ASSEMBLY NOTES
This controller is designed for monitor and custom display projects using 1366 x 768, 1280 x 1024 or 1280 x 768 or 1024 x 768
or 800x600 or 640x480 resolution TFT panels with a VGA, SVGA, XGA, SXGA 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 interface TFT panels with panel voltage 3.3V or 5V or 12V,
External for 12V~18V LVDS interface. Due to the variation between manufacturers of 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 card: Handle the controller card with care as static charge may damage electronic components.
3. LVDS signal cable : In order to provide a clean signal it is recommended that LVDS signal cables are no longer than
46cm (18 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.
4. TTL signal cable: In order to provide a clean signal it is recommended that LCD signal cables are no 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 panels may have
1 or more backlight tubes and the power requirements for different panel models backlights may vary it is important to
match the inverter in order to obtain optimum performance. See page 15 for the Application notes “Inverter connection
section for more informations.
6. Inverter Cables: Different inverter models require different cables and different pin assignment. Make sure correct cable
pin out to match the 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.
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 metre (3 feet) should be acceptable.
9. DVI-D Input Cable : Plug the DVI cable to the connector P2 on the controller board
10. Analog VGA Input Cable: As this may affect regulatory emission test results and the quality of the signal to the controller,
a suitably shielded cable should be utilized.
•Power Input: 12V DC is required, this should be a regulated supply. 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.
•Power Safety: Note that although only 12VDC is supplied 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.
•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.

CONNECTION & OPERATION
CAUTION: Never connect or disconnect parts of the display system when the system is powered up as this may cause serious
damage.
CONNECTION
Connection and usage is quite straight forward (it is useful to have the relevant connection diagram available at this time):
1. LCD panel & Inverter: Connect the inverter (if it is not built-in the panel) to the CCFT lead connector of the LCD
panel.
2. LVDS type panels:Plug the LVDS signal cable direct to CN1 (if necessary). Insert the panel end of the cable to the
LCD panel connector.
3. TTL type panels: Plug the signal cables direct to CN2 or CN3. Plug the other end of cables to the LCD connector
board (if connector board is required, otherwise the signal can be direct plug to the LCD panel
connector). Then plug the board connector to the LCD panel connector.
4. Inverter & Controller: Plug the inverter cable to CNB1 and CNA1 (if necessary). Plug another end to the connector
on the inverter.
5. Function switch & Controller: Plug the OSD switch mount cable to CNC1 on the controller board and another to
the OSD switch mount.
6. LED & Controller: Plug in a 3-way with dual colour LED to connector LED1 on the controller board.
7. Jumpers : Check all jumpers are set correctly. Details referring the connection diagram at
http://www.digitalview.com/controllers/csg.php
8. Jumpers & Inverter & Panel voltage: Particularly pay attention to the settings of JA3, JB2, JB3, JA5. JB2 & JB3
are used for inverter control (read inverter specification and information on the jumper table to define the correct
settings). JA3 & JA5 are used for panel voltage input (read panel specification and information on the jumper table to
define the correct settings).
9. DVI cable : Plug the DVI cable to the connector P2 on the controller board.
10. VGA cable & Controller: Plug the VGA cable to the connector P1 on the controller board.
11. Power supply & Controller: Plug the DC 12V power in to the connector PP2. You can consider to use DigitalView

General:
• If you are using supplied cables & accessories, ensure they are correct for the model of panel and controller.
• If you are making your own cables & connectors refer carefully to both the panel & inverter specifications and the section
in this manual, “Connectors, Pinouts & Jumpers” to ensure the correct pin to pin wiring.
PC SETTINGS
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 – this will not cause screen flicker.
OPERATION
Once the system has been connected and switched on there are a number of functions available to adjust the display
image as summarized in the following sections. The settings chosen will be saved for each mode independently.

CONTROLLER DIMENSIONS
The maximum thickness of the controller is 15.8mm (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 by following the steps below :
•Firstly setup the controller/display system with the buttons. With controls attached and display system active make any
settings for colour and image position as required then switch everything off.
•Use a jumper to close JP6 jumper, 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.

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 DC. This should be matched with the inverter
specification: see table.
CNB1
PIN DESCRIPTION
1 Ground
2 +12VDC
Remark: For higher power inverter, more current (for 12V) 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, 2-3 H = 5V (Vcc), OPEN H = open collector
JB3 Inverter control 1-2 H = On, 2-3 L = On

16
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 controlled 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 (OSD switch mount) pins 3 & 4: see cable design below .

17
Design Guideline for making VR circuitry :
CNB1 – Backlight inverter connector: JST B5B-XH-A (Matching type : XHP-5)
PIN SYMBOL DESCRIPTION
1 GND Ground
2 VBKL +12VDC, backlight power supply
3 BLCTRL On/Off control (enable) – see JB2 & JB3
4 BVR_WIP Brightness VR - WIP
5 BVR_A Brightness VR A
CNC1 – Control switch, JST B12B-XH-A (Matching type : XHP-12)
PIN SYMBOL DESCRIPTION
1 PSWIN Power button A
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)
6 GND Ground
7 MENU OSD menu
8 -/LEFT OSD -/Left
9 +/RIGHT OSD +/Right
10 SEL_DN OSD Select down
11 SEL_UP OSD Select up
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, ie 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.
