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.
•
••
•
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.
