2.4 System Parameter
2.4.1 General
For the DPM4 patient monitor, signals are collected by modules, and the results are transferred to
the main board through the adapter board, thus to process and display the data and waveforms.
Commands from the main board, as well as the status information of modules, are transferred
through the adapter board. In addition, the adapter board adapts and changes the power supply.
The structure of the whole system is shown in the following figure.

in real time, and send the results to the main board for
processing and displaying. If necessary, the results are sent to the recorder for printing.
The parameter monitoring functions are described respectively in the following sections.
