Example (ASCII and NMEA 0183, device address 0):

0XU<cr><lf>

0XU,A=0,M=P,T=0,C=2,I=0,B=19200,D=8,P=N,S=1,L=25,

N=WXT520,V=1.00<cr><lf>

Example (SDI-12, device address 0):

0XXU!0XXU,A=0,M=S,T=0,C=1,I=0,B=1200,D=7,P=E,S=1,L=25,

N=WXT520,V=1.00<cr><lf>

NOTE

There are two different SDI-12 modes available for providing all the

functionality of the SDI-12 v1.3 standard.

The lowest power consumption is achieved with the Native SDI-12

mode (aXU,M=S), as it makes measurements and outputs data only on

request.

In the continuous SDI-12 mode (aXU,M=R) internal measurements

are made at a user-configurable update interval, see Chapter 8, Sensor

and Data Message Settings, on page 107. The data is outputted on

request.
