2.3 Display Unit
The Aisys anesthesia machine uses the High Performance Display Unit (HPDU).
The Display Unit handles most of the machine’s user interface functions through the
front panel controls and the LCD screen. It is the primary interface to external
peripherals.
The main components of the Display Unit include:
• An active matrix thin film transistor liquid crystal display (A)
• The CPU board (B)
• The System Interconnect assembly (C)
The CPU board includes a host processor and three coprocessors to handle display,
front panel, and monitoring interfaces.
The Display Unit includes a Compact Flash interface (D) to handle software upgrades
and to load the Special Functions diagnostics.
The HPDU uses a lithium battery to power the real time clock when the machine is in
Standby or Off states. The HPDU also uses the lithium battery to retain the BIOS setup.
If the battery is removed or becomes disconnected, the BIOS setup needs to be
restored by booting the system off the Software Download Card.
