Equipment overview: Theory of operation
I
2
C bus
The I
2
C bus is used to interface to the Real Time Clock and the Serial
EEPROM.
SPI interface
The SPI is used to program the FPGA.
Power supply
The power supply generates DC voltages necessary to power the
processor board and the communication channels (M-ports and devices
connected to TRAM-NET). It consists of a mains (AC line) PWM
converter, that creates a 16.75 output voltage bus from which two
outputs are developed. The main 16.75V output also provides external
power to the RAC, data acquisition modules, and plug-in modules.
Speaker
The speaker generates sound for alarms, QRS detection, and SpO
2
pulse
tones.
