2.1 Electrical system

2-2
The electrical system consists of two main computing units: the Display Unit and the
Anesthesia Control board. Additional subsystems interact with these computing hosts
to perform various gas delivery, ventilation, and monitoring functions.
The Display Unit handles the main user interface functions and connections to external
devices. The Display Unit software runs on the Windows CE operating system.
Therapy functions are handled by the Anesthesia Control board. The Anesthesia
Control board is based on the Motorola Coldfire processor with a Nucleus operating
system.
Embedded controllers are used to perform specific machine functions on subsystems
like the Power Controller board and the Mixer board.
The processors communicate through serial bus channels.
The various functions of the electrical system are accomplished on the following:
• Display Unit (HPDU) CPU (A)
• Display Unit System Interconnect assembly (B)
• Display Connector board (C)
• Power Controller board (D)
• Anesthesia Control board (E)
• Pan Connector board (F)
• Electronic Mixer board (G)
• Electronic Vaporizer (H)
• Ventilator Interface board (I)
• ABS Filter board (J)
• Vent Engine Connector board (K)
• MGAS Power Supply board (L)
• Light Strip board (M)
• Auxiliary Connector board (N)
• Inrush board (O)
• Toroid (P)
