Chapter 1: General Information

1Introduction

This Manual is intended to serve as a source of technical information for

qualified personnel to use in servicing SC 7000 and SC 9000XL Monitors

and associated peripheral devices. In light of the state-of-the-art technology

used in the manufacture of Siemens' equipment, proprietary nature of the

software, and specialized equipment required for replacement of most

individual parts, Siemens policy (see Section 3) is for SC 7000 and SC

9000XL monitors, and peripheral modules specifically related to the SC

7000 or SC 9000XL, to be serviced only to the field-replaceable

subassembly level. Replacement of components other than those listed in

“Appendix A: Replacement Parts”, should be performed only at Siemens

service depots.

2 Overview

SC 7000 and SC 9000XL patient monitors have been designed to function

as a portable or a stationary monitor with equal ease. Each has an internal

main battery, as well as provision f or an additional exte rn al (aux iliary )

battery for extended operation as a portable monitor. For stationary

operation near a bedside, the monitor is placed on a specially designed

docking station attached to a shelf, wall, or IV pole that securely locks it into

place. While on the docking station, the monitor is powered by an external

power supply that also charges the monitor's main battery and external

battery (if installed). In addition, the docking station provides audio, video

and data signal connection to the local network as well as a variety of locally

installed peripheral devices such as a remote display/controller, recorder,

MIB converter, and Surgical Display Controller or SDC (sometimes referred

to as the Independent Surgeon Display or ISD). NBP is included as an

integral function. For airway and sidestream CO

2

monitoring, an etCO

2

cartridge can be installed on a slide mount on the back of the SC 7000.

Employing the "pick-and-go" concept, the monitor is simply picked up off of

the docking station to return it to portable operation, with no interruption in

patient monitoring.

2.1 R50 Recorder

An R50 Recorder connects to the SC 7000 and SC 9000XL via a CPS or

IDS. The recorder may be either a network or local recorder, depending on

configuration of a CPS. If plugged directly into an IDS, the recorder

functions as only a local recorder for any monitor mounted on the IDS. For

standalone portable operation, an interface plate can be used to provide

recorder connection. The R50 Recorder prints on 50mm wide paper, and

has three control keys -- Start Cont., Alternate Speed, and Stop.

2.2 I

NFINITY

Docking

Station

The I

NFINITY

Docking Station (IDS) is an active device. With its separate

power supply it replaces the discontinued Basic I

NFINITY

N

ET

CPS and

Docking Station combination (see Sections 2.3 and 2.4). As a docking

station, it serves as a secure mount for SC 7000 and SC 9000XL (and also

for SC 9000, SC 6000P and SC 6002) Monitors in “Pick-and-Go”

operations. When equipped with a MIB Option, an IDS provides the

combined functionality of a Device CPS and Breakout Box.

2.3 Docking Station

(Discontinued)

A docking station is a passive device that provides a sturdy mount for the

SC 7000 or SC 9000XL while supporting the "pick and go" concept. The

docking station mounts near a bedside, attached to a shelf, wall, or an IV

pole, and provides pass-through to a CPS for the signals from a SC 7000

or SC 9000XL. A second docking station supports peripheral devices such

as the R50 Recorder.

Chapter 2: Theory of Operation

1Introduction

The SC 7000 and SC 9000XL are high-end single-board patient monitors.

The board provides the following parameters; 6 lead ECG, Respiration, two

Temperatures, SpO

2

, NBP, four IBPs, Cardiac Output, an interface

connector for an etCO

2

cartridge, and two onboard 5 watt patient isolated

ports for additional parameters. It has connectors for flat panel display,

simultaneous CRT, user interface, audio, batteries, NBP pneumatic

assembly, chart recorder, analog out, defib sync, memory card, Uarts, and

"Pick & Go" docking connector. The board contains the computer, power

supply and patient isolated front ends.

Computer Archictecture Hardware architecture of the monitors is based on a dual processor design

using two Motorola MPC860s with onboard cache. The main processor is

responsible for graphics and communications, while the second processor

is dedicated to data acquisition and algorithm processing. A DSP

subsystem preprocesses the front end data.

