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
1
2
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
3
Further, jumpers 2 & 3 should be set to match the inverters specification for the enable pin
power and High or Low setting: see table.
