4.11 Keyboard Layouts and Delimiters

A delimiter is the unique keycode generated by a particular terminal key

whenever it is depressed. Every key on the keyboard is assigned its own

code. The terminal uses these codes to identify the key that was depressed,

and the function that key represents.

The SCANTEAM 2380 can be programmed to recognize these function

keycodes as field delimiters. When field delimiters are used to separate bar

code data, the terminal interprets the data codes produced by scanning a bar

code symbol(s) as originating from the keyboard without the function key

being depressed.

Delimiters for a particular terminal can be determined by referring to the

keyboard layouts provided on the Keyboard Layouts page of the

programming menu. Refer to Figure 4.3 for an example of the keyboard

layout for an NCR 7052/32 and 56 key terminal.

Note that certain keys are marked with a number and letter. These

designations (i.e., the A1, A5, C3 etc.) are the delimiters associated with

that particular function key.

Once the delimiters have been programmed, the SCANTEAM 2380

automatically generates the proper keycode and sends it to the terminal just

as though the terminal function key had been depressed.
