Section 4. Setting up Datalogger Networks
Maximum Time On-Line This field is used to define a time limit for
maintaining a connection to the device. (This may be useful in avoiding costly
communication costs, in the event that a connection to a station is inadvertently
maintained for a long period of time.) Maximum Time On-Line applies to both
scheduled connections and manual connections. However, for manual
connections from the Connect Screen, it is always best to manually disconnect
rather than relying on LoggerNet to disconnect for you.
When the device is contacted on a schedule, communication with the device
will be terminated once this time limit is exceeded. A value of 0 in this field
indicates that there is no time limit on maintaining a connection to the device.
When the device is connected in the Connect Screen and the time limit
approaches, a dialog box is displayed warning the user that Max Time On-Line
is about to be exceeded. The dialog box has Reset Max Time and Dont Reset
buttons. If the Reset Max Time button is pressed, the Max Time On-Line
counter will be reset. If the Dont Reset button is pressed or if no button is
pressed, the connection will be terminated when Max Time On-Line is
reached.
The format for this field is 00 h(ours) 00 m(inutes) 00 s(econds).
If you are using LoggerNet Admin or LoggerNet Remote 4.0 and
using the Connect Screen to connect to a remote server that is
running an older version of LoggerNet, the behavior will be
different than described above. When connecting to a LoggerNet
3.4.1 server, you will be disconnected with no advanced warning
when Max Time On-Line is reached. A message will be displayed
indicating that Max Time On-Line has been reached. When
connecting to servers older than LoggerNet 3.4.1, the behavior
will be variable. Generally, you will be disconnected at some
point, but the timing of the disconnect will not be predictable.
Network AddressEnter the network address that is set up in the RF400
radio. A unique network address is required only if there is more than one
network of dataloggers within the communication range of the network you are
configuring; otherwise, the default of 0 can be used. All devices in a network
must have the same radio network address. Valid Radio Net Addresses are 0
through 63.
Radio Address This is the unique radio address for the RF400 remote. Valid
addresses are 0 through 65,535.
Advanced
Maximum Packet SizeData is transferred in chunkscalled packets. For
most devices the default value is 2048 byes. The value entered in this field can
be changed in 32 byte increments. If a communications link is marginal,
reducing the packet size may improve reliability.
