Setting Fields
[R] = Parameter selection: This field consists of 16 bits
defining the PTU parameters included in the data
messages. The bit value 0 disables and the bit value 1
enables the parameter.
The bits 1-8 determine the
parameters included in the
message obtained with the
following commands:
-ASCII: aR2 and ar2
-NMEA 0183: $--WIQ,XDR*hh
-SDI-12: aM2, aMC2, aC, and
aCC2
-SDI-12 continuous: aR2 and
aRC2 1st bit (most left) Pa Air pressure
2nd bit Ta Air temperature
3rd bit
Tp Internal temperature 1
1. Tp temperature value is used in pressure calculation, it does not express the air temperature.
4th bit Ua Air humidity
5th bit spare
6th bit spare
7th bit spare
8th bit spare
& delimiter
The bits 9-16 determine the
PTU parameters included in
the composite data message
obtained with the following
commands:
-ASCII: aR0 and ar0
-NMEA 0183: aR0, ar0
-SDI-12: aM, aMC, aC, and aCC
-SDI-12 continuous: aR and
aRC 9th bit Pa Air pressure
10th bit Ta Air temperature
11th bit Tp Internal temperature1
12th bit Ua Air humidity
13th bit spare
14th bit spare
15th bit spare
16th bit spare
[I] = Update interval: 1 ... 3600 seconds
[P] = Pressure unit: H = hPa, P = Pascal, B = bar, M =
mmHg, I = inHg
[T] = Temperature unit: C = Celsius, F = Fahrenheit
= Response terminator
