2.4 Special features
Some variants of this AIS Transceiver are WiFi and Bluetooth enabled,
allowing for AIS data to be streamed from the transceiver to a 3rd party
device or to the em-trak app “CONECT-AIS”.
WiFi and Bluetooth enabled transceivers also provide an in-built vessel data
logger which will continuously record its own GNSS position and can be
downloaded using proAIS2 or CONNECT-AIS.
In the United States of America, the MMSI and static data must
only be entered by a competent installer. The end user of the
equipment is not authorised to enter their own vessel data.
