6. SBES: EchoLogger#

Note

The Sensor may be connected/disconnected only when the system is powered off.

  • Attach the Universal Heavy Payload mount to the bottom of your drone.

  • Attach the Echologger to the Universal Heavy Payload mount.

  • Connect the cable to the SkyHub Connector #4 (white).

Power on the system.

  • Establish either the drone link or auxiliary connection with the SkyHub in the UgCS-CPM software.

  • On the main screen of the UgCS-CPM, click on the “Payloads” button.

  • From the available payload list, enable the “SBES: EchoLogger”.

  • Press the “Save” button and confirm system reload.

Wait until the reload process is finished and the connection to the SkyHub is reestablished.

  • On the main screen of the UgCS-CPM, click the “Start” button.

  • From the drop-down widget list, select the “SBES: EchoLogger single-frequency” if you have the ECT400 model, or “SBES: EchoLogger dual-frequency” if you have the D052S/D24S model, and press the blue “plus” button.

  • To access the configuration menu, press on the “three-dot” icon on the upper right corner of the widget and select “Settings”.
