Wand Emulation
Wand Emulation Connection
The Wand Emulation Connection bar codes should be used if you want to 
change the terminal ID only, without changing any other image scanner set-
tings.  We recommend using Wand Emulation Plug & Play bar codes to pro-
gram your image scanner to emulate a wand reader.  The Wand Emulation Plug 
& Play bar codes change other parameters, in addition to changing the terminal 
ID.   Please refer to Wand Emulation Plug & Playon page 1-22 for further infor-
mation. 
In Wand Emulation mode, the image scanner decodes the bar code then sends 
data in the same format as a wand scanner.  The Code 39 Format converts all 
symbologies to Code 39.    
The Same Code Format transmits UPC, EAN, Code 128 and Interleaved 2 of 5 
without any changes, but converts all other symbologies to Code 39.  2D sym-
bologies are converted to Code 128.
The 
Code 39 Format bar code below sets the terminal ID to 61, and the Same 
Code Format bar code sets the terminal ID to 64.

Wand Emulation Transmission Rate
The transmission rate is limited by the terminal’s ability to receive data without 
dropping characters.  Default = 25 inches/second.
Wand Emulation Polarity
The Polarity can be sent as standard with black bars high, or reversed with 
white bars high.  Default = Black High.
Wand Emulation Idle
The idle describes the state of the image scanner when no data is being trans-
mitted.  When in Wand Emulation mode, you must set the image scanner’s idle 
state to match the idle state for the device to which the image scanner is con-
nected.  
Default = Idle High.

Wand Emulation Data Block Size
This transmits the data in smaller blocks to prevent buffer overflow.  Default =

.
Wand Emulation Delay Between Blocks
This sets the delay time between data blocks.  Default = 50ms.
Wand Emulation Overall Checksum
When this option is turned on, a computed check character is added at the end 
of the entire message.  The check character is the character which when Exclu-
sive-OR’d with every preceding character of the message yields a result of 0x00 
(00H).  
Default = Off.

Image Scanner Functions
Good Read Indicators
Beeper – Good Read
The beeper may be programmed On or Off in response to a good read.  Turning 
this option off, only turns off the beeper response to a good read indication.  All 
error and menu beeps are still audible.  
Default = On.
Beeper Volume – Good Read
The beeper volume codes modify the volume of the beep the image scanner 
emits on a good read.  Default = Medium.
* Beeper - Good Read On
 Beeper - Good Read Off
High* Medium

							3 - 2
Beeper Pitch – Good Read
The beeper pitch codes modify the pitch (frequency) of the beep the image 
scanner emits on a good read.  Default = Medium.
Beeper Duration – Good Read
The beeper duration codes modify the length of the beep the image scanner 
emits on a good read.  Default = Normal.
LED – Good Read
The LED indicator can be programmed On or Off in response to a good read.  Default = On.
Number of Beeps – Good Read
The number of beeps of a good read can be programmed from 1 - 9.  The same 
number of beeps will be applied to the beeper and LED in response to a good 
read.  For example, if you program this option to have five beeps, there will be 
five beeps and five LED flashes in response to a good read.  The beeps and LED 
flashes are in sync with one another.  To change the number of beeps, scan the 
bar code below and then scan a digit (1-9) bar code and the Save bar code on 
the Programming Chart inside the back cover of this manual.  
Default = One.

Good Read Delay
This sets the minimum amount of time before the image scanner can read 
another bar code.  Default = 0 ms (No Delay.)
User-Specified Good Read Delay
If you want to set your own length for the good read delay, scan the bar code 
below, then set the delay (from 0-30,000 milliseconds) by scanning digits from 
the inside back cover, then scanning 
Save. 
Image Scanner Trigger Modes
Manual/Serial Trigger, Low Power
You can activate the image scanner either by pressing the trigger, or using a 
serial trigger command (see Trigger Commandson page 10-4).  When in 
manual trigger mode, the image scanner scans until a bar code is read, or until 
the trigger is released. 
When in serial mode, the image scanner scans until a bar code has been read 
or until the deactivate command is sent.  In serial mode, the image scanner can 
also be set to turn itself off after a specified time has elapsed (see Read Time-
Out (Serial Trigger Mode), which follows).

Read Time-Out (Serial Trigger Mode)
Use this selection to set a time-out (in milliseconds) of the image scanner’s 
trigger when using serial commands to trigger the image scanner.  Once the 
image scanner has timed out, you can activate the image scanner either by 
pressing the trigger or using a serial trigger command.  After scanning the Read 
Time-Out bar code, set the time-out duration (from 0-300,000 milliseconds) by 
scanning digits on the Programming Chart inside the back cover, then scanning 
Save.  
Default = 30,000 ms.
Image Scanner Power Time-Out Timer
Note: The Image Scanner Power Time-out Timer option only applies to Manual/
Serial Trigger.
When there is no activity within a specified time period, the image scanner enters 
low power mode.  Scan the appropriate Image Scanner Power Time-Out bar 
code to change the time-out duration (in seconds).
Note:  Scanning zero (0) is the equivalent of setting no time-out.
Read Time-Out 
						

							3 - 5
If there are no trigger pulls during the “image scanner power time-out timer” 
interval, the image scanner goes into power down mode.  Whenever the trigger 
is enabled, the “image scanner power time-out timer” is reset.  If the image 
scanner is placed in the 2020 cradle and the battery is in the process of being 
charged, the image scanner will not go into power down mode.
Note: When the image scanner is in power down mode, pull the trigger to power 
the unit back up.  There will be a set of power up beeps and a delay of up 
to a few seconds for the radio to join.  The image scanner will then be 
ready to use.
Automatic Trigger
The image scanner scans continuously at full power with illumination fully on.
Presentation Mode
The LEDs are off until a bar code is presented to the image scanner.  Then the 
LEDs turn on automatically to read the code.  Presentation Mode uses ambient 
light to detect the bar codes.  If the light level in the room is not high enough, 
Presentation Mode will not work properly.

Hands Free Time-Out
The Automatic Trigger and Presentation Modes are referred to as “hands free” 
modes.  If the image scanner’s trigger is pulled when using a hands free mode, 
the image scanner changes to manual trigger mode.  You can set the time the 
image scanner should remain in manual trigger mode by setting the Hands Free 
Time-Out.  Once the time-out value is reached, (if there have been no further 
trigger pulls) the image 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 image 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 at 
POS (point of sale).  Use shorter delays in applications where repetitive bar code 
scanning is required.  
Default = Medium.
Reread Delay only works when in automatic trigger mode (see page 3-5).
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 milliseconds) by scanning digits from the 
inside back cover, then scanning 
Save.
