Product Warranty (2 years)

Advantech warrants to you, the original purchaser, that each of its products will be free from defects in materials and workmanship for two years from the date of purchase.
This warranty does not apply to any products which have been repaired or altered by persons other than repair personnel authorized by Advantech, or which have been subject to misuse, abuse, accident or improper installation. Advantech assumes no liability under the terms of this warranty as a consequence of such events.
Because of Advantech’s high quality-control standards and rigorous testing, most of our customers never need to use our repair service. If an Advantech product is defective, it will be repaired or replaced at no charge during the warranty period. For outof-warranty repairs, you will be billed according to the cost of replacement materials,
service time and freight. Please consult your dealer for more details.
If you think you have a defective product, follow these steps:

1. Collect all the information about the problem encountered. (For example, CPU speed, Advantech products used, other hardware and software used, etc.) Note anything abnormal and list any onscreen messages you get when the problem occurs.
2. Call your dealer and describe the problem. Please have your manual, product, and any helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA (return merchandise authorization) number from your dealer. This allows us to process your return more quickly.
4. Carefully pack the defective product, a fully-completed Repair and Replacement Order Card and a photocopy proof of purchase date (such as your sales receipt) in a shippable container. A product returned without proof of the purchase date is not eligible for warranty service.
5. Write the RMA number visibly on the outside of the package and ship it prepaid to your dealer.

Warnings, Cautions, and Notes

Warning! Warnings indicate conditions, which if not observed, can cause personal injury!

Caution! Cautions are included to help you avoid damaging hardware or losing data. e.g.

Power ON/OFF Sequence

VDD power and lamp on/off sequence is as follows. Interface signals are also shown in the chart. Signals from any system shall be Hi-Z state or low level when VDD is off.

The above on/off sequence should be applied to avoid abnormal function in the display. Please make sure to turn off the power when you plug the cable into the input connector or pull the cable out of the connector.

Note 1: The supply voltage of the external system for the module input should be the same as the definition of VDD
Note 2: Apply the lamp voltage within the LCD operation range. When the back-light turns on before the LCD operation or the LCD turns off before the back-light turns off, the display may momentarily become white.
Note 3: In case of VDD = off level, please keep the level of input signal on the low or keep a high impedance.
Note 4: Interface signal shall not be kept at high impedance when the power is on.

The above on/off sequence should be applied to avoid abnormal function in the display. Please make sure to turn off the power when you plug the cable into the input connector or pull the cable out of the connector.

Mounting Notes

Mounting

• The gasket of the touch panel must be designed for the outside of the viewable area to avoid pressing on the touch panel accidentally and the enclosure must be designed with enough clearance from the panel surface. To avoid pressing errors on the touch panel, please allow space between the surface of the panel and the bezel.
• We recommended elastic type materials.
• The edge of the touch panel is conductive. Don’t touch it with metal after mounting.
• Please take notice of grounding while mounting the touch screen, otherwise interference may cause unstable performance.
• Please do not pull on the flex tail during assembly. Do not bend at 90 degrees and each bend angle should be no less than R=5m/m
• During assembly, the touch panel must be securely affixed onto the LCD panel to prevent displacement of the touch panel due to outside force pressing on touch screen or bezel/case.

Caution
Installing and Assembling

• Do not use excessive force or strain to the panel or tail.
• Gasket or cushion pads around the edge of the panel may segregate water and/ or dust contamination.
• Maintain a minimal 5R when bending the tail to prevent dead folds or fold marks.
• Flaws in customer module design may cause functionality issues after assembly.

Operating

• Touch the panel with your finger or stylus only to test normal operation. Any sharp edged or hard objects should not be used.
• Operate the panel in a steady environment. Abrupt variation on temperature and humidity may cause malfunctions to the panel.
• Avoid applying excessive activation force or sudden impact on the panel surface.
• Avoid high voltages and / or static charge.

Others

• Keep the panel surface clean. Prevent any kind of adhesive or tape applied onto the touch surface.

  Touch Controller

Touch Controller Characteristics
EETI EXC3132 is a MCU based projected capacitive touch screen controller designed for commercial and industrial applications. EXC3132 controller supports high voltage driving signal to achieve high SNR and better wideband interference susceptibility.
EXC3132 provides different working frequencies to avoid narrow band interference. With high voltage driving and different working frequencies, EXC3132 provides excellent interference susceptibility performance. EXC3132 provides an excellent solution for not only finger operation but also with gloves, thicker glass, etc. applications.

Handling Precautions

A.1 Handling Precautions

The optical characteristics are measured under stable conditions at 25°C (Room Temperature)

1. Since front polarizer is easily damaged, pay attention not to scratch it.
2. Be sure to turn off power supply when inserting or disconnecting from input connector.
3. Wipe off water drops immediately. Long contact with water may cause discoloration or spots.
4. When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
5. Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface.
6. Since CMOS LSI is used in this module, take care of static electricity and insure human earth when handling.
7. Do not open or modify the Module Assembly.
8. Do not press the reflector sheet at the back of the module to any directions.
9. In case if a Module has to be put back into the packing container slot after once it was taken out from the container, please press at the far ends of the LED light bar reflector edge softly. Otherwise the TFT Module may be damaged.
10. At the insertion or removal of the Signal Interface Connector, be sure not to rotate nor tilt the Interface Connector of the TFT Module.
11. After installation of the TFT Module into an enclosure, do not twist nor bend the TFT Module even momentary. At designing the enclosure, it should be taken into consideration that no bending/twisting forces are applied to the TFT Module from outside. Otherwise the TFT Module may be damaged.
12. A small amount of materials having no flammability grades have been used in the LCD module. The LCD module should be supplied by power complying with requirements of Limited Power Source (IEC60950 or UL1950), or be applied exempt of them.
