Introduction

The MS700i Series Scanners are high throughput projection scanners that

incorporate the latest in VLD (Visible Laser Diode) ASIC/VLSI and surface

mount technologies. Each scanner consumes only 8 watts of power and can

directly connect to many host systems that can support a scanning device. One

thoughtful feature is a “sleep mode” that turns the laser and motor off when not

in use. Other features include easy-to-see LED indicators that can be viewed

from the top or front and a volume control card that can be scanned to control

volume levels. There are two programming methods: through the

ScanSelect™ programming guide or through ScanSet™ (an IBM PC

compatible software program.)

With a scan speed of 2,000 lines per second, these scanners aggressively scan

poorly printed bar codes and read torn and bent UPC, EAN and JAN bar

codes immediately on the first pass at any roll angle. For close scanning, the

MS700i and MS715i’s depth of field of 0.0mm - 178mm (0" - 7") is ideal. To

accommodate applications where scanning items farther away from the scan

window is preferred, the MS720i’s depth of field of 178mm - 381mm (7" -

15") is ideal.

Unpacking List

The shipping carton should contain the following:

! Installation and User’s Guide (MLPN: 2178)

! ScanSelect™ Scanner Programming Guide (MLPN: 2186)

! Volume Control Card (MLPN: 2346)

! MS700i /MS715i or MS720i Laser Bar Code Projection Scanner

! Power Supply (optional)

! Communication cable with connection for power supply (optional) or

Communication Cable (optional)

! Stand #45483 (optional)

Scanner Connections to the Host

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. To avoid potential problems, do not power up the

scanner until the communication cable is secured to the host.

1. Turn off the host system.

2. Connect the 25-pin D-type connector on the scanner’s head cable to the

communication cable. Connect the other end of the communication

cable to the host device. (If the scanner will not receive power from a

transformer, skip to Step 5.)

3. If the scanner will receive power from an external power source, check

the AC input requirements of the transformer to make sure the voltage

matches the AC outlet. (A socket-outlet can be installed near the

equipment so it will be easily accessible.)

4. Plug the transformer into the side of the female D-type connector

located on the communication cable. Plug the transformer into the AC

outlet to supply power to the scanner.

5. Power up the host system.

Note: When the scanner first receives power, the LEDs will flash and

then the scanner will beep once. After the scanner performs this

startup sequence, the green LED will remain on for a specified

time indicating that the laser is on.

4

Configuration of the Scanner to the Host System

The scanner is shipped from the factory programmed to a set of default

conditions. These default conditions are in the Default Settings section of this

guide pages 36-41 and in the ScanSelect™ Scanner Programming Guide. The

default settings in the ScanSelect guide have an asterisk that appears before

the brief definition next to the bar code.

For the scanner to properly communicate with the host system, it needs to be

programmed to meet the specific scanning needs. Since each host system is

unique, configure the scanner to match the host system requirements.

Configure the scanner by entering program mode and scanning the appropriate

bar codes that appear in the ScanSelect Scanner Programming Guide. (When

using ScanSet™, refer to the ScanSet documentation for information on how

to configure the scanner.)

1. Connect the scanner to the host system (Refer to the Scanner

Connections to the Host section in this guide).

2. Enter program mode by scanning the ENTER/EXIT program mode bar

code as the first bar code after a power up cycle. (The unit will beep

three times)

3. Scan the appropriate bar code(s) that appear in the ScanSelect Scanner

Programming Guide. (Reveal only one bar code to the scanner each

time. With your hand, cover the bar code that is not to be scanned.)

4. Exit program mode by scanning the ENTER/EXIT program mode bar

code again. (The new options will be saved and the scanner is ready for

normal operation.)

Note: Non-RS-232 interfaces chosen in Section B of the ScanSelect

Programming Guide do not match the default settings loaded when

the same interface is selected with ScanSet.

5

CLONING

Cloning Feature

To program several scanners with the same settings, use the Cloning feature.

This is done by connecting the cloning cable (MLPN: #51544) between two

scanners.

