MT82U One-piece Compact 2D Scan Engine provides snappy scanning performance
at a competitive cost and compact form factor. With its all-in-one design, MT82U 2D
scan engine can be easily integrated with specific applications such as access control,
lottery kiosk and consumer electronics.
The MT82U 2D Scan Engine consists of 1 illumination LED, 1 aimer LED and a
high-quality image sensor with a microprocessor that contains powerful firmware to
control all aspects of operations and enable communication with the host system over
the standard set of communication interfaces.
Two interfaces, UART & USB, are available. UART interface communicates with the
host system over TTL-level RS232 communication; USB interface emulates a USB
HID Keyboard or Virtual COM port device and communicates with the host system
over USB.

*Warning:
1. Pull low at power-up

operation continues until a barcode is
successfully decoded or the trigger is released
(pull high). To proceed to the next scanning
operation, release (pull high) first and press (pull
low) the trigger again.
A minimum of 50ms
interval is reco
mmended between two trigger
signals.

1. At power-up, the MT82U sends the Power-Up signals over Buzzer and LED
pins as an indication that the MT82U enters Standby Mode and is ready for
operation.
2. Once the MT82U triggered by either hardware or software method, MT82U
will emit a beam of light which is aligned with the sensor’s field of view.
3. The area image sensor captures the image of barcode and produces an
analog waveform, which is sampled and analyzed by the decoder firmware
running on the MT82U.
4. Upon a successful barcode decoded, the MT82U turns off the illumination
LEDs, sending the Good Read signals over Buzzer and LED pins and
transmitting the decoded data to the host.

The scan engine is designed specifically for integration into customer's housing for
OEM applications. However, the scan engine’s performance will be adversely affected
or permanently damaged when mounted into an unsuitable enclosure.
Warning: The limited warranty is void if the following recommendations are not
adhered to when mounting the scan engine.

All scan engines are shipped in ESD protective packaging due to the sensitive
nature of the exposed electrical components.
1. ALWAYS use grounding wrist straps and a grounded work area when
unpacking and handling the scan engine.
2. Mount the scan engine in a housing that is designed for ESD protection and
stray electric fields.

When securing the scan engine by utilizing the machine screws:
1. Leave sufficient space to accommodate the maximum size of the scan engine.
2. Do not exceed 1kg-cm (0.86 lb-in) of torque when securing the scan engine to
the host.
3. Use safe ESD practices when handling and mounting the scan engine.

Following are descriptions of three popular window materials:
1. Poly-methyl Methacrylic (PMMA)
2. Allyl Diglycol Carbonate (ADC)
3. Chemically tempered float glass
Cell Cast Acrylic (ASTM: PMMA)
Cell cast Acrylic, or Poly-methyl Methacrylic is fabricated by casting acrylic
between two precision sheet of glass. This material has very good optical quality,
but is relatively soft and susceptible to attack by chemicals, mechanical stress
and UV light. It is strongly recommended to have acrylic hard-coated with
Polysiloxane to provide abrasion resistance and protection from environmental
factors. Acrylic can be laser-cut into odd shapes and ultrasonically welded.
Cell Cast ADC, Allyl Diglycol Carbonate (ASTM: ADC)
Also known as CR-39TM, ADC, a thermal setting plastic widely used for plastic
eyeglasses, has excellent chemical and environmental resistance. It also has an
inherently moderate surface hardness and therefore does not require
hard-coating. This material cannot be ultrasonically welded.
Chemically Tempered Float Glass
Glass is a hard material which provides excellent scratch and abrasion
resistance. However, un-annealed glass is brittle. Increased flexibility strength
with minimal optical distortion requires chemical tempering. Glass cannot be
ultrasonically welded and is difficult to cut into odd shapes.
Property Description
Spectral Transmission 85% minimum from 635 to 690 nanometers
Thickness < 1 mm
Coating
Both sides to be anti-reflection coated to provide 1%
maximum reflectivity from 635 to 690 nanometers at
nominal window tilt angle. An anti-reflection coating can
reduce the light that is reflected back to the host case.
Coatings will comply with the hardness adherence
requirements of MIL-M-13508.

The window size should ensure that field of view is not blocked, and the illumination
area should not be blocked as well. For the size of window, please refer to above
diagram of each optical area.

In the aspect of window, the performance of MT82U will be reduced due to any kind of
scratch. Thus, reducing the damage of window, there are few things have to be
noticed.
1. Avoid touching the window as much as possible.
2. When cleaning the window surface, please use non-abrasive cleaning cloth, and
then gently wipe the host window with the cloth that is already sprayed with glass
cleaner.
