2.2. CPU BOARD

Overview

 The CPU board is fitted to PILOT anaesthesia 2 version, around a 80C32 microprocessor used in

open mode. It concentrates all the peripheral devices directly connected to the 80C32 bus. It is
connected to the power supply board by a 40 contacts ribbon cable and to the display board by
fixed connectors. It forms a single unit, with the display board, which is fixed to the front panel.

 The CPU board uses CMOS technology in order to minimize power consum ption.
 Current used: 5 Volts 80 mA maximum.

2.2.1. Functional description

The CPU board comprises six functional units:

q Ram rom decoding processor
q Reset WATCH DOG
q Parallel port extensions

display/keyboard interface,
motor interface,
sensor interface.

q SPI BUS
q Asynchronous serial link
q Optical sensor

2.2.1.1. RAM ROM decoding processor
Decoding is carried out by an IC3 80C32 circuit, running at 12 MHz, clocked by Q1. It is used in open

mode, with the EA*/VP line connected to GND.
Address/data de-multiplexing is carried out by a 74HC573 U3.
On this BUS are implemented:

32 Ko static RAM U6
27C010 128 Ko (extension to 512 Ko) U4

2.2.1.2. Reset watch-dog
The RESET WATCH-DOG module comprises two TL7705 U10 and U11 circuits.
Operation: the U10 circuit generates RESET signals, active at 1, for the processor and the UART; RST*

active at 0 generates RESET signals for the other peripheral devices.
The signals are activate in two cases:

q when the system is powered up,
q as soon as the WATCH-DOG circuit is triggered. It remains active until the power is turned off.

2.2.1.2.1. Reset at power-up

The TL 7705 circuit guarantees the minimum duration of the reset lines, in the active state, once the +
5V voltage has exceeded the circuit operating threshold (4.75V). It returns to the active state, if the + 5V
voltage drops below the threshold or if the RESTIN* (U11.2) is at 0. The line is driven by the WATCH­DOG module.

The duration of the reset, in the active state, at power-up is set by the C10 capacitor 220nF 100 ms.

Page : 16 NT 0818 Rev.A1

2.2.1.2.2. Watch-dog

The WATCHDOG circuit comprises the following elements: U10, U11, C12, D2, D1, R4, C11.
When powered up the capacitor C12 is charged by the U10 circuit, via diode D1.

The charge is maintained at a threshold of over 1.5 V during operation.
The software writes, every 1 ms.This writing generates a 5V/1µs impulse on the U7.10 output, which re-

charges the capacitor C12 via a high pass peak detector circuit made up C8, D3, D2. The C12 capacitor
discharges in resistor R4.

When the software stops, the capacitor C12 completely discharges. The U11 RESTIN* line falls to 0 and
the RESET signals are activated, stopping all syringe-pump control operations in the inactive state.
Fault signals, the blinking FAIL diode and the continuous BUZZER are stuck in an active state.

WATCH-DOG trigger time is less than 400 ms.

2.2.1.3. Keyboard/display interfacing

2.2.1.3.1. Display registers

The display system is made of LED’s and of a 2 lines of 20 characters LCD graphic screen.The U7 cir­cuit allows to address the matrix of the LED’s, the U8 circuit allows the writing and reading in the display
controller.

The LED’s matrix are DIG0 to DIG7 and SEG0 to SEG7.
The FAIL LED shows the device is failed, the command is inverted to be active by default at RESET. It

is active at 1 on the display board. The FAIL diode is out of the matrix to be able to light on when the
micropossor does not work.

2.2.1.3.2. Buzzer

The BUZZER command is inverted and controls the transistor, T3, which is mounted as a common
transmitter. Working in parallel, the transistor collector drives the BUZZER on the display board and the
nurse call relay on the motor control power supply board. After starting the pump, the BUZZER is acti­vated for added safety.

BUZZ signal: J5 pin 6 and J3 pin 24 50 mA 6.75 Volts maximum.

2.2.1.3.3. Keyboard register

The keyboard is based on a 6 x 3 matrix, with 2 separate keys - TON and TOFF - with 1 common
point (GND). They turn power ON and OFF respectively and are connected to the display board. TON
and TOFF signals only transits via the CPU board.

The columns of the keyboard are driven by the same signals as the columns in the display matrix, thus
facilitating simultaneous keyboard and display monitoring. Register U15 reads the status of the three
keyboard lines, LIG1, LIG2 and LIG3 in order to check whether a key has been activated.

2.2.1.3.4. Motor control register

The U12 motor control register generates 4 motor phase signals, A,B,C and D, the I current control sig­nal, the motor rotation opto control CDOPT1 signal and the BOOST BOOSTER control signal.

2.2.1.3.5. Sensor status register

The U16 sensor status register reads the microswitch digital sensors and the syringe pump opto switch.

NT 0818 Rev.A1 page : 17

2.2.1.4. SPI bus EEPROM
The SPI bus is synchronous series communication bus using various peripheral circuits. The SPI bus is

driven by the 80C32 ports.
The PILOT anaesthesia 2 syringe pump has 2 peripheral devices on the SPI bus:

q The EEPROM 2 Ko 24C16 U12 located on the CPU board.
q The MC 145053 analog/digital converter located on the motor board.

This bus has 2 communication lines: 80C32 (see electrical diagrams)

Micoprocessor Ports

CLK clock generated by the microprocessor P 1.1
SI peripheral to processor data (input) P 1.2

2.2.1.5. Asynchronous serial links
The PILOT anaesthesia 2 syringe pump is fitted with two asynchronous serial links.

RS232 option line 1
TTL configuration serial link line 2

2.2.1.5.1. RS232 serial link

The RS232 serial link is implemented using the U8 SCC2691 circuit, which controls asynchronous com­munication, and RS232 interface circuit which is located on the motor power supply board.

The circuit is clocked by quartz Q2 at 3.6864 MHz. It includes a programmable baud rate generator. It
generates interrupts on the ITRS232 line connected to the processor at INTO.

The SCC2691 is on the microprocessor bus. It drives the RXD1 receive data signals on J3 (pin 34) and
TXD1 transmit data signals on J3 (pin 35).

The RS232 option is reserved for dialogue with the host computer responsible for monitoring or control­ling the system.

2.2.1.5.2. TTL serial link

The TTL serial link is driven by the serial link controller inside the microprocessor. It uses one of the
internal timers to generate its baud rate, from the basis of the processor 12 MHz clock. The serial link
drives the TXD2 transmit data and RXD2 receive data lines. The input and output lines are buffered by
the U9 74HC14 buffer trigger inverter circuit.

The lines are available on J3.

TX2 J3 pin 33
RX2 J3 pin 34

This serial communication line is reserved for PILOT anaesthesia 2 software configuration and, when
appropriate, for connecting an external MASTER module.

2.2.1.6. Opto switch sensors
PILOT anaesthesia 2 syringe pump opto switch sensors are for piston pressure and syringe body pres-

ence and motor rotation.
The syringe body opto switch interface is located on the CPU board. It is implemented using transistors

T1, T2 and T3. Resistor R9 limits current in the diode to 8 mA.

Page : 18 NT 0818 Rev.A1

2.2.1.6.1. Opto switch body syringe measurement.

q Note: The CI opto and the obturator are specific to the PILOT anaesthesia 2 equipped with

"flange detector" and are not compatible with previous versions.

q 2 opto devices allow to detect 2 syringe sizes: 60 cc and 20 cc.
