Scanner Connections to the Host

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.Connect the 25-pin D-type connector on the scanner’s head cable to the communication cable. Connect the other end of the communication cable to the host device. (If the scanner will not receive power from a transformer, skip to Step 5.)

3.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 can be installed near the equipment so it will be easily accessible.)

4.Plug the transformer into the side of the female D-type connector located on the communication cable. 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.
