GPRS connection
EZ Logger Lite also supports GPRS Internet connection for rural area. The connection
is shown below.
Please be aware that, due to bandwidth limitation, the data transfer rate (in the range
of 15~50kbps) is much less than Ethernet cable, the response of the web could be
very slow depends on real network conditions. We do not suggest to use GPRS
network to transfer big data such as images.

Internet Connection with multiple floating IP
To access the data logger via Internet by floating IP, it is more complex than static IP.
Because in a floating IP environment, the IP address might change frequently. In this
case, you need to setup DDNS of data logger as stated in section 3.2.3 . The DDNS
server is tracking your IP address all the time. To access the data logger, you just
have to key in the name given by your DDNS service provider.
