Appendix F: Demonstration mode
The RX-C4 is equipped with a demonstration mode. With this demonstration mode the
customer is able to test the connection between their RX-C4 receiver and presentation software
Waves21 and/or Waves4 without having a Waverider buoy available. Moreover, customers will
be able to get familiar with the capabilities of the software packages.
The RX-C4 will output heave, north and west displacements as well as a heave and directional
spectrum which are programmed in the firmware. The displacements and spectrum have the
following characteristics and are easily distinguished from ‘real’ wave data:
