The following provides some guidelines for installation and preparation of a finished display solution.
20. Interface for connecting to HD-SDI adaptor board HD-SDI (1-in-1-out) adaptor board, Kit number P/N 546013410-3 includes : HD-1000 adaptor (1-in-1-out) P/N 416013410-3 Ribbon cable P/N 426171120-3, 180mm HD-SDI (2-in-2-out) adaptor board, Kit number P/N 546013310-3 includes : HD-2000 adaptor (2-in-2-out) P/N 416013310-3 Ribbon cable P/N 426171120-3, 180mm 21. Power Input: 12V/24VDC is required, this should be a regulated supply. The power rating is depending on the panel and inverter used.
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.

CONTROLLER DIMENSIONS The maximum thickness of the controller is 20.6mm 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.
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.
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.
TROUBLESHOOTING General A general guide to troubleshooting a flat panel display system it is worth considering the system as separate elements, such as: ¾ Controller (jumpers, PC settings) ¾ Panel (controller, cabling, connection, panel, PC settings) ¾ Backlight (inverter, cabling, backlight tubes) ¾ Cabling ¾ 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

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.
