I NSTALLING THE IS6520-47/MS6520-47 TO THE PC
1. Turn off the PC.
2. Connect the 10-pin RJ45 male connector into the jack on the Cubit™
IS6520/MS6520. You will hear a ‘click’ when the connection is made.
3. Connect the L-shaped plug of the power supply into the power jack on the
PowerLink cable. Refer to Manufacturer’s Recommendation below.
4. Connect the power supply into an AC outlet. Make sure the AC input
requirements of the power supply match the AC outlet.
5. Disconnect the keyboard from the PC.
6. The PowerLink 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 31 for pin
assignments.
7. Connect to the PowerLink cable to the keyboard and the keyboard port on
the PC.
8. Power up the PC.
Manufacturer’s Recommendation:
Metrologic recommends the use of an external power supply with IS6520-
47/MS6520 Keyboard Wedge applications. Powering the IS6520-47/MS6520
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, explaining why a scanner would work on one
computer and not another.
Caution:
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.
