INSTALLATION
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 IS3480.
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.
Powering the IS3480 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, al l circuits connected to the scanner
must meet the requirements for SELV (Safety Extra Low Voltag e) 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 applic able performance requirements for
a limited power source.
