ASSEMBLY NOTES

This controller is designed for monitor and custom display projects using 1920x1200 or 1920x1080 or 1600x1200 or

1680x1050 or 1440x900 or 1366x768 or 1280 x 1024 or 1024 x 768 or 800x600 or 640x480 resolution TFT panels with a VGA,

SVGA, WXGA, XGA, SXGA, UXGA or WUXGA signal input. 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.

LCD Panel:

This controller is designed for typical LVDS interfaced panels with panel voltage 3.3V, 5V, 12V or 18V,

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)

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.

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 minimize signal noise.

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 27 for more information on

connection.

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.

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.

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.

Status LED:

The pin direction of the LED should be corrected for right color indication. Red color stands for standby.

Green colors stands for signal on. The status LED is an optional part only, can be unconnected.

IR sensor:

It is an optional part only, can be unconnected if not using IR remote control. See Appendix V in details.

10. RS-232 control interface :

Firmware upgrade and serial control via this interface port.

11. Second RS-232 control interface :

This interface support controlled under “Programming mode” .

Press and hold “MENU” button on the OSD switch mount and turn on the controller to enter the “Programming mode”.

Choose “Set Uart 1 to CN1" Input Port shown below :

Set “Uart 1 to Ethernet Interface : Enable Ethernet network (J1) support and disable second RS-232 serial control (CN1)

support

Set “Uart 1 to CN1 : Enable second RS-232 serial control (CN1) support. Disable Ethernet network (J1) support

12. External panel power output

: User for specific panel model.

13. Panel control signal :

Use for specific panel model.

14. SPDIF Audio output :

This port support SPDIF audio output from the HDMI audio source inputted. (This port function is

not implemented yet)

15. Ambient light sensor connection :

3 ways connector provides interface for ambient light sensor connection by using Kit

70220-3.

16. Backlight status input :

2 ways connector provides interface for connection with the specific panel type which support the

panel with backlight status monitoring function.

17. DVI-D input cable :

Plug the DVI cable to the connector P2 on the controller board. This port is not supported when CN2

is connected.

18. HDMI input :

Plug the HDMI cable to the connector P3 on the controller board. This port is not supported when CN5 is

connected.

19. Analog RGB Input

: As this may affect regulatory emission test results and the quality of the signal to the controller a

suitably shielded cable should be utilized.

20. Component video input

: Plug the component video input cable P/N 426000600-3 on CNV2 connector

21. Alternate HDMI input :

This port gives alternate HDMI input support. This port is not support when P3 connector is

connected. It allows to connect HD-1000 / HD-2000 / HD-3000S for SDI input, see Appendix VIII for the connection setup.

22. Alternate DVI-D input :

This port gives alternate DVI-D input support. This port is not supported when P2 connector is

connected. It allows to connect HD-1000 / HD-2000 / HD-3000S for SDI input, see Appendix VIII for the connection setup.

23. AVD-1000 connection :

This port is for AVD-1000 video add on board connection. (Implemented start from V1.16.00.00

(U3) firmware or later version). See Appendix VIII for the connection setup.

24. Control over network connection :

This is a network device that allow to control RS-232 enable devices over a TCP/IP

based Ethernet and the Internet using a web browser. Please refer to Appendix VII in details.

25. Audio add-on board P/N 416940020-3:

The audio add-on board gives the audio input and output signal connection. It is

an optional part only, can be unconnected if not using audio. (This port function is not implemented yet)

CAUTION : The Audio Add-on Board P/N 416940020-3 can only operate with 12VDC power input environment.

26. Audio extend cable :

The audio extend cable P/N 426009700-3 designs for connection between audio add on board P/N

416940020-3 and the controller. It is an optional part only, can be unconnected if not using audio.

27. Power Input:

12VDC 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.

28. 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. Corresponding jumper setting of JA3, JA5 & JA6 are required for each

panel power input by referring to page 17.

•

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 12VDC 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.
