Example (SDI-12, device address 0):
0RU! 0RU,R=11111100&10000000,I=60,U=M,S=M,M=R,

Setting Fields
The parameter order is shown in the following table:
[R] = Parameter selection: This field consists of 16 bits
defining the precipitation parameters included in the
data messages. The bit value 0 disables and the bit
value 1 enables the parameter.
Bits 1-8 determine the
parameters included in the
messages obtained with the
following commands:
- ASCII: aR3 and ar3
- NMEA 0183: $--WIQ,XDR*hh
- SDI-12: aM3, aMC3, aC3,
aCC3
-
SDI-12 continuous: aR3 and
ar3
1st bit (most left) Rc Rain amount
2nd bit Rd Rain duration
3rd bit Ri Rain intensity
4th bit Hc Hail amount
5th bit Hd Hail duration
6th bit Hi Hail intensity
7th bit Rp Rain peak
8th bit Hp Hail peak
& delimiter
Bits 9-16 determine the
precipitation parameters
included in the composite
data messages obtained
with the following
commands:
- ASCII: aR0 and ar0
- NMEA 0183: aR0, ar0
- SDI-12: aM, aMC, aC, aCC
- SDI-12 continuous: aR and
aRC
9th bit Rc Rain amount
10th bit Rd Rain duration
11th bit Ri Rain intensity
12th bit Hc Hail amount
13th bit Hd Hail duration
14th bit Hi Hail intensity
15th bit Rp Rain peak
16th bit (most right) Hp Hail peak
[I] = Update interval: 1 ... 3600 seconds. This interval is
valid only if the
[M] field is = T
[U] = Precipitation units:
M = metric (accumulated rainfall in mm, Rain
duration in s, Rain intensity in mm/h)
I = imperial (the corresponding parameters in units
in, s, in/h)
