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 run 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 function of the electrical system are accomplished on the
following circuit boards:
• Display Unit 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)
• Ventilator Interface board (H)
• ABS Filter board (I)
• Vent Engine Connector board (J)
• MGAS Power Supply board (K)
• Light Strip board (L)
• Inrush board (M)
