The radiosonde also sends OIF ID data, which contains:
- Instrument type and number
- OIF serial number
- Diagnostics word
- Software version once per minute
OIF ID data replaces OIF measurement data, but not the additional sensor data, sent once per minute.
The OIF ID data contains the following information:
xdata= <Instrument type is
05><Instrument number is 01><OIF serial number><diagnostics word><SW
version><I>CR.
This means that if OIF sends
xdata=0501G12345670000000AICR
it is interpreted as shown in the following table:
Instrument type 2 bytes |
Instrument number 2 bytes |
OIF serial number 8 bytes |
Diagnostics word 4 bytes |
Software version 4 bytes |
ID data | |
---|---|---|---|---|---|---|
Hex ASCII | 05 | 01 | G1234567 | 0000 | 000A | I |
Interpreted as | 5 | 1 | G1234567 | 1 |
0xA=10 dec > SW version is 10/100= 0.10 |
Ignore Use data length to distinguish ozone and ID data. |
0000 = Default value, no diagnostics bits active
0004 = Ozone pump temperature below −5 °C.
0400 = Ozone pump battery voltage (+VBatt) is not connected to OIF.
0404 = Both “Ozone pump temperature below −5 °C” and “Ozone pump battery voltage (+VBatt) is not connected to OIF” are active at the same time.
