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>
