■ AIS data
When radar images cannot be recorded, the output data of AIS must be recorded as an alternative.
However, JCY-1800/1850 can also record both all AIS data and radar images.
■ Setup by Maintenance soft ware for recording the AIS data
Only by changing the following setup, the data outputted from AIS is recordable by the same setup as
other NMEA sentences.
• Baud rate : 38400
