  • Page 5: Introduction

    Introduction The MS6720 is the first laser bar code scanner truly to bridge the gap between omnidirectional fixed projection and hand-held scanners. It incorporates fixed projection performance and our patented 20-line scan pattern into a comfortable, ergonomic styling of our popular hand-helds. With this design, Metrologic has engineered a scanner that transcends any other on the market today.

    Both LEDs come on together along with the beep-the green LED only flashes. Note: Two methods that the scanner can be powered are as follows: External Power Supply or Host Device ie the PC for the MS6720 with a Built-in PC Keyboard Wedge interface.

  • Page 9: Scanner Installation: Powered By External Power Supply

    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. If using a communication cable, connect the cable to the correct port on the host device and the MCA (Metrologic Connector Adaptor).
