Example of the response (you can select the parameters included
from the full parameter set of the commands aR1, aR2, aR3, and
aR5):
0R0,Dx=005D,Sx=2.8M,Ta=23.0C,Ua=30.0P,Pa=1028.2H,
Rc=0.00M,Rd=10s,Th=23.6C<cr><lf>
For information on selecting the parameter set in the response message,
see Chapter 8 Sensor and Data Message Settings, on page 127.
Polling with CRC
Use the same data query commands as in the previous sections but type
the first letter of the command in lower case and add a correct three-
character CRC before the command terminator. The response also
contains a CRC. For more information on CRC computation, see
Appendix C CRC-16 Computation, on page 199.
Requesting a wind data message with a CRC:
Command format: ar1xxx<cr><lf>
Example of the response (the parameter set is configurable):
0r1,Dn=236D,Dm=283D,Dx=031D,Sn=0.0M,Sm=1.0M,Sx=2.2MLFj
<cr><lf>
where the three characters before <cr><lf> are the CRC for the
response.
where
a = Device address
r1 = Wind message query command
xxx = Three-character CRC for ar1 command
<cr><lf> = Command terminator
NOTE
To request the correct CRC for each command by typing the command
with an arbitrary three-character CRC.
