DATA Ports (NMEA0183)

2.3.1. Overview

Every MFD8/12 and MFDBB has THREE full NMEA0183 I/O Data Ports. One is
available on the DATA1 (7-Pin Connector) and is pin compatible with Navnet 1/vx2
DATA1 Connector. Two additional NMEA Ports are available on the DATA2 (18-Pin
connector).
These NMEA connections can accept a baud rate of 4800 or 38.4K. Any instrument
(GPS, AIS, Smart Sensor, etc...) can be connected to any port.
Heading: Heading input to NavNet 3D will allow functions such as Radar Overlay and
course stabilization (North Up, Course Up, etc.) in Radar operating modes.
IMPORTANT: The NMEA0183 heading refresh rate needs to be 100ms (10 times per
second or faster) in order for the Radar ARPA function to work properly. If ARPA is not
used, the refresh rate of heading information can be 200ms (5 times per second) to
support radar overlay on the plotter. NavNet 3D MFDs WILL NOT ACCEPT NMEA
0183 heading information if the refresh rate is only updated at 1 or 2 times per
second!! NMEA0183 heading can be accepted on any NMEA port at a baud rate up to
38.4kbps. Note that changing the baud rate on any of the three NMEA0183 Data ports
will affect both the receive and transmit baud rate. In other words, data sent and
received, must use the same baud rate for each individual data port.
Please refer to the Appendix (p. 74) for installation example with the Furuno Pilot and
Magnetic Compass PG500R
Note: Heading data from a NMEA2000 source/sensor will always be at the correct
refresh speed for the DRS ARPA function

2.3.2. DATA 1 description

DATA1 uses a 7 Pin round plug. In many cases the DATA1 will be used to directly
connect a Furuno GPS GP320B (P/N BBWGPS).
Other NMEA0183 compatible devices (Compass, AIS, Sounder, Smart Sensor...) can
be connected by using a 7pin connector-to-pigtail cable (P/N 000-154-028).
