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.

Parts of Scanner
1 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.
2 Speaker
The speaker emits a beep when a bar code has been
decoded.
3 Laser Output Window
This aperture emits the laser light.
4 Mil spec Connector
The 19-pin male Mil spec connector was designed to connect
a communication cable from the scanner to a host device.
The communication cable may include a power supply or it
may be designed to draw power directly from the host device.
The standard TECH 7 has one connector. (When the atrium
option is installed, a second connector is installed on the unit
to connect the MX001 Industrial Control Interface box.)

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.
