Time window
For each output a time window can be specified during which it is able to
accept a trigger. The beginning of the time window is specified with the pa-
rameter
sta-time
and the end with the parameter
end-time
. If both pa-
rameters have the same value, the output is always active.
These settings can be used to ensure that the device will only be tripped at
certain times of day, for example only in the evening when photographing
bats.
If using these settings, it is important to ensure that the time of day on the
device is set accurately.

The parameter gives the possibility of linking two outputs. An output that is
linked to another is tripped at the same time as the other device.
An output cannot be linked to itself.
Inheritance is not intended to work. For example, if output c is linked to b
and output b is linked to a, output c will not trip if output a trips.
Application example: The parameter
link
of the output b is set to
with a
. The trigger for output a is set to light barrier 1 and that for
output b is set to light barrier 2.
Programmed in this way, output b trips when light barrier 2 is inter-
rupted due to its own trigger, but also when light barrier 2 is inter-
rupted because of the link to output a.
Practical example: The parameter can be used to set two different
time windows for documenting the activities of animals.
For example, the same trigger can be assigned to the outputs a and b
but each with a different time window (e.g., output a could be set
from 19:00:00 - 21:00:00 when bats might be leaving a cave in the
evening, while output b might be set from 05:00:00 to 07:00:00 when
they are returning in the morning). Output b is linked to output a.
Now, a camera connected to output b will be released in both time
windows.
