Functional Description: Basic Information

Basic Information

The block circuit diagram of the entire instrument in Chapter 1, “Block Circuit Diagram of Entire Instrument” and the functional blocks of circuit diagram sheets (P-plans) describe the individual functional blocks.

Functional Description: Switching Power Supply

Switching Power Supply

The switching power supply generates the fundamental device voltage for the PCB Control CS_CI and for the PCB NC Battery Charge. It has the following input specifications.

Input voltage range: 85 … 264 Vac

Line frequency range: 47 … 65 Hz

The output voltage is +26.5 Vdc, the maximum load is 1.5 A.

Functional Description: PCB NC Battery Charge

PCB NC Battery Charge

The MAC™ 1200 resting ECG analysis system can operate on battery power. With a new, fully charged NC battery, up to 50 ECGs can be recorded in Automatic (12-lead) mode.

The PCB NC battery charge controls and monitors the charging process, depending on the status of the battery and the status of the device.

Charging Circuit for the NC Battery

An integrated charging device is used to charge the battery. During charging, it monitors the battery voltage function and switches over from rapid charging to trickle charging.

Applying the line power to the MAC™ 1200 resting ECG analysis system, or insertion of the battery activates the charging circuit. During a recording, the charging current is reduced. In standby mode, a depleted battery is fully charged within 4 hours.

Functional Description: PCB NC Battery Charge

Battery-Dependent Device Behavior

Depending on the status of the battery and the status of the device, the following behavior occurs.

Table 1. Battery State

State 1 Battery depleted, line power supply is connected up

Battery charged in rapid mode; when fully charged, switchover to trickle charging.

State 2 Battery full, line power supply is connected up

Battery charged in rapid mode for some minutes till the charging circuit recognizes battery full, then switchover to trickle charging.

State 3 Battery depleted, no line power supply, device is switched on

Device inoperative.

State 4 Battery full, no line power supply, device is switched on

Device fully operative. When battery is almost depleted, the LEDBAT signal is activated to indicate that the device should be charged by connecting to the line power supply. If the operation is continued without line power, MAC 1200/ 1200 ST will shut down itself when a minimum level is reached to prevent the battery from a excessive discharge.

State 5 Battery depleted, line power supply is connected up, device is switched on

Battery is charged in rapid mode, device is fully operative, including recording. During recording, the charging current is reduced. If a lot of recordings take place in this phase, the battery is not fully charged within 4 hours.

Functional Description: PCB Control CS_CI

PCB Control CS_CI

The PCB Control CS_CI is the main board of the MAC™ 1200 resting ECG analysis system. The main board accommodates the control functions of the device, except the line power supply and the NC batterycharging controller.

Generation of Internal Power Supplies

Logic Power Supply +5 V and +3.3 V

The processor core and the memory is a fully +3.3 V design. The interface functions to display, to RS-232, to the printing unit and to the ECG acquisition unit are supplied with +5 V.

Both the +3.3 V and the +5 V are generated separately by a clock-rated voltage controller. By using the “adjustable version” of the voltage controller, both supplies are based on the same voltage controller. The output voltage is determined by appropriate dimensioning of the voltage divider at the feedback input of the voltage controller.

Standby Supply +5 VSTB and +3.3 VSTB

The standby supply + 5VSTB supplies the ON/OFF Control, the

+ 3.3 VSTB buffers the patient ECG memory when the device is turned off. Both supplies are generated together from one low-power linear regulator with low quiescent supply current.

Analog Supply +12 V

+12 V is used for the heating control and temperature monitoring of the printing unit, which requires only a current of a few milliamperes. This supply is generated by a linear regulator with feedback input.

FPGA Power Supply +2.5V +1.25V

+2.5 V is the auxilliary source of power and +1.25 V is the main power supply for the FPGA internal logic. These voltages are generated by Dual Output Low Dropout Regulator.

Functional Description: PCB Control CS_CI

Switch On/Off Circuit

The Switch On/Off circuit consists of the On/Off control and the Voltage control.

The On/Off control switches the device on or off by switching the device supplies +UVERS and +USUPPSW. The On/Off control is supplied from the +5 VSTB.

Device On Sequence

The transition from device Off state, or Standby state when line power is connected, to device On state can only be activated by pressing the On/ Off button.

