• T2 — Number of seconds for the second delay period.
TOI transmission rates
TOIs can be transmitted as either a single ‘OneShot’ transmission or as a recurring transmission.
TOIs generated from Intel targets or DSC targets are automatically assigned as OneShot TOIs. TOIs
generated from AIS targets and Radar targets allow the sender to select the TOI rate when the TOI is
created. Recipients and senders can change the TOI rate at anytime.
The following TOI rates can be selected:
• OneShot (Single Transmission) — TOI message is transmitted only once.
• Slow Target (600 sec repeat) — TOI message is transmitted every 600 seconds.
• Medium Target (180 sec repeat) — TOI message is transmitted every 180 seconds.
• Fast Target (60 sec repeat) — TOI message is transmitted every 60 seconds.
• Aircraft Target (15 sec repeat) — TOI message is transmitted every 15 seconds.
Note:
• A vessel can only send 1 recurring TOI message at a time. If a second recurring TOI message is
sent out it will replace the first TOI message.
• A vessel can send out multiple OneShot TOI messages.
• A vessel can receive multiple OneShot and recurring TOI messages.
• TOI rates for Intel targets and DSC targets are always set as OneShot and cannot be changed.
TOI cancellation repeat
To ensure a TOI cancellation is received cancellations can be automatically repeated multiple times
at a specified interval.
The cancellation repeat options are accessed from the Responder menu tab: Homescreen >
Settings > Responder > Advanced settings > Configure > CANCEL/UPDATE MESSAGES . For
following options are available:
• Repeat — Determines the number of times the TOI cancellation is transmitted.
• Interval — Determines the time interval between sending cancellation repeats..
TOI position updates
TOI positions are updated as follows:
• AIS targets and Radar targets will receive regular position updates from the relevant device.
• Intel targets will maintain their initially reported heading and speed
• DSC targets remain static, unless position reports are received.
Accessing target options
Target specific options are available for targets that are currently being tracked. The target options
can be accessed from the target’s context menu and from the Pop-over options in the relevant target
list. The options available are dependent on the type of target.
To access a target’s context menu:
• Press and hold on the target onscreen, or
• Highlight the target onscreen using the Direction controls and press the OK button.
To access the target list Pop-over menu:
• Select the target in the relevant target list, or
