Notes:
1. A RayData unit set up as a Master for depth data will take data from
its direct-connected transducer or (if there is no direct-connected
transducer) NMEA, and ignore the indicated SeaTalk data.
2. A RayData unit set up as a Master for speed and temperature data
will take data from its direct-connected transducer or (if there is no
direct-connected transducer) NMEA, and ignore the indicated
SeaTalk data.
3. TDs Position is only available via an NMEA connection.
