The radiosonde also sends OIF411 ID data, which contains:
- Instrument type and number
- OIF411 serial number
- Diagnostics word
- Software version once per minute
OIF411 ID data replaces OIF411 measurement data, but not the additional sensor data, sent once per minute.
The OIF411 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 OIF411 sends
xdata=0501G12345670000000AICR
it is interpreted as shown in Table 1:
|
Instrument Type 2 Bytes |
Instrument Number 2 Bytes |
OIF411 Serial Number 8 Bytes |
Diagnostics Word 4 Bytes |
Software Version 2 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 OIF411.
0404 = Both “Ozone pump temperature below −5 ºC” and “Ozone pump battery voltage (+VBatt) is not connected to OIF411” are active at the same time.
