Stealth
It’s possible to leave GPS and/or GSM powered on even when the Force One has been switched off.
Leaving GPS on can be useful to have an immediate position fix at start-up, otherwise some time,
usually less than one minute, can be required for a cold fix.
Leaving the GSM on is used to remotely wake-up the Force One. This can be achieved by calling from
the central, using the voice or data number. When the AITP detects the first RING coming from the
GSM, it can wake-up the Force One.
In this case it is also possible to start the system in Stealth Mode, that means with an hidden user
interface, for example for alarm monitoring. User applications can read Stealth status from the
AITP
and behave consequently.
Digital I/O
It is used to monitor the actual status of Digital I/O.
Digital I/O status can be read either with a polling request to the
AITP
, or activating the I/O trigger on
the desired input and front. In this case the AITP spontaneously send a message to the application
when the required change is detected on the Special Input.
