The following provides some guidelines for installation and preparation of a finished display solution. Preparation: Before proceeding it is important to familiarize yourself with the parts making up the system and the various connectors, mounting holes and general layout of the controller. As much as possible connectors have been labelled. Guides to connectors and mounting holes are shown in the following relevant sections. 1. LCD Panel: This controller is designed for typical LVDS or TTL inteface panels with panel voltage 3.3V, 5V or 12V, External for 12V~18V interface. Due to the variation between manufacturers of panels signal timing and other panel characteristics, factory setup and confirmation should be obtained before connecting to a panel. (NOTE: Check panel power jumper settings before connection) 2. Controller: Handle the controller with care as static charge may damage electronic components. Make sure correct jumper and dip switches settings to match the target LCD panel. 3. LCD signal cable (LVDS panel): In order to provide a clean signal it is recommended that LVDS signal cables are no longer than 46cm (18 inches). If those wire cabling is utilized these can be made into a harness with cable ties. Care should be taken when placing the cables to avoid signal interference. Additionally it may be necessary in some systems to add ferrite cores to the cable to minimise signal noise. 4. LCD signal cable (TTL panel): In order to provide a clean signal it is recommended that LCD signal cables should not longer than 33cm (13 inches). If loose wire cabling is utilised these can be made into a harness with cable ties. Care should be taken when placing the cables to avoid signal interference. Additionally it may be necessary in some systems to add ferrite cores to the cables to minimise signal noise. 5. Inverter: This will be required for the backlight of an LCD, some LCD panels have an inverter built in. As LCD panels may have 1 or more backlight tubes and the power requirements for different panel backlights may vary it is important to match the inverter in order to obtain optimum performance. See Application notes page 18 for more information on connection. 6. Inverter Cables: Different inverter models require different cables and different pin assignment. Make sure correct cable pin out to match inverter. Using wrong cable pin out may damage the inverter. 7. Function Controls: The following section discusses the controls required and the section on connectors provides the detail. The controls are minimal: On/Off, Backlight Brightness (depends on inverter), OSD (5 momentary buttons) analog VR type or (8 momentary buttons) digital type. The 8 momentary buttons OSD switch mount P/N 416100520-3 or OSD membrane interface P/N 416100120-3 must be used when 24VDC input. 8. Function controls cable: The cables to the function switches should be of suitable quality and length so that impedance does not affect performance. Generally lengths up to 1 meter (3 feet) should be acceptable. 9. Status LED: The pin direction of the LED should be corrected for right colour indication. Red colour stands for standby. Green colours stands for signal on. The status LED is an optional part only, can be unconnected. 10. IR sensor: It is an optional part only, can be unconnected if not using IR remote control. 11. RS-232 control interface. 12. Audio add-on board P/N 416040010-3: Provide the interface for the audio add-on board to be connected. The audio addon board gives the audio input and output signal connection. But the volume cannot be controlled by the OSD menu on the controller. It is an optional part only, can be unconnected if not using audio. CAUTION : The Audio Add-on Board P/N 416940020-3 is only operate under 12VDC power input environment. 13. VGA Input Cable: As this may affect regulatory emission test results and the quality of the signal to the controller a suitably shielded cable should be utilized. 14. DVI-D input cable : Plug the DVI cable to the connector P2 on the controller board. 15. Composite video input : Standard Composite cables can be used. Reasonable quality cable should be used to avoid image quality degradation. 16. S-Video input : Standard Composite or S-video cables can be used. Reasonable quality cable should be used to avoid image quality degradation. 17. Component video input : Plug the component video input cable P/N 426000600 on CNV2 connector 18. Alternate composite and S-video input : Plug the video input cable P/N 426000500 on CNV1 connector 19. HD component video input : Plug the YPbPr signal input on CN6 connector. You can consider to use HD component video cable P/N 42603300-3 (YPbPr to DB15 connector) / P/N 426004100-3 (YPbPr to RCA jacks). 