NMEA 0183 and NMEA 2000
The HM390S can be connected to both NMEA0183 and
NMEA2000 networks. When you connect your radio to
a NMEA 0183 network or a NMEA2000 network, the
following data can be transferred; the radio can receive
GPS position. GPS position can be displayed on the
screen and is transmitted with DSC calls. When GPS
data is not present, the radio will signal for you to enter
your position manually every four hours.When the GPS
data does not exist, the radio will signal you to manually
enter a position every four hours.
This setting indicates whether you are connected to a
NMEA 0183 or NMEA 2000 network; the radio can
communicate over two networks at the same time.
The interface used for NMEA0183 is RS232
Compass safe distance is 0.8m
