aM!
a0001<CR><
LF>
Request the device with address number "a" to execute measurement.
0001: indicates the 3-digit measurement execution time (000 indicates
instantaneous), and the 4th digit indicates the number of data to be
returned (1 piece).
aD0!
aD1!
aD2!
aD3!
a+1000.0<CR
><LF>
Request to send data to the device with address number "a".
The output value is always appended with a sign (+ or -).
If there is more than one output, the sign is also the delimiter.
D0: Irradiance (W/m
2
) 1 digit after decimal point
D1: Sensor output voltage (mV) 4 digits after decimal point and Sensor
temperature (Celsius) 2 digits after decimal point
D2: X-axis tilt angle (degree) 1 digit after decimal point, forward/backward
with connector facing back, positive value when back is up, Y-axis tilt
angle (degree) 1 digit after decimal point, left/right with connector
facing back, negative value when left is down
D3: Temperature inside enclosure (°C) 1 digit after the decimal point,
Humidity inside the enclosure (RH %) 1 digit after the decimal point.
If the pre-measurement command is “MC”, then three CRC characters are
followed, please refer to SDI-12 standard for the content of CRC
characters.
aMC!
a0011<CR><
LF>
Request the device with address number "a" to start measurement and
request the CRC to confirm that the command is correctly accepted. The
response format is the same as “aM!”
aC! a00101<CR>
<LF>
This device is the same as the “aM!”
command except for the difference in
the number of response characters.
The character following a indicates the number of seconds (3 digits) and
the number of data (2 digits).
aCC!
a00101<CR>
<LF>
This transmitter is the same as the “aMC!” command except for the
difference in the number of response characters.
aR0!
a+0.0<CR><L
F>
Request a measurement from the device with address number "a".
Measurement is executed and a response is returned immediately. The
answer is similar to “aD0!” to” aD2!” command.
aRC0!
a+0.0EmT<C
R><LF>
Request measurement from the device with address number "a" and
request
error detection to verify that the command was accepted correctly.
Measurement is executed and the measured value with three CRC
characters added at the end is returned instantly.
aXSE!
a+XX.XX<CR
><LF>
Read the sensitivity constant of this device. Two digits after the decimal
point.
aXCD!
aYYYYMMDD
<CR><LF>
Read the calibration date of this device. YYYY: AD, MM: month, DD: day.