There are three major bus structures within the system; MAIN processor

bus, FRONT END bus, and REMOTE COMM bus (see Figure 2-1). The

buses operate at different speeds and efficiency. The FRONT END bus and

REMOTE COMM bus have multiple bus masters and common memory to

allow exchange between I/O devices.

The REMOTE COMM bus is special in that it may be connected and

disconnected without causing a monitor fault. This patented connect and

disconnect function of the monitor is advertised as "Pick and Go". This

allows monitors to be moved to different locations within the hospital and to

connect to multiple REMOTE COMM links without interruption of

monitoring. The traditional central station alarm function of alarming when

the patient monitor is suddenly disconnected from the network is modified

in this system by ensuring that a disconnect is intentional. A redundant

signal is used to verify a true “pick-and-go” such that a single fault does not

prevent an alarm by imitating a “pick-and-go.”

1.1 Main Processo r Bus

The Main processor bus is a 32 bit data bus connecting the MPC860 to its

main bank of 16 meg DRAM memory. The Program for the monitor is stored

in 8 meg Flash memory and uploaded to DRAM during initialization. The

DRAM is optimized for multiple word transfers allowing efficient cache fills.

This bus has an optional daughter card connector allowing expansion of the

main memory space. The graphics controller is connected to this bus to

allow high bandwidth access to video memory. The bus has a max

bandwidth of 40 megbytes/sec.

This bus also has an I/O space implemented in an FPGA. These functions

include audio, chart recorder interface, keypad and rotary knob interface,

and EEPROM. The EEPROM con tains serial #’s, calib ration const ants and

configurations. The I/O space also includes the Bridge to the FRONT END

bus and a port to the REMOTE COMM bus. The Bridge to the FRONT END

bus is unidirectional. This means that the Main processor may read and

write to the FRONT END bus, but the Front end processor can not access

the MAIN bus.

1.2 Front End Bus

The Front End bus is a 32 bit data bus connecting the second MPC860 to

its main bank of 4 meg DRAM memory. The program for this processor is

downloaded from the main processor during initialization. The DRAM is

optimized for multiple word transfers allowing efficient cache fills. Both

processors contain 512K of battery-backed SRAM for trend and other

patient data storage. Data is exchanged through the common memory.

This bus has multiple bus masters that include the following:

• Front End 860

• Main 860

• DSP DMA

• POD Comm DMA (a POD is a configured front end)

• DRAM Refresh

Figure 2-2 REMOTE COMM Bus

1.3 REMOTE COMM Bus

The R EMOTE COMM b us ( Figure 2-2) is a bus extender used to extend the

main bus to a second chassis. The parallel address bus and data bus are

serialized using high speed FDDI transceivers, allowing virtual parallel

access to a remote parallel bus. The parallel bus is located in the CPS

communication power supply module or in the Iinfinity Docking Station

(IDS). This bus interfaces to a network controller and other local serial

buses including MIB, lGraphics, Gas Monitoring, and other peripherals. The

host is stalled until completion of all read operations, but is released after a

write is latched to be serialized.

1.4 Error Handling

The hardware provides several cir cuits for error detection, error recovery,

and safety. The main proce ssor bus, f ront end pr ocessor bus, and REMOTE

COMM bus both have timeouts implemented w ith the arb iter to pre vent a lock

up of the sy st em . T he RE M O T E C OMM bus al so contain s a C RC for serial

transmis sion to and from t he CPS or IDS. I f a b ad CRC is detected an

interrupt is sent to the mai n 860. The main 860 and the Front End 860 are

both protec ted with watchdog t imers. I f a timer expi res, the system i nitiate s a

reset and restarts the monitor.

The power supply is also monitored with a piezo alarm that sounds during

power up (for test) and power down. This is to alert the user that the monitor

has turned off. The piezo alarm does not sound during a "Pick and Go"

since the monitor switched to battery operation without interruption. The

piezo is also sounded continuously if the monitor does not reset properly

after a watchdog timer has expired and the computer has halted.

