GPS Speed to Log Speed (VTG -> VHW)

If this option is enabled, the multiplexer will generate a VHW sentence (water speed and heading)

when a VTG sentence (course over ground and ground speed) is received. The VTG sentence is

generated by a GPS and the VHW sentence by a log. Often the paddlewheel of a log gets stuck

when fouled and this option offers a solution to substitute the log data with GPS data.

Reverse Heading (HDT)

This option allows you to reverse the true heading in a received HDT sentence. When an HDT

sentence is received, the multiplexer generates a new HDT sentence with 180° added to the

original heading. This can be used to provide two opposing navigation stations on ferries with a

heading from the same gyro. Use the default route or Sentence Filter to route each sentence to a

different NMEA output and only one to the host if needed.
