Technical description of the boards 5.2.1.3 Control of power supply voltages activation: Switching of the U_ALIM voltage, from which are also produced the +3.3V_TEST, +5V_TEST and +6V_TEST voltages, is carried out by means of the Q1800 switching transistor. It is controlled by the U_ALIM_ON signal resulting from the logical operation carried out from the command signals M/-A_TEST, HB0_TEST and status signal –BAT_LOW_TEST.

Technical description of the boards 5.2.2 The CPU section The CPU section contains the operating system (Linux), all associated specifications, keyboard management and display, management of signals coming from the sensors (SPO2, NIBP, Hall) and management of all inputs/outputs (peripherals). It is comprised of a Coldfire microprocessor, memory (RAM and flash) and peripherals such as the USB, the TFT controller, the clock (RTC), the sound (Buzzer) and serial connections.
Technical description of the boards 5.2.2.
Technical description of the boards 5.2.2.4 CPU The CPU is a Coldfire microprocessor made by Motorola, and it is responsible for executing the different programs (start-up, operating system and applications).
Technical description of the boards 5.2.2.7 CPLD The CPLD manages address decoding and creates the Chip Select signals which activate each periphery individually. It also manages the keyboard and rotating button signals and various command and control signals.
Technical description of the boards 5.2.2.10 Compact Flash Compact Flash is a memory containing the applications, configurations (options) and trends. It acts as the hard disk. 5.2.2.11 RTC A battery-powered DS1501 (U1000) RTC (Real Time Clock) keeps the time on the device. 5.2.2.12 USB The SL811 (U1100) USB controller enables implementation of a USB output to connect to a USB key or, potentially, to connect a printer. 5.2.2.13 Audio Alarms are generated by an AT89C2051 (U1201) microcontroller.
Technical description of the boards 5.2.2.17 NIBP power supply For the NIBP measurement, we use a CAS module. Activation of the NIBP signal _ON_5V leads to generation of the +6V_CAS voltage. The signal PUMP_5V is generated when the current consumed on the +6V_CAS voltage is high. 5.2.2.18 SPO2 For the SPO2 measurement, we use a BCI module. The analog +5Va and –5Va voltages are realised using MAX1735 (U1702) and MAX883 (U1703) voltage regulators and a 7662 (U1701) voltage converter.

Technical description of the boards 5.3 The keyboard circuits and USB connection (WSM0079…) The three circuits are part of the same flank. When these circuits are separated, a code article is attributed to each of them. These codes are as follows: - IC CLAVIER G. MAGLIFE LIGHT (CA : WSM0079B). [Left keyboard circuit] - IC CLAVIER D. MAGLIFE LIGHT (CA : WSM0079C). [Right keyboard circuit] - IC CONNEXION USB MAGLIFE LIGHT (CA : WSM0079D). [USB connection] 5.3.
Technical description of the boards 5.4 The EXTERIOR ALIM (WSM0081A). 5.4.1 GENERAL INFORMATION: The mains power supply module delivers, from the 50-60 Hz network, a rectified and filtered voltage (MAINS) which may vary, according to the current output, between 18 V and 32 V. It is designed to operate on 115 V and 230 V networks using a voltage selector integrated into the module board. The power conversion is performed using a 25 VA toroidal transformer with double windings, primary and secondary.
Technical description of the boards protection, constituted by the CTP R11, protects the limitation resistors R1, R3 against overheating in the event of short-circuiting of the filter capacitors. In addition, the MAINS output voltage is equipped with a system for rapid discharge of filter capacitors C3, C4. Its aim is to prevent prolonged presence of MAINS voltage on the module output. While the module is under voltage, the signal taken from the D2 cathode blocks the Q3 transistor.
Device modifications 6. Device modifications 6.1 Definition ECL: The ECL is the board modification index. There are two types of ECL numbering: - the first has three figures (PNN). -P : corresponds to the board version number and is incremented on each rerouting. - NN : is incremented for each modification carried out on the board. NN falls back to 00 when the P version varies. - the second has 2 letters (PN) of the board 6.2 6.3 6.
