1 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.
2 Scanner and Accessories The 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.
3 Quick Start 1.) Plug in the scanner. Both LEDs come on together along with the beep-the green LED only flashes. 2.) The scanner is shipped from the factory programmed with default settings.
4 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: 1. Plug one end of the coil cable into the keyboard connector on the PC. Then plug the keyboard connector into the other end of the coil cable.
5 MCA Female 9-pin D 10 Position Modular Connector at the end of the Coil Cable 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 ( S afety E xtra L ow V oltage) according to EN 60950.
6 MCA Female 9-pin D MCA MS6720 coil cable MCA host Scanner Installation: Powered by Host Device If the host system supplies +5VDC power to the scanner, reposition the internal jumper within the MCA ( M etrologic C onnector A daptor) before connecting the scanner to the host device.
7 MS6720 » » “Y” coil cable º º PC Scanner Installation to the PC for the Scanner with Built-in PC Keyboard Wedge Interface To maintain compliance with applicable standards, all circuits connected to the scanner must meet the requirements for SELV ( S afety E xtra L ow V oltage) according to EN 60950.
8 The MS6720 Stand The stand for the MS6720 is ergonomic and application friendly. The mounting was designed to provide an adequate distance for scanning between the scanner face and the counter top at all times. When fully tilted, the face of the scanner remains a full five inches from the counter.
Green and Red LED When the red LED is on, this indicates that the laser is on. When the green LED flashes on, the scanner has read a bar code successfully. 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.
10 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.
11 Failure Modes Flashing Red and One Razzberry Tone This indicates the scanner has experienced a laser subsystem failure. Return the unit for repair at an authorized service center. Flashing Red and Green and Two Razzberry Tones This indicates the scanner has experienced a motor failure.
12 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.
13 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.
14 Depth of Field Specifications Normal Depth of Field.
15 Short Depth of Field.
16 Extended Depth of Field.
17 Optional Depth of Field.
18 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.
19 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.
20 Cross-Sectional Scan Pattern.
21 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.

23 All Interfaces continued SYMPTOMS POSSIBLE CAUSE(S) SOLUTION Unit goes to IR sensor used to wake up Adjust scanner positioning so that the sleep and does the scanner is always IR senses an object when a bar code not wake up sensing an object is presented.
24 SYMPTOMS 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.
25 Keyboard Wedge Only SYMPTOMS POSSIBLE CAUSE(S) SOLUTION Unit scans the Configuration is not correct Make sure the scanner is configured bar code but for keyboard wedge mode - Section there is no da.
26 RS-232 only SYMPTOMS POSSIBLE CAUSE(S) SOLUTION Power-up OK Com port at the host not Check to make sure the baud rate Scans OK properly communication port match and the Does not Cable not connected to the data.
27 Applications and Protocols The model number on each scanner includes the scanner number and communications protocol. Scanner Version Identifier Communication Protocol(s) 6720 9 OCIA (OCIA) 6720 11 .

34 Appendix C 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.
35 Pin Assignments for the MCA951 (DEC9S) Located on the MCA is a 9-pin female D-type connector used to connect the MCA to the host device. The output signals on the 9-pin host end of the MCA are dependent upon which version of the scanner that is being used.
