Figure 3: Example of PRBA coding used in the instrument design. Two colors are used to represent the bits of the PRBA. The '0' and '1' are added for clarity. The color black is used to separate two data bits. The PRBA coded is this case is


	0 1 1 1 1
	0 0 1 1 0
	0 1 0 0 1

Note that the corner points of the squares used make up a grid.
