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.
The MS6720 utilizes a unique, patented infrared sensor and control scheme
for hands-free projection scanning and fatigue reduced hand-held operation.
Whether operators choose to present small items to the scanner or transport
the lightweight scanner to bulkier items, the compact size and comprehen-sive
scan pattern make the MS6720 the perfect choice for many applica-tions.
The superior performance and features the world has come to expect from
Metrologic were packaged into the comfortable case only after tests and
approvals by hands of all sizes. With 84 degrees rotation and 10 locking
positions through 45 degrees of tilt, the stand for the MS6720 is also ergonomically and application friendly. 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 unit remains a full five inches from
the counter. In addition, the modular construction thoughtfully includes a
removable wall mount cap.
As with all Metrologic hand-held scanners, the MS6720 features both shortrange and long-range activation, user-friendly programming, reliability and
versatility. Operators are sure to appreciate the convenience and flexibility of
the MS6720, offered at an unbeatable price.

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.
To configure the MS6720 scanner to
meet the host system’s specific needs,
refer to the Programming Guide
(MLPN 2186) for instructions on how
to enter the program mode and to
select the appropriate bar codes.
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. Refer to sections B and F
in the ScanSelect Programming Guide (MLPN 2186).

MS6720 »» “Y” coil cable ºº PC
Manufacturer’s Recommendation:
Metrologic recommends the use of an external power supply with MS6720-47 Keyboard Wedge applications. Powering the MS6720-47 directly from the computer
keyboard connector could interfere with the operation of the scanner or the computer.
Not all computers supply the same current through the keyboard port, this explains why
a scanner would work on one computer and not another.

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. The stand comes preassembled so it can be attached to the
work surface with minimum effort (also included is the wall mount clip). The instructions 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.

Scanner Parts
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, communication 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.
Refer to pages 10-12 for details.
Coil Cable
This cable is terminated with a 10-pin modular connector, which attaches to
the MCA951. The Keyboard Wedge unit has a “Y” coil cable terminated with
a 5-pin female on one end, a 6-pin male and a 4-pin locking connector for
power input (power jumper). An adaptor is included 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. Refer to Appendix C page 36 for pin assignments.

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 Programming Guide section: Beeper Tones.
One Beep
*
When the scanner first receives power, both LEDs come on
together along with the beep-the green LED only flashes.
After the scanner performs this startup sequence, the
scanner is ready to scan.
When the scanner successfully reads a bar code, the green light
will flash and beep once (if programmed to do so). If the scanner
does not beep once and the green light does not flash, then the
bar code has not been successfully read.
Razzberry Tone
This tone is a failure indicator. Refer to failure modes page 11.
Three Beeps- after power up
***
When entering the program mode, the green LED will flash
while the scanner simultaneously beeps three times. The green
LED will continue to flash until the unit exits program mode.
Upon exiting program mode, the scanner will beep three times
and the green LED will stop flashing. When configured, 3 beeps
can also indicate a communications timeout during normal
scanning mode.

authorized service center.
This indicates the scanner has experienced a motor failure.
Return the unit for repair at an authorized service center.
If, upon power up, the scanner emits a continuous razzberry tone, then the scanner has an electronic failure.
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
11
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
the scanner has been dormant for a specified time and the laser
has turned off. To reactivate the unit, pass an object through
the scan field.
2.) If the scanner is not receiving power from the host or transformer, then the LEDs will not be on.
Steady Red
When the laser is on, the red LED is also on. The red LED will
remain on until the scanning period has expired.
Steady Red and Single Green Flash
When the scanner successfully reads a bar code, the green LED
will flash then beep once. If the green LED does not flash or the
scanner does not beep once, then the bar code has not been successfully read.
12
Steady Red and Steady Green
After a successful scan, the scanner transmits the data to the host
device. If the host is not ready to accept the information, the scanner’s green LED will remain on until the data can be transmitted.
The red LED will turn off when the scanning period expires.
Steady Red and Flashing Green
This indicates the scanner is in program mode. A razzberry tone
indicates that an invalid bar code has been scanned in this mode.
Steady Green
This indicates the scanner may be waiting for communication from
the host.
Flashing Green
This indicates the scanner is waking up from a dormant state in
response to an IR sensor activation. Refer to page 18.
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

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. This volume does not reflect
the entire length of all the laser lines. (Please refer to the Cross-Sectional Pattern in
this section, page 20).

