The NT920HDI converts serial heading data received from different types of proprietary heading |
transmission sources (electronic compasses including GPS antenna types etc.) to the data type required by |
various end user brands of radars, trackplotters and heading repeaters etc. including some Navitron auto- |
pilot types. In addition, NT920HDI software version 4.0 onwards incorporates speed log pulse input facilities |
which are combined with heading to provide NMEA output data (VHW sentence) for use by ECDIS etc. |
