R5
SUPREME Secure W-AIS System

Startup Mode
Determines which Operational Mode the R5 SUPREME
W-AIS Transponder should start in after a power cycle.
(SECURE)
Encrypted Reporting Rate
This parameter is only used when “Link Type” is
set to “Secure”.
The reporting rate that should be used for encrypted
position reports
on the third “Secure” channel. If set to
“No Reports” the R5 SUPREME will not send any
automatic encrypted position reports on the Secure
channel
. If set to “Autonomous” the R5 SUPREME will
automatically determine reporting rate depending on
navigational status, speed over ground and rate of turn.
NOTE:
The reporting rate can also be set by the
encryption key. The reporting rate set in the key has
priority over this parameter so when a key with a
reporting rate set becomes active that reporting rate will
be used regardless of the settings of this parameter.
When the key has expired the R5 SUPREME W-AIS
Transponder will again use the reporting rate
determined by this parameter.
Encrypted Pos. Reports in
Hybrid
In Hybrid operational mode the R5 SUPREME W-AIS
Transponder will send open information as a normal
Class A on AIS 1 and AIS 2 channels, as well as
sending and receiving encrypted messages on the
encrypted link.
This parameter determines if the R5 SUPREME W-AIS
should also send encrypted position reports in addition
to the normal Class A position reports when in Hybrid
mode.
NOTE:
If the bogus functions (fake position and/or fake
static and voyage data) are enabled, the R5 SUPREME
will always send encrypted position reports with the
true information.
Secure Channel
This parameter is only used when “Link Type” is
set
to “Secure”.
It determines the radio frequency for
the encrypted secure link.
Only valid channels within the radios tuning range are
valid. I.e. if a maritime channel is to be used, any
channel according to ITU-R M.1084-3 can be used.
However ITU-R M.1084-3 does not define all possible
channels in the frequency band 155.000 MHz to
163.000 MHz, therefore a 3000 channel range is
introduced. (3000 = 155.000, 3001 = 155.025, ... 3319
= 162.975, 3320 = 163.000)
NOTE:
The secure channel can also be set by the
encryption key. The secure channel set in the key has
priority over this parameter so when a key with a
secure channel set becomes active that channel will be
