ASSEMBLY NOTES

This controller is designed for monitor and custom display projects using 1920x1200 or 1920x1080 or 1920x480 or 1600x1200 or 1680x1050 or 1440x900 or 1366x768 or 1280 x 1024 or 1024 x 768 or 1024x600 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)

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. LCD signal cable (Single pixel TTL panel): In order to provide a clean signal it is recommended that LCD signal cables

should not 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 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 23 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 inverter. Using wrong cable pin out may damage the inverter.

7. 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.

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 meter (3 feet) should be acceptable.

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

11. RS-232 control interface : Firmware upgrade and serial control via this interface port.

12. Panel control signal : Use for specific panel model.

13. Audio add-on board P/N 416040010-3: Provide the interface for the audio add-on board to be connected. The audio add-

on board gives the audio input and output signal connection. But the volume cannot 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.

14. Ambient light sensor connection : 3 ways connector provides interface for ambient light sensor connection.

15. Interface for connecting to HD-SDI adaptor board

HD-2000 adaptor (2-in-2-out) P/N 416013310-3

Ribbon cable P/N 426171120-3, 180mm

16. Alternate video input for S-Video and composite video

17. HD/SD component video input : Plug the component video input signal on CNV2 connector



18. DVI-D input cable : Plug the DVI cable to the connector P3 on the controller board

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. S-video input : Standard S-Video cables can be used. Reasonable quality cable should be used to avoid image quality degradation.

21. Composite input : Composite video input cable with BNC connector can be used. Reasonable quality cable should be used to avoid image quality degradation.

22. 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).

23. 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.

24. 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.

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.

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.

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: insulation.

• Grounding.

• EMI

•

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.

CONTROLLER DIMENSIONS

Ready-made 3D Pro-E (SLDPRT) drawing files - Save time and effort for your system volumetric analysis design.

Includes jpg file previews. Please go to download at http://www.digitalview.com/drawing/SVH-1920+_-2X_3D_Drawing.zip

.

The maximum thickness of the controller is 20.65mm with or without video add-on board (measured from bottom of

PCB to top of components, including any underside components & leads). We recommend clearances of:

•

5mm from bottom of PCB - if mounting on a metal plate we also recommend a layer of suitable insulation material is added to the mounting plate surface.

•

10mm above the components

•

3~5mm around the edges

Any of the holes shown above can be used for mounting the PCB, they are 3.2mm in diameter.

CAUTION: Ensure adequate insulation is provided for all areas of the PCB with special attention to high voltage parts such as the inverter.



APPLICATION NOTES

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 +12V/+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

JB2

JB3

Purpose Note

Inverter enable voltage

Inverter control

1-2 H = 3.3V, 2-3 H = 5V (Vcc), OPEN H = open collector

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

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

CNC1

PIN DESCRIPTION



Design Guideline for making VR circuitry :

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 pin 6).

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 :

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

5 K

7.5 K

10 K

1.2 V

2.4 V

3.6 V

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 or Component video 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.

Support IR display addressing capability.

Start from SVH-1920+ P/N 417170023-3 version, it adds an IR remote function which can be made to select specific monitors with the following operation:

(a) Setup IR number on each monitor:

Assign new RS-232 command - “0xee”, “0x5A” for the user to set the two digits IR number (01~99) on each monitor via network.

Set IR ID “0xee”, “0x5A” nn | “+” | “-” |

“R” | “r” |

“?”

Set IR ID

Reset

Query

IR ID 01~99 nn = “0” “1” ~ “39” ”39”

Reset ID is 0 nn = “30” “30”

(b) Enable the IR function control for specific monitor :

Press "ATT" button and then type the "IR number" to enable controlling the target monitor. (e.g :

Press "ATT" button and type "08" to enable for controlling the IR number "08" monitor.)

The IR function control works same as normal after enabled the IR function.

(c) Disable the IR function control for specific monitor :

Two ways : i) When the target monitor is enable the IR control function, press and hold "ATTN" button and then type the "IR number" again to disable the IR control function.

OR ii) It will dis-connect the control automatically if no IR function input after 1 minute.

The user needs to press "ATT" button and then type the "IR number" to enable controlling the target monitor after timeout.

(d) Display IR number on screen :

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.
