The structure of the supervisor response message:
M =
Transducer id 1 units (hits/cm
2
, Hail peak intensity)
3 = Transducer id for Hail peak intensity
* Checksum delimiter
51 = Two-character checksum for the response
<cr><lf> = Response terminator
where
$
= Start of the message
WI = Device type (WI = weather instrument)
XDR = Transducer measurement response identifier
C = Transducer id 2 type (temperature), see the following
Transducer table
20.4 = Transducer id 2 data (Heating temperature)
C = Transducer id 2 units (C, Heating temperature)
2 = Transducer id for Heating temperature
U = Transducer id 0 type (voltage)
12.0 = Transducer id 0 data (Heating voltage)
M = Transducer id 0 units (N = heating disabled or
heating temperature too high
1
, Heating voltage)
0 = Transducer id for Heating voltage
U = Transducer id 1 type (Supply voltage)
12.5 = Transducer id 1 data (Supply voltage)
V = Transducer id 1 units (V, Supply voltage)
1 = Transducer id for Supply voltage
U = Transducer id 2 type (voltage)
3.460 = Transducer id 2 data (3.5V reference voltage)
V = Transducer id 2 units (V, 3.5V reference voltage)
2 = Transducer id for 3.5V reference voltage
G = Transducer id 4 type (generic)
HEL/___ = Transducer id 4 data (info field)
Transducer id 4 units (none, null)
