Introduction
Metrologic’s TECH 8 laser bar code projection scanner is encased in an NEMA-12 steel case. The
scanner’s construction enables the scanner to operate in harsh surroundings, especially industrial
environments. Water-resistant, shock-resistant, and rugged, the TECH 8 scanner is also fast,
aggressive and reliable. It can register bar codes at a range of 203mm - 457mm (8" - 18") and can
autodiscriminate among all common codes.
Among the scanner’s many features is an ASIC (Application Specific Integrated Circuit) in the
decoding system that virtually eliminates misreads and MECCA (Metrologic Enhanced Code
©
Correcting Algorithm). MECCA enables the scanner to read poorly printed, wrinkled or even torn
©
bar codes on the first pass.
The scanner has been configured at the time of manufacture based on information supplied at the time
of order.

Labels
One label is found inside the window of the scanner noting that this device is a CDRH Class IIa
laser product and EN 60825-1 LASERKLASSE 1. Also, on the scanner is a label on the back of
the unit. This label contains information such as the model number, the date of manufacture and
the serial number. The following are samples of the labels that are found on the unit.
Applications and Protocols
The following chart lists the version identifiers for all the communication protocols. Listed on
each scanner is a model number. The model number includes the scanner number, revision label,
and denoted version identifier. For example, if the model number is MS870-B1, the scanner is an
MS870, B is the revision level, and 1 is the version identifier.

Maintenance
Smudges or dirt that appears on the scanner window can interfere with proper scanning.
Therefore, the window will need occasional cleaning.
1. Spray glass cleaner onto lint free, non-abrasive cleaning cloth.
2. Gently wipe the scanner window.
Configuration of the Scanner to the Host System
The scanner has been configured at the time of manufacture based on information supplied at the
time of order. If ScanSet™ is being used, refer to the ScanSet documentation for information on
how to configure your scanner.

Scanner Connections
In order for the scanner 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 60825-1.
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. Find the 19-pin female end of the scanner link cable and 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
will not receive power from a transformer, skip to Step 6.)
4. 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 shall be installed near the equipment and shall be easily accessible.)
5. Plug the transformer into the AC outlet to supply power to the scanner.
6. Power up the host system.
7. Scan a few items to verify that data is being properly transmitted between the scanner
and the host device.

Figure 1
Attaching the Scanner to the Stand and Work Surface
The scanner can be positioned in a vertical orientation with the Metrologic stand (Part #45478).
To attach the unit to the stand and work surface purchase the following: four 6-32 x ½"
(maximum length) machine screws and two #10 panhead or #8 countersunk wood screws.
1. Lay the scanner face down on a clean cloth to prevent any scratches from occurring on
the output window. Position the scanner so the red and green LEDs are pointed toward
yourself.
2. Lay the stand on the scanner with the angled bracket pointing up and toward yourself.
3. Align the four clearance holes to the four holes in the scanner’s case. Fasten the scanner
to the stand by inserting the four 6-32 x ½" screws into the four holes in the scanner’s
case.
4. Drill two holes into the work surface that correspond with the holes in the
216mm - 95mm (8.5" x 3.75") base of the stand.
5. Use two panhead or countersunk wood screws to attach the scanner and stand to the
work surface. (Refer to Figure 1)

Figure 4
Scanning Bar Codes
The depth of field for the scanner is 203mm to 457mm (8" to 18") from the scanner window. The
symbol must be passed through the scan area in order for the scanner to recognize the bar code.
(Refer to Figure 2)
