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 interfaced panels with panel voltage 3.3V, 5V or 12V 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)

2. 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.

3. 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.

4. 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 28 for more information on connection.

5. 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.

6. 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.

7. 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.

8. 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.

9. 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 : Serial control via this interface port.

12. External panel power output : User for specific panel model.

13. 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.

• 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.

• 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.

• Refer to graphics modes table in specifications section for supported modes.

• Non-interlaced & interlaced video input is acceptable.

IMPORTANT: Please read the Application Notes section for more information.

APPLICATION NOTES FOR PR-1200/PR-2400

USING THE CONTROLLER WITHOUT BUTTONS ATTACHED

This is very straightforward:

• Firstly setup the controller/display system with the buttons. With controls attached and display system active make any
settings for colour, tint and image position as required then switch everything off.

• Remove the control switches, the 12-way (CNC1) cable.

• Use a jumper or similar to connect pins 1 & 2 on CNC1, this will fix the board On.

• Refer to inverter specifications for details as to fixing brightness to a desired level, this may require a resistor, an open

circuit or closed circuit depending on inverter.

Summary: On CNC1 the only pins that are used are for On/Off and Brightness (if controller mounted inverter is used). On
CNC1 the pins are for momentary type buttons so it doesn’t matter that no buttons are attached.

INVERTER CONNECTION

There are potentially 3 issues to consider with inverter connection:

• Power

• Enable

• Brightness

Please read the following sections for a guide to these issues.
Inverter Power: As per the table for CNB1 pin 1 is ground and pin 2 provides 12V/24V DC. This should be matched with the

inverter specification: see table.

CNB1

PIN DESCRIPTION

1 Ground
2 PR-1200 : +12VDC

PR-2400 : +24VDC

Remark: For higher power inverter, more current (for 12V/24V) can be taken from CNA1 pin 1.

Enable: This is a pin provided on some inverters for On/Off function and is used by this panel controller for VESA DPMS
compliance. If the inverter does not have an enable pin or the enable pin is not used then DPMS will not be operational. Pin 3
should be matched to the inverters specification for the ‘enable’ or ‘disable’ pin.

CNB1

PIN DESCRIPTION

3 Enable

Further, jumpers JB2 & JB3 should be set to match the inverters specification for the enable pin power and High or Low setting:
see table.

Ref

Purpose Note

JB2 Inverter enable voltage 1-2 H = 12V/24V, 2-3 H = 5V (Vcc), OPEN H = open collector
JB3 Inverter control 1-2 H = On, 2-3 L = On

Brightness: There are various methods for brightness control and it is important to consider the specifications for the inverter to
be used. Generally the situation is:

• Brightness can control by using a resistor or VR (Variable Resistor).

• Brightness controlled by adding a circuit such as PWM (Pulse Width Modulation).

• No adjustment of brightness is possible.

CNB1 pins 4 & 5 are available for connecting to an inverter or circuit where VR control is supported.

CNB1

PIN DESCRIPTION

4 VR WIP
5 VR A

This can then be matched with function controls connected to CNC1 pins 4 & 3 or 5: see table.

2 SW_ON Power button B
3 BVR_A Backlight Brightness VR pin A
4 BVR_WIP Backlight Brightness R pin WIP
5 BVR_B Backlight Brightness VR pin B (470 ohm resistor to +5V Vcc)

12 NC No connection

The VR for brightness depends on the inverter. The main power load for On/Off is handled by a relay on the controller.

Example for circuit design :

Signal description / Notes :

1) R1 : 470ohm on board

2) RPOT is an external potentiometer (in-line dip
style) that can be plugged directly into CNC1 pins
3,4,5. RPOT must be supplied / installed by user.

3) BVR_B : Voltage tapped from “top” of
potentiometer, the node of R1 and RPOT.

4) BVR_WIP : Voltage tapped from wiper arm of
RPOT.

5) BVR_A : Voltage tapped from “bottom” of
RPOT.

Note : BVR_A voltage is left floating on the
controller board. To use this circuit, you need
to tie this point to a potential (usually GND,
available at CNC1

p

in 6).

1.)Choose RPOT = 10K

2.) Tie BVR_A to GND

3.) Circuit analysis gives BVR_WIP as the
following (see Figure 1)

BVR_WIP = 5 x (Rbc/10.47)
where BVR_WIP is in Volts.

And Rbc is the resistance from the wiper arm
to bottom of pot in Kohms.

