Primary Call Retry Interval
This is the number of min
utes to wait between each Primary retry attempt. The range is from 1
to 255 minutes.
Secondary Call Retry Interval
After the
Primary Call Retry Count
has expired, or if it was set to 0 to begin with, the
Secondary
Call Retry Interval
defines the number
of hours between each additional attempt, up to 255
maximum. There is no limit to the number of times the
CNI2
will attempt a call at this rate.
Once a call is successful the retry strategy is cancelled.
If the secondary interval is specified as 0 t
hen no further attempts will be made to retry the call.
Try Alternate Destination
If the
CNI2
attempts a call
and the call is unsuccessful for any reason,
it can immediately retry
the call to a different destination. If this 2nd call also
fails then the
CNI2
will follow the normal
retry strategy described earlier. Each new retry will start with a call to the primary destination
followed by a call to the alternate destination if the call to the primary destination fails.
This feature is us
eful when there are several data collection systems sharing the same
database and the primary system is overwhelmed with other calls or is down for maintenance or
some other reason.
Even if the retry strategy is disabled, if the
Try Alternate Destination
is checked, the
CNI2
will
still try one call to the alternate destination if the call to the primary destination fails.
Enable Repetitive Call Schedule
In some applications you might want the
CNI2
to call in at regular intervals. Check the box and
ente
r the time period in
minutes
. This schedule will be followed as soon as the unit is reset or
reprogrammed.
For instance if the unit is to call in every 24 hours enter a value of 1440
minutes.
To
completely
disab
le the retry strategy, set
both
the
Primary Retry Count
and the
Secondary Retry Interval
to zero (0).
D
isabl
ing
the retry strategy
is
not
recommended for most applications. Each time the CNI2
contacts

it is given a new time to call back
. If a call fails and the unit
is not allowed to retry the call, it will never receive a new call
-
back time and therefore will
not have a reason to call back again unless an alarm situation forces a new call.
If you do disable the retry strategy you may
want to consider using the
Repetitive Call
Schedule
feature. With this enabled the unit will have another reason to call in at a later
time.
