System Overview 6 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: l Programs that check the hardware on each board. l Programs that carry out checksums on the individual portions of code that are loaded from the Flash EEPROMs. When the monitor is switched on, the initial reset generated by the power supply is fed to the CPU Board, where it is latched and passed to the other boards.
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. The DSP then runs it. The program tests the DSP and its associated components, and writes the results to the DSP RAM. The CPU reads the RAM to find out the exit status of the tests.
Front End Board Front End Board M1351A (M1353-66501 and M1353-66511) The Frontend board (M1353-66501 − single, M1353-66511 - dual) contains the analog 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 resistor which is recognized by the M1351A when the transducer is connected to an input socket. In this way, the user can be warned if a wrong transducer is connected.
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.

The FOCUS ASIC on the board provide the US timing and window control, and 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.
Power Supply Board (M1353-66502) Power Supply Board (M1353-66502) The Power Supply Board operates as a linear regulated power supply with rectifier, capacitor and regulator. It generates the following voltages: Regulated dc: ±12V, +5V and +24V Unregulated dc: +7V to +12V ±12V and +5V have an electronic short circuit current limit.

Introduction A 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. The receiver software displays the trace information, allowing it to be reviewed, printed and stored.
Connecting Peripheral Devices Connecting Peripheral Devices After you have fitted the module, connect the following peripheral devices: 1. Connect the barcode reader to the module’s RS232 interface socket (1). (The auxiliary serial port (2) allows connection to a PC but has no Philips software support.) 2. If necessary, connect a phone-line adapter and secure it to the module with cable fasteners or Velcro-type strip. 3.
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. 2. Check that TEST OK5 is printed on the paper. If it is not, switch the monitor off and on, and repeat the test. If it is still not printed, connect a new barcode reader.
Connecting Peripheral Devices RS232 Serial Interface This RS232 Serial Interface connection enables the monitor to be connected to a PC (no 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: l Entering the receiver phone number. l Entering the patient phone number. l Entering the patient ID. l Clearing stored fetal trace data. l Starting storage of the patient’s fetal trace. l Displaying the amount of minutes of fetal trace data stored in the memory.
Entering, Storing, and Transmitting Data Setting the Receiver Phone Number To enter the Receiver Phone number (maximum of 20 characters): 1. Scan the Receiver Phone Barcode. 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. 3.
Entering, Storing, and Transmitting Data Keep Patient Data after Transmission or When Clearing Trace Memory If you use the Monitor regularly for the same patient, you will probably want to retain her patient identification data, so you do not have to reinput it each time you send a trace. Scan Keep Patient Data after Transmission once.
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). But since the memory already has data stored, the Start Storing command is ignored.
PCMCIA Card Modem If transmission problems occur, the fetal monitor automatically attempts to resend the remaining trace (up to three times). If these retries fail, and data transmission stops, you will see the error message ERR77 and hear a triple beep tone (beep, beep, beep!). The fetal monitor will make no more attempts to resend data. Acknowledge the error message by scanning the barcode Display Memory or by pressing a key, such as . You can try to send the remaining trace at a later time.
PCMCIA Card Modem Modem Compatibility To ensure compatibility with local telephone systems, modems must be obtained locally. The following table shows which modems are currently suitable for remote trace transmission to an obstetrical information surveillance system such as 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://wwwsoftserver.germany.agilent.

Safety Information B 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. M1353A: Connecting the transducer to the Toco channel results in CF condition.
Spillage Spillage If liquid enters the monitor, you must cease using it immediately. Contact an authorized engineer for a safety inspection. Electromagnetic Compatibility The electromagnetic compatibility (EMC) validation includes testing performed according to the international standard for EMC with medical devices. See the Manufacturer’s Declaration for details. EMC Testing During the test program the monitor was subjected to international standard and Philips proprietary EMC tests.
Electromagnetic Compatibility Avoiding Interference When electromagnetic interference (EMI) is encountered there are a number of things that can be done to mitigate the problem. 1. Eliminate the source. Possible sources of EMI can be turned off or moved away to reduce their strength. 2. Attenuate the coupling. If the coupling path is through the patient cables the interference may be reduced by moving and/or rearranging the cables to a different location of the monitor.
C 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. Disconnect all transducers (and telemetry) from the monitor. 2. Switch on the monitor. 3. Plug the upgrade key into the service socket (see Figure 1-1 on page 5) on your monitor (if applicable, first remove the little plastic cap on the service socket).
Upgrade Procedure 6. Stick the feature label to the front of the monitor, as in the example below: A: Fetal Movement Profile B: Dual Ultrasound 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. If “--- --- ---” is displayed, the new software is installed and checked.
