Raymarine Rudder Angle Transducer
The Rudder Reference transducer is compatible with the ST60+ instruments on the SeaTalk1 network. The transducer simply connects to the back of one of the ST60+ Rudder Angle Indicator instrument.
The Rudder Reference transducer is compatible with the i70, ST70 and ST70+ instruments on the SeaTalkNG network via an iTC-5 transducer converter (sold separately). The transducer is connected to the iTC-5 which converts the transducer signals to SeaTalkNG. The iTC-5 is then connected to your SeaTalkNG backbone.
Note that if your system contains an SPX autopilot the Rudder Reference should connect directly to the course computer and not the iTC-5.
