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 “Y” coil cable is terminated with a 5-pin DIN female connector on one end, and a 6-pin mini DIN male on the other. Also included with the MS6720 is an adaptor cable with a 5-pin male DIN on one end and a 6-pin female mini DIN on the other to mate to a specific keyboard. According to the termination required, connect the appro- priate end of the adaptor cable to the coil cable, leaving the neces- sary termination exposed for connecting to the keyboard and the keyboard port on the PC. Refer to Appendix C page 36 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.Plug one end of the coil cable into the keyboard connector on the PC. Then plug the keyboard connector into the other end of the coil cable. Plug in the external transformer. Refer to Manufacturer’s Recommendation below. Connect AC power to the transformer.

Manufacturer’s Recommendation:
Metrologic recommends the use of an external power supply with MS6720-47 Key- board Wedge applications. Powering the MS6720-47 directly from the computer 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.
