  • Page 4: 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.

    Note: Any time the Load Defaults bar code is scanned the MS6720 is configured for an RS-232 interface. If a RS-232 is not being used, scan at least one other bar code to enable Keyboard Wedge, OCIA, Light Pen or 46xx.

  • Page 7: Operational Test

    Operational Test If the scanner is to receive power from an external power supply, test the scanner before it is connected to the host system. Keyboard Wedge Scanners: Plug one end of the coil cable into the keyboard connector on the PC.

    When the scanner first receives power, both LEDs come on together along with the beep-the green LED only flashes. b. Plugging the scanner into the serial port of the PC does not guarantee that scanned information will appear at the PC. A software driver and correct configuration setting are also required for proper communication to occur.

  • Page 9: Scanner Installation: Powered By The Host Device

    Scanner Installation: Powered by Host Device If the host system supplies +5VDC power to the scanner, reposition the internal jumper within the MCA (Metrologic Connector Adaptor) before connecting the scanner to the host device. In addition, plug the 4 position ground jumper into the power supply connector located on the side of the MCA.

  • Page 37: Pin Assignments

    Cable Pin Assignments for the Coil Cable The MS6720 scanners are terminated to a 10 position shielded modular connector. All of the coil cables (MLPN 44530) for the MS6720 scanner are terminated the same. The difference between versions is the end of the cable going into the scanner.
  • Page 38 +5VDC Power to Scanner +5VDC Power to Scanner *When the host supplies power to the scanner, this is the pin assignment for the +5VDC for the scanner. If, in the application, the host device will supply the power necessary for the scanner, reposition an internal jumper within the MCA and plug the 4 position ground jumper to the power supply connector for FCC and ESD purposes.