Device Off Sequence

The transition from device On state to device Off state or Standby state when line power is connected can be achieved as follows.

Pressing the On/Off button.

When the control core activates the signal DEV_OFF.

When the voltage control applies the signal REG_OFF_, because the battery voltage gets too low during battery operation.

The Voltage Control controls the battery voltage during battery operation.

The signal BATT_LEV2 indicates that the battery charge has gone down, and the device should be connected to the line power soon.

The signal BAT_LEV1 indicates that the battery has been discharged almost completely, the device should be connected to the line power immediately, otherwise the device will shut down within few minutes.

If battery discharge is continued without connecting to the line power, the signal REG_OFF_ is activated and the device is switched off.

Functional Description: PCB Control CS_CI

ECG Recording and Front-End Processing

The patient input is classified as being cardiac floating and is defibrillation-proof.

The patient leads are connected with a 15-pin connector with a special form for the specified and released patient cables for the MAC™ 1200 resting ECG analysis system.

The main element of the ECG recording and front-end processing is a set of chips comprising 3 ASICs. Pace detection is realized by a separate circuit.

Every disconnected electrode is detected by a special AC measurement, which allows higher impedance between electrode and patient.

N common-mode compensation ensures suppression of interference, at the same time serving to improve the in-phase suppression of the input electrodes.

To protect patients, the ECG recording and front-end processing are assembled as floating components. Digital signals from and to the controller core are transmitted via opto-electronic couplers. The floating supply ±5 V is generated by an isolated flyback converter from the +5 V logic power supply.

Functional Description: PCB Control CS_CI

Controller Core

The actual core comprises the Motorola Power PC MPC855T, which contains the following integrated components.

Chipselect logic

DRAM controller

SCC and SMC for RS-232

SPI interface

I/O ports

Real-time clock counter register

In addition, the MPC855T contains a JTAG port with test and programming capabilities.

The MPC855T has the following additional power supplies.

VDDSYN, filtered from the +3.3 V logic supply, for the clock generation.

KAPWR, generated from the +3.3 V logic supply or from a battery when device is off, used for buffering the RTC Counter Register.

The clock generation for the MPC855T is realized by a quartz oscillator with 32.768 KHz. The system clock CLOCKOUT is adjusted with the internal PLL register. The system frequency is 25 MHz.

The watchdog/reset generation is implemented separately in an integrated system monitoring chip. It has the following functions.

Power-up reset for the MPC855T when the device is switched on.

Voltage monitoring of the +3.3 V and +5 V with reset generation.

Watchdog

Switchover to battery supply for patient ECG memory when device is switched off.

Signal for access protection for patient ECG memory when device is switched off.

Functional Description: PCB Control CS_CI

The Reset Configuration defines startup conditions like boot port size and clock generation source.

Four LEDs indicate the device status in addition to the following.

The control register comprises device control signals to switch off the device, control battery charging and display control signals.

The status register contains information on the device hardware configuration and the state of the battery charge.

Real Time Clock

With software version 6, two options for the real time clock are supported. The software checks for an external real time clock chip (X13 on PWA control). This chip is available with Index G of PWA Control CS_CI and Index F of PWA Control CS_C.

If the external RTC is found, it will be used for the clock function. If not, the internal clock of the MPC855T will be used. The external RTC is more accurate than the internal one. Both clocks are buffered by the voltage KAPWR.

The complete memory of the MAC™ 1200 resting ECG analysis system is located on the PCB Control CS_C(I). The software of the device can be loaded through the JTAG port during the production process, or for service purposes with the appropriate programming software through the RS-232 interface.

Program Memory

DRAM

Patient ECG Memory

Configuration Memory

The configuration memory is part of the program memory Flash. With special hardware and software protection facilities, write access to the Flash is only possible in the defined configuration memory of the Flash. Thus an external configuration memory like an EEPROM is not required.

LCD Graphics Display Interface

The LCD controller is now implemented in FPGA.

Controller Interface

For the digital control signals, delivered from the MPC855T, only an output driver is required.

Functional Description: PCB Control CS_CI

LCD Power Supply

The LCD power supply VEE of –23 V is generated from the +5 V logic supply. The generation starts after HRESET_ becomes inactive to ensure that the logic supply of +5 V first is applied to the display.

