Scanner Installation to the PC for the Scanner with Built-in PC Keyboard Wedge Interface

To maintain compliance with applicable standards, all circuits connected to the scanner must meet the requirements for SELV (Safety Extra Low Voltage) according to EN 60950.

1.The MS7120 Keyboard Wedge scanner interface terminates to a 10-pin modular jack. Connect the 10-pin modular plug of the PowerLink cable into the jack. The Power Link cable is terminated with a 5-pin DIN female connector on one end, and a 6-pin mini DIN male on the other. Metrologic will supply an adapter cable with a 5-pin DIN male connector on one end and a 6-pin mini DIN female connector on the other. According to the termination required, connect the appropriate end of the adapter cable to the PowerLink cable, leaving the necessary termination exposed for connecting to the keyboard and the keyboard port on the PC. Refer to Appendix C page 38 for pin assignments.

2.If the PC is on, exit the application and turn the PC off.

3.Disconnect the keyboard from the PC.

4.Connect the scanner as described in step 1. Connect the external transformer into the power jack on the Power Link cable. Refer to Manufacturer’s Recommendation below. Connect AC power to the transformer.

5.Power up the PC.

Manufacturer’s Recommendation:

Metrologic recommends the use of an external power supply with MS7120-47 Keyboard Wedge applications. Powering the MS7120-47 directly from the com- puter keyboard connector could interfere with the operation of the scanner or the computer. Not all computers supply the same current through the keyboard port, this explains why a scanner would work on one computer and not another.
