Connecting the Scanner When Powered by Host
(K eyboard Wedge)
A scanner can be connected between the keyboard and PC as a “keyboard
wedge,” plugged into the serial port, or connected to a portable data terminal in
wand emulation or non decoded output mode. The following is an example of a
keyboard wedge connection:
1. Turn off power to the terminal/computer.
2. Disconnect the keyboard cable from the back of the terminal/computer,
as shown below.

4. Turn the terminal/computer power back on. The scanner will beep
twice.
5. Verify the scanner operation by scanning a bar code from the back
cover of this manual. The scanner will beep once.
The scanner is now connected and ready to communicate with your
terminal/PC. You must program the scanner for your interface before bar code
data can be transmitted to your terminal/PC. If you are using the scanner as a
keyboard wedge, turn to page 2–1. If the scanner is connected via a serial
port, turn to page 2–8. If this is a wand emulation application, turn to page
2–13, and for a non decoded output connection, turn to page 6–2.
