2-6 ADS TRITON+ Manual
The processor board is the source of all monitor activity. The board
is responsible for all of the monitor's high-level functions, including
the following:
 Managing user communication with the monitor
 Controlling the timing at which the sensors fire (i.e., take
readings)
 Retrieving and storing sensor data
 Maintaining the monitor time and date
 Performing power management
 Storing the parameters required to accomplish the associated
system operations
 Transmitting the stored and current data to the user's PC or FTP
site
 Outputting a discrete signal pulse to a water quality sampler
 Displaying system power and operational status and diagnostic
codes
 Initiating event notification through alarms
 Transmits readings and signals through analog and digital
outputs and requests and receives data and status information
through analog and digital inputs
The board allocates portions of memory to firmware (embedded
software in the monitor that can be upgraded remotely) and data
storage. The board also includes the monitor clock, random access
memory (RAM), and Flash. The monitor uses RAM while taking
readings and processing the flow data. The RAM then downloads
the data to NVRAM or non-volatile memory, which is backed up by
an on-board battery. Firmware programs concerning operation are
stored in Flash.
