The application allows for simultaneous communications with the receiver and an echosounder system that provides information for bathymetry work.

The communication parameters with the echo sounder, as well as the Height value should be set through this option

The Enable check box should be marked to establish communications once all the parameters have been configured and the application has been reinitiated.

The altitude is calculated as follow:

 (GPSAltitude – GPSAntennaHeight) – (EchosounderDeep + EchosounderHeight)
