NMEA 0183
The NMEA 0183 Data Interface Standard was developed by the National 
Marine Electronics Association of America. It is an international standard that 
enables equipment from many different manufacturers to be connected 
together and to share information.
The information is passed in “sentences”, each of which has a three-letter 
sentence identifier. When you check to see if one item will “talk” to another, 
make sure that the two items both use the same sentence identifiers. For 
example: VTG carries Course and Speed Over Ground data; GLL carries 
latitude and longitude; DBT carries water depth; MWV carries relative wind 
angle and wind speed data.
The NMEA 0183 standard carries similar information to SeaTalk. However, it 
has the important difference that one cable will only carry information in one 
direction. For this reason NMEA 0183 is generally used to connect a data 
receiver and a transmitter together: for example, a compass sensor 
transmitting heading to a radar, or a GPS sensor (or Chartplotter) transmitting 
position and navigation data to a radar.
NMEA Input Connection
The two NMEA/Power input connectors are normally used for non-SeaTalk 
Compass (heading) data or GPS. It can also be used for additional navigation 
data (if not provided via SeaTalk).
Connect the input(s) to the orange and yellow wires (Channel 1) and/or the 
green and blue wires (Channel 2). Refer to Power and NMEA Input 
Connection
 on page 8-15
 for further details.
For example, to connect a Raymarine Heading Sensor to the NMEA 
Channel 1 input, connect the cables and power supply using a suitable 
connector block, as shown in the diagram below. If installed, it may be 
convenient to connect the power to the SeaTalk auxiliary junction box 
described in the following section.
