9. Controller status LED (Optional) : This LED indicates the controller status. 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.
Controller LED status (LED1) :
State LED color
No signal & backlight off RED
No signal & backlight on ORANGE
With signal & backlight on GREEN
10. IR sensor: It is an optional part only, can be unconnected if not using IR remote control.
11. Audio add-on board P/N 416040010-3: 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.
CAUTION : The Audio Add-on Board P/N 416940020-3 can only operate with 12VDC power
input environment.
12. RS-232 control interface : The RS-232 protocols shown in Appendix II.
13. S-Video 1 / Composite 1 / Composite 2 : AV cables: Standard Composite video or S-video
cables can be used. Reasonable quality cable should be used to avoid image quality
degradation.
14. Alternate video input : Support alternate composite video 1 / S-Video 1 input on CNV1
connector.
15. Auxiliary video input : This port provides Composite video 2-4 or Composite video 2 & S-video 2
(JP2 jumper selectable). The video input selection can be switched via OSD menu or RS-232
command (0x98).

16. 12V / 24VDC power input :
• Power Input: 12V DC / 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.
24VDC input is required when the panel output voltage is 18VDC. Please refer to page 11-12 for
proper jumper settings.
• 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 / 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.
• 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:
