If more than three rings are specified (first P63 parameter
6 > 50), the datalogger may time out before the modem
answers; communication will never be established! It is
possible in some conditions to allow more than three rings.
Consult a Campbell Scientific applications engineer about
optimizing modem negotiations before trying this and be
sure to try the set up locally before installing at a remote
location. CAUTION