1. Turn off both scanners.

2. Connect the cloning cable between the two scanners.

3. Turn both scanners on by plugging in the transformers.

4. Once each scanner is ready, scan the cloning bar code with the scanner

that has the settings that need to be transferred to the other scanner.

Version 11 IBM 46XX Scanner

Output Format: IBM RS-485 serial input/output for the 4680 and 4690

(46XX) point-of-sale terminals

The Version 11 46XX interface can be used in several different ways. Both the

46XX terminal and the scanner must be configured to match each other.

Warning: Power to the scanner and 46XX terminal should be turned off

before making physical connection.

The 4680 and 4690 series terminals have different types of physical ports for

connecting bar code scanners. Scanner ports include Port 5B, Port 17, and

Port 9? (? = A, B, C, or E). A Port 9 type connector is present on all versions

of the 46XX families of terminals. That is one reason it is the normal point of

connection for Metrologic scanners. Another reason is that there is enough 12

volt power available to operate many Metrologic scanners. If the terminal

configuration requires use of a different physical port for connecting bar code

scanners, contact Metrologic to get particular adaptor cable information.

No matter what port is in use for the physical connection, all devices use a

common communications bus inside the 46XX terminal. Each device uses a

different address when it must communicate. The terminal must be configured

to look for a device at a logical address.

The IBM 1520 mode/address was selected as a default because it was the first

IBM 46XX family scanner to support UPC/EAN, Code 39 and Interleaved 2

of 5. The Version 11 scanner formats Codabar, Code 128, and Code 93 using

the Code 39 function code designation supported by the IBM device driver for

this scanner type. Other emulation modes currently available are the IBM

3687-2 Port 17 fixed scanner and the Port 9B IBM 4500 CCD hand-held bar

code reader. One of these other emulation modes may be needed depending on

which operating system (4680.OS, 4690.OS, POS/DOS or DOS/RIPPS) is in

use at the site.

Note: The IBM 4683 and IBM 4684 terminals have a good proven track

record of supplying power to Metrologic scanners. The IBM 4693

and IBM 4694 terminals may be restricted from supplying power to

certain scanner models. Specifically, Metrologic currently

recommends using an external power supply for the scanner when

connecting to an IBM 4694. Metrologic has no recommendations at

this time for IBM 4693 terminals.

7

Configuring the Scanner

Located in the Version 11 scanner are two computer boards. One board is for

decoding and the other for 46XX IO processing. The decode board is

configured using ScanSet™ or ScanSelect™ while the IO board is configured

with an internal DIP Switch bank.

For UPC/EAN scanning, the decode board should be set as follows:

Enable IBM 4680 Communication

Enable UPC/EAN

Beep after Transmit

Enable Communication Timeouts

Transmit UPC-A Check Digit

Transmit UPC-E Check Digit

These settings configure the decode board to beep after transmitting the data to

the terminal device driver. If the data does not clear the communications buffer

within two seconds, it is discarded without giving the operator a good scan

indication. This accommodates newer versions of the IBM device drivers that

enable/disable scanning in many different situations.

The default setting of the interface board is to emulate the IBM 1520 hand

scanner that supports UPC/EAN and alphanumeric code types. The following

is a list of switch settings for the internal interface board that handles the

46XX SIOC communications.

There are eight DIP switches on the board that are both software and hardware

switches.

Switch 1 Switch 2 Emulation Mode

OFF OFF Port 5B, IBM 1520 Model 2 Laser Scanner

(default setting)

OFF ON Port 9B, CCD (IBM 4500/Opticon)

ON OFF Port 17, IBM 4014 Adaptor for 3687-2 to 468X

ON ON Reserved

Switch 3 Reserved (Should be OFF)

Switches 4, 5, 6, and 7 Must be ON

Switch 8 Should be OFF (Reserved)

8

Configuring the IBM 46XX

The 4683 and 4693 terminals are configured on the store controller. The 4684

and 4694 terminals are typically configured on the individual terminals.

Follow the appropriate guide for the type of equipment.

