How a Rev3 Selador Control Card Auto Calibrates

The Selador Switched Linear card, 7400B5615, sends a sense current to the fixture's LEDs.  This signal is then converted to voltage and amplified then sent back to the fixture's processor.  The processor measures the current to see if it is in the acceptable range predetermined for each color string.  If not, it steps up the sense current and sends again until it is within the acceptable range.
