When Radiosonde RS41 is connected to Ozone Interface Board OIF411, it sends the OIF411 measurement data through the additional sensor interface. The following information is contained:
- Instrument type and number
- Ozone pump temperature
- Ozone current
- Battery voltage
- Ozone pump current
- External voltage measured once per second
OIF411 measurement data contains the following information:
xdata= <Instrument type is
05><Instrument number is 01><Ozone pump T [0.01 ºC]><Ozone current
[0.0001uA]><Battery voltage [0.1V]> <Ozone pump current [1 mA]><Ext.
voltage [0.1V]>CR
This means that if OIF411 sends
xdata=050108CA186A0750B637CR
it is interpreted as shown in Table 1:
|
Instrument Type 2 Bytes |
Instrument Number 2 Bytes |
Ozone Pump T [0.01 ºC] 4 Bytes. MSB bit is a sign bit. |
Ozone Current [0.0001uA] 5 Bytes |
Battery Voltage [0.1V] 2 Bytes |
Ozone Pump Current [1 mA] 3 Bytes |
Ext. Voltage [0.1 V] 2 Bytes |
