◆ 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.