To evaluate, plug in different values of Rbc :

Rbc BVR_WIP

0 0 V

2.5 K 1.2 V
5 K 2.4 V

7.5 K 3.6 V

10 K 4.8 V
So this circuit could provide Brightness
adjust voltage ranging from 0V to 5V.

TROUBLESHOOTING

General

A general guide to troubleshooting a flat panel display system it is worth considering the system as separate elements, such as:

 Controller (jumpers, PC settings)
 Panel (controller, cabling, connection, panel, PC settings)
 Backlight (inverter, cabling, backlight tubes)
 Cabling
 Computer system (display settings, operating system)

Through step by step cross checking with instruction manuals and a process of elimination to isolate the problem it is usually
possible to clearly identify the problem area.

No image:

 If the panel backlight is not working it may still be possible to just see some image on the display.
 A lack of image is most likely to be caused by incorrect connection, lack of power, failure to provide a signal or incorrect

graphic card settings.

Image position:

If it is impossible to position the image correctly, i.e. the image adjustment controls will not move the image far enough, then
test using another graphics card. This situation can occur with a custom graphics card that is not close to standard timings or if
something is in the graphics line that may be affecting the signal such as a signal splitter (please note that normally a signal
splitter will not have any adverse effect).

Image appearance:

 A faulty panel can have blank lines, failed sections, flickering or flashing display
 Incorrect graphics card refresh rate, resolution or interlaced mode will probably cause the image to be the wrong size, to

scroll, flicker badly or possibly even no image.

 Incorrect jumper settings on the controller may cause everything from total failure to incorrect image. CAUTION: Do not set

the panel power input incorrectly.

 Sparkling on the display: faulty panel signal cable.

Backlight:

Items to check include: Power input, Controls, Inverter and Tubes generally in this order.
If half the screen is dimmer than the other half:

 Check cabling for the inverter.
 For a specific backlight tube check the AC pins orientation (CAUTION: Never reverse any DC power pins).

Also:
 If adjusting brightness control has no effect the chances are that the VR rating or method of adjusting brightness is not

compatible or correctly connected to the inverter.

 If system does not power down when there is a loss of signal

Continued failure:

If unit after unit keeps failing consider and investigate whether you are short circuiting the equipment or doing something else
seriously wrong.

Generally after common sense issues have been resolved we recommend step by step substitution of known working parts to
isolate the problem.

Remark :
The controller has been designed to take a very wide range of input signals however to optimize the PC’s graphics
performance we recommend choosing 60Hz vertical refresh rate. To support on higher refresh rate over 60Hz, the
LCD panel may not support.

Appendix IV – Auto Color Gain

The Auto Color Gain function is supported in the ARGB mode only and is designed to
calibrate the controller to the incoming video signal. In order to calibrate correctly, the display must be
displaying an image containing both black and white data (see illustration below) when the function is
used. The internal processor of the video controller chip will then execute a process to adjust the
relative values of the RGB signals to achieve the best performance. The parameters of the corrected
RGB values are then stored in the controller and are unaffected by the Reset Factory Defaults
function.

The reference pattern can be downloaded at :

http://www.digitalview.com/support/downloads/TestPattern_1280.BMP

This reference pattern is for 1280x1024 resolution and it needs to set your ARGB input source to
1280x1024 resolution before performing the Auto Color Gain function. The position of the black
vertical bar in the pattern at the right side is important. It will affect the calibration result if you are
setting the ARGB input to other resolution.

Warning

- If the Auto Color Gain is executed without an appropriate image being displayed, then the
process will set incorrect values and the display colors will be distorted. If this occurs, then it can
either be corrected by performing the process correctly or if this is not possible then the Reset Color
Gain function can be used. This function will reset the stored RGB values to a set of approximate
values.

Appendix VI – Function description for de-interlacing mode AFM, TNR, MADI, DCDi

AFM = Auto Film Mode :
It is a frame based method which used for the input ODD and EVEN fields have a fixed relation
between each other, such as static image, 3:2 pull down mode.
If two fields are correctly merged, it can get the best quality. But if it merges two wrong fields, it will
have artifact and get the worst quality.

TNR = Temporal Noise Reduction :
It is a frame based method which assume field to field have a fixed relationship.
If the object moving too fast, it will have image artifact and get worst quality.

MADI = Motion adaptive de-interlacing :
It is a pixel based method which used for the input fields have no fixed relation between them
If the object moving very too fast, it will get worst quality.

DCDi = Directional Correlation Deinterlacing :
It is a digital enhancement method developed by Faroudja. DCDi technology is primarily used for
improving the image quality of low resolution images. This is done by deinterlacing the image and
blending rough edges occurring in diagonal lines.
