Scanner Installation
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 avoid potential problems, do not power up the
scanner until the communication cable is secured to the host.
1. "Power off" the host system.
2. Locate the 19-pin female end of the scanner link cable and find the
widest key located above pins L and A. Align this key with the
corresponding key on the scanner box’s Mil spec connector. While
pushing in on the connector, rotate the ring clockwise until it locks into
place with a click.
3. Connect the other end of the communication cable to the host device. (If
the scanner is powered by the host, skip to Step 5.)
4. Check the AC input requirements of the transformer/power supply to
make sure the voltage matches an available AC outlet. Plug the
transformer into the AC outlet to supply power to the scanner. (A
socket-outlet shall be installed near the equipment and shall be easily
accessible.)
5. "Power up" the host system.
Note: When the scanner first receives power, the LEDs will flash and
then the scanner will beep once. After the scanner performs this
startup sequence, the green LED will remain on for a specified
time indicating that the laser is on.
