System Overview Theory of Operation System Overview The boards and their interconnections are shown in the following figure. The CPU board, which has overall control of the entire system, contains flash EPROMs containing all the system software. The software for the Combined Interface Board (if one is fitted) is loaded from this ROM area.The signals from the transducers receive some analog conditioning on the Front End Board and are then digitized on the CPU Board.
Booting and Self Tests Booting and Self Tests The monitor carries out a basic test every time it is switched on, and then at periodic intervals while it is on. There are two types of test: Programs that check the hardware on each board. Programs that carry out checksums on the individual portions of code that are loaded from the Flash EEPROMs.
Booting and Self Tests The Combined Interface Board and the Modem Interface Board both have processors that test the interface board once the DMA control logic has been checked. The CPU Board boots a test program from the ROM to the on-board Digital Signal Processor (DSP) program RAM.
Front End Board Front End Board − M1351A The Frontend board (M1353-66501 single, M1353-66511 - dual) contains the analog (M1353-66501 circuitry for measuring all the possible parameters of the M1351A. One IC on the board provides the US timing and window control. Each type of transducer has a specific mode M1353-66511) resistor which is recognized by the M1351A when the transducer is connected to an input socket.
Front End Board controls the ECG. Each type of transducer has a specific mode resistor which is recognized by the M1353A when the transducer is connected to an input socket. In this way, different types of transducer can be used without the user having to recalibrate the system. The marker cable is also connected to the Frontend Board.

A real-time clock, battery-backed and power-fail protected. The processor has access to all clock registers. The multiplexer ASIC contains a watchdog function which monitors the operation of the microprocessor and restarts the system if it is not served at a constant rate.
Display Board (M1350-66520) Display Board (M1350-66520) pegdbd40 The display board consist of the following main parts: Keys Display Controller Backlights LEDs Signals at the keys are fed to the recorder board via the ribbon cable and are sampled by the controller.
Recorder Interface Board (M1353-66510) Recorder Interface Board (M1353-66510) apegblk3 The Recorder Board provides the interfaces to the recorder and the display. The recorder interface consists of: The parallel/serial converter for the thermal array data. A heating timer to control the heating pulse for the thermal array. The voltage from a thermistor on the thermal array is A/D converted and the CPU programs the heating timer with a value which compensates the ambient temperature.
There are two boards available; the M1353-66531 and M1353-66531E. Both boards Interface Board process analog input signals from Philips telemetry systems (for example, the M1310A), and send heart rate, Toco, mode and status information to Philips OB systems, such as OB TraceVue . Both boards receive signals from: A Barcode Reader.
Interface Boards Figure 6-3 Combined Interface Board M1353-66531(E) Both the M1353-66531/66531E boards include the following sections: Analog Signal Filter Section: An analog input for FHR, US LF or DECG, with low pass filter and variable gain amplifier. An analog input for TOCO/IUP with low pass filter. The analog signals are fed to the A/D convertor on the CPU Board.
Interface Boards System Section: This section is controlled by an 80C51 microcontroller. The communication between this controller and the CPU on the CPU board is done by dumps every 250 msec. The CPU also boots the software for the 80C51 controller into the ROM during startup.
The interface board enables the fetal monitor to form part of a remote monitoring system, consisting of: A Transmitter (Series 50 A/IP Fetal Monitor with Modem Interface Option). Receiver (OB TraceVue system). The system also receives information from: A Barcode Reader.

