Vaisala WXT530 Series - Start Concurrent Measurement with CRC (aCC); Send Data Command (aD)

Goe
Correct three-character CRC for the ar1 command
IU~
T
hree-character CRC for the response message
<cr><lf>
Response terminator
Example of the other data query commands with CRC (when the device address is 0):

Precipitation query 0r3Kid<cr><lf>
Supervisor query 0r5Kcd<cr><lf>
Combined message query 0rBVT<cr><lf>
Composite data message

7.2.11 Automatic Mode
When the automatic ASCII protocol is selected, the transmitter sends data messages at
user-configurable
update intervals.
T
he message structure is the same as with data query commands aR1, aR2,aR3 , and aR5.
You can choose an individual update interval for each sensor.
Example:
0R1,Dm=027D,Sm=0.1M<cr><lf>
0R2,Ta=74.6F,Ua=14.7P,Pa=1012.9H<cr><lf>
0R3,Rc=0.10M,Rd=2380s,Ri=0.0M,Hc=0.0M,Hd=0s,Hi=0.0M<cr><lf>
0R5,Th=76.1F,Vh=11.5N,Vs=11.5V,Vr=3.510V<cr><lf>
