modem (path, login …)
.
•
Check the ftp and directories configuration:

•
Does the radar measure?
o
Are the radar and modem properly powered?
o
Connect to the radar and check if the measurements are ok.
o
Check param 50 (must be set on 121 to be readable by the modem, on 8 to be human readable).
o
Check other radar parameters.
There is no RS-232 communication between the PC and the radar
•
Check the wiring and the connectors.
•
Check
the terminal emulator software configuration (baud rate, com port number …)
.
The timestamp is faulty
