Simply scan the correct bar code(s) from the FULL ASCII MENU. For
example, if the WDP reads the bar code SOH (ASCII 001 -- a control-A) from
the FULL ASCII MENU, it will transmit an F1 key.
Shift, Ctrl and Alt keys require three sequences:
1) The ON code generated when the Shift, Ctrl or Alt key is pressed.
2) The other key to be used in conjunction with the Shift, Ctrl or Alt key.
3) OFF code generated when the Shift, Ctrl or Alt key is released.
(For example, to create a Control C bar code: use Control ON, C, and Control
OFF. To put Control C in a Preamble or Postamble, scan from the Full ASCII
Menu: Control ON, C, and Control OFF).
Function keys F11 and F12
Function keys F11 and F12 require two bar codes to be scanned to make these
functions keys. The F11 key is created by combining the Null and SOH. The
F12 key is created by combining the Null and the STX.
Windows Key
The Windows key on a Windows keyboard is transmitted by scanning 4 bar
codes - NULL and C for Windows On (pressing down) and NULL and D for
Windows Off (releasing the key).
Command and Option Keys on Mac USB Keyboards
When you have a WDP Reader attached to a Macintosh Computer's USB port,
to emulate the Command key, use the Windows key ON/OFF bar codes
NULL, C (Command ON) and NULL, D (Command OFF) For the Option Key
ON/OFF use RS (Option On) and US (Option Off).
Transmitting any ASCII character using its 3-digit ASCII code
You can also transmit any ASCII character from 000 to 255 by emulating the
PC technique of typing a character's ASCII number on the numeric pad while
holding down the Alt key. For example, to transmit ASCII 250, you would
scan the bar codes for:
Keystroke
Full ASCII Menu
Bar Code
Alt ON RS
Ins (0 on the numeric pad) DC2
Down Arrow (2 on the numeric pad) NAK
Numpad 5 LF
Ins (0 on the numeric pad DC2
Alt OFF US
