Digital Signal Processing
The Digital Signal Processor (DSP) contains the central processing
unit (CPU). As the source of all monitor activity, the processor is
responsible for all of the monitor's high-level functions, including
the following:
 Scanning the sensor and float switch inputs to retrieve data for
processing and storage
 Maintaining the monitor time and date
 Performing power management
 Transmitting the stored and current data to the user's PC
 Initiating event and alarm notification
The DSP allocates portions of memory to firmware (permanently
stored software) and data storage. A seven-segment (SS) light-
emitting diode (LED) located on the board indicates the current
monitor communication and operational activity. The DSP also
