ASSEMBLY NOTES
This controller is designed for monitor and custom display projects using 1024 x 768
resolution TFT panels with a VGA, SVGA or XGA 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 for TFT panels with 5V or 3.3V TTL or LVDS interface.
For LVDS a separate add-on board is required. Due to the variation between
manufacturers 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.
•3. LCD signal cables: 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 utilised 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 minimise signal noise.
•4. LCD connector: Different makes and models of LCD panel require different panel
signal connectors and different pin assignments.
WIRING NOTE: If panels of less than 3 x 8 bit are used, eg 3 x 6 bit, then connection of
panel signal high value should correspond to the controllers highest bit. For example for
a 6 bit panel R5 on the panel should connect to R7 on the controller, in this case R1 &
R0 on the controller will not be connected.
•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 backlights may vary it is important to match the inverter
in order to obtain optimum performance. See Application notes for more information on
connection.
•7. Inverter to Backlight Cables: (Not so relevant if the inverter is built into the LCD
panel module). These are high tension and thus prone to power leakage. Suitable cable
should be selected of minimum length, additionally care should be taken when laying out
this cable.
•8. 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).
9. 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.

•10. 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 utilised.
•Video input: With the optional video input board added it is possible to accept and
display PAL & NTSC signals with either S-video or composite signal. When the video
add-on board is fitted OSD menu functions will be available for setting video
characteristics and controlling the input source. The add-on board also provides RCA
type connectors for audio input (see next note).
•Audio control: With the optional audio add-on board it is possible to control volume
through the OSD menu. The audio board fits on the right hand edge of the main
controller.
•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 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 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.
•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.

•Touch Panels: Support for touch panels or other low power consumption accessories is
available by:
•Connector CN1 provides 5V & 12V DC which can be used to power such
accessories subject to a maximum loading recommended at 500mA.
•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 straightforward however care needs to be taken with:
•Ensuring parts have been correctly connected – both power & signal considerations.
•Checking that all jumpers & switches are set correctly.
•The input signal is compatible.
•Legal & safety requirements have been met.
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.
The steps in any order are:
•Panel signal connection.
•Panel backlight connection – Inverter & backlight tubes (see Application Notes section
for more information).
•Function controls connection.
•Accessory connection, ie indicator LED, touch panel.
Then in the following specific order:
•Input signal connection (ie from the computer, ensure the computer is switched Off)
•Power supply (DC 12V, ensure correct + & - orientation).
•Power on the PC (ensure the PC settings are suitable).
•Power on the display.
PC SETTINGS
The controller has been designed to take a very wide range of input signals however to
minimize the load on the PC’s graphics systems 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 summarised in the following sections. The
settings chosen will be saved for each mode independently.

CONTROLLER DIMENSIONS
The maximum thickness of the controller is 23mm 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 (CN6) cable.
•Use a jumper or similar to connect pins 1 & 2 on CN6, 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 CN6 the only pins that are used are for On/Off and Brightness (if controller
mounted inverter is used). On CN6 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 CN5 pin 1 is ground and pin 2 provides 12V DC. This
should be matched with the inverter specification: see table.
CN5
PIN DESCRIPTION
1Ground
2+12VDC
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.
CN5
PIN DESCRIPTION
3Enable
Further, jumpers 2 & 3 should be set to match the inverters specification for the enable pin
power and High or Low setting: see table.
Ref Purpose Note
JP2 Inverter enable voltage 1-2 H = 12V, 2-3 H = 5V (Vcc), OPEN H = open collector
JP3 Inverter control 1-2 H = On, 2-3 L = On
