digit 
data length from the Programming Chart.  (Note:  50 characters is entered as 0050.  9999 is a universal number, 
indicating all lengths.)  When calculating the length, you must count any programmed prefixes, suffixes, or formatted 
characters as part of the length (unless using 9999).
4.Character Match Sequences
On the ASCII Conversion Chart (Code Page 1252), page A-3, find the Hex value that represents the character(s) you 
want to match.  Use the Programming Chart to read the alphanumeric combination that represents the ASCII 
characters.  (99 is the Universal number, indicating all characters.)

Output Sequence Example
In this example, you are scanning Code 93, Code 128, and Code 39 bar codes, but you want the 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:
SEQBLK sequence editor start command
62 code identifier for Code 39
9999 code length that must match for Code 39, 9999 = all lengths
41 start character match for Code 39, 41h = “A”
FF termination string for first code
6A code identifier for Code 128
9999 code length that must match for Code 128, 9999 = all lengths
42 start character match for Code 128, 42h = “B”
FF termination string for second code
69 code identifier for Code 93
9999 code length that must match for Code 93, 9999 = all lengths
43 start character match for Code 93, 43h = “C”
FF termination string for third code
To program the previous example using specific lengths, you would have to count any programmed prefixes, suffixes, or for-
matted characters as part of the length.  If you use the example on page 4-21, 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) = 12
A - Code 39
B - Code 128
C - Code 93

0013 B - Code 128 sample length (12) plus CR suffix (1) = 13
42 start character match for Code 128, 42h = “B”
FF termination string for second code
69 code identifier for Code 93
0012 C - Code 93 sample length (11) plus CR suffix (1) = 12
43 start character match for Code 93, 43h = “C”

Partial Sequence
If an output sequence operation is terminated before all your output sequence criteria are met, the bar code data acquired 
to that point is a “partial sequence.”  
Scan Discard Partial Sequence to discard partial sequences  when the output sequence operation is terminated before 
completion.  Scan Transmit Partial Sequence to transmit partial sequences.  (Any fields in the sequence where no data 
match occurred will be skipped in the output.)
Require Output Sequence
When an output sequence is Required, all output data must conform to an edited sequence or the scanner will not transmit 
the output data to the host device.  When it’s On/Not Required, the scanner will attempt to get the output data to conform 
to an edited sequence but, if it cannot, the scanner transmits all output data to the host device as is.
