3.13 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 254 other ship symbols/IDs. (The 225th is own ship's AIS symbol.)
If the displayed targets exceed 251, then the warning is displayed at the lower right of the screen.
AIS target count number at the upper right of the screen changes to yellow.
If the displayed targets exceed 254, then the alarm is displayed at the lower right of the screen. AIS
target count number at upper right of the screen changes to red.
In that case, change [INPUT RNG] value and decease the displayed targets.
Refer to “
INPUT RNG: Input range
” (page3-21)
* If the displayed targets exceed 254, 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 screen is turned red, then it means that the
input sentence is incomplete. So, this function does not work.
If AIS is used in combination with [ASSISTANT DISP], then AIS is effective.
Refer to “
ASSISTANT DISP
” (page4-38)
Enable AIS function
There are two types of method. One is [ON/OFF] using menu. The other is [ON/OFF] of [AIS] at the
upper right of the screen.

The setting area is determined by radius centered from the reference point.
Refer to “
INPUT RNG: Input range
” (page3-21)
Caution, the number of AIS symbols can not exceed 254. If the number exceeds 254, it causes a
[Overflow] message on the screen and triggers an alarm sound, and the capability of AIS symbol
display is lost.
