Maretron Rudder Angle Adapter RAA100. This allows you to observe rudder angle anywhere on the vessel where there is an NMEA 2000 compatible display such as the Maretron DSM200. The RAA100 is compatible with both the American standard (240-33 ohm) and the European standard (10-180 ohm) resistive senders. In fact the RAA100 can be calibrated for any resistance between 0 and 300 ohms. You can also use the RAA100 with existing analog gauges so you don't have to give up your existing analog gauges to enjoy the advantages of digitally networked information.
