Section 4. Setting up Datalogger Networks
For Example:
If:
RF Polling Interval = 5 minutes
RF Poll Offset = X
Computer Offset = 4 minutes 47 seconds
Computer Poll Interval = 0
LoggerNet will query the RF Base 12 times per hour at:
XX:04:47, XX:09:47, XX:14:47, XX:19:47, XX:24:47, XX:29:47,
XX:34:47, XX:39:47, XX:44:47, XX:49:47, XX:54:47, XX:59:47
If:
RF Polling Interval = 5 minutes
RF Poll Offset = X
Computer Offset = 4 minutes 47 seconds
Computer Poll Interval = 3
LoggerNet will query the RF Base 20 times per hour at:
XX:01:47, XX:04:47, XX:07:47, XX:10:47, XX:13:47, XX:16:47,
XX:19:47, XX:22:47, XX:25:47, XX:28:47, XX:31:47, XX:34:47,
XX:37:47, XX:40:47, XX:43:47, XX:46:47, XX:49:47, XX:52:47,
XX:55:47, XX:58:47
Neither the Computer Offset nor the Computer Poll Interval has
any effect on when, or how often, the RF Base polls the RF
Remotes for data. The polling of the RF Remotes is determined
solely by the settings of the RF Polling Interval and RF Poll
Offset. NOTE

Standard
Communications Enabled – Before communications can take place, all
devices in the chain must have the Communications Enabled box checked.
When this box is selected, communication to the RF modem is enabled.
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.
