Also, if there are multiple meters attached it could contain multiple serial numbers separated by a comma for instance. Any
data that is useful could be stored here.
The 'Engineering' box contains parameters involved with the setup of onboard functions of the logger. The are several
communications monitoring parameters that are set to ensure that the communications to the logger are functional and
stable.
Battery operated loggers will wake up, connect to the server and upload their data. Should this fail, it would be a large
drain on the battery of the logger to continually try and connect. For this reason, the logger has a single chance to wake up
and establish a connection. If that fails, it will return to sleep and a only reconnect at the next wakeup period. At the start
of a wake up, the 'Max Start Time' timer will be started. Should the connection to the server take longer than this preset
time, the connection will be aborted and the logger will be put back to sleep. For powered loggers, the modem will be
powered down and the process to connect will be restarted from scratch until a connection is established.

connection and go back to sleep (battery) or re-establish a connection (powered).