Introduction Modem Interface Module Introduction The modem interface module allows fetal trace information to be transmitted from a Series 50 A/IP-2 Fetal Monitor to a receiver that is part of an OB TraceVue system. The modem interface module (with the addition of an approved PCMCIA modem) enables fetal traces to be transmitted over a standard telephone line.
2. If necessary, connect a phone-line adapter and secure it to the module with cable fasteners or Velcro-type strip. 3. Checking it is the correct way up, insert a Philips approved PCMCIA card modem into the card connector port (3), pushing it until it is slotted in position.
Connecting Peripheral Devices Barcode Reader Once the barcode reader is installed, check that it is operating correctly. See the User’s Interface Guide for your monitor for instructions on how to use the barcode reader. 1. Use the barcode reader to scan Test Barcode 1 and then Test Barcode 2 from the barcode sheet.
This RS232 Serial Interface connection enables the monitor to be connected to a PC (no Interface Philips software supplied). The connector is a female D-type, 9-pin subminiature connector with a baudrate of 9600. The following table lists the signals at each pin.
Entering, Storing, and Transmitting Data Entering, Storing, and Transmitting Data Actions associated with the storage and transmission of fetal trace information are initiated by using a barcode reader. Use the reader for: Entering the receiver phone number. Entering the patient phone number. Entering the patient ID.
Entering, Storing, and Transmitting Data Setting the To enter the Receiver Phone number (maximum of 20 characters): Receiver Phone 1. Scan the Receiver Phone Barcode. Number 2. The telephone network will use a Pulse or Tone based switching system. Determine which is used (consult your local phone company for information), then first enter the appropriate Pulse or Tone barcode before scanning the digits of the Receiver Phone number.
2. The 0 displayed then clears. The normal transducer display is given and two flashing decimal dots (three in the case of the Series 50 A Dual Ultrasound model) flash on and off (2Hz) indicating that storage is taking place.
Entering, Storing, and Transmitting Data 3. The decimal dots continue to flash until storage is stopped. Then the dots are displayed continuously to indicate that a trace is stored in memory. If the barcode Start Storing is scanned and the memory is not empty, the fetal trace stored in the memory is briefly displayed (in minutes).
Acknowledge the error message by scanning the barcode Display Memory or by pressing a key, such as 2. The error message Err 77 clears and two (three in the case of the Series 50 A Dual Ultrasound model) decimal dots are permanently displayed, indicating that fetal trace data is still stored in the memory.
OB TraceVue in the countries listed. As modem technology changes rapidly, we recommend that you consult the Philips Technical Marketing information pages "SoftServer" on the Intranet at http://www- softserver.germany.agilent.com for up to date information on modem compatibility.
List of Parts 1. Scan the “Start Modem Setup” barcode. Programming a Modem Setup 2. Use the barcodes to enter the setup according to the operating manual of the modem Sequence you are using. 3. Scan “Finish Modem Setup” to enter the modem setup you have just programmed. 4.
Err 70 and/or Err 77 messages. In the event of a power fail , the normal Series 50 A/IP features apply, in addition to these: Fetal trace storage can not be continued after a mains failure. If the length of the stored trace following a mains failure is not large enough, clear the memory and record a new fetal trace.
If there is a problem with the telephone line contact the telephone service supplier. 4. Check that the PCMCIA card modem is approved by Philips and that it and the connections between the modem and the telephone wall jack are correctly fitted in accordance with the telephone line supplier and the modem manufacturers recommendations.

Safety Information Safety and Environment Safety Information Follow these guidelines for maximum patient safety: Protective Earth Check each time before use that the Monitor is in perfect working order and properly grounded. Warning Shock hazard: any interruption of the protective earth grounding will cause a potential shock hazard that could result in serious personal injury.
Environment The Monitor is designed to fulfill safety requirements according to IEC 60601-1, UL 544 and CSA C22.2-601.1-M90. It is not intended to be used for direct cardiac application and it is not defibrillator-protected. The external Toco transducer (M1355A) is equipment type B M1351A: Connecting the transducer to the Toco channel results in B condition.
Declaration for details. EMC Testing During the test program the monitor was subjected to international standard and Philips proprietary EMC tests. During most of the testing no anomalies were observed. Some reduced performance was observed with the IEC 801-3 Radiated Immunity and IEC 801- 4 Fast Transient/Bursts Immunity tests.
4. Add external attenuators. If EMI becomes an unusually difficult problem, external devices such as an isolation transformer or a transient suppressor may help. A Philips customer engineer can assist you in determining the need for external devices.
Upgrade Key Introduction This section tells you how to use an upgrade key to upgrade the software of the Philips Series 50 A and IP-2 fetal monitors. Option C01 (adding twin ultrasound capability), applies only to the 50A . Upgrade Procedure 1.
7. Switch the monitor off and then on: it will perform the power-on self-test. If an error message is displayed, contact Philips. If “ -8 -” is displayed, the upgrade was not successful. Try the upgrade again from the beginning.
