Special Features

Function and Control Key Support

The WDP Reader 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.

When the WDP reader reads a Code 128 or Full-ASCII Code 39 (or the equivalent two-character Code 39 sequences) bar code containing one of the control characters in the table above, it transmits the appropriate key code(s) for the IBM or Mac computer interface.

Function keys F1 through F10, and numeric-pad keys

Function keys F1 through F10, and numeric-pad keys (such as Left Arrow and Del), are encoded by a single control character (or the equivalent two-character Code 39 sequences) as shown in the table above.

For example, if the WDP Reader reads bar code data of SOH (ASCII 001 -- a control-A), it will transmit an F1 key sequence to your computer.

Function keys F11 and F12

Function keys F11 and F12 require two characters to be paired to make these functions keys. The F11 key is created by combining the Null Character (%U in Code 39) and SOH ($A in Code 39). The F12 key is created by combining the Null Character (%U in Code 39) and the STX ($B in Code 39).
