3.14 Long range messages
If the Poseidon transceiver is connected to a long range communication system via the long range
communications port then long range interrogations may be received. These are requests for information from
a distant base station beyond normal AIS operation range.
The Poseidon transceiver can be configured to automatically respond to Long range (LR) interrogations, or you
can opt to respond to any interrogation manually. Automatic response is the default setting, see section 3.16
for details of the menu option used to change this setting. Note that in automatic mode all requested information
is returned if it is available.
When a Long range interrogation is received you will be alerted by a notification screen as shown in Figure 18
(when automatic response is enabled) or Figure 19 (when manual response is enabled).
In automatic response mode simply review and acknowledge the notification screen using the ‘Acknowledge’
function key to return to the previous operating screen. In manual response mode you should review the
request and select either the ‘Respond’ or ‘Decline’ function key as appropriate.
