At the customer’s option, you can connect a
NMEA device to the TV-Hub, allowing the
antenna to use its GNSS position and heading
data to speed up satellite acquisition. The current
position and heading will also be displayed on
the Home page of the web interface.
Follow these steps to connect a NMEA device to
the TV-Hub, if desired.
NMEA 0183
a. Wire and connect the 2-position terminal
strip connector (supplied in the kit) as shown
in Figure 34.
b. Configure the NMEA device to transmit one
or more of the supported NMEA 0183
messages at 4800 baud (see Figure 35).
NMEA 2000
a. Connect the TV-Hub to the vessel‘s
NMEA 2000 CAN network backbone via a
“T” connector, as shown in Figure 34. Be sure
to use a standard drop cable: 5-wire
(4 cond shield) twisted pair with
micro-C connectors.
b. Configure the NMEA device to transmit one
or more of the supported NMEA 2000
messages (see Figure 36).
Later, you will select the NMEA source at the
TracVision Setup Wizard (see
“Setup Wizard” on
page 27 ).