IBM 4683 and 4693 Terminals Driven by a 46XX Store Controller

Running 4680.OS or 4690.OS

Access the terminal configuration menu on the store controller. If not already

selected, select an IBM 1520 laser hand scanner (4680.OS Port 5B), an IBM

4500 hand-held bar code reader (CCD, 4680.OS Port 9B), or an IBM 3687-2

fixed scanner (4680.OS Port 17) that matches the configuration of the scanner.

Regarding the 4690.OS, at the time of this printing, Metrologic does not know

exactly which terminal port configuration screen is used for selecting scanners.

It should be listed under the Port 9A, 9B, 9C, or 9E sections. The 4693

terminal has a Port 5B that was originally used for the IBM 1520 scanner.

While IBM has withdrawn this product, it was not clear how terminal

configuration and device driver support would be provided for the installed

base of users.

Save the configuration and activate it for the desired terminals. Download the

configuration to the terminal(s) per standard procedures.

IBM 4684 and 4694 Systems

Initialize the RIPPS drivers for a hand scanner if hand scanner emulation was

selected. Initialize the RIPPS drivers for a "POS scanner" if the 3687-2

scanner has been selected.

Scanner Installation to a PC Keyboard Port

The MS700i/MS715i/MS720i/ scanner (version 17) provides keyboard

emulation by converting the scanned bar code data to the PC keyboard scan

code equivalent. The following are the supported keyboard and country types:

PC Type

! AT (includes IBM PS/2 and compatible models 50, 55, 60, 80)

®

! XT

! PS/2 (includes IBM PC and compatible models 30, 70, 8556)

Keyboard Country Type

! USA ! United Kingdom

! France ! Germany

! Italy ! Spain

! Belgium ! Swiss

The communication cable kit (MLPN: 45927) has a communication cable

with one (1) 5 Pos female DIN connector and one (1) 6 Pos male mini DIN

connector. The kit also includes an adaptor cable. This cable allows the

scanner to plug into an IBM PC XT or AT compatible computer or a PS/2

®

computer and keyboard.

With the appropriate communication cable, the scanner will also provide RS-

232 or light pen emulation interface. When configuring the scanner for one

interface versus another, change all necessary parameters for that particular

interface. For instance, to configure the scanner for keyboard wedge emulation,

recall defaults, select the PC type, keyboard country type and intercharacter

delay. For further information, refer to the ScanSelect™ Scanner Programming

Guide or ScanSet™ Scanner Configuration Guide.

Figure 1

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. When connecting to

a PS/2 computer,

attach to the com-

munication cable

(#51573) the 5M 6F

adaptor to the

female connector

and the 5F 6M

adaptor to the male

connector.

2. If the PC is on, exit

the application and

turn the PC off.

3. Disconnect the keyboard from the PC.

4. Plug the communication cable to the PC and the keyboard.

(Refer to Figure 1).

5. Connect the 25-pin D-type connector on the scanner’s head cable to the

communication cable.

6. Check the AC input requirements of the transformer to make sure the

voltage matches the AC outlet.

(A socket-outlet shall be installed near the equipment and shall be

easily accessible.)

7. Plug the transformer into the side of the female D-type connector

located on the communication cable. Plug the transformer into the AC

outlet to supply power to the scanner.

8. Turn the PC on.

11

PC Application Note:

For most applications, it will be desirable to disable linefeed transmission. For

non-USA keyboards, 10 mesc is probably the best intercharacter delay.

Network system installations, may require tuning of the intercharacter and

inter scan code options.

Note:

Once the scanner connects to the PC, the PC can be turned on and will operate

normally even if the scanner's transformer plug is not in. How-

ever, bar codes will not be read until the scanner receives power. When

the scanner first receives power, the LEDs will flash and then the scanner

will beep once. After the scanner performs this startup sequence, the

green LED will remain on for a specified time indicating the laser is on.

