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.

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.)

Stand Installation

With the Metrologic stand (Part
#45475), the scanner can be
positioned in one of two directions.
The two orientation choices are
vertical or horizontal. (Refer to
Figure 1)

To install this stand, use the four 6­32 x ½ inch machine screws and two
#10 panhead wood screws.

Figure 1

1. Drill two holes into the work
surface that are the same size
and distance as the holes on
the stand base. (Refer to Figure

2)

2. Use the two #10 panhead
wood screws to attach the
stand to the work surface.

3. To fasten the scanner:

! For a horizontal mount,

align the four holes on the
back of the scanner with
the four clearance holes
located on the stand
marked with an X in
Figure 3.

! For a vertical mount, align

the four holes on the back
of the scanner with the
four clearance holes
located on the stand
marked with a Y in Figure

3.

4. Fasten the scanner to the stand by inserting the four 6-32 x ½ inch
screws into the four holes in the scanner’s case.

Back Plate Installation

With the Metrologic back plate
(Part #45473), position the scanner
in one of two directions. The two
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 maxi­mum 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.

Figure 4

3. Fasten the scanner to the back plate by inserting the four 6-32 x ½ inch
screws into the four holes in the scanner’s case. Fasten the scanner and
back plate to the work surface.

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.

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.)