4 20. Interface for connecting to HD-SDI adaptor board HD-SDI (1-in-1-out) adaptor board, Kit number P/N 546013410-3 includes : HD-1000 adaptor (1-in-1-out) P/N 416013410-3 Ribbon cable P/N 426171120-3, 180mm HD-SDI (2-in-2-out) adaptor board, Kit number P/N 546013310-3 includes : HD-2000 adaptor (2-in-2-out) P/N 416013310-3 Ribbon cable P/N 426171120-3, 180mm 21. Power Input: 12V/24VDC is required, this should be a regulated supply. The power rating is depending on the panel and inverter used. Normally, power supply with 3.5Amp current output should enough for most of 4x CCFT panels. Although the controller provides power regulation for the LCD power this does not relate to the power supplied to the backlight inverter. If an unregulated power supply is provided to an inverter any fluctuations in power may affect operation, performance and lifetime of the inverter and or backlight tubes. 22. External panel power input : Allow to supply external power to the panel separately for max 3.3V (7A) or 5V (7A) or 12V (5A) or 18V (3.5A) via PP4 power input connector. 23. Auxiliary video input : This port provides Composite video 1 & 2, S-video 1 & 2, SD component 1 & 2. The video input selection can be switched via RS-232 command (0x98). 24. Auxiliary +5VDC output : 2 ways connector provides +5VDC output. 25. Ambient light sensor connection : 3 ways connector provides interface for ambient light sensor connection. 26. Backlight status input : 2 ways connector provides interface for connection with panel which support the panel whith backlight status monitoring function. * Power output: Note the controller has an overall 3Amp current limit and the current available from the auxiliary power output will be dependent on the power input and other system requirements. * Power Safety: Note that although only 12V / 24VDC is required as `power-in' a backlight inverter for panel backlighting produces significantly higher voltages (the inverter does not connect to the ground plane). We strongly advise appropriate insulation for all circuitry. * EMI: Shielding will be required for passing certain regulatory emissions tests. Also the choice of external Controller to PC signal cable can affect the result. * Ground: The various PCB mounting holes are connected to the ground plane. * Servicing: The board is not user serviceable or repairable. Warranty does not cover user error in connecting up to the controller and is invalidated by unauthorized modification or repairs. * Controller Mounting: It is recommended that a clearance of at least 10mm is provided above and 5mm below the controller when mounted. Additionally consideration should be given to: * Electrical insulation. * Grounding. * EMI shielding. * Cable management. Note: It is important to keep panel signal cables apart from the inverter & backlight cables to prevent signal interference. * Heat & Ventilation: Heat generated from other sources, for example the backlight of a very high brightness panel may generate significant heat which could adversely affect the controller. * Other issues that may affect safety or performance. * PC Graphics Output: A few guidelines: * Signal quality is very important, if there is noise or instability in the PC graphics output this may result in visible noise on the display. * Refer to graphics modes table in specifications section for supported modes. * Non-interlaced & interlaced video input is acceptable. IMPORTANT: Please read the Application Notes section for more information. 5 CONNECTION & OPERATION CAUTION: Never connect or disconnect parts of the display system when the system is powered up as this may cause serious damage. CONNECTION Connection and usage is quite straight forward (it is useful to have the relevant connection diagram available at this time): 1. LCD panel & Inverter: Connect the inverter (if it is not built-in the panel) to the CCFT lead connector of the LCD panel. 2. TTL type panels: Plug the signal cables direct to CN2, CN3 and CN4 (CN4 will not be used for 3x6-bit panel) on the controller board. Plug the other end of cables to the LCD connector board (if connector board is required, otherwise the signal can be direct plug to the LCD panel connector). Then plug the board connector to the LCD panel connector. LVDS type panels: The controller board has the built-in LVDS transmitter driver. Plug the LVDS cable to J3. Insert the panel end of the cable the LCD panel connector. 3. Inverter & Controller: Plug the inverter cable to CNB1 and CNA1 (if necessary). Plug another end to the connector on the inverter. 4.

