5.10 GSM Settings
5.10.1 GPRS
‘GPRS’ defines main parameters for DB3 Plug&Play: GSM operator APN and
GPRS username and password (optional – depending on operator), destination
server IP and port, and allows to set protocol used for data transfers – TCP or
UDP. DB3 Plug&Play additionally supports backup server. If the main server is
not responding, DB3 Plug&Play connects to the backup server and still sends
records for 5 min (MAX) or until the link is not closed (can be closed by
configurable Active link TMO parameter). Both servers have the same
configurable parameters.
Some operators use specific authentication for GPRS session – CHAP or PAP. If
any of these is used, APN should be entered as ‘chap:<APN>’ or ‘pap:<APN>’.
I.e. if the operator is using APN ‘internet’ with CHAP authentication, it should
be entered as ‘chap:internet’. Information about APN and authentication type
should be provided by your GSM operator.
