Vaisala WXT530 Series User Manual

Parameter Description
[B]
Baud rate: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200
[D]
Data bits: 7/8
[P]
Parity:
O = Odd
E = Even
N = None
[S]
Stop bits: 1/2
[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. Eective in ASCII, polled and NMEA 0183 query protocols. Eective
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
in
terference.

Response terminator
There are two SDI-12 modes available for providing the functionality of the SDI-12 v1.3
standar
d.
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.
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>
