Application tips
Reboot Hold Time
Besides the classic reset of the monitored device and its following release IP WatchDog2 still a
possibility of permanent Reset state in case the monitored device does not respond to the demands
of IP WatchDog2 or does not send periodically refresh impulses. This mode is activated by setting
the parameter
Reboot Hold Time
to 0. If in this case state is performed RESET, the channel (or its
output) in this state until the monitored device reports itself again, or if no channel is deactivated.
The function is designed for cases where IP WatchDog2 does not reset directly monitored device or
when one of the channels used to activate the backup device or other alarm system.
Note:
If the value Reboot Hold Time = 0, the IP WatchDog2 in a special mode Reset function and
especially Manual Reset behave somewhat differently than described on the previous pages,
because the Reset state can not be ended by itself. This is especially true when using Manual
Reset button with deactivated channel when there is no standard way how to reverse Reset state
and the only way is to activate the channel and initialize the refresh impulse.
