Continuous Measurement (aR)

The device can be configured so that all the parameters can be requested
instantly with the command aR instead of the two phase request
procedure of commands aM, aMC, aC, aCC + aD. In this case the
obtained parameter values are are those from the latest internal updating
(for setting of update intervals, see

Chapter 8, Sensor and Data Message

Settings, on page 93

).

Command format: aRx!

NOTE

For using Continuous measurement commands for all WXT510
parameters (wind, PTU, precipitation, and supervisor) the respective
protocol must be selected (aXU,M=R).

The M=S selection requires use of aM, aMC, aC, aCC + aD
commands, only the precipitation data can be retrieved continuously
(using aR3 command).
