5.1.1 STEDS operating modes
When STEDS operation is enabled the AIS Transceiver may operate in the
following modes:
● Receive Only
● Normal Transmit
● Restricted Transmit
In
Receive-Only
, all broadcast and own-vessel addressed AIS messages
received over the standard AIS VDL channels shall be reported via the
presentation interface. The AIS shall not transmit any AIS messages either
autonomously or by interrogation. In addition, channel management via DSC
or AIS VDL shall not be applied.
In
Normal Transmit
the AIS shall operate as a AIS Class A transceiver,
transmitting standard AIS Class A position and static data reports in the
normal manner defined by the relevant AIS standards. In addition, EAIS
application specific messages presented to the AIS at the presentation
interface as defined in Table 1 may be transmitted.
In
Restricted Transmit
only EAIS application specific messages (ASM)
presented to the AIS at the presentation interface as defined in Table 1 may
be transmitted.
The current STEDS operating mode of the AIS is indicated on the MKD.
