ECDIS900 and can be entered either in AIS device either in ECDIS900.
The AIS transponder sends regularly ship's static data to ECDIS900 and vice versa ECDIS900
may send ship's static data to the AIS device.
If the user decides to use in ECDIS900 the static data entered in the AIS transponder,
ECDIS900 should not send the static data to the AIS. Therefore, when setting up the
communication in Sensor Monitor tick off the flag "Send data to the transponder".
Two kinds of filters can be applied to the sensor data.
