CPU BUS

The CPU board, B-CPU5/B-CPU4 is made with PC-technology components. Radisys chipset and
PLD handle all timings and signaling for ISA type CPU bus.

The B-CPU5/B-CPU4 contains an onboard flash memory where software is downloaded from a
software 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.

Document No. 8002948

Watchdog functions

There are certain watchdog functions to ensure the monitor’s performance. The UPI4(NET) board
and the primary display controller board interrupt the CPU board continuously in order to state that
they function properly. 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.

SRAM M48T18

Lithium battery back-up 8 kB static RAM with a real-time clock.

CAUTION The IC contains a lithium battery. Discard the battery according

2.2 Software Cards, U-xxxxxx/L-xxxxxxS/S-xxxxxS

Upgrade software, U-xxxxxx and Service software, L-xxxxxxS/S-xxxxxS are delivered on an 8 MB/4
MB PCMCIA flash memory card.

The upgrade software has been developed for monitor software upgrades. The uprgade software
can be downloaded onto a monitor that is equipped with the B-CPU5/B-CPU4.
The service software has been developed to replace the original monitor software in case of a B­CPU5/B-CPU4 failure. The service software is downloaded onto a replacement empty B-CPU5/B­CPU4. See section 3.3.1 “Downloading/replacing software on CPU Board, B-CPU.””

There is service software available of each S/5 monitor software version. The functionality of the
service software is equal to the functionality of the corresponding original S/5 monitor software.

The Service software, L-xxxxxxS is license software. The license agreement that is delivered with the
software should be archived in a secure location. Relevant license number may have to be referred
when contacting Datex-Ohmeda for service/support. The licence number is needed also for
possible software upgrades.

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.

line between CPU board and UPI board or with the boards
themselves.

The 10 ms tick shows how many 10 ms intervals the UPI
microprocessor has been on after last UPI reset. The UPI
microprocessor counts the 10 ms intervals. The number
must be running all the time at the frequency of 100 Hz. If
the number doesn't rise, the problem is in the UPI board.

Serial I/O (RS-232) view shows information about the
communication through the UPI board RS232 serial
connector X3.

Interface status shows whether the interface through the
connector is OPENED, ACTIVE or CLOSED. Opened
indicates that the hardware and software for the interface
is running but there is no connection or that there have
been errors in using the interface. Active indicates that
the interface is operating normally. Closed indicates that
the necessary hardware is not present.

Statistics In/Out show the numbers of received and
transmitted data packets and data bytes.

Rx errors show the number of received erroneous data
packets.

S/5 Anesthesia Monitor and S/5 Critical Care Monitor

5.6 Set/Test

The power supply unit contains a watchdog circuitry,
which needs refreshment at every 1.5 seconds. If the
refreshment did not occur, the watchdog circuitry will
reset the main CPU. In normal operation the main CPU
refreshes the watchdog circuitry at every 0.2 seconds.

The purpose of the watchdog circuitry is to restart the
monitor if there was a serious malfunction. This feature is
useful in two cases: when the main CPU is not able to
control the monitor, or when the CPU controls the monitor
but detects a serious malfunction. Watchdog tests check
proper functionality of the watchdog circuitry in various
conditions.

Watchdog test ensures directly that the watchdog of the
power unit functions properly. Choosing this test prevents
the watchdog circuitry from refreshing and shows running
seconds with an accuracy of 0.1 seconds.

The test should have the following result when the
watchdog circuitry is working properly: The monitor will
restart after 1.5 seconds from the start of the test. In
malfunction: ‘>20 s’ is displayed, and the test will
interrupt. In this case, the fault is in the watchdog circuitry
of the power unit.

WD by Overload test ensures the functionality of a
feature, where the software controls the monitor, but
detects an overload situation in the main CPU.

The test should have the following result when the feature
is working properly: The monitor will restart after 15
seconds from the start of the test.

WD by UPI test ensures the functionality of a feature,
where the software controls the monitor, but detects a
malfunction in the UPI processor and restarts the
UPI4(NET) board. The test will prevent the UPI processor
from functioning during the test.

The test should have the following result when the feature
is working properly: The monitor will restart the UPI4(NET)
board without any visual effects.

WD by GSP ensures the functionality of a feature, where
the software controls the monitor, but detects a
malfunction in GSP processor (located on the primary
display controller board) and performs a restart. The test
will prevent GSP processor from functioning during the
test.

Immediately after the test starts, the screen update
stops. The test should have the following result when the
feature is working properly: The monitor will restart after 5
seconds from the start of the test.

Factory Reset restore factory default settings and clear
data memories. Factory reset should be run if monitor
software is replaced or if the SRAM/Timekeeper battery is
replaced.

5.7 Service Log

Error, event, alarm and maintenance data is stored in
Service Log.
The service log contains information about the occurred
monitor errors, events and alarms since the last factory
reset or service log reset. The service log is saved in the
EEPROM memory of the main CPU board. The user can
also store different maintenance events to the
maintenance log.

Maintenance menu is for setting and viewing the
maintenance information of the monitor

Error History is for selecting the error history view onto the right side of the menu. Event History is for selecting the event history view onto the right side of the menu. Alarm History is for selecting the alarm history view onto the right side of the menu. Scroll Last Er (Ev) is for scrolling the error / event / alarm information on the right side of the menu. Scroll Counters is for scrolling the error / event / alarm counters on the right side of the menu. Record Data is for recording the service log information onto the M-REC paper, the laser printer or the memory module depending on the selection in the Record Data service menu. Reset Log is for clearing up the content of the service log. This function is recommended to be run after a performed maintenance. In Error/Event history view the Reset Log command clears up both error and event log. In Alarm History view the Reset Log command resets only the alarm history log.

5.7.1 Error History

Last errors: The section shows the last monitor errors

and the time of their occurrence.

Error counters: The section contains counters for each
different (detected) monitor errors. The time of
occurrence of the last error is shown beside each counter.
Last log reset: The date and the time of last Error/Event
log reset.

Possible errors:
Fast cold start indicates a number of erroneous cold
starts with power off time less than 20 seconds. The
reason can be either a failing lead acid battery or a
software problem that was solved by the hardware
watchdog circuitry located in the monitor’s power supply
unit.
GSP watch-dog time-out indicates an erroneous restart
controlled by the main CPU board and caused by the
display controller board. The restart is listed as a fast cold
start.
UPI watch-dog time-out indicates an erroneous restart
controlled by the main CPU board and caused by the UPI
or UPINET board. The restart is listed as a fast cold start.