Figure 2-3 SC 7000 / SC 9000XL Block Diagram

2Main Unit

Both monitors are designed to be lightweight and portable. The division of

the REMOTE COMM bus and internal buses are a direct mapping of what

is needed during transport and what can be left in the patient’s room. The

REMOTE COMM bus is connected and disconnected via a docking station

which has a locating feature for the monitor as well as a locking latch. The

main unit has been designed as a single board computer. In addition to the

main board there is a front bezel board to interface to a flat panel display,

and a connector board used as a cable harness in the rear chassis. The

main processor board contains three sections (see Figure 2-3): processor,

power conversion, and front end. Each section is shielded from the others.

Processor Section The processor section co nt ai ns all compute r f unctions of t he m onitor. It

contains t wo M P C 860 processors, a VGA graph ics controll er, and a 2181

DSP. All of t hese devices co mmunicate using one large FPGA (field

programmable gate array) that is downloaded at init ial ization. The F P GA

contains all custom circuitry used in t he computer, including the processor

bridge, remote comm transmitter, pod com DMA, DSP interface, NBP

interfac e, and I/O interface s for both processors. Configur at i on of the FP GA

may be updat ed with the Software throu gh t he m em ory card adapter.

Power Conversion Section The power conversion section operates on a DC input from +11 to +15

volts. It switches between the external supply, the external battery and the

internal battery for the proper power source, and generates all necessary

dc voltages for the unit. It charges and maintains the internal and external

battery. This section also contains the patient isolation for the two internal

front ends as well as two general pod comm ports. It also has the power

control for the NBP pneumatics.

Front End Section The front en d cont ain s Multi Med and HemoM ed circ uit ry. T he M utiM ed fro nt

end provid es the following parameters ; 6-lead ECG, Respi ration, Puls e

Oximetry , and Temp erature . The NBP pressur e transd ucer is al so con tained

in this front end. The fr ont end is based on a si ngle 16 bit over sampling

converte r. Oversampling allows for a reduction i n anti-aliasing anal og

circuit ry while maintaini ng superior noise r ej ec tion. The HemoMed front end

provides four invasi ve pressures and Thermal Dilution Cardiac Output.

2.1 Front Bezel Board

The front bezel board is an interface board used to adapt a particular LCD

panel to the processor board. It also interfaces the front bezel rotary knob

and keypad to the processor. The front bezel board contains the backlight

invertor with a PWM input to allow for LCD brightness control in order to

save power.

2.2 Cooling System

The cooling system for the main monitor is convection based and uses a

patented chimney approach. The chimney is comprised of a heatsink which

cools the electronics and a plate which cools the LCD backlight. The

chimney is in the middle of the monitor and therefore is vented on top and

bottom. These vents should remain unobstructed for proper operation. The

chimney is waterproof and accidental liquid entering the chimney is safe.

CARE should be taken to operate the monitor below 45° C and store the

monitor below 60° C, since damage to the LCD can occur at 70° C. If the

internal temperature of the circuit board exceeds 80° C the monitor shuts

down to prevent damage to the electronics. The monitor does not restart

until the temperature is below the shut off value.

2.3 Real Time Clock

The Real Time Clo ck fu n ction is implemented with the EPSON- SEIKO

RTC4513 device, and is synchronized by the Central Station.

2.4 Non-volatile Memory

Battery Backup and

Power Reset

The shared RAM and real time clock are provided with a lithium battery

backup circuit to prevent corruption of this non-volatile memory during a

power loss condition (both primary and battery power are lost). Note that

the battery used for non-volatile memory backup should not be confused

with the internal and external batteries that are used to provide power to the

monitor base unit when primary power is lost. Non-volatile memory lithium

battery backup is controlled by a power supervisory device that provides a

power reset during a power loss condition.

Note: No provisions have been made to recharge this non-volatile

memory backup battery. Eventually (≈10 years), the battery must be

replaced.

SCC4 MVP-2 UART selectable baud

SMC1 main diag UART 19.2 Kbaud

SPI a/d (power monitor)

Front End Processor SCC3 serial pod data

SCC4 serial pod data

SMC1 front end diag UART

An additional UART implemented in the FPGA contains a large FIFO and

interfaces to the chart recorder.

2.6 Device CPS

A CPS (communication, power supply) has three boards -- power supply,

network board, and connector board, and allows for connection to an

INFINITY network as well as MIB and CAN. The FPGA and main program

memory are downloadable by the SC 7000 and SC 9000XL. The power

supply is a medical grade universal supply operating from 88 to 264 vac.

