33NMEA 0183 ConnectionsThe Autopilot does not need to connect to a GPS for the autopilot to work, but if you want to usewaypoint steering you must connect to a GPS and set North see page 30. The Autopilot will acceptNMEA input from two GPS units and transmit NMEA to one receiving device. Only one of the GPSinputs is used for steering control at a time. Selection of the controlling GPS is made through theNMEA source selection [code 34] (see pages 19-22 for explanation of setup codes). The NMEAoutput port transmits the NMEA sentence $APHDG at 4800 baud. The output refresh rate is selectablevia [code 49] from 0 to 10 Hz. The Autopilot requires the data sentences RMC and RMB to be on.The NMEA conductors are in the cable stub at the base of the Compass Ball. (See Labels on Wiresfor Identifi cation) The wire color codes and signal names are shown in the wiring diagram below.You must calibrate the compass ball and set North during Sea Trial of autopilot for it to workcorrectly.Note: If you are using Radar Overlay, you may need to adjust code 168 in order for your overlay toline up correctly.See pages 38-41 in the installation manual or go to www.tr-1autopilots.com (Manuals)for updatesof specifi c brands of GPS wiring confi gurations.
