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=WXT510,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=WXT510,V=1.00<cr><lf>
[L] = RS-485 line delay: 0 ... 10000 ms
Defines the delay between the last character of the
query and the first character of the response message
from WXT510. During the delay, the WXT510's
transmitter is disabled. Effective in ASCII, polled
and NMEA 0183 query protocols. Effective when
RS-485 is selected (C = 3).
[N] = Name of the device: WXT510 (read only)
[V] = Software version: for example, 1.00 (read only)
<cr><lf> = Response terminator
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 93 . The data is outputted on
request.
