touchscreen driver
external display VGA drive
audio driver
integrating the alarm lamp
integrating the light sensor
wired network communication
wireless network communication (through the Wi-Fi module)
USB driver
real-time clock
data and configuration storage
DC/DC conversion and power switching
power management (power-on/off, status monitoring, etc.)
battery management (in-position detection, charge control, discharge control, status monitoring, etc.)
integrating the external power LED and battery LED
analog and defib. synchronization signals transfer
communication with the Dock
communication with the Modular Rack
communication with the host monitor

module
2.2.1.2 Multi-parameter Board
This board completes the basic parameter measurement functions, including:
ECG and Resp parameter measurement
SpO
2
parameter measurement (in the backboard mode, supporting Mindray, Masimo, and Nellcor SpO
2
)
NIBP parameter measurement
2-channel TEMP parameter measurement
2-channel IBP parameter measurement
isolation of parameters except NIBP from the ground
isolation of ECG from other parameters
direct output of analog signals (1-channel ECG and 2-channel IBP)
direct output of defib. synchronization signals
data interaction with the main board through the serial port