Figure 2

Installation of the MS700 Series Stand

The following are components used to build the MS700 Series stand

(MLPN: 45483):

1 Shoe Mount 4 Four Wood Screws

2 Stand Cover 5 One Machine (¼-20) Screw

3 Stand Base 6 Internal Lock Washer

7 Flexible Shaft

1. Use the 2½ inch x 2½ inch stand base to mark the position for pilot

holes.

2. Use the four wood screws to secure the base to the work surface.

3. Position the stand cover on top of the stand base.

4. Screw the flexible shaft to the stand base.

5. Place the internal lock washer on top of the flexible shaft and then

screw the shoe to the shaft with the machine screw.

13

Figure 3

Attaching the Scanner to the Stand

Once the stand is securely mounted to the work surface, attach the scanner.

The scanner has a “foot” that is at the bottom of the scanner. This foot fits into

the “shoe” attached to the top of the stand. This construction helps prevent the

scanner from being knocked from the stand.

1. To prevent obstruction when sliding the scanner into place, loosen the

small screw (A) located in the center of the long part of the shoe with a

3/32" hex key wrench. (Refer to Figure 3)

2. Align the foot of the scanner with the shoe of the stand and slide the

scanner into position.

3. Tighten the small screw (A) located at the center of the long part of the

shoe. This screw holds the scanner in place.

Note: Fasten the stand to the work surface before adjusting the angle of

the flexible shaft. To adjust the angle, firmly hold the shaft and

push the shaft to a north, south, east, or west direction.

Figure 4

MS700i and MS720i Series Features

1 Speaker The sound of a beep emits from here when the

scanner performs a good read of a bar code.

2 Green and Red LEDs When the green LED is on, this indicates that

the unit is receiving power and the laser is on.

When the red LED flashes on, the scanner has

read a bar code successfully. When the red

light turns off, communication to the host is

complete.

3 InfraRed Object When a specified time has elapsed

Sensor without any scanning, the unit will enter a

“standby” mode. The scanner will not return

to scanning until an object or a wave your

hand is passed in front of the IR sensor.

4 Head Cable This cable can connect directly to the host

device or to a communication cable.

5 Output Window This aperture emits laser light.

15

Visual Indicators

There is a red LED and a green LED located on the scanner. When the scanner is on,

the flashing or stationary activity of the LEDs alert you to the status of the scan and

scanner.

No Red or Green LED

There are two reasons why the LEDs will not be illuminated. First, if the scanner is

receiving power and the LEDs are not on, then the scanner has remained dormant for a

specified period of time and the laser has turned off. To reactivate the unit, wave an

object in front of the IR sensor. Secondly, if the scanner is not receiving power from the

host or transformer, then the LEDs will not turn on.

Steady Green

When the laser is on, the green LED is also on. This occurs when an object is in the

scan field. The green LED will remain on until the IR time-out has elapsed or until the

scanner is turned off.

Steady Green; Red Flash

When the scanner successfully reads a bar code, the red LED will flash followed by one

beep. If you do not see the red LED flash or the scanner beep once, then the bar code

has not been successfully read.

Steady Red and Green

After a successful scan, the scanner transmits the data to the host device. When the host

is not ready to accept the information, the scanner’s red LED will remain on until the

data can be transmitted.

Alternating Red and Green

This indicates the scanner is in program mode.

Steady Red

This indicates the scanner is in ScanSet mode.

Flashing Red

This indicates the scanner has experienced a laser subsystem failure. Return the unit for

repair at an authorized service center.

16

Signaux optiques

Sur la partie supérieure du scanner se trouvent une diode LED rouge et une diode LED

verte. Quand le scanner est sous tension, les diodes rouge et verte clignotantes ou

allumées vous informent sur l'état du scanner.

Ni la diode rouge, ni la diode verte n'est allumée

Il existe deux raisons possibles pour que les diodes ne s'allument pas. Premièrement: si

le scanner reçoit de l'énergie sans que les diodes ne s'allument, le scanner est resté sans

servir pendant une certaine période et le laser est désactivé. Pour le réactiver, passer un

objet devant le palpeur infrarouge. Deuxièmement: quand le scanner ne reçoit de

l'énergie ni de l'ordinateur central, ni du transformateur, les diodes restent éteintes.

