to This is unique to Autohelm The NMEA Bridge byproviding conversion between SeaTalk and NMEA 0183 dataformat allows operation with other manufacturers equipment The NMEA Bridge provides Conversion of NMEA 0183 data formats to SeaTalk Conversion of SeaTalk to NMEA 0183 format Operation of the Autohelm Main Alarm when an alarm condition exists on the SeaTalk bus RS232 terminals to send NMEA data to a personal computer echoes NMEA out6 NMEA Bridge Operation and Installation 2 MountingSelect a suitable location that is away from direct contact with water clean and greasefree accessible for cabling reasonably well protected from physical damage1 Once a suitable location has been found thoroughly clean the surface with an alcohol based cleaner2 Remove the protective backing from the NMEA Bridge and firmly press onto the mounting surfaceNMEA Bridge Operation and Installation Handbook 7 D43423 Alternatively the NMEA Bridge may be attached using the 2 self tapping screws provided4 Remove the top of the Bridge by squeezing the lid at each end and pull away from the base5 Route all the necessary cables into the Bridge6 Connect the wires as described in section 3 Also secure cables close to the unit8 NMEA Bridge Operation and Installation 3 NMEA you have the appropriate SeaTalk thedata listed below is transmitted in NMEA 0183 format for usewith nonSeaTalk equipmentNote NMEA is also
