Scanner Installation: Powered by External Power Supply
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.
1. Turn off the host system.
2. Make the necessary PowerLink cable connections to the scanner and
the host.
3. Connect the external transformer into the power jack on the Power Link
cable.
4. Check the AC input requirements of the power supply to make sure the
voltage matches the AC outlet. (the socket-outlet shall be installed near
the equipment and shall be easily accessible.) Connect AC power to the
transformer.
5. Turn on the host system .
NOTE:
a. When the scanner first receives power, the red LED will turn
on. Then the scanner will beep once and the green LED will
flash simultaneously.
b. Plugging the scanner into the serial port of the PC does not
guarantee that scanned information will appear at the PC. A
software driver and correct configuration setting are also
required for proper communication to occur.
