INTRODUCTION MT1 One-piece Compact 2D Scan Engine provides snappy scanning performance at a competitive cost and compact form factor. With its all-in-one design, MT1 2D scan engine can be easily integrated with specific applications such as access control, lottery kiosk and consumer electronics. The MT1 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. 1-1.

Pin Assignment (Back View of MT1) Contact points of connector are on the inside Pin# Definition I/O Description 1 GND ------------ Power and signal ground. 2 nTRIG Input High: Stop Scanning Low: Start Scanning Schematic Example Once nTRIG pin is pull low for more than 5ms, the scanning operation starts until a barcode is successfully decoded or the nTRIG pin is pull high. To proceed to the next scanning operation, pull high first and pull low again. A minimum of 50ms interval is recommended between two trigger signals. ___________________________________________________________________________________ 2 MT1 Scan Engine, Integration Guide, V1.1 Pin# Definition I/O Description Schematic Example 3 nRST Input 4 LED Output Keep level low for at If the pin is not in use, leave it unconnected. least 100us to reset the scan engine. When scanning is successful (Good Read), it outputs a high-level pulse, whose load capacity is limited and not enough to driver LED directly. A supporting LED drive circuit is required. 5 Buzzer Output Active High: it indicates the status of Power-Up or a successful barcode decode. PWM controlled signal can be used to drive an external buzzer for a successful barcode decode (Good Read). 6 EXT LED Output CTRL External LED illumination control signal.

USB VCP Interface ___________________________________________________________________________________ 8 MT1 Scan Engine, Integration Guide, V1.1 Interface Configuration Barcode: USB VCP 2-3. Operation Method 1. At power-up, the MT1 sends the Power-Up signals over Buzzer and LED pins as an indication that the MT1 enters Standby Mode and is ready for operation. 2. Once the MT1 triggered by either hardware or software method, MT1 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 MT1. 4. Upon a successful barcode decoded, the MT1 turns off the illumination LEDs, sending the Good Read signals over Buzzer and LED pins and transmitting the decoded data to the host. 2-4.

Connector Specification MT1 is built with a 13-pin pitch 0.3mm FPC connector. The recommended Model No. of 13-pin connector is FH35C-13S-0.3SHW(50) When the 13-pin to 12-pin FPC cable (shipped with MT1 by default) is used, the recommended Model No. of 12-pin pitch 0.5mm FPC connector on the host side is FH34SRJ-12S-0.5SH(50), with pin assignment below: Pin# Definition I/O Description 1 NC ------------ Floating 2 VCC ------------ 3.3V power supply. 3 GND ------------ Power and signal ground. 4 UART_TX Output UART TTL data output. 5 UART_RX Input UART TTL data input. 6 USB_D- Bidirectional USB D- signal 7 USB_D+ Bidirectional USB D+ signal 8 NC ------------ Floating 9 Buzzer Input Buzzer input 10 LED Input Good read LED input 11 nRST Output Reset signal output 12 nTRIG Output Trigger signal output ___________________________________________________________________________________ 10 MT1 Scan Engine, Integration Guide, V1.1 3. INSTALLATION 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. 3-1. Electrostatic Discharge Cautions 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. 3-2. Installation Recommendations 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. 4. Do not enclose the scan engine with thermal insulation material. Failure of heat dissipation may deteriorate the scan engine's performance. 3-3. Installation Orientation Two M1.4 screw holes (max depth 2mm) are available at the bottom of MT1. When the screw holes are facing downwards, MT1's appearance should be identical to above picture. ___________________________________________________________________________________ 11 MT1 Scan Engine, Integration Guide, V1.1 3-4. Window Materials 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 Spectral Transmission Thickness Coating Description 85% minimum from 635 to 690 nanometers < 1 mm 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. ___________________________________________________________________________________ 12 MT1 Scan Engine, Integration Guide, V1.1 3-5. Window Placement MT1 Side View The distance between window and front of MT1 should not exceed L=0.5mm The thickness of the window should not exceed 1mm 3-6. Window Size Horizontal field of view 43° Horizontal illumination area 55° Vertical field of view 32° Vertical illumination area 50° 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. 3-7. Window Care In the aspect of window, the performance of MT1 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. ___________________________________________________________________________________ 13 MT1 Scan Engine, Integration Guide, V1.1 4.
