7.1 System Principle Block Diagram

FTS-3 system consists of two US-T transducers, one TOCO-T or TOCO-E transducer and one
base station. Place the transducers back into the docking slot for charging when they are not in
use. When the transducer is taked up from the base station, it starts to work.
The transducer has a batch of serial ports and battery input. When the transducer is put in the
docking slot, the transducer communicates with the monitor through the serial port and tranmit
the related messages. When the transducer is taked up, it communicates with the monitor
wirelessly and is supplied by its battery inside.
The system principle block diagram goes as follows.

7.1.1 Main Board
The main board of the base station acts as the center of the whole system and is responsible for
receiving the wireless data, controlling LED indicator, communicating with the bedside monitor
and modular control.
The parameters of this main board are listed below:
