Scanner Installation
To maintain compliance with applicable standards, all circuits con-
nected to the scanner must meet the requirements for SELV (Safety
Extra Low Voltage) according to EN 60950. To avoid potential prob-
lems, 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.
Note: The following statement is applicable if the optional
power adapter available through Metrologic does not power
the bar code scanner and the scanner receives power from a
host device such as a computer system.
Caution: To maintain compliance with standards CSA
C22.2 No. 950/UL 1950 and norm EN 60950, the
power source must meet applicable performance
requirements for a limited power source.
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. A socket-outlet must be installed near the
equipment and be easily accessible. Plug the transformer into
the AC outlet to supply power to the scanner.
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.
