M - Trigger Mode
Trg 1 [Always] ->
The trigger mode option allows the user to decide what condition should be met before sending
the data. The following shows the options.
Off: Conditional transmissions are disabled. Data will only be sent when forced.
> Set Pt:
Greater than the set point. Send data IF the data is greater than the Set Point. This
could be used to send data due to high water.
< Set Pt:
Less than the set point. Send data IF the data is less than the Set Point. This could be
used to send data based on the battery level starting to drop.
Delta: Send data based on a change in data. Data is sent IF the data changes more than the set
point value. The change can be either an increase or a decrease. This could be used to
track a changing stream or rainfall.
Always: Always send data. No conditions have to be met, data is sent automatically on each
scan.

T - Trigger Point
Set Pnt 1 [0.0000 ]->
The “Trigger” or “Set Point” option is used to enter the value used to compare with the actual
data to see if data should be sent. The section above describes the type of conditions that can be
used to trigger a transmission. For example, if the user wanted to send data based on the stage
exceeding 10 feet, then the trigger mode would be set to " > Set Pt " and the trigger point would
be set to 10.0. Now at each scan interval that the stage was at 10 feet or greater, the trigger
condition would be true and data would be sent.

R - Reset Point: 0.00
Rst Pnt 1 [0.0000 ]->
The Reset Point is a point that the user defines to reset the trigger mode to prepare for another
trigger. From the example above, the trigger was set when the stage went greater than 10 feet, if
the reset point was set to 5 feet, the trigger would not be reset and ready for another trigger until
the stage goes to or below 5 feet.