We recommend clearances of: * 5mm from bottom of PCB - if mounting on a metal plate we also recommend a layer of suitable insulation material is added to the mounting plate surface. * 10mm above the components * 3~5mm around the edges Any of the holes shown above can be used for mounting the PCB, they are 3.2mm in diameter. CAUTION: Ensure adequate insulation is provided for all areas of the PCB with special attention to high voltage parts such as the inverter. 23 APPLICATION NOTES USING THE CONTROLLER WITHOUT BUTTONS ATTACHED This is very straightforward: * Firstly setup the controller/display system with the buttons. With controls attached and display system active make any settings for colour, tint and image position as required then switch everything off. * Remove the control switches, the 12-way (CNC1) cable. * Use a jumper or similar to connect pins 1 & 2 on CNC1, this will fix the board On. * Refer to inverter specifications for details as to fixing brightness to a desired level, this may require a resistor, an open circuit or closed circuit depending on inverter. Summary: On CNC1 the only pins that are used are for On/Off and Brightness (if controller mounted inverter is used). On CNC1 the pins are for momentary type buttons so it doesn't matter that no buttons are attached. INVERTER CONNECTION There are potentially 3 issues to consider with inverter connection: * Power * Enable * Brightness Please read the following sections for a guide to these issues. Inverter Power: As per the table for CNB1 pin 1 is ground and pin 2 provides 12V/24V DC. This should be matched with the inverter specification: see table. CNB1 PIN DESCRIPTION 1 Ground 2 +12V/+24VDC Remark: For higher power inverter, more current (for 12V/24V) can be taken from CNA1 pin 1. Enable: This is a pin provided on some inverters for On/Off function and is used by this panel controller for VESA DPMS compliance. If the inverter does not have an enable pin or the enable pin is not used then DPMS will not be operational. Pin 3 should be matched to the inverters specification for the `enable' or `disable' pin. CNB1 PIN 3 DESCRIPTION Enable Further, jumpers JB2 & JB3 should be set to match the inverters specification for the enable pin power and High or Low setting: see table. Ref JB2 JB3 Purpose Inverter enable voltage Inverter control Note 1-2 H = 12V/24V, 2-3 H = 5V (Vcc), OPEN H = open collector 1-2 H = On, 2-3 L = On Brightness: There are various methods for brightness control and it is important to consider the specifications for the inverter to be used. Generally the situation is: * Brightness can controlled by using a resistor or VR (Variable Resistor). * Brightness controlled by adding a circuit such as PWM (Pulse Width Modulation). * No adjustment of brightness is possible. CNB1 pins 4 & 5 are available for connecting to an inverter or circuit where VR control is supported. CNB1 PIN DESCRIPTION 4 VR WIP 5 VR A This can then be matched with function controls connected to CNC1 pins 4 & 3 or 5: see table. CNC1 PIN DESCRIPTION 3 VR A 4 VR WIP 5 VR B 24 Design Guideline for making VR circuitry : Signal description / Notes : 1) R1 : 470ohm on board 2) RPOT is an external potentiometer (in-line dip style) that can be plugged directly into CNC1 pins 3,4,5. RPOT must be supplied / installed by user. 3) BVR_B : Voltage tapped from "top" of potentiometer, the node of R1 and RPOT. 4) BVR_WIP : Voltage tapped from wiper arm of RPOT. 5) BVR_A : Voltage tapped from "bottom" of RPOT. Note : BVR_A voltage is left floating on the controller board. To use this circuit, you need to tie this point to a potential (usually GND, available at CNC1 pin 6).