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. 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.)
Verify that the type of bar code being read has been selected.
2. The scanner has been programmed for a character length lock, or a
minimum length and the bar code being scanned does not satisfy the
programmed criteria. Verify that the bar code that is being scanned falls
into the criteria. (Typical of Non-UPC/EAN codes.)
3. The scanner scans a bar code but the scanner locks up (green LED comes
on and stays on) after the first scan. The scanner is configured to support
some form of host handshaking but is not receiving the signal. If the scanner
is setup to support ACK/NAK, RTS/CTS, XON/XOFF or D/E, verify that the
host cable and host are supporting the handshaking properly.
4. The scanner scans and transmits but the data is not correct at the host.
Verify that the scanner’s data format matches that required by the host.
Make sure that the scanner is connected to the proper host port.
SYMPTOMS
Scanner beeps at some bar codes and NOT for others of the same bar code symbology
POSSIBLE CAUSE(S)/SOLUTION(S)
1. The print quality of the bar code is suspect.
2. The aspect ratio of the bar code is out of tolerance.
3. The bar code may have been printed incorrectly.
(check digit/character/or border problem.)

RS-232 Demonstration Program
If an RS-232 scanner is not communicating with your IBM compatible PC, key in the
following BASIC program to test that the communication port and scanner are working.
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. At this point, investigate whether the application
software and the scanner configuration match. If the applica-tion does not support RS232 scanners, a software wedge program that will take RS-232 data and place it into a
keyboard buffer may be needed. This program tells the PC to ignore RTS-CTS, Data Set
Ready (DSR) and Data Carrier Detect (DCD) signals. If the demostration program works
and yours still does not, jumper RTS to CTS and Data Terminal Reading (DTR) to DCD
and DSR on the back of your PC.

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. This connector plugs into different “J” positions on
various computer/interface boards. Since each computer/interface board is
different, the output signals are different.

Umständen versuchen, den Laser-Scanner selbst zu warten. Sehen Sie niemals in den Laserstrahl,
selbst wenn Sie glauben, daß der Scanner nicht aktiv ist. Öffnen Sie niemals den Scanner, um in
das Gerät hineinzusehen. Wenn Sie dies tun, können Sie sich einer lebensgefährlichen
Laserstrahlung aussetzen. Der Einsatz optischer Geräte mit dieser Laserausrüstung erhöht das
Risiko einer Sehschädigung.
N.B.
Dal controllo di questo apparecchio risulta che esso risponde ai valori limite per apparecchi
digitali della classe A conf. parte 15 delle direttive sulle telecomunicazioni dell’Autorità federale
statunitense. Questi valori limite sono stati fissati per garantire una protezione adeguata contro gli
effetti nocivi se questo apparecchio viene usato all’intero di un negozio. L’apparecchio genera,
utilizza e può emettere energia ad alta frequenza e, se non viene installato ed utilizzato
conformemente alle indicazioni fornite nel Manuale utente, può provocare disturbi al servizio
radiofonico. L’uso di questo apparecchio in zone residenziali causa molto probabilmente dei
disturbi. In questo caso l’utente è obbligato ad eliminare questi disturbi a sue spese. Qualsiasi
sostituzione o modifica non autorizzata all’apparecchio potrebbe rendere invalida l’autorizzazione
dell’utente all’uso dell’apparecchio.
N.B.
Questo apparecchio digitale non supera I valori limite per l’emissione di radiorumori da parte di
apparecchi digitali della classe A conformemente alle direttive per radiodisturbi del Ministero
canadese per l’Industria.
Attenzione
L’utilizzo di sistemi di controllo, di regolazioni o di procedimenti diversi da quelli decritti nel
presente Manuale può provocare dei raggi laser pericolosi per la vita. Il cliente non deve
assolutamente tentare di riparare egli stesso lo scanner laser. Non guardate mai nel raggio laser,
anche se credete che lo scanner non sia attivo. Non aprite mai lo scanner per guardare dentro
l’apparecchio. Se tuttavia lo fate, potete esporVi a dei raggi laser pericolosi per la vita. L’uso di
