NSTALLATION
Keyboard Wedge
1. Turn off the host device.
2. Plug the male 10-pin RJ45 end of the
PowerLink cable into the 10-pin
socket on the MS3580.
3. Disconnect the keyboard from the
host device.
4. Connect the “Y” end of the PowerLink
cable to the keyboard and the
keyboard port on the host PC. If
necessary use the male/female
adapter cable supplied with the
scanner for proper connections.
5. Plug the external power supply into the
power jack on the PowerLink cable.
Check the AC input requirements
of the power supply to make sure
the voltage matches the AC
outlet. The outlet must be
located near the equipment and
be easily accessible.
6. Connect AC power to the transformer.
7. Turn on the host device.
When the scanner first receives power, the blue LED will turn on; the
scanner will simultaneously emit a beep and flash the white LED.
Powering the MS3580 directly from the host device can sometimes
cause interference with the operation of the scanner or the computer.
Not all computers supply the same current through the keyboard port.
For this reason, Metrologic recommends using an external power
supply. For additional information contact a Metrologic customer
service representative.
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/IEC
60950.
To maintain compliance with standard CSA C22.2 No. 60950/UL 60950 and norm
EN/IEC 60950, the power source should meet applicable performance requirements for
a limited power source.
