used regardless of the settings of this parameter. When
the key has expired the R5 SUPREME W-AIS
Transponder will again use the channel determined by
this parameter.
Secure Channel Char.
This parameter is only used when “Link Type” is
set to “Secure”.
Determines which channel character should be used in
VDO/VDM messages for the third Secure channel. The
normal AIS 1 and AIS 2 channels have ‘A’ and ‘B’ as
channel characters.
The Secure channel has ‘C’ as
default but it can be change to any letter between ‘C’
and ‘Z’.
(BFT/STEDS) Encrypted
Reporting Rate
This parameter is only used
when “Link Type” is
set to “BFT” or “STEDS”.
Determines the reporting rate for encrypted messages
on AIS 1 and AIS 2 channels when in Tactical
(Protected) or Hybrid operational mode.
BFT/STEDS Alternative Mode
This parameter is only used
when “Link Type” is
set to “BFT” or “STEDS”.
When this parameter is set to “Enabled” the R5
SUPREME W-AIS transponder uses an alternative
implementation of BFT and STEDS transmissions to be
compatible with certain other manufacturers of W-AIS
transponders.
As default this parameter is set to
“Disabled” and in that
case the R5 SUPREME W-AIS transponder will be
backwards compatible with the R4SN and R4SWN
transponder systems.
3.2
Static Data Configuration
When the link settings have been configured (see section 3.1) it is important to configure
static data parameters for the encrypted link. This is done in the W-AIS
Static Data
view
which is accessed from
Main Menu
Configuration
W-AIS

.
The table
