INSTALLING THE SCANNER TO THE HOST SYSTEM
STAND ALONE KEYBOARD
1. Turn off the host system.
2. Connect the 10-pin RJ45 male
connector into the jack on the
Voyager or VoyagerCG. You will
hear a ‘click’ when the connection is
made.
If the scanner is receiving
power from the host system,
skip to step #5.
3. Connect the L-shaped plug of the
power supply into the power jack on
the PowerLink cable.
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. Connect the PowerLink cable to the
keyboard port on the host system.
6. Turn on the host system.
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 would 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 connected to the scanner must
meet the requirements for SELV (Safety Extra Low Voltage) according to EN 60950.
To maintain compliance with standard CSA C22.2 No. 950/UL 1950 and norm EN 60950, the
power source should meet applicable performance requirements for a limited power source.
