1. INTRODUCTION INTRODUCTION
The MT80 2D Mini Scan Engine is designed for 1D Barcode and QR Code high
performance barcode scanning with easy integration. MT80 is ideal for integration into
data terminals and other small mobile devices.
The MT80 consists of 2 illumination LEDs, a high-quality image sensor and a 32-bit
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 device and communicates with the host system over USB.

2- -4. 4. Operat Operation ion Method Method
1. At power-up, the MT80 sends the Power-Up signals over Buzzer and LED
pins as an indication that the MT80 enters Standby Mode and is ready for
operation.
2. Once the MT80 triggered by either hardware or software method, it will emit a
narrow, horizontal slab of light which is aligned with the sensor’s field ofview.
3. The linear image sensor captures the linear image of barcode and produces
an analog waveform, which is sampled and analyzed by the decoder
firmware running on the MT80.
4. Upon a successful barcode decoded, the MT80 turns off the illumination
LEDs, sends the Good Read signals over Buzzer and LED pins and transmits
the decoded data to the host.

3. .INSTALLATION INSTALLATION
The MT80 scan engine is designed specifically for integration into customer's housing
for OEM applications. However, the MT80’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 MT80.
3-1.
3-1. Electrostatic Electrostatic Di Discharge scharge Cautions Cautions
All MT80s 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 MT80.
2. Mount the MT80 in a housing that is designed for ESD protection and stray
electric fields.
3-2.
3-2. Mechanical Mechanical Dimension Dimension
When securing the MT80 by utilizing the machine screws:
1. Leave sufficient space to accommodate the maximum size of the MT80.
2. Do not exceed 1kg-cm (0.86 lb-in) of torque when securing the MT80 to the
host.
3. Use safe ESD practices when handling and mounting the MT80.

3-3. .Window Window Material Materials s
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

15
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 <1mm
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.

3-5. Window Window Care Care
In the aspect of window, the performance of MT80 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.

The MT80 scan engine conforms to the following regulations:
1. Electromagnetic Compliance – CE EN55022, EN55024
2. Electromagnetic Interference – FCC Part15 Subpart B (Class B)
3. Photobiological Safety – IEC 62471 (Exempt Group)
