used. These parameters are: Prefix Code, Postfix Code, Code ID, and Additional 
Fields of Editing Formats.  

The available key type/status settings can be selected will be described briefly. The 
configuration procedures for character string parameters are shown below. 

 

For example, to configure the Prefix Code to be “AB”, the “Prefix Code” label is 
first read, and then the hexadecimal digit labels “4”, “1”, “4”, and “2” are read, and 
finally, the “Validate” label to complete the setting. 

10.4.3  Key Type/Status Setting 
The key type/status is specified in character basis. Each character programmed is 
by default of Normal key type. A character of normal key type can have associate 
status settings (add Shift/Control/Alternate).  
Whereas a character of Scan Code type may not have any associate key status 
settings. 

•  Normal Key Type: When this label is read, the scanner will assume the 

following hexadecimal digits are the ASCII code of the character being 
programmed. And it will also clear all the associate key status settings made 
to the current character. 

•  Scan Code: When this label is read, the scanner will assume the following 

hexadecimal digits are the scan code value of the character being 
programmed. 

•  Add Shift: The Shift key will be sent together with the character 

programmed.

•  Add Control (L): The left Control key will be sent together with the 

character programmed. 

•  Add Alternate (L): The left Alternate key will be sent together with the 

character programmed. 

•  Add Control (R): The right Control key will be sent together with the 

character programmed. 

•  Add Alternate (R): The right Alternate key will be sent together with the 

character programmed. 

For example, to program the Prefix Code to be “Ctrl-Shift-B”, “C”, the 
programming sequence should be:  

1) “Prefix Code” label  
2) “Add Control (L)” label 
3) “Add Shift” label 
4) “4” of the hexadecimal digit 
5) “2” of the hexadecimal digit 
6) “4” of the hexadecimal digit 
7) “3” of the hexadecimal digit 
8) “Validate” 

 In internal representation, characters that are specified with either scan code 

or associate key status, occupy two normal characters each. So the maximum 
number of characters can be configured for a string parameter will decrease, if 
these character specifications are used. 

 
Both the “Update”, and the “Exit Setup without Changes” labels will exit the 
scanner from configuration mode when they are read. These two labels differ in 
whether to keep the new settings on the scanner or not, as their names suggest. The 
scanner will respond with 6 beeps and restart itself, if either label is read.
