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=WXT530,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=WXT530,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 the transmitter. During the delay, the 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: WXT536 (read-only)
[V]
=
Software version: for example, 1.00 (read-only)
[H]
=
Parameter locking
0 = Parameters can be changed
1 = Parameters locked. Vaisala recommends that you
set this parameter to 1 after you have configuration.
This prevents accidental changes, for instance, in RS-
485 use when there is interference.
<cr><lf>
=
Response terminator
NOTE
There are two SDI-12 modes available for providing 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. The data is outputted
on request. See
Chapter 8 Sensor and Data Message Settings, on page
.
