Primary Call Retry Interval

This is the number of minutes 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 then no further attempts will be made to retry the call.
To completely disable the retry strategy, set both the Primary Retry Count and the
Secondary Retry Interval to zero (0).
Disabling the retry strategy is not recommended for most applications. Each time the CNI2
® ®
contacts DC-2009 or MV90 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.

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 useful 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
enter 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.