La diode verte reste allumée

Quand le laser est en service, la diode verte s'allume également. C'est le cas quand un

objet se trouve devant le palpeur. La diode verte reste allumée tant que la temporisation

de l'infrarouge dure ou jusqu'à ce que le scanner soit désactivé.

La diode verte reste allumée; la diode rouge clignote

Après lecture avec succès d'un code à barres par le scanner, la diode rouge se met à

clignoter, suivie d'un bip sonore unique. Si la diode rouge ne clignote pas ou quand

aucun bip sonore n'est émis, cela signifie que le code à barres n'a pas pu être lu avec

succès.

Les diodes rouges et vertes restent allumées

Une fois la lecture effectuée avec succès, le scanner transmet les données à l'ordinateur

central. Si ce dernier n'est pas prêt à recevoir les données, la diode rouge du scanner

reste allumée jusqu'à ce que les données puissent être transmises.

Les diodes rouges et vertes clignotent en alternance

Indique que le scanner se trouve en mode de programmation.

La diode rouge reste allumée

Indique que le scanner se trouve en mode ScanSet.

Diode rouge clignotante

Indique une panne de laser pendant la lecture. Veuillez envoyer votre appareil chez un

concessionnaire pour réparation.

Optische Anzeigen

Auf dem Scanner befinden sich eine rote und eine grüne Leuchtdiode. Bei

eingeschaltetem Scanner geben Ihnen die blinkenden bzw. feststehenden

Leuchtdiodenanzeigen Aufschluß über den Abtast- und Scannerstatus.

Weder rote noch grüne Leuchtdiodenanzeige

Es gibt zwei mögliche Gründe, weshalb die Leuchtdiodenanzeigen nicht aufleuchten.

Erstens: Wenn der Scanner mit Energie versorgt wird und die Leuchtdiodenanzeigen

nicht aufleuchten, so ist der Scanner für einen bestimmten Zeitraum untätig geblieben,

und der Laser ist abgeschaltet. Zur Reaktivierung der Einheit sollten Sie ein Objekt vor

dem Infrarot-Sensor hin- und herbewegen. Zweitens: Wenn der Scanner weder vom

Hostrechner noch vom Transformator Energie erhält, so leuchten die

Leuchtdiodenanzeigen nicht auf.

Feststehende grüne Anzeige

Wenn der Laser in Betrieb ist, leuchtet die grüne Leuchtdiodenanzeige ebenfalls auf.

Dies ist dann der Fall, wenn sich ein Objekt im Abtastfeld befindet. Die grüne

Leuchtdiodenanzeige leuchtet solange auf, bis das Infrarot-Timeout abgelaufen ist, oder

bis der Scanner abgeschaltet wird.

Feststehende grüne Leuchtanzeige; rote Blinkanzeige

Nach erfolgreichem Lesen eines Barcodes durch den Scanner blinkt die rote

Leuchtdiodenanzeige auf, gefolgt von einem einmaligen Piep-Signal. Blinkt die rote

Leuchtdiodenanzeige nicht auf oder sendet der Scanner kein Piep-Signal aus, so konnte

der Barcode nicht erfolgreich gelesen werden.

Feststehende rote und grüne Leuchtanzeige

Nach erfolgreichem Abtasten überträgt der Scanner die Daten an das Hostgerät. Falls

das Hostgerät zur Datenannahme nicht bereit ist, leuchtet die rote Leuchtdiodenanzeige

des Scanners solange auf, bis die Daten übertragen werden können.

Alternierende rote und grüne Leuchtanzeige

Zeigt an, daß sich der Scanner im Programmiermodus befindet.

Feststehende rote Leuchtanzeige

Zeigt an, daß sich der Scanner im ScanSet-Modus befindet.

Aufblinkende rote Leuchtanzeige

Zeigt an, daß beim Scanner ein Laserausfall vorliegt. Bringen Sie das Gerät zur Reparatur in ein

Vertragsservicecenter.
