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.
Parameter Label
Key Type / Status Label
Two Hexadecimal Labels
"Validate" Label
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.
10.4.3Key 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
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”
Note: 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.
10.5Exit Configuration Mode
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.
