  1. How do I display the RAA100 rudder angle on Maretron’s DSM150, DSM200, or DSM250 display? You display the RAA100 rudder angle on a DSM150, DSM200, or DSM250 in the following way. Enter menu mode, scroll to "Favorite Screen Setup..." and press enter. Scroll to the favorite screen where you would like to view the rudder angle and press ente... Read More
  2. Why I can’t find a RAA100 rudder angle for display on Maretron’s DSM150, DSM200, or DSM250? In order to keep the number of Maretron DSM150, DSM200, and DSM250 display menu items to a minimum (there is a possibility of more than 250 batteries, more than 250 engines, more than 250 rudders, etc.), the displays default to only a single rudder. ...

  3. How do I set the RAA100 rudder number or instance using Maretron’s DSM150, DSM200, or DSM250 display? You set the RAA100 rudder number or instance using Maretron's DSM150, DSM200, or DSM250 display in the following way. Enter menu mode, scroll to "Configuration…" and press enter. Scroll to "Device Configuration…" and press enter. Scroll to the row co... Read More
  4. What type of rudder senders does the RAA100 work with? The RAA100 works with resistive rudder angle senders (i.e., the resistance changes with rudder angle). In the U.S., the standard for resistive senders is 240 to 30 ohms where 240 ohms represents 60 degrees to port and 30 ohms represents 60 degrees to... Read More
  5. I know that the RAA100 uses resistive rudder angle sensors; who manufactures resistive sensors? The RAA100 is compatible with resistive rudder style sending unit. The brand, VDO manufacturers a sensor (Figure#1) that can output 10-180Ω of resistance range. Simply connect the RAA100's white and black wires to the VDO sender's positive(... Read More
  6. Why doesn’t my rudder display read hard over when the rudder is hard over? The rudder display may not read hard over even though the rudder is hard over if the resistive sensor is not turning throughout its entire range. You can fix this by either adjusting the resistive sensor to turn across its entire range or you can per... Read More
  7. What is an RAA100? The RAA100 is a rudder angle adapter that converts an analog resistive sender into digital information, which is then broadcast over the NMEA 2000 where any NMEA 2000 compatible display can show the rudder angle. The RAA100 can be used with or withou... Read More
  8. What information does the RAA100 provide? The RAA100 provides the the rudder angle.... Read More
  9. What messages (or PGNs) does the RAA100 transmit? The RAA100 transmits the following message (or PGN):PGN 127245 - Rudder (Fields: 5 - Position)... Read More
  10. Can I set the RAA100 to accept the European standard for resistance values (i.e. 10 to 180 ohms) using Maretron’s DSM150, DSM200, or DSM250 display? Yes, it is possible to set the RAA100 to accept European standard resistive sensors using Maretron's DSM150, DSM200, or DSM250 display. Set the mode using Maretron's DSM150, DSM200, or DSM250 display in the following way. Enter menu mode, scroll to "... Read More
