The following parameters are available for each port:
Parameter
Description
type
Sensor type. See list below.
samplerate
Seconds between each recorded sample.
For example 900 means that a data point is
recorded each 15 minutes.
options
A bit mask the specifies special handling.
Normally leave at 0. The following options
are possible:
1 = actuate relay 1 during excitation period
2 = actuate relay 2 during excitation period
4 = actuate relay 3 during excitation period
These options are OR-able together, so
options = 3 means that both relay 1 and 2
are actuated during excitation.
excitation time
Number of milliseconds to excite the port
before sampling. Excitation refers to
application of the 5V reference voltage. For
certain actuation sensor types (such as
latching DC valves), this value is the time
the DC voltage is applied to valve.
The types available are:
Type Description
0
Sensor type. See list below.
23
Air temperature. 1-wire bus interface.
Deprecated - RS200 only.
24
Soil temperature. 1-wire bus interface.
Deprecated - RS200 only.
25
Air temperature. NTC type analog interface.
26
Soil temperature. NTC type analog interface.
27
NTC type temp sensor used as the internal temperature sensor in
the RS210 unit, and reported by default on port 0.
30
Rain gauge. 0.01 inch per tip, tipping bucket type. Only allowed on
port 8 (constant excitation).
NOTE: only port 5 can handle Rain
Gauge type (since constant power is required)
31
Rain gauge. 1 mm per tip, tipping bucket type (constant excitation).
NOTE: only port 5 can handle Rain Gauge type (since constant
power is required)
35
Wind speed sensor. Digital square wave, 1.25 MPH / HZ type.
36
Wind speed sensor. Digital square wave, 2.25 MPH / HZ type. For
example Davis Instruments wind speed sensors.
40
Wind direction sensors. Linear analog voltage type. North is at
crossing point between 0 and maximum voltage. For example
