User Manual SUNBC-14:NE0206 36
3.3 Modem Connection
Please Note: The Sunny Boy Control can be equipped with the optional
NET Piggy-Back for e-mail transmission and remote access. The NET
Piggy-Back is equipped with an internal communication module for either
analog, ISDN, Ethernet or GSM (mobile) transmission.
SMA recommends the usage of the NET Piggy-Back as this avoids possi-
ble compatibility problems as well as it reduces cabling and installation
modems etc. Note: The NET Piggy-Back only supports e-mail transmission
of status reports instead of Fax reports.

and fax transmission (bottom)
To enable remote data acquisition using the Sunny Data Control software or fax
transmission from the Sunny Boy Control, an external modem to be connected to the
phone line is required. We recommend the “Microlink 56k Pro” model from Devolo.
Note that the modem must be compliant with fax class 2.0 in order to communicate
reliably with the Sunny Boy Control. The list of AT commands (section 10.4) and a list
of recommended modem manufacturers (section 11.3) are included in the appendix.
