About Monitoring Communication Time
Please note that if the monitoring interval is set for less time than
communication takes to complete a round of monitoring, the system will
automatically extend the interval to allow for the necessary amount of
communication time. A short interval between monitoring sessions will result in
a shortened battery life.
The following is a rough estimate of communication time; this will, of course,
depend on the number of groups and remote units registered to the collector.
Note
・
After communication has completed, display time will take about
2
seconds per unit
<Communication Time for [All Groups] >
・
If there are
64
Remote Units registered to the group
（
24
seconds per group x Number of groups
）
・
If there are
120
Remote Units registered to the group
（
54
seconds per group x Number of groups
）
Moreover, the display time for each unit is about
2
seconds.
<Communication Time for [Specify Groups]>
The communication time will depend on the number of registered remote
units. For
250
units registered to
1
group the time will be
54
seconds plus a
display time for each unit of
2
seconds.
