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.
Scanner and Accessories following is a list of the parts included in the MS6720 kit. MS6720 Hand-Held Laser Scanner - Refer to page 27 for available communication protocols Stand (MLPN 45967) - Refer to page 8 for available kits Optional Power Transformer 120V or 220V or 240V (AC in)
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.
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.
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.
6-pin mini DIN male on the other. Also included with the MS6720 is an adaptor cable with a 5-pin male DIN on one end and a 6-pin female mini DIN on the other to mate to a specific keyboard.
(also included is the wall mount clip). The instruc- tions for use of the wall mount clip are included with the general assembly instructions for the stand. Listed below are the component parts of the MS6720 stand kits. 1) Complete Stand Kit:...
When the green light turns off, communica- tion to the host is complete. The green LED blinks while the scanner is waking up from an IR sensor timeout. The LED’s are also used as diagnostic indicators and mode indicators.
Audible Indicators When the MS6720 scanner is in operation, it provides audible feedback. These sounds indicate the status of the scan and scanner. Four settings are available for the tone of the beep. To change the tone, refer to the Program- ming Guide section: Beeper Tones.
Return the unit for repair at an authorized service center. Three Beeps - on power up If the scanner beeps 3 times on power up then, the non volatile memory which holds the scanner configuration has failed. Return the unit for repair at an authorized service...
Visual Indicators There are a red LED and a green LED on the scanner. When the scanner is on, the flashing or stationary activity of the LEDs indicates the status of the scan and scan-ner. No Red or Green LED There are two reasons why the LEDs will not be illuminated: 1.) If the scanner is receiving power and the LEDs are not on, then...
Label Each scanner has a label located on the bottom of the unit. This label contains information such as the model number, date of manufacture, serial number, and approvals. This label also notes that the device is a CDRH Class IIa laser product. The following is an example of this label:...
Automatic Turn-On Specifications (IR Sensor) Normal Depth of Field Short Depth of Field Note: Depth of Field based on 13mil (.013") minimum element width, Turn On Range is nominal; small variances do NOT indicate a malfunction.
Scan Pattern Specifics Projection Axis The scan pattern of the MS6720 exits straight out of the scanner. This feature was purposefully designed to provide pointing efficiency in the hand held mode and instinctive positioning in the fixed presentation mode. Omnidirectional Scan Volume Note: The above scan volume shows omnidirectional volume.
Maintenance Smudges and dirt can interfere with the proper scanning of a bar code. Therefore, the output window will need occasional cleaning. 1. Spray glass cleaner onto lint free, non-abrasive cleaning cloth. 2. Gently wipe the scanner window.
Check transformer, outlet and power or motor spin strip NOTE: If it’s a direct connect scanner, the problem could be inadequate power being supplied to the scanner. It may be necessary to use a Metrologic transformer for power. Check the fuse in the MCA.

The unit powers up properly, lasers come on, but the unit does not scan and does not beep when a bar code is presented POSSIBLE CAUSE(S)/SOLUTION(S) Improper settings can be the cause for a scanner not to scan. The following would be typical examples: 1. Scanning a particular symbology that is not enabled. (UPC/EAN, Code 39, Interleaved 2 of 5, Code 93, Code 128 and Codabar are enabled by default.)

This program is for demonstration purposes only. It is only intended to prove that cabling is correct, the comx port is working, and the scanner is working. If the bar code data displays on the screen while using this program, it only demon-strates that the hardware interface and scanner are working.
Light Pen Emulation (LTPN) 6720 Keyboard Wedge (KBW) The MS6720 Hand-Held Laser Scanner with Built-in PC Keyboard Wedge Interface is designed to be used for keyboard emulation only. However, many RS-232 programmable functions that are available in other Metrologic scanners are also available as keyboard wedge functions.

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.

+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.
Pin Assignments for the 5-pin DIN and 6-pin mini-DIN MS6720 Hand- Held Laser Scanner with Built-in PC Keyboard Wedge Interface The coil cable is terminated with a 5-pin DIN female connector on one end, and a 6-pin mini DIN male on the other. Metrologic will supply an adaptor cable with a 5-pin DIN male connector on one end and a 6-pin mini DIN female connector on the other.
