3.6.3 GPRS connection without VPN tunnel
A GPRS connection without a VPN tunnel is only possible if a CDA account has been set
up with a mobile network operator. If this is the case, only the software settings need to
be configured on the sc1000 controller (
); configuration of the
VPN itself is part of CDA administration.
Without a CDA account, it is only possible to connect to the Internet. E-mails can be sent,
but access to the sc1000 controller is not possible with this type of connection.
