Understanding The Binary Chart

Explaining Binary Code
Binary codes are a series of LEDs that are lit and read from right to left. Each column has a number above
it and will double its value going from right to left as shown here. Lit LEDs will correspond with the number
in the far left column of the chart below. This is done by adding the numbers at the top of the column of the
cycle status LEDs that are lit.
Example
Add the numbers of the lit LEDs together.
1 + 2 + 4 + 8 = 15
So it is in test 15
