Brightness: There are various methods for brightness control and it is important to consider
the specifications for the inverter to be used. Generally the situation is:
•
Brightness can controlled by using a resistor or VR (Variable Resistor).
•
Brightness controlled by adding a circuit such as PWM (Pulse Width Modulation).
•
No adjustment of brightness is possible.
CN5 pins 4 & 5 are available for connecting to an inverter or circuit where VR control is
supported.
