INSTALLATION
Stand-Alone Keyboard
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. Connect the other end of the
PowerLink cable to the keyboard
port on the host device.
4. 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.
5. Connect AC power to the transformer.
6. 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.
