If the MT82W (with hot plug) is plugged or unplugged while the cable is live, the electronic components of the MT82W may be damaged. Make sure that the power is turned off while the cable is being inserted. Poor power connections, or short-closed power-off operations, or excessive voltage-dropping pulses may cause the MT82W to be in a stable, normal state of operation and maintain a stable power input. The MT82W does not actively control the power supply itself. In the application, the power can be cut off to stop the operation to achieve the lowest consumption. MT82W is less than 4s from power on to completion. After turning off the power, it is recommended to allow the power input to be turned on again after more than 500ms. ___________________________________________________________________________________ 5 MT82W Scan Engine, Integration Guide, V1.1 1-4. Ripple Noise Since the power input of the MT82W is directly supplied to the image sensor and the decoder chip, a low ripple noise power input is required to ensure stable operation. It is recommended to control the ripple noise to within 50mV (peak-to-peak), at least not to exceed 100mV.(peak-to-peak). ___________________________________________________________________________________ 6 MT82W Scan Engine, Integration Guide, V1.1 2.

Operation Method 1. At power-up, the MT82W sends the Power-Up signals over Buzzer and LED pins as an indication that the MT82W enters Standby Mode and is ready for operation. 2. Once the MT82W triggered by either hardware or software method, MT82W 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 MT82W. 4. Upon a successful barcode decoded, the MT82W 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.

It uses a ZIF 12 PIN lower contact socket and is connected to the peripheral (host) with a flexible cable. The lower icon shows the size of the socket (unit: mm). ___________________________________________________________________________________ 10 MT82W 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 When the MT82W is properly placed or installed, its front view looks like the ___________________________________________________________________________________ 11 MT82W Scan Engine, Integration Guide, V1.1 picture below. In the middle is the lens, the two sides are aimed, the upper is the decoding circuit board, and the screw mounting holes are below. At this time, the relative orientation of the image captured by the MT82W correctly corresponds to its orientation. 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 ___________________________________________________________________________________ 12 MT82W Scan Engine, Integration Guide, V1.1 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 Placement The window placement distance is obtained by measuring the distance between the MT82W front plane and the farthest plane of the window. In order to ensure good reading performance, the vertical distance between the far end face of the window and the front end face of the MT82W is no more than 3mm, and the vertical distance between the near end face of the window and the front end face of the MT82W is not more than 2mm. If the window needs to be tilted, the distance requirement is the same as the parallel installation. The tilt angle should ensure that there are no various beams that can be reflected into the lens to ensure read performance. 3-6. Window Care In the aspect of window, the performance of MT82W 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. 3-7. Ambient Light The MT82W can achieve better performance in the presence of ambient light, and can be well adapted to the fluorescent flicker of 50~60Hz common lighting AC, but in high frequency pulse flash environment, performance may be reduced due to interference. 3-8. Safe Use The MT82W uses light-emitting diodes (LEDs) to form the aiming indication pattern. The wavelength range of the light wave generated by the LED under normal use is ___________________________________________________________________________________ 13 MT82W Scan Engine, Integration Guide, V1.1 safe, but it should still avoid direct-viewing the LED or directing the beam to the human eye during use to avoid causing discomfort. 4. REGULATIONS The MT82W scan engine conforms to the following regulations: 1. Electromagnetic Compliance TBA 2. Electromagnetic Interference TBA 3. Photobiological Safety TBA 4.
