4.2 AIS

The AIS communicates with other ships via VHF (Very High Frequency) radio by transmitting your
ship information and by receiving other ships information.

Only AIS data with WGS84 datum is accepted.
If AIS data has no datum or if datum is other than WGS84, then the warning of [AIS datum is not
WGS84] appears. AIS data is not displayed.

Capable of displaying up to 1000 other ship symbols/IDs.

If the displayed targets exceed 951, then caution is displayed at the lower right of the display. AIS
target count number at the upper right of the display changes to yellow.

If the displayed targets exceed 900, then warning is displayed at the lower right of the display. AIS
target count number at upper right of the display changes to red.
In that case, change [TARGET] => [INPUT RNG] value and decrease the displayed targets.
Note:
• If the displayed targets exceed 1000, then next coming AIS data cannot be displayed. For the sake of
safety, if warning is displayed, then change [INPUT RNG] value immediately and decrease the
displayed targets.
• If the own ship information display at upper right of the display is turned orange, then it means that the
input sentence is incomplete. So, this function does not work.
If AIS is used in combination with [ASSISTANT INFO DISP], then AIS is effective.
