Example of the other data query commands with CRC (when the
device address is 0):
In every case the response contains a three-character CRC before the
<cr><lf>.
For selecting the parameters to be included in the response messages,
changing the units and making other configurations of the measured
parameters, see
Chapter 8, Sensor and Data Message Settings, on page

is same as with data query commands aR1 and aR5. You can choose an
individual update interval for each sensor, see
Chapter 8, Sensor and
Data Message Settings, on page 95 , sections Changing the Settings.
Example:
0R1,Dm=027D,Sm=0.1M<cr><lf>
0R5,Th=76.1F,Vh=11.5N,Vs=11.5V,Vr=3.510V<cr><lf>
where
a
= Device address
tX,Use
chksum = Text prompt
Goe = Correct three-character CRC for the ar1 command
IU~ = Three-character CRC for the response message
<cr><lf> = Response terminator
Supervisor query = 0r5Kcd<cr><lf>
Combined message query = 0rBVT<cr><lf>
Composite data message query = 0r0Kld<cr><lf>
