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 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. "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. (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. Plug the
transformer into the AC outlet to supply power to the scanner. (A
socket-outlet shall be installed near the equipment and shall be easily
accessible.)
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.
3
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, configure the
scanner to match the host system requirements. Configure the scanner by
entering the program mode and scanning the appropriate 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.)

orientation choices are vertical or
horizontal. (Refer to Figure 4). To
use this stand, use the four 6-32 x ½
inch machine screws and four wood
screws to attach the unit to the back
plate and work surface. The maxi-
mum distance the screws should go
into the scanner is a ½ inch.
1. Drill four holes into the work surface that correspond with the holes
indicated by an XY in Figure 5.
2. To fasten the scanner to the back plate:
! For a horizontal mount, align the four holes on the back of the
scanner with the four clearance holes located on the back plate
marked with an X in Figure 5.
! For a vertical mount, align the four holes on the back of the
scanner with the four clearance holes located on the back plate
marked with a Y in Figure 5.

Parts of the 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, communica-tion 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 communi
cation cable from the scanner to a host
device. The communication cable may
include a power supply or it may be de
signed to draw power directly from the
host device. The standard TECH 7 has
one connector. (When 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 illuminated. 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
reactivate the unit, touch the touch plate. Secondly, if the scanner is not
receiving power from the host or transformer, then the LEDs will not turn on.
Flashing Red
This indicates the scanner has experienced a laser subsystem 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 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
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 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.

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 segnale 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.
11
Labels
There is one label located inside the window of the scanner noting that this
device is a CDRH Class IIa laser product and IEC 825 LASERKLASSE 1.
Also, on the scanner is a label located on the back of the unit. This label
contains information such as the model number, date of manufacture, serial
number, and approvals. The following are samples of the labels located on the
unit.
