ASSEMBLY NOTES

This controller is designed for monitor and custom display projects using 1280x1024, 1024x768, 800x600, 640x480 resolution TFT LVDS LCD’s support. The following provides some guidelines for installation and preparation of finished display solution.

Preparation Before proceeding it is important to familiarize yourself with the parts making up a 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. LCD Panel This controller is designed for typical LVDS interface TFT panels with panel voltage 3.3V or 5V or 12V, External for 12V~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 Controller card Handle the controller card with care as static charge may damage electronic components. 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. 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 13 for the Application notes “Inverter connection section for more informations. 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. Function Controls The following section ‘Operation’ discusses the controls required and the section ‘Connectors, jumpers & pinouts’ provides the detail. The controls are minimal for ease of use On/Off, Brightness depends on inverter , OSD 5 momentary buttons . 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. Status LED The pin direction of the LED should be corrected for right colour indication. Red colour stands for standby. Green colour stands for signal on. It is an optional part only, can be unconnected. 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 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. Power Safety Note that although only 12VDC 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 and power supply can affect the result. Ground The various PCB mounting holes are connected to the ground plane. Servicing The controller 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 interface. 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. Vertical refresh rate should be set to 60Hz preferable. Non-interlaced is required.

IMPORTANT Please read the Application Notes section for more information.

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 :

LCD panel & Inverter Connect the inverter if it is not built-in the panel to the CCFT lead connector of the LCD
panel.

LVDS type panels Plug the LVDS signal cable direct to CN5, CN6 / CN6A if necessary . Insert the panel end of the
cable the LCD panel connector.

Inverter & Controller Plug the inverter cable to CNB1 and CNA1 if necessary . Plug another end to the connector
on the inverter.

Function switch & Controller Plug the OSD switch mount cable to CNC1 on the controller board and another to the

OSD switch mount.

LED & Controller Plug in a 3-way with dual colour LED to connector LED1 on the controller board.

Jumpers Check all jumpers are set correctly. Details referring the connection diagram at

Jumpers & Inverter & Panel voltage Particularly pay attention to the settings of JA3, JB2, JB3, JA5. JB2 & JB3
are used for inverter control read inverter specification and information on the jumper table to define the correct
settings . JA3 & JA5 are used for panel voltage input read panel specification and information on the jumper table to
define the correct settings .

VGA cable & Controller Plug the VGA cable to the connector P1 on the controller board.

Power supply & Controller Plug the DC 12V power in to the connector PP1 or PP2/PP3
