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.
1.
LCD Panel:
This controller is designed for typical LVDS or TTL interfaced 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)
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 25 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.
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.
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 colour indication. Red colour stands for standby.
Green colours 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.

12. External panel power output
: User for specific panel model.
13. Panel control signal :
Use for specific panel model.
14. Audio add-on board P/N 416940020-3:
Provide the interface for the audio add-on board P/N 416940020-3 to be
connected. The audio add-on board gives the audio input and output signal connection. The volume can 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.
15. Auxiliary +5VDC output :
2 ways connector provides +5VDC output.
16. Ambient light sensor connection :
3 ways connector provides interface for ambient light sensor connection by using Kit
70220-3.
17. Backlight status input :
2 ways connector provides interface for connection with the specific panel type which support the
panel with backlight status monitoring function.
18. HD / SD Component video input
: Plug the component video input cable P/N 426000600-3 on CNV2 connector
19. Composite & S-video input
: Standard Composite cables can be used. Reasonable quality cable should be used to avoid
image quality degradation.
20. HDMI audio output :
Support HDMI audio with stereo output.
The HDMI audio output can be connected to Audio add-on board P/N 416940020-3 by using the audio cable P/N
426451800-3 (310mm) connected between SVX-1920 (connector : CN10) and Audio add-on board P/N 416940020-3
(connector : CN2).
21. Alternate HDMI input :
This port gives alternate HDMI input support. This port is not support when P3 connector is
connected.
22. Alternate DVI input :
This port gives alternate DVI input support. This port is not supported when P2 connector is
connected.
23. Reserved :
No function, reserved for future development.
24. SPDIF Audio output :
This port support SPDIF audio output from the HDMI audio source inputted.
25. DVI-D input cable :
Plug the DVI cable to the connector P3 on the controller board.
26. HDMI input :
Plug the HDMI cable to the connector P2 on the controller board. This port is not supported when CN5 is
connected.
27. 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.
28. 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 VIII in details.
29. Auxiliary video input :
This port provides Composite video 1 & 2, S-video 1 & 2, Component 1 & 2. The video input
selection can be switched via RS-232 command (0x98) or OSD menu.
30. 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.
31. 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 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.
