devices.
Connecting RNS to your instruments
The connection between the PC that is running RNS and your instruments is achieved
using a 9-pin cable, Raymarine Part No. E86001. One end connects directly to your PC’s
Serial Port, the other to the various devices.
Connecting directly to a GPS
Connecting RNS to a Global Positioning System (GPS) is the simplest way to get
position data.
To connect RNS directly to a GPS:
1. Verify that GPS NMEA output is turned ON.
2. Set the GPS datum to WGS84.
3. Using Raymarine Cable Part No.E86001, connect the cables as follows:
Cable color GPS lead
Yellow (Rx) NMEA + output
may also be labelled Tx, Tx+, Data out +, or NMEA OUT +.
Black (SGnd) Not used
Green (Tx) Not used
Black (SGnd) NMEA - output
may also be labelled TX-, Data out-, NMEA- out, or Ground
.
