Configuring your AIS transceiver
Until correctly configured, your AIS class B transceiver will only
receive AIS messages and will not transmit AIS messages.
Switching on your AIS transceiver for the
first time
A few seconds after applying power to the AIS transceiver, the
indicators on the unit will illuminate in a pattern dependent on the
configuration state of the unit. The function of the four indicators
are:
Indicator Function
Green
Unit is powered up and operating normally
Amber Unit is in a 'transmit timeout' period
Red Unit has experienced an error
Blue Silent mode is activated
If the AIS transceiver has been pre-configured, the amber indicator
will illuminate until a transmission has been sent by the unit. This
may take several minutes, as the transceiver must acquire a GPS
position fix prior to transmitting its first message.
If the transceiver has not been pre-configured, the amber and red
indicators will be illuminated until the configuration process has
been completed.
