Mindray DC-26 User Manual

Hardware Principle 4-5
 Multifunction FPGA on the back-end of the main board is to implement the
REMOTE port on the IO interface board.
 The CPU module implements interfaces including USB, Ethernet and VGA on
the IO interface board
 System monitor circuit connects Multifunction FPGA though smbus.
 Multifunction FPGA communicates with ARM by serial port to control
transmission high-voltage, and also implements ARM update by serial port.
 FPGA on the power supply module implements the system power on/off by the
switch signal.
 Standby indicator, AC present indicator and working status indicator on the
control panel are output by FPGA.
 The control panel implements communication with CPU module by USB.
 The CPU module output the audio signals to the IO interface board..

Figure 4-5 Principle Diagram of IO interface board
IO interface board connects to the main board via connectors in order to implement
the user interface function. Main functions include:
 Transfer signals from main board to IO Rear board, control panel, monitor, ECG
board and etc.
 Power the display module, DVD-RW, HDD, control panel, ECG board and etc.
 Support connections of all signal ports on the IO Rear board.
 IO interface board supports signals of Video and S-Video, the two channels of
which are obtained by Multifunction Module including Video Encoder and
Multifunction FPGA.
