Function/Control Key Support

The RF Laser can also transmit key sequences for function, control, alt (command and option keys on Macs),

cursor and shift keys, for ease of use with the many software packages using these keys for menus or

commands. You can include these codes in other bar codes, or you can scan these “keystrokes” into your

Preamble or Postamble in order to add them to every scan from your reader. You must have Full ASCII Code

39 enabled on your reader (this is the default setting). Scan the corresponding bar code (or pairs of codes for

Pg Up, Pg Dn, Home, etc) from the Full ASCII menu to emulate the chosen key.

* refers to the keys on the Number pad on the far right side of a PC keyboard. To emulate any of the keys

above, scan the appropriate bar code from the FULL ASCII MENU. For example, to emulate the f5 key, scan

the ENQ bar code.

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.
