The diagram above has a double T connector with two 120-ohm 

terminators — one at each end of the connector. It is easy to expand this 

network by removing a terminator from one end of the double T connector, 
then inserting a new T connector or extension cable between the double T 

connector and terminator (See the NMEA 200 network general 
information document that came with your unit for more information). 

To exchange NMEA 0183 data, this unit has two NMEA 0183 version 

2.0 communication ports. Serial Communications Port one (Com1) and 

Serial Communications Port two (Com2)  can  be  used  to  transmit  or 
receive NMEA format GPS data.  
The five wires for the Serial Communications Ports are combined with 

the Display Unit Power cable and NMEA 2000 Power cable to form the 
power/data cable (shown earlier). Com1 uses the yellow wire to transmit, 

the orange wire to receive and the shield wire for signal ground. Com2 
uses the blue wire to transmit, the green wire to receive and the shield 

wire for signal ground.
