This controller is designed for monitor and custom display projects using 1024x768, 800x600, 640x480 resolution TFT LCD’s
support. The BIOS need to change to fit for XGA, SVGA, VGA panel respectively. TFT panels with a XGA, SVGA, VGA signal
input. The following provides some guidelines for installation and preparation of finished display solution.
ASSEMBLY NOTES
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.
1. LCD Panel: This controller is designed for typical TFT panels with 5V or 3.3V TTL or LVDS interface. For LVDS
interface panel a separate add-on board is required. 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)
NOTE: This controller supports up to 8-bit per colour, for panels of lower bits (eg 3 x 3 bit, 3 x 4 bit etc), connection of the
panel signal high value should correspond to the controllers highest bit. For example for a 3 x 3 bit panel R2 on the panel
should connect to R7 on the controller, in this case R0~4 on the controller will not be connected. For a 3 x 6 bit panel R5
on the panel should be connected to R7 on the controller. For a 3 x 8 bit panel R7 on the panel should be connected to
R7 on the controller. Same for G & B.
2. Controller card: Handle the controller card with care as static charge may damage electronic components.
3. LCD connector board: Different makes and models of LCD panel require different panel signal connectors and
different pin assignments. The connector board may not necessary for some Digital View cables that direct plug to the
LCD panel.
4. LCD 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 Application notes 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 the inverter. Using wrong cable pin out may damage the inverter.
7. 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 (4 momentary buttons).
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. 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.
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 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.
