ASSEMBLY NOTES This controller is designed for monitor and custom display projects using 1280 x 1024 or 1024 x 768 resolution TFT panels with a VGA, SVGA, XGA or 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. LCD Panel This controller is for TFT panels with 3.3V, 5V or 12V TTL or LVDS/TMDS interface. For LVDS/TMDS 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 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. LCD connector board 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 Red data bit on the panel should connect to R7 on the controller, in this case R1 & R0 on the controller will not be connected. Same for Green & Blue. LCD signal cables 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 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. 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 for more information on connection. 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. 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. Function controls cable The cables to the function switches should be of suitable quality and length so that impedance does not affect performance.

Audio add-on board 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. 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. • AV cables Standard Composite or S-video cables can be used. Reasonable quality cable should be used to avoid image quality degradation. • Power Input 12V DC 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.
