Orion LT Sensor Data Output Definition
Wind data is transmitted every second. A Supervisory message is transmitted every 60 seconds when
heating is turned off and every 15 seconds when heating is turned on.
The RS-232 interface is as follows:
Bits per Second (baud rate): 9600
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
Note: The # sign after a parameter value indicates an invalid value.
Wind data
Example:
0r1,Dn=240D,Dm=249D,Dx=260D,Sn=4.3S,Sm=4.9S,Sx=5.4SMCO
where
0r1 = Wind message
Dn = Wind direction minimum (D = degrees)
Dm = Wind direction average (D = degrees)
Dx = Wind direction maximum (D = degrees)
Sn = Wind speed minimum (S = mph)
Sm = Wind speed average (S = mph)
Sx = Wind speed maximum (S = mph)
MCO = CRC-16 code
Supervisory Data:
Example:
0r5,Th=69.0F,Vh=0.0N,Vs=17.0V,Vr=3.483VCa~
where
0r5= Supervisory message
Th = Heating temperature (F = °F)
Vh = Heating voltage (N = heating is off)
Vs = Supply voltage (V = V)
Vr= 3.5 V reference voltage (V = V)
Ca~ = CRS-16 code
