By setting the Change to Null connector after last call other than 0 will
change the active connector to the Null connector after the last received call
(minimum timeout value is 5 minutes). For example, if you set a timeout of 600
seconds, openSPOT4 will change to the Null connector if there is no call
received in the last 10 minutes.
If Power down instead of changing to Null connector is checked, then the
device turns off when the timeout is reached. This can be used as an auto sleep
feature.
