“Appendix D - Eth-
Communications Server
The Comms server software manages the communications status of a recorder
across a comms port connection. Data can be configured for logging to a database and
realtime data transferred direct through a client connection such as
TrendServer
applica-
tion software.
Recorders are added to the comms server via connections to communications ports.
When recorders are entered, they can be configured for logging data to a database.
When the data is logging, the recorder will appear in the database list. Databases can be
added using the Database server. Realtime data is setup through the comms server
showing client connections i.e. the
TrendServer
application software, and comms port
settings. Realtime logging can be done through the
TrendServer
software or through the
comms server. All data, logged or realtime, can be interfaced directly from the comms
server to the server application software (client connection). To access the
Comms Serv-
er
and
Realtime
, ensure the recorders required have been added into the comms server.
For more detailed information on the Comms Server refer to the
cations manual.

Realtime Data Buffer
The realtime data has a buffer of time which can be set by the user so a timed
amount of data is stored in the buffer. This buffer is from 10 minutes to 2 hours,
then the oldest data will disappear from the realtime graph.
Go to the
System
button down the left side of the main screen, and select the
realtime icon.
