4.12 NMEA 0183 connection
NMEA 0183 devices can be connected to New c Series and New
e Series multifunction displays using the power and data cable.
Note: New a Series does not support connection of NMEA
0183 devices.

NMEA DEVICE
4800 / 38400 baud
NMEA DEVICE
4800 / 38400 baud
NMEA 0183 devices are connected using the supplied power
and data cable.
The display has 2 NMEA 0183 ports:
• Port 1 : Input and output, 4800 or 38400 baud rate.
• Port 2 : Input only, 4800 or 38400 baud rate.
Note: The baud rate you want to use for each port input must
be specified in the System Settings menu ( Homescreen: >
Set-up > System Settings > NMEA Set-up > NMEA Input
Port
).
Note: For Port 1, both the input and output communicate at
the same baud rate. For example, if you have one NMEA
0183 device connected to the display's Port 1 INPUT, and
another NMEA 0183 device connected to the display's Port
1 OUTPUT, both NMEA devices must be using the same
baud rate.
You can connect up to 4 NMEA 0183 devices to the display's
NMEA 0183 OUTPUT (Port 1). You can connect a total of 2
NMEA 0183 devices to the display's NMEA 0183 INPUT ports.