The Docking Station is a passive device that serves as a sturdy mount for

SC 7000 and SC 9000XL (as well as SC 9000 and SC 6000 series patient

monitors), in support of the P

The Infinity Docking Station base unit (IDS) with its separate power supply,

replaces the CPS and Docking Station combination in an I

NFINITY

N

ETWORK

. As a docking station, it serves as a secure mount for the patient

monitors, as above, and also provides the network and peripheral device

connectivity of a Basic CPS. When equipped with a MIB 1-2 Option, it

provides the functionality of a Device CPS and Breakout Box.

2.8 etCO

cartridge

The etCO

2

cartridge is a hardware component attached to the back of the

SC7000 or SC 9000XL. The cartridge is a self contained computer capable

of mainstream and side stream measurements.

2.9 External Battery

The external battery is a low cost lead acid battery and may be charged in

either the monitor or with an external charger. The external battery may be

hot-swapped to extend battery life during transport.

2.10Interfaces

2.10.1 Local Fixed Keys Interface There are twelve fixed function keys on the monitor base unit, and a fixed

key dedicated as a power on/off switch. The power on/off switch is unique

in that it is not directly available via a status read command. The on/off

switch is input to the power supply subsystem interface, where the switch

state is detected and processed. Detection of a power off condition causes

an interrupt to the host processor.

2.10.2 Local Rotary Knob Interface The rotary knob is a 16 detent rotary knob. Each detent position indicates

a "click" clockwise or counter-clockwise. The change in detent position is

detected via a 2 bit quadrature code that changes value every time the

rotary knob is moved into a detent position. Also included in the rotary knob

is a push button switch that is operated by a press/release action. This

switch is used to select menu items on the screen.

7k9kXLTM.c2. CD_R OM .fm/0 4-99/ k aupp

2.10.3 SC 9015 Interface The SC 9015 Interface is implemented in the main processor

communication channels. SCC2 has been dedicated as the channel

between the remote monitor and the base unit, and provides a full duplex

transmit/receive channel from/to the remote monitor. This interface enables

the fixed keys and rotary knob on the remote display to control the main

unit, in parallel with controls on the main unit.

2.10.4 Fast Analog Output The ANALOG OUT interface consists of two identical channels. Each

ANALOG OUT channel provides a 12 bit D/A function. The design uses a

dual DAC to produce the D/A conversion. The sampled analog data is then

passed through a 2 pole low pass filter. The analog output has a maximum

delay of 20ms, and can be used for a defibrillator or balloon pump.

Separate Pacer Spike generation circuits for analog outputs 1 and 2 are

provided.

2.10.5 HiFi Audible Alarm Interface The Audible alarm interface consists of an FM synthesis and Audio DAC

chip set. There is also power amplifier drive circuitry for the two speaker

interfaces: the internal speaker located in the base unit and the speaker

located in the remote CRT. Circuitry has been included to provide a

mechanism for automatically generating an error tone when a watchdog

failure occurs via the piezo alarm (see Section 6.1.8)).

The chip is loaded with tone frequency, pitch, harmonics, and volume

information by the host processor, which controls the duration of the tone.

The audio DAC converts the received sampled tone data and produces a

sampled analog representation of the tone data.

The local speaker interface (also designated as main speaker interface) is

designed for an 8 ohm speaker load. This local speaker interface produces

1 watt of power into an 8 ohm load, and has thermal shutdown capability.

The remote speaker interface is designed to produce a 1Vrms maximum

signal into a 1 kohm load, and provides an ac coupled output.

2.10.6 LED/Status Interface Fi ve LEDs provide information in the present SC 7000 and SC 9000XL

configurations. Two are dedicated to the front end processor, to the DSP,

and two to the main processor.

2.10.7 QRS Sync Out Interface A QRS sync output is provided. The QRS SYNC OUTPUT is an open

collector type output driver that is pulled up to +12 volts (active HIGH). The

output is initialized to Gnd on reset or power on.

