The AIS transponder communicates with the ECDIS via a serial cable (NMEA 422 protocol).
The duplex link between the AIS and ECDIS allows two-way communication:
• The ECDIS receives dynamic data (targets’ positions and information) and
messages
from
AIS.
• The ECDIS transfers own ship’s static and voyage data to the AIS.
• The ECDIS may also be used to send
messages
to selected recipients.
IMPORTANT
Ship’s static data including Ship’s name, length, etc….are used in both AIS transponder and
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.
AIS Sensor can be switched to the Native Heading mode but the AIS heading could be
unreliable or not precise enough. So the proper warning appears if the “Use heading as
