CPU BUS

The CPU board, B-CPU4 is made with PC-technology components. Radisys chipset and PLD handle
all timings and signaling for ISA type CPU bus.

With B-CPU4 there is no external software cassette. Instead there is onboard flash memory where
software is loaded from the PC-card.

Powerfail or standby

When the monitor is turned to standby or the mains voltage fails, NMI-interrupt is generated by the
power control logic. The interrupt signal in the CPU means that all supply voltages except +5V for
the CPU board will be switched off shortly. NMI interrupt service program then saves all necessary
parameters in the static RAM before supply voltages fail.

When hardware detects HALT command generated from power down; all the outputs to the CPU
motherboard are left floating in high impedance state. Only DRAM refreshing cycle continues to
occur. The halt state will continue until a RESET pulse from the power control logic circuit is
received.

Watchdog functions

There are certain watchdog functions to ensure the monitor’s performance. The UPI4 board and the
primary display controller board interrupts the CPU board continuously in order to state that
everything runs smoothly. The CPU board refreshes the watchdog timer in the power supply unit in
order to prevent reset pulse. If the primary display controller board or the CPU board stops the
refreshment, the monitor will be reset in order to prevent false information to be displayed on the
screen. If the UPI4(NET) board stops the refreshment, the board will be reset internally.

CPU BUS

Control logic

IO-decoding and wait state generation takes place in GAL IC and and in the processor. Code
memory (EPROM) and working RAM (DRAM) are designed to be linear, and static RAM and EPROM
are mapped in I/O space.

Wait state generators

The processor and the GAL IC have internal wait state generators for their predecoded chip select
pins. The wait state generator in the GAL IC is used also by the other boards connected to the CPU
bus.

Halt detection

NMI-interrupt is generated by the power control logic. The interrupt signal in the CPU means that all
supply voltages except +5V for the CPU board will be switched off shortly. NMI interrupt service
program then saves all necessary parameters in the static RAM before supply voltages fail.

When hardware detects HALT command all signals generated in the CPU board as well as all the
outputs to the CPU mother board are left floating in high impedance state; only DRAM refreshment
cycle continues to occur. The halt state will continue until a RESET pulse from the power control
logic circuit is received.

External bus

External bus signals are AC logic level signals. Series resistors are used to limit signal ringing when
the signals change their states. Additional signal filtering is performed in the CPU mother board.

Main peripherals

QUART

Four series channel Quart is used.

SAA1099

IC SAA1099 is used as alarm sound generator.

Watchdog functions

The UPI board and the primary display controller board interrupts the CPU board continuously in
order to state that everything runs smoothly. The CPU board refreshes the watchdog timer in the
power supply unit in order to prevent reset pulse. If the UPI board, primary display controller board
or CPU board stops the refreshment, the monitor will be reset in order to prevent false information
to be displayed on the screen.

The software card is a flash memory card, 4MB (PCMCIA)

L-ICU01/L-ICU01A software is developed for critical care monitoring and L-ANE01/L-ANE01A is
for anesthesia monitoring. Anesthesia record keeping capability is included in the anesthesia
monitor software L-ANE01/L-ANE01A as standard. The software L-ANE01A and L-ICU01A include
extended arrhythmia analysis.

L-ANE01/L-ANE01A/L-ICU01/L-ICU01A is license software. The license agreement that is
delivered with software should be archived in a secure location. Relevant license number may have
to be referred when contacting Datex-Ohmeda service/support. The licence number is needed also
for future software upgrades.

The L-xxx01(A) software is not delivered separately without the B-CPU4 board, the software is
loaded on the B-CPU4 board already at the factory.

The L-xxx01(A)S software is used for service purpose only and is stored on a separate Software
Card (PCMCIA, 4 MB). See section 3.3.1 “Loading/replacing software on CPU Board, B-CPU4.””

CAUTION The software card is not write protected. For safety reasons do not use software

cards in any other purposes, or on any other platforms than they are designed for.
