Group Settings
Mobile units can be assigned to 5 different polling groups (A, B, C, D or E). These groups,
when selected for polling, automatically select the appropriate mobiles from the polling list and
tracking commences at the ‘auto start’ time. When the current time is the same as the ‘auto
stop’ time then polling stops and mobiles from that group are deselected from the polling list.
Interval -
the time in seconds/minutes or hours between position update requests of
mobiles in a particular group. If this option is set to 0, polling will be done
continuously.
Auto Start -
The time at which the system will automatically start polling all vehicles in the
appropriate polling group.
Auto Stop -
The time when automatic polling is to be stopped.
Poll Times
Select poll times from within polling groups window.
Group polling can also be set up in such a way that polling of all mobiles belonging to a particular
group will take place at specified times. Five poling times can be defined for each polling group.
The system will poll and display positions of all mobile units belonging to a group only once when
the polling time occurs. For example group A (mobiles 1, 2 and 3) has one poll time defined
(09:45:00am), which means that mobiles 1, 2 and 3 will display only once at 09:45:00am.
