This means that if OIF411 sends
xdata=050108CA186A0750B637CR
it is interpreted as shown in Table 15 on page 100 :
ID Data
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=0501G12345670001000AICR
