Connecting directly to NMEA equipped instruments
Most instrument systems are equipped to accept incoming NMEA data from your GPS,
and will output additional collected NMEA data, such as position, heading, speed,
water depth etc.
To connect directly to an NMEA equipped instrument system:
Connect the cables as follows:
Cable color
Yellow (Rx)
Black (SGnd)
Green (Tx)

Connecting directly to radar
In order for RNS to be able to display variable range markers (VRM's), electronic
bearing lines (EBL's) and cursor information, the radar system you use must be able to
output the NMEA RSD string.
To display MARPA targets, your radar system must be able to output NMEA TLL or TTM
strings. If you are using this feature, make sure your radar system is correctly tracking
MARPA targets before connecting it to RNS.
To connect RNS directly to a radar system:
:
Connect the cables as follows:
Cable color
Yellow (Rx)
Black (SGnd)
Green (Tx)
