Introduction  
®
Metrologic's TECH 7 laser bar code projection scanner is encased in  
an NEMA-12 steel case. The case construction enables the scanner  
to operate in harsh surroundings, especially industrial environments.  
Water-resistant, shock-resistant, and rugged, the TECH 7 is also fast,  
aggressive and reliable. It can register bar codes at a range of  
76mm - 254mm (3" - 10") and can autodiscriminate among all  
common codes.  
To suit particular applications, two different scan patterns are  
available: an omnidirectional pattern of 20 interlocking lines (Model  
MS770); or a 12-line raster pattern (Model MS775). The scanner has  
a VLD design, a scan speed of up to 2000 lines per second, and uses  
less than 8 watts of power.  
Other features include an Application Specific Integrated Circuit  
©
(ASIC) and MECCA (Metrologic Enhanced Code Correcting  
Algorithm). An Application Specific Integrated Circuit (ASIC) is in the  
©
decoding system and virtually eliminates misreads. MECCA  
(Metrologic Enhanced Code Correcting Algorithm) enables the TECH  
7 scanner to read poorly printed, wrinkled or even torn bar codes on  
the first pass.

Scanner Installation  
To maintain compliance with applicable standards, all circuits con-  
nected to the scanner must meet the requirements for SELV (Safety  
Extra Low Voltage) according to EN 60950. To avoid potential prob-  
lems, do not power up the scanner until the communication cable  
is secured to the host.  
1. "Power off" the host system.  
2. Locate the 19-pin female end of the scanner link cable and  
find the widest key located above pins L and A. Align this key  
with the corresponding key on the scanner box's Mil spec  
connector. While pushing in on the connector, rotate the ring  
clockwise until it locks into place with a click.  
3. Connect the other end of the communication cable to the host  
device.  
Note: The following statement is applicable if the optional  
power adapter available through Metrologic does not power  
the bar code scanner and the scanner receives power from a  
host device such as a computer system.  
Caution: To maintain compliance with standards CSA  
C22.2 No. 950/UL 1950 and norm EN 60950, the  
power source must meet applicable performance  
requirements for a limited power source.  
If the scanner is powered by the host, skip to Step 5.  
4. Check the AC input requirements of the transformer/power  
supply to make sure the voltage matches an available AC  
outlet. A socket-outlet must be installed near the  
equipment and be easily accessible. 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.

Configuration to the Host System  
The scanner is shipped from the factory programmed to a set of  
default conditions noted in the ScanSelect™ Scanner Programming  
Guide by an asterisk that appears before the brief definition located  
next to the bar code.  
In order for the scanner to communicate with a host system properly, it  
may need to be programmed. Since each host system is unique, con-  
figure the scanner to match the host system requirements. Configure  
the scanner by entering the program mode and scanning the appro-  
priate bar codes that appear in the ScanSelect Scanner Programming  
®
Guide. (To use ScanSet , refer to the ScanSet documentation for  
information on how to configure a 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. 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 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.

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.

Visual Indicators  
There is a red and green LED at the top of the scanner. When the  
scanner is on, the flashing or stationary activity of the LEDs indicates  
the status of the scan and scanner.  
Steady Green  
When the laser is on, the green LED is also on. This  
occurs when an object is in the scan field.  
Steady Green; Red Flash  
When the scanner successfully reads a bar code, the red  
LED will flash then beep once. If the red LED does not  
flash or the scanner does not 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.  
No Red or Green LED  
There are two reasons why the LEDs will not be illumi-  
nated. First, if the scanner is receiving power and the  
LEDs are not on, then the scanner has remained dormant  
for a specified time and the laser has turned off. To reacti-  
vate the unit, touch the touch plate. Secondly, if the  
scanner is not receiving power from the host or trans-  
former, then the LEDs will not turn on.  
Flashing Red  
This indicates the scanner has experienced a laser sub-  
system failure. Return the unit for repair at an authorized  
service center.

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 sig-  
nifie 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 unconcessionnaire 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 bes-  
timmten 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.

