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 labeled. 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 interface TFT panels with panel voltage 3.3V or 5V or 12V or 18V LVDS interface. Due to the variation between manufacturers of 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 card: Handle the controller card with care as static charge may damage electronic components. 3. LVDS signal cable : In order to provide a clean signal it is recommended that LVDS signal cables are no longer than 46cm (18 inches). If loose 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 cables to minimize signal noise. 4. TTL signal cable: In order to provide a clean signal it is recommended that LCD signal cables are no longer than 33cm (13 inches). If loose 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 cables to minimize signal noise. 5. Inverter: This will be required for the backlight of an LCD, some LCD panels have an inverter built in. As panels may have 1 or more backlight tubes and the power requirements for different panel models backlights may vary it is important to match the inverter in order to obtain optimum performance. See page 15 for the Application notes "Inverter connection section for more informations. 6. Inverter Cables: Different inverter models require different cables and different pin assignment. Make sure correct cable pin out to match the 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. 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 metre (3 feet) should be acceptable. 9. DVI-D Input Cable : Plug the DVI cable to the connector P2 on the controller board 10. Analog 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. * Power Input: 12V / 24V DC is required, this should be a regulated supply. 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. 24VDC input is required when the panel output voltage is 18VDC. Please refer to page 10-11 for proper jumper settings. * Power Safety: Note that although only 12VDC / 24VDC is supplied 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. 3 * 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. 4 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. LVDS type panels: Plug the LVDS signal cable direct to CN1 (if necessary). Insert the panel end of the cable to the LCD panel connector. 3. TTL type panels: Plug the signal cables direct to CN2 or CN3. 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. 4. Inverter & Controller: Plug the inverter cable to CNB1 and CNA1 (if necessary). Plug another end to the connector on the inverter. 5. Function switch & Controller: Plug the OSD switch mount cable to CNC1 on the controller board and another to the OSD switch mount. 6. LED & Controller: Plug in a 3-way with dual colour LED to connector LED1 on the controller board. 7. Jumpers : Check all jumpers are set correctly. Details referring the connection diagram at http://www.digitalview.com/controllers/csg.php 8. Jumpers & Inverter & Panel voltage: Particularly pay attention to the settings of JA3, JA6, JB2, JB3. JB2 & JB3 are used for inverter control (read inverter specification and information on the jumper table to define the correct settings). JA3 & JA6 are used for panel voltage input (read panel specification and information on the jumper table to define the correct settings). 9. DVI cable : Plug the DVI cable to the connector P2 on the controller board. 10. VGA cable & Controller: Plug the VGA cable to the connector P1 on the controller board. 12.

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. 17 APPLICATION NOTES USING THE CONTROLLER WITHOUT BUTTONS ATTACHED This is very straightforward by following the steps below : * Firstly setup the controller/display system with the buttons. With controls attached and display system active make any settings for colour and image position as required then switch everything off. * Use a jumper to close JP6 jumper, 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. 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 DC12V/ 24V DC . This should be matched with the inverter specification: see table. CNB1 PIN DESCRIPTION 1 Ground 2 +12VDC / 24VDC Remark: For higher power inverter, more current (for 12V / 24V) can be taken from CNA1 pin 1. Maximum current drawn on CNA1 pin 1 and CNB1 pin 2 is 3A (24V) / 3A(12V) 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 (OSD switch mount) pins 3 & 4: see cable design below . 18 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. 19 TROUBLESHOOTING General A general guide to troubleshooting a flat panel display system it is worth considering the system as separate elements, such as: Controller (jumpers, PC settings) Panel (controller, cabling, connection, panel, PC settings) Backlight (inverter, cabling, backlight tubes) Cabling 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: If the panel backlight is not working it may still be possible to just see some image on the display. 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: A faulty panel can have blank lines, failed sections, flickering or flashing display 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. Incorrect jumper settings on the controller may cause everything from total failure to incorrect image. CAUTION: Do not set the panel power input incorrectly. 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: Check cabling for the inverter. For a specific backlight tube check the AC pins orientation (CAUTION: Never reverse any DC power pins). Also: 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. 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. 20 SPECIFICATIONS Panel compatibility No. of colours Vertical refresh rate Dot clock (pixel clock) maximum Graphics formats Standard input at source Controls available Control interface Settings memory Language OSD support VESA DPMS implementation Plug & Play Voltage output for LCD Input voltage Controller power consumption Controller dimensions Storage temperature limits Operating temperature limits 1366x768, 1280x1024, 1280x800, 1280x768, 1024 x 768, 1024x600, 800x600, 800x480, 640x480 or 480x234 resolution TFT LVDS or TTL LCD's support.

Appendix III - Mapping definition * Definition of Mapping A : 26 * Definition of Mapping B : 27 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. 28 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.
