8.2 Setting up call-back in Loggernet
Where the logger is programmed to call-back to a Loggernet server, perhaps
because it has a dynamic IP address, Loggernet needs to configured to
expect a call-back on a the chosen port. The same settings apply whether
using the loggers own TCP/IP stack or the modem stack.
8.2.1 Setting up call-back in Loggernet Version 3
Version 3.x versions of Loggernet require an IPPort be entered for each
logger and a separate call-back socket be allocated to each IPPort. For each
socket you will need to open a hole in your firewall(s) and possibly put an
entry in your router tables, if using one.
In versions of Loggernet 3.4 there is an extra setting in the set-up screen
called “TCP Listen only”. This should be set when using dynamic, private
IP addresses to prevent Loggernet trying to call-back out to the logger in
some circumstances, e.g. loss of a connection. This setting ensures
Loggernet returns to a state of waiting for another call-back as soon as
possible. The setup screen for Loggernet 3.4 is shown below.
