INSTALLING THE SCANNER TO THE HOST SYSTEM
KEYBOARD WEDGE MS9520-47 AND MS9540-47
1. Turn off the PC.
2. Connect the 10-pin RJ45 male
connector into the jack on the
Voyager or the VoyagerCG. 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.
If the scanner is receiving
power from the host system,
skip to step #5.
4. Make sure the AC input
requirements of the power supply
match the AC outlet. Connect the
power supply into an AC outlet.
The outlet should be near the
equipment and easily accessible.
5. Disconnect the keyboard from the
PC.
6. Connect the PowerLink cable to the
keyboard and the PC’s keyboard port.
If necessary use the supplied adapter
cable (5-pin male DIN to 6-pin female
mini DIN adapter).
7. Power up the PC.
Powering the MS9520-47/MS9540-47 directly from the computer can
sometimes cause interference with the operation of the scanner or the
computer. Not all computers supply the same current through the
keyboard port, explaining why a scanner may work on one computer
and not another. Contact a Metrologic Customer Service
Representative if you require an external power supply.
Caution:
To maintain compliance with applicable standards, all circuits con nected to the scanner must
meet the requirements for SELV (Safety Extra Low Voltage) acc ording to EN 60950.
To maintain compliance with standard CSA C22.2 No. 950/UL 1 950 and norm EN 60950, the
power source should meet applicable performance requirement s for a limited power source.