The main power load for On/Off is handled by a relay on the controller. Example for circuit design : 1.)Choose RPOT = 10K 2.) Tie BVR_A to GND 3.) Circuit analysis gives BVR_WIP as the following (see Figure 1) BVR_WIP = 5 x (Rbc/10.47) where BVR_WIP is in Volts. And Rbc is the resistance from the wiper arm to bottom of pot in Kohms. To evaluate, plug in different values of Rbc : Rbc 0 2.5 K 5K 7.5 K 10 K BVR_WIP 0V 1.2 V 2.4 V 3.6 V 4.8 V So this circuit could provide Brightness adjust voltage ranging from 0V to 5V. 25 TROUBLESHOOTING General A general guide to troubleshooting a flat panel display system it is worth considering the system as separate elements, such as: 3/4 Controller (jumpers, PC settings) 3/4 Panel (controller, cabling, connection, panel, PC settings) 3/4 Backlight (inverter, cabling, backlight tubes) 3/4 Cabling 3/4 Computer system (display settings, operating system) Through step by step cross checking with instruction manuals and a process of elimination to isolate the problem it is usually possible to clearly identify the problem area. No image: 3/4 If the panel backlight is not working it may still be possible to just see some image on the display. 3/4 A lack of image is most likely to be caused by incorrect connection, lack of power, failure to provide a signal or incorrect graphic card settings. Image position: If it is impossible to position the image correctly, ie the image adjustment controls will not move the image far enough, then test using another graphics card. This situation can occur with a custom graphics card that is not close to standard timings or if something is in the graphics line that may be affecting the signal such as a signal splitter (please note that normally a signal splitter will not have any adverse effect). Image appearance: 3/4 A faulty panel can have blank lines, failed sections, flickering or flashing display 3/4 Incorrect graphics card refresh rate, resolution or interlaced mode will probably cause the image to be the wrong size, to scroll, flicker badly or possibly even no image. 3/4 Incorrect jumper settings on the controller may cause everything from total failure to incorrect image. CAUTION: Do not set the panel power input incorrectly. 3/4 Sparkling on the display: faulty panel signal cable. Backlight: Items to check include: Power input, Controls, Inverter and Tubes generally in this order. If half the screen is dimmer than the other half: 3/4 Check cabling for the inverter. 3/4 For a specific backlight tube check the AC pins orientation (CAUTION: Never reverse any DC power pins). Also: 3/4 If adjusting brightness control has no effect the chances are that the VR rating or method of adjusting brightness is not compatible or correctly connected to the inverter. 3/4 If system does not power down when there is a loss of signal Continued failure: If unit after unit keeps failing consider and investigate whether you are short circuiting the equipment or doing something else seriously wrong. Generally after common sense issues have been resolved we recommend step by step substitution of known working parts to isolate the problem. 26 SPECIFICATIONS Panel compatibility No. of colours Panel power Panel signal Vertical refresh rate Display clock maximum ADC clock maximum DVI differential input clock maximum Graphics formats Graphics auto mode detect Standard input at source (analog RGB) Video formats Video inputs Functions display OSD menu functions OSD menu controls available Control interface Settings memory PC Connectivity Controller dimensions Power consumption Power load maximum Input voltage Power protection DC Power handling Storage temperature limits Operating temperature limits Compatible with 1920x1200, 1920x1080, 1680x1050, 1600x1200, 1440x900 1366x768, 1280x1024, 1024x768, 800x600 & 640x480 resolutions of TFT LCD panels.

Appendix III - Mapping definition * Definition of Mapping A : 40 * Definition of Mapping B : 41 Appendix IV - Auto Color Gain The Auto Color Gain function is supported in the ARGB mode only and is designed to calibrate the controller to the incoming video signal. In order to calibrate correctly, the display must be displaying an image containing both black and white data (see illustration below) when the function is used. The internal processor of the video controller chip will then execute a process to adjust the relative values of the RGB signals to achieve the best performance. The parameters of the corrected RGB values are then stored in the controller and are unaffected by the Reset Factory Defaults function. Warning - If the Auto Color Gain is executed without an appropriate image being displayed, then the process will set incorrect values and the display colors will be distorted. If this occurs, then it can either be corrected by performing the process correctly or if this is not possible then the Reset Color Gain function can be used. This function will reset the stored RGB values to a set of approximate values. 42 WARRANTY The products are warranted against defects in workmanship and material for a period of three (3) year from the date of purchase provided no modifications are made to it and it is operated under normal conditions and in compliance with the instruction manual.
