INTRODUCTION

This section provides information for the maintenance and service of the Datex-Ohmeda Nellcor
Compatible Saturation Module, M-NSAT and the Datex-Ohmeda Oxygen Saturation Module, M­OSAT. The M-NSAT and M-OSAT are single width plug-in modules designed for use with the S/5
monitors. The M-NSAT module utilizes Nellcor’s pulse oximetry algorithm and it should be used
with Nellcor’s pulse oximetry transducers only. The M-OSAT module utilizes Datex-Ohmeda pulse
oximetry algorithm and it should be used with Datex-Ohmeda OxyLead Compatible and Integrated
sensors. Only one pulse oximetry source at a time is allowed by the monitors. If M-NE(12)STPR/M­NE(12)STR/M-ESTPR/M-ESTR and M-NSAT or M-OSAT modules are plugged in the monitor
simultaneously, then M-NSAT or M-OSAT overrides modules mentioned above as a pulse oximetry
source.

2 FUNCTIONAL DESCRIPTION

2.1 Main components of M-NSAT

The M-NSAT module consists of the following parts

Oxygen Saturation Modules, M-NSAT, M-OSAT

• SpO

sensor board

2

• Sensor connector cable

• Nellcor Pulse Oximeter Module MP-204

• NSAT interface board (NIO)

Sensors can be plugged into the M-NSAT module either directly or using sensor extension cables
available from Nellcor. Sensors are plugged into a 9-pin female connector (D-type) on the front
panel of the module. This connector is mounted on a small PC board, which is connected by a flat
cable to the MP-204.

The MP-204 is a surface mounted PC board manufactured by Nellcor Incorporated. It contains the
signal processing electronics and software that are based on Nellcor’s stand-alone pulse
oximeters. The MP-204 is used with an internal preamplifier.

The measured SpO

and pulse rate values, as well as status information, are transferred from the

2

MP-204 to the NSAT interface board. Communication between the MP-204 and NSAT interface
board is established through RS232C serial interface. The NSAT interface board, in turn, transmits
the measurement information to the module bus of the monitor through RS485 serial interface.

2.2 Main components of M-OSAT

The M-OSAT module consists of the following parts

• SpO

• Datex-Ohmeda Proloque module board

• OIO interface board

Sensor can be plugged into the M-OSAT module either directly or using sensor extension cables
available from Datex-Ohmeda. Sensors are plugged into a 9-pin female connector (Datex­Ohmeda) on the front panel of the module. This connector is mounted on a small PC board, which
is connected to the Proloque module by a cable. The EMC ferrite of this cable is mounted at the
back of the front panel.

sensor board and cable set

2

The Proloque module board is a surface mounted PC board manufactured by Datex-Ohmeda. It
contains the signal processing electronics and software. The Proloque module is used with an
internal preamplifier.

The measured SpO

and pulse rate values, as well as status information, are transferred from the

2

Proloque module to the OIO interface board. Communication between the Proloque module and
OIO interface board is established through RS232C serial interface. The OIO interface board, in
turn, transmits the measurement information to the module bus of the monitor through RS485
serial interface.

RS485 drivers

There are drivers for data and for module reset functions.

These drivers are used for driving the RS485 type serial communication bus between the module
and the Central Unit. Data transmission speed of the bus is 500 kbps.

In addition to RS485 bus RESET, there is a Power-up reset, which keeps the RESET pin of the CPU
active during power up for about 500 ms despite of the state at the RS485 bus RESET. This is used
to prevent the sending of RS485 data during the RESET of the module.

Power supply, non-isolated section

Power supply is a half bridge type switched mode circuit, where the driver FETs are controlled by a
quartz oscillator. The load of the half bridge is the primary of the isolation transformer. The voltage,
+15 Vdirty from the Central Unit is used as the supply voltage of the switched mode circuit.

Document No. 8002219

Power supply, isolated section

The secondary voltages of the isolation transformer are rectified, filtered and regulated. The
voltages can be measured from the test connector X11. See Chapter 2.3.2 Other connectors.

Opto isolation

The signals of the serial communication bus between the NIO or OIO Interface board and the
Central Unit are transferred through the patient isolation by the high speed opto couplers.

Microprocessor, UART, non-volatile memory

The microprocessor with on-chip memory has been used to convert and transfer data from Nellcor
pulse oximeter module MP-204 or Proloque module to the monitor.

The communication between MP-204 or Proloque module and the CPU of NIO or OIO Interface
board is realized with the bidirectional asynchronous serial communication via the UART.

The non-volatile memory has been used to store identification information like serial number,
control number, date etc.

3 SERVICE PROCEDURES

3.1 General service information

Field service of the M-NSAT or M-OSAT module is limited to replacing faulty circuit boards or
mechanical parts. The circuit boards should be returned to Datex-Ohmeda for repair.

Datex-Ohmeda is always available for service advice. Please provide the unit serial number, full
type designation, and a detailed fault description.

CAUTION Only trained personnel with appropriate equipment should perform the tests and

repairs outlined in this section. Unauthorized service may void warranty of the unit.

Document No. 8002219

Datex-Ohmeda S/5 monitors

3.2 Service check

These instructions include complete procedures for a service check. The service check is
recommended to be performed after any service repair. However, the service check procedures can
also be used for determining possible failures.

The procedures should be performed in ascending order.

The instructions include a check form (Appendix A) which should be filled in when performing the
procedures.

The mark

? in the instructions means that the check form should be signed after performing

the procedure.

The procedures are designed for monitors with software of level 00. However, most of the
procedures also apply to monitors with older monitor software.

NOTE: Preamp Error is indicated on the service menu, even though module contains MP-204
board.

NOTE: The status and error indicators are not valid for the M-OSAT.

PR shows the pulse rate value [bpm] calculated from pleth.

SpO

% shows the oxygen saturation value multiplied by 100.

Next are listed the messages that are sent from the module to the monitor. Digit ‘0’ means that the
message is not active, ‘1’ is for the active one.

Preamp Error indicates ‘Yes’ if the Preamp (MP-203(4)) board detects an error.

QUART Error indicates ‘Yes’ if an error is detected in the operation of QUART that is located in the

Interface board.

I/O Error indicates ‘Yes’ if an error occurs in the communication between Preamp (MP-203(4)) and
Interface board.

Timeouts is a cumulative number that indicates how many times the module has not responded to
the monitor’s inquiry. Bad checksums is a cumulative number that indicates how many times
communication from the module to monitor broke down.
Bad c-s by mod is a cumulative number that indicates how many communication errors the
module has detected.
The monitor starts counting these items at power up and resets to zero at power off. The nonzero
values do not indicate a failure, but the continuous counting (more than 50 per second) indicates
either serial communication failure, or module not in place. Also other modules can cause
communication errors that cause these numbers rise.

16

Document No. 8002219

ROM indicates whether the checksum in the EPROM is in accordance with the one the software has
calculated.
The state is either OK, Fail or ? (module not in place or a communication error).