Segnali Ottici  
Sullo scanner si trovano due diodi luminosi: uno rosso e uno verde.  
Quando lo scanner è inserito, i diodi luminosi, che possono o essere  
accesi in continuazione o lampeggiare, Vi informano sullo stato della  
scansione e dell'apparecchio.  
Né il diodo luminoso rosso né quello verde sono accesi  
Vi sono due possibili cause se i diodi luminosi non sono accesi. Prima  
causa: se lo scanner viene alimentato e i diodi luminosi non sono  
accesi, lo scanner è rimasto disattivato per un determinato periodo e il  
laser è spento. Per riattivare l'unità dovreste muovere un oggetto  
davanti al sensore a infrarossi. Seconda causa: se lo scanner non  
viene alimentato né dal calcolatore host né dal trasformatore, i due  
diodi luminosi non sono accesi.  
Il diodo luminoso verde è acceso  
Quando il laser è inserito, è acceso anche il diodo luminoso verde.  
Questo si ha quando un oggetto si trova nella zona di scansione. Il  
diodo luminoso verde è acceso fino al raggiungimento del timeout  
infrarossi oppure fino allo spegnimento dello scanner.  
Il diodo luminoso verde è acceso; quello rosso lampeggia  
Dopo la lettura riuscita di un codice a barre da parte dello scanner il  
diodo luminoso rosso lampeggia e quindi viene emesso un unico seg-  
nale beep. Se il diodo luminoso rosso non lampeggia oppure lo  
scanner non emette un segnale beep, ciò significa che la lettura del  
codice a barre non è riuscita.  
Sono accesi sia il diodo luminoso rosso che quello verde  
Dopo la scansione riuscita lo scanner trasmette i dati all'host. Se l'host  
non è pronto per accettare i dati, il diodo luminoso rosso dello scanner  
è acceso fino a che i dati possono essere trasmessi.  
Il diodo luminoso rosso e quello verde sono accesi in alternanza  
Ciò indica che lo scanner si trova nella modalità di programmazione.  
Il diodo luminoso rosso è acceso  
Ciò indica che lo scanner si trova nella modalità ScanSet.  
Il diodo luminoso rosso lampeggia  
Ciò indica che lo scanner ha un guasto a livello del laser. Fate riparare  
l'apparecchio da un centro di assistenza autorizzato.

Version "15" Pin Assignments for Light Pen Emulation  
Each TECH 7 scanner has a 19-pin male Mil spec connector that is  
located on the side of the unit. To connect the scanner to the host  
device, use a communication cable with a female Mil spec connector.  
The communication cable may include a power supply or it may be  
designed to draw power directly from the host device. This item can  
be ordered when the scanner is purchased.  
The Version "15" scanner is designed to be used for Light Pen  
Emulation communication.  
The following is a list of pin assignments. The pin numbers are  
impressed on the male Mil spec connector. For easier reference, refer  
to Figure 10 for pin locations.

Appendix D  
Notices  
This equipment has been tested and found to comply with limits for a Class A digital device, pursuant  
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against  
harmful interference when the equipment is operated in a commercial environment. This equipment  
generates, uses and can radiate radio frequency energy and, if not installed and used in accordance  
with the instruction manual, may cause harmful interference to radio communications. Operation of  
this equipment in a residential area is likely to cause harmful interference, in which case the user will  
be required to correct the interference at his own expense. Any unauthorized changes or modifica-  
tions to this equipment could void the users authority to operate this device.  
Notice  
This Class A digital apparatus complies with Canadian ICES-003.  
Caution  
Use of controls or adjustments or performance of procedures other than those specified herein may  
result in hazardous laser light. Under no circumstances should the customer attempt to service the  
laser scanner. Never attempt to look at the laser beam, even if the scanner appears to be nonfunc-  
tional. Never open the scanner in an attempt to look into the device. Doing so could result in haz-  
ardous laser light exposure. The use of optical instruments with the laser equipment will increase  
eye hazard.  
Remarque  
Cet appareil numérique de la classe A est conformé a la norme NMB-003 du Canada.  
Attention  
L'emploi de commandes, réglages ou procédés autres que ceux décrits ici peut entraîner de graves  
irradiations. Le client ne doit en aucun cas essayer d'entretenir lui-même le scanner ou le laser. Ne  
regardez jamais directement le rayon laser, même si vous croyez que le scanner est inactif.  
N'ouvrez jamais le scanner pour regarder dans l'appareil. Ce faisant, vous vous exposez à une ray-  
onnement laser mortel. L'emploi d'appareils optiques avec cet équipement laser a-ugmente le risque  
d'endommagement de la vision.  
Achtung  
Die Verwendung anderer als der hierin beschriebenen Steuerungen, Einstellungen oder Verfahren  
kann eine lebensgefährliche Laserstrahlung hervorrufen. Der Kunde sollte unter keinen 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 aus-  
setzen. Der Einsatz optischer Geräte mit dieser Laserausrüstung erhöht das Risiko einer  
Sehschädigung.  
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 d-entro l’apparecchio. Se tut-  
tavia lo fate, potete esporVi a dei raggi laser pericolosi per la vita. L’uso di apparecchi ottici con  
questo equipaggiamento laser aumenta il rischio di danni alla vista