Adjusting Contrast

Contrast adjustment of the display is accomplished with the contrast voltage V0. The level of V0 is controlled with the PWM signal BLCD_CONTR from the timer module of the MPC855T.

In addition, the contrast voltage is temperature compensated.

Backlight

The LCD backlight converter for the CCFL tube is located on the PCB Control CS_CI too. The backlight converter is generated from the +5 V logic power supply.

The signal BLCD_ENBA switches the backlight on or off. The user can define the backlight active time in the configuration menu.

Functional Description: PCB Control CS_CI

Keypad Interface

The keypad interface contains the control register for 8 keypad columns and the receiving register for 7 keypad rows, and the control signals for the status LEDs: LED_LIN, LED_BATT_, LED_START, and LED_STOP.

Using the matrix of 8 x 7, up to 56 keypads can be detected.

Identification of the key pressed is as follows.

The controller activates a column, activation is via low-level, then the row-register is read to identify the pressed key by a low-level. This procedure is repeated with the next column, till all columns have been activated.

Printhead Control

The printhead controller takes on the complete control of the 216-mm thermal printhead with a line width of 200 mm.

The output rate to the printhead is 1000/second. The resolution in the

Y-direction is 8 dots/mm, in the X-time axis up to 40 dots/mm.

Thermal Printhead Dot Control

The MPC855T prepares a complete dot column and sends it to the FIFO. An FPGA reads out a complete column of the FIFO and generates the digital control signals for the printhead, which are shifted in series.

The duration of heating a dot column is defined through the pulse width of the PWM Signal HEAT that is generated from the FPGA too.

In addition, the duration of heating a dot column is influenced by the thermal printhead monitoring.

Functional Description: PCB Control CS_CI

Thermal Printhead Temperature Monitoring

The thermal printhead temperature monitoring measures the temperature of the thermistor, located on the printhead. A constant current source effects a temperature-dependent voltage drop.

If a printhead temperature of 55°C is exceeded, the signal REC_OVHEAT is activated and the heating of the printhead is prevented by disabling the signal STROBE.

Only when the printhead temperature drops below 50°C is the signal REC_OVHEAT disabled and the heating via the signal STROBE reenabled.

In addition, a continuous reduction of the heating duration occurs with increasing printhead temperature, resulting in a regular typeface throughout the entire temperature range.

Motor Control

Paper transportation for the speeds 5 mm/s, 25 mm/s and 50 mm/s is driven by a stepping motor. The stepping motor is controlled by an integrated stepping motor driver circuit. The current for the motor is adjusted by the sense resistors of the stepping motor driver.

For the speed 5 mm/s, the motor current is reduced, triggered by the signal LOW_SPEED.

The motor speed is controlled by the frequency of the signal RECTMR_STEP, which is generated by the timer unit of the MPC855T. The driver circuit is enabled by the signal REC_MOTEN, the driver is powered from +22.5 V.

Functional Description: PCB Control CS_CI

RS-232 Interface

The MAC™ 1200 resting ECG analysis system has an RS-232 interface accessible with a 9-pin Sub-D connector.

Except for the RS-232 driver chip, the interface is integrated into the control core of the MPC855T.

The interface has the following attributes.

Hardware handshake with the signals RTS and CTS.

Software handshake with XON/XOFF.

Transmission speeds from 4800 … 57600 Baud.

Maximum input voltage range: ±15 V.

Minimum driver output voltage: ±5 V.

Maximum ESD interface protection: ±10 kV.

The MAC™ 1200 resting ECG analysis system provides a remote start input on the RS-232 interface. The MAC™ 1200 resting ECG analysis system US device additionally provides a modem power supply output on the RS-232 Interface.

Buzzer

The buzzer is an integrated signal generator with fixed frequency, directly operating from the +5 V logic power supply.

Activating and deactivating is controlled with the signal SPEAKER.

Functional Description: Modem Supply

Modem Supply

PCB Modem Supply CS_M is no longer used in MAC1200 units equipped with -003 boards. The modem power supply is now integrated onto the main board (2018357-003 and 2013503-003). The main board generates a supply voltage of +8 Vdc, to operate a special GE modem direct on the RS-232 interface on the MAC 1200 device without the need for an external power supply for the modem.
