Setting Fields
a = Device address
XU = Device settings command in ASCII and NMEA 0183
XXU = Device settings command in SDI-12
[A] = Address: 0 (default) ... 9, A ... Z, a ... z
[M] = Communication protocol:
A = ASCII, automatic
a = ASCII, automatic with CRC
P = ASCII, polled
p = ASCII, polled, with CRC
N = NMEA 0183 v3.0, automatic
Q = NMEA 0183 v3.0, query (= polled)
S = SDI-12 v1.3
R = SDI-12 v1.3 continuous measurement
[T] = Test parameter (for testing use only)
[C] = Serial interface: 1 = SDI-12, 2 = RS-232, 3= RS-485,
4 = RS-422
[I] = Automatic repeat interval for Composite data
message:1 ... 3600 s, 0 = no automatic repeat
[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 WXT520. During the delay, the WXT520'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: WXT520 (read only)
[V] = Software version: for example, 1.00 (read only)
<cr><lf> = Response terminator
