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
Correcting Algorithm). MECCA

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 60950.

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.

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

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 should be installed near the equipment and must be easily accessible.)

norm EN 60950, the power source must meet applicable performance
requirements for a limited power source.

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.

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 (2) #10 pan head or two (2) #8 countersunk wood
screws. (Refer to figure 1)

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 you.

2. Lay the stand on the scanner with the angled bracket pointing up and toward you.

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 - 96mm (8.5" x 3.80") base of the stand.

5. Use two pan head or countersunk wood screws to attach the scanner and stand to the
