Connecting with Keyboard Wedge
A scanner can be connected between the keyboard and PC as a “keyboard wedge,” 
where the scanner provides data output that is similar to keyboard entries. The 
following is an example of a keyboard wedge connection:
1. Turn Off power and disconnect the keyboard cable from the back of the 
terminal/computer.
2. Connect the appropriate interface cable to the device and to the terminal/
computer.
3. Turn the terminal/computer power back On. The scanner beeps.
4. Verify the scanner operation by scanning a barcode from the Sample Symbols, 
beginning on page 220. The scanner beeps once.
The unit defaults to an IBM PC AT and compatibles keyboard wedge interface with 
a USA keyboard. A carriage return (CR) suffix is added to barcode data.
