Connect an NMEA Talker

Connect an NMEA Talker
The antenna requires a vessel heading input from a
customer-supplied NMEA 0183 or NMEA 2000 talker.
Optionally, you can also provide a vessel position input to
serve as a backup to the antenna's built-in GPS.
NMEA 0183
1. Connect the NMEA 0183 talker to the 2-position
terminal strip connector (supplied in kit), as shown in
Figure 22. Then plug the connector into the rear panel
of the VSAT-Hub.
2. Configure the NMEA device to transmit one or more of
the supported NMEA 0183 messages at 4800 baud.
3. Make sure the data message(s) includes the
checksum, identifiable by a *xx field at the end of the
data sentence (e.g., $HEHDT,123.4, T*1F). Do not
exceed a 10 Hz input rate.
Note: To supply both the required heading and the
optional position to the VSAT-Hub, you can either connect
an NMEA 0183 talker that transmits both messages, or
connect two devices using an NMEA data multiplexer, such
®
as Actisense model NDC-4.

NMEA 2000
1. Connect the VSAT-Hub to the vessel's NMEA 2000
CAN network backbone via a "T" connector. Be sure
to use a standard drop cable: 5-wire (4 conductors +
shield) twisted pair with micro-C connectors.
2. Configure the NMEA device to transmit one or more of
the supported NMEA 2000 messages.
