The control board is primarily a digital device, and as such does not require any negative DC voltages. The primary supply voltage is +5V, thus greatly simplifying both the power supply and power distribution methodology. Figure 27 shows the pinouts for the connector used to distribute power to each of the PC boards inside of the control board.

There shall be 10$\mu$F of power supply bypass capacitance for each supply line used on each PC board. Additional 0.1$\mu$F bypass capacitors shall be placed near each IC, as appropriate.
