Product Reference Guide

        

Control character emulation selects from different scancode tables as 

listed in this appendix. Each of the control character sets below are 

detailed by interface type in the tables. These apply to Wedge and USB 

Keyboard platforms.

Characters from 00 to 0x1F are sent as control 

character Ctrl+Keys, special keys are located from 0x80 to 0xA1.

Characters from 00 to 0x1F are sent as control 

character Ctrl+Capital Key, special keys are located from 0x80 to 0xA1.

Special keys are located from 00 to 0x1F and 

characters from 0x80 to 0xFE are intended as an extended ASCII table 

(Microsoft Windows Codepage 1252 — see 

).

In the following tables, Ar

↓

 means Alt right pressed and Ar

↑

 

means Alt 

right released and so on. Definitions for other keys are Al (Alt left ), Cr 

(Control Right ) Cl (Control Left ) Sh (shift). This method can be used for 

combining Alt, Control or Shift with other keys.
Example: Consider a Control character set to 00. If AltRight+A is 

required before sending a label to the host, it could be done by setting 

three Prefix keys in this way: 0x99 0x41 0x9A.
