The Power Controller board provides outputs to the Anesthesia Control board and the
Display Connector board. These boards provide distribution of power supplies required
by the system.
The Anesthesia Control board interfaces with the Mixer board, the Ventilator Interface
board, and the Agent Delivery board through the Pan Connector board.
The Display Connector board interfaces with the Display Unit and the Module
assembly.
