3.11 Message Handling
Message Handling works as for a normal Class A when in
Normal
Operational Mode. It is
also possible to send encrypted SRM or text messages when working in
Tactical
and
Hybrid
Operational Mode and BFT Link or Secure Link is used. It is currently
NOT
possible to send encrypted SRM and text messages when using STEDS Link.
To send an encrypted SRM or text message, the system must be in the
Tactical
or
Hybrid
Operational Mode
and the link type must be set to “Secure ” or “BFT”, see section 3.1. A
valid key must also have been entered as described in section 3.5.
When using BFT link type, all SRM and text messages will be encrypted in both
Tactical
and
Hybrid
mode. When the Secure link type is used, the messages will be encrypted if
the c
hannel is set to “Secure”.
Sending an SRM or text message over the encrypted link is done in the same manner as
sending a message in a normal R5 SUPREME Class A Transponder System. The
AIS
Message Send
view is accessed from
Main Menu
Messages
AIS Messages
Send
.
Choose between addressed or broadcast SRM or text message, select destination and
enter text as described in your R5 SUPREME AIS Transponder System Manual, in
section “Handling Safety Related Messages (SRM) and Text Messages”.
Note: It is not possible to send SRMs when in the Silent or External Operational Mode.
