Scanner Connections
In order for the scanner 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. Turn off the host system.
2. Find the 19-pin female end of the scanner link cable and 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.
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 will not receive power from a transformer, skip to Step 6.
4. If the scanner will receive power from an external power source, check the AC input
requirements of the transformer to make sure the voltage matches the AC outlet.
(A socket-outlet should be installed near the equipment and must be easily accessible.)
5. Plug the transformer into the AC outlet to supply power to the scanner.
6. Power up the host system.
7. Scan a few items to verify that data is being properly transmitted between the scanner
and the host device.