This QRS signal is available via an external connector mounted on the main

PC board. High level = +6V min (10KΩ load), +12.6V (no load); Low level

(no QRS) = 1V @ 5ma.

2.10.8 Local Alarm Out Interface A Local Alarm output is provided. This Local Alarm Output is an open

collector type output driver that is pulled up to +12 volts. The output is

initialized to ground (0 volts) on reset or power on (active HIGH).

Loopback status is available via a status read command.

The Local Alarm Out signal is available via an external connector mounted

on the main PC board.

2.10.9 Remote Alarm Out Interface

for Nurse Call

The Remote Alarm Output Interface is located in the CPS/IDS subsystem.

This output is an open collector output with a +12V pullup resistor, fed from

the monitor. The Remote Alarm Output is silenced when a monitor is

undocked.

2.11Recorder Interface

The Recorder interface has been designed to connect to an external

recorder via the base unit docking station connector. The recorder interface

provides all of the necessary control, data and power supply signals

required to drive an external recorder. The interface consists of current

limited DC power and a UART with handshake signals. The UART is

implemented in the main processor FPGA to allow for an extended FIFO.

2.12Backlig ht Cont rol

SC 7000 and SC 9000XL displays require a fluorescent backlight for visibility.

The backli ght in vertor is located o n the fr ont beze l board . Intens ity of th e lig ht

is control led by a variable power ac i nverter and i s bas ed on ambient l ight

detection as well a s operator se l ection. A 10 KH z 6 bi t PWM is implemented

in the main processor FPGA, and a filter on the front bezel b oard converts

this digital signal to an analog volt age to control t he backlight i ntensity.

2.13Serial EEPROMS

Four serial EEPROM devices, which contain the Monitor serial number,

Ethernet address, NBP pneumatic characterization and calibration

constants, and monitor setups, are located on the connector I/O board and

are part of the rear housing. If the main processor board is replaced the

monitor will keep its set ups from the se serial EE PR OM s.

Two EEPROMs can be written only at the factory, and contain the Monitor

serial number and Ethernet ID address. The other devices are writable by

the main processor and are changed during service menu setups. These

devices are used for the monitor as well as network setups, device

compatibility, and software feature locks.

Figure 2-4 Graphics Subsystem

3Graphics Subsystem

3.1 Overview

The Graphics Subsystem is based on a commercial VGA controller (see

Figure 2-4), and drives both a CRT and LCD display from a local memory

used to refresh the screen. It uses a special video crystal which enables it

to synchronize to most video standards. The graphics chip is capable of

running resolutions such as 800 x 600, when these displays are added to

the monitor. The standard resolution is set to 640 X 480.

3.2 Functional Description

The VGA subsystem is designed to optimize the Bitblit operation, which

allows for quick updates of the screen. This is accomplished by writing

images to non-viewable areas of video memory before they are needed and

copying them to the screen on demand. The copy function is performed by

the VGA controller.

3.3 Video Output

The Graphics Subsystem provides output to an internal flat panel display,

while simultaneously providing the same output for a remote analog

display. The remote display signals are available on the docking station

connector and can drive a standard VGA monitor. The CRT interface uses

three 8 bit DACs for its three color outputs. The front bezel interface is

digital and contains 6 bits for each color.

Figure 2-5 DSP Subsystem

4 DSP Subsystem

The monitor uses a DSP for preprocessing of oversampled data (see

Figure 2-5). The DSP is a specialized microprocessor that executes high

speed repetitive functions such as digital filters. The DSP acquires data

from the incoming serial pod comm data streams. The data sent to the DSP

is selected by the control words in the pod com memory buffer. Typically

only high acquisition rate data is sent to the DSP.

The DSP has two other communication ports both of which can access the

internal 32Kword memory. The IDMA port is used to DMA data to and from

the common memory. Bus sizing logic converts the DSP 16 bit port to the

32 bit FRONT END bus. During initialization this path is used to download

code to the DSP. The main processor takes control of the DMA port during

this time. Once the system is operational the DSP takes control of the DMA

controller by using its I/O port. The I/O port is a dedicated 8 bit path into the

main FPGA, which allows the DSP access to the DSP DMA controller as

well as other internal FPGA registers, including analog out and QRS sync.
