Nmea 0183 Connection - Lighthouse a65 Installation And Operation Instructions Manual

4.21 NMEA 0183 connection

NMEA 0183 devices can be connected to compatible
multifunction displays (MFDs) using the power and
data cable.
Note: To connect an NMEA 0183 device to an a6x
or a7x MFD a SeaTalk
must be used to convert the SeaTalk
to NMEA 0183 messages.

NMEA DEVICE
4800 / 38400 baud
NMEA 0183 devices are connected using the power
and data cable supplied with compatible MFDs.
2 NMEA 0183 ports are available:
• 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.
