The order of the output parameters from the sensor can change. The correct order can be found by sending the Get
Dataxml command to the sensor. The configuration properties can be seen by sending a Get All command or a Get
Configxml command to the sensor.

Calculated as (Beam1 Speed + Beam 3 Speed)-(Beam2 Speed+ Beam4 Speed)
where the BeamX speeds are tilt compensated. The Cross Difference is
Float
calculated for each ping and averaged at the end of the interval. In a
homogeneous water flow this value is close to zero.
In broadband mode only, this gives an indication of the quality of the speed data
