In addition, NT925HDI units incorporating software version 2.0r and later, will accept 200 or 400 pulses per nautical mile from speed log systems and will provide NMEA output data in heading only, speed only or combined speed and heading formats as required by ECDIS and AIS Systems etc. Version 3.0 software and later also provides Rate of Turn (ROT) NMEA data outputs.
