Test Mode
Test Mode allows you to, well, test the board.
Let's break these down
Alternate Channels​
Slow Sine Wave​
All channels start at zero. They all go to 255, and all back to zero. If you graphed the value of any given channel over time, it would be a sine wave.
It does this slowly.
Fast Sine Wave​
All channels start at zero. They all go to 255, and all back to zero. If you graphed the value of any given channel over time, it would be a sine wave.
It does this faster.
Sine Ripple​
Plot channel numbers on x axis against values on y and you'll get a sine wave. That sine wave moves over time, so each channel moves between 0 and 255 and back.
It does this medium speed.
DMX Preset​
Allows you to select a DMX preset that you've created as a test mode
