Page 5: Nmea Bridge Operation And Installation Handbook
Chapter 1: Introduction SeaTalk is the language used by all Autohelm products to share information. This is unique to Autohelm. The NMEA Bridge, by providing conversion between SeaTalk and NMEA 0183 data format, allows operation with other manufacturer's equipment . -
Page 6: Chapter 2: Mounting
• accessible for cabling • reasonably well protected from physical damage. Once a suitable location has been found, thoroughly clean the surface with an alcohol based cleaner. Remove the protective backing from the NMEA Bridge and firmly press onto the mounting surface. - Page 7 NMEA Bridge Operation and Installation Handbook Alternatively, the NMEA Bridge may be attached using the 2 self tapping screws provided. Remove the top of the Bridge by squeezing the lid at each end and pull away from the base. Route all the necessary cables into the Bridge.

Page 11: Nmea Input
NMEA Bridge Operation and Installation Handbook 3.2 NMEA Input The NMEA Bridge can also be used to convert NMEA 0183 data to SeaTalk. NMEA 0183 data is also re-transmitted on NMEA "OUT" in response to NMEA "IN". This allows non-SeaTalk equipment to be connected directly to the SeaTalk bus. - Page 12 NMEA Bridge Operation and Installation Handbook Data GPS Number of Satellites GPS Antenna Height GPS Quality Indicator Heading (Magnetic or True) Latitude & Longitude MOB (Cancel) Route Speed Over Ground Speed Through water Temperature, Water Time True Wind Angle Variation RMA, HVD Waypoint Destination No.
