FAQ

Q: How do you apply the 'speed of sound setting' to the Sonarmite readings? Is it a setting within the sonarmite or can the recorded data be adjusted with reference to the tables in the manual?

A: You can use either the Sonarmite Android App on your phone /tablet and connect to the unit using Bluetooth, or use a PC with WCOM 32 terminal software and the supplied serial cable.

 

Once connected to the unit, use the CTRL+F keys to change the output format to SYSTEM format. Once in SYSTEM, you will see the sound velocity around 1500. You can then use the CTRL+I or CTRL+D keys to increase or decrease the SV value as needed. Once set, use the CTRL+S keys to save your settings.

 

You can now change the format back to your required output.

Q: My HyDrone is beeping and/or my throttle is uneven and/or I don't have reverse; what do I do?

A: Slowly beeping (about once a second)

  • The slow beep of the ESC (Electronic Speed Controller) means it is not receiving signal.

  • An unpaired or damaged receiver can cause this, or a connection break of the red, white, and black wire set.

A: Rapidly beeping

  • If it is a rapid beep, the ESC is warning you that the remote control's throttle stick is not centered.

  • If the throttle stick is centered and you are still having this issue, see the steps below:

A: My throttle is uneven / it won't reverse

  • Start with the remote control on (for ASV Hydrones, the Autonav has to be on and armed)

  • Ensure all trims are set to zero using the four trim tabs located on the remote

For RCV

  • Move the Left stick full forward.

  • Turn the left pontoon on.

  • After two beeps, move the stick back down to center.

  • The ESC will emit a series of tones indicating the new center has been set.

  • Repeat this process on the right side.

  • If the calibration is not centered, this can be repeated as many times as needed.

For ASV

  • Move the right stick fully forward.

  • Turn the left pontoon on.

  • After two beeps, move the stick back down to center.

  • The ESC will emit a series of tones indicating the new center has been set.

  • Repeat this process on the right pontoon still using the right stick.

  • If the calibration is not centered, this can be repeated as many times as needed.

 

*If you have performed the throttle calibration steps above and still don't have reverse, The ESC will need to be programmed. It is recommended to call in and ask for assistance.

Q: How do I  configure GPS rovers to work with the AutoNav?

 

A: Lemo Cable Config:

  • Talker ID: $GP

  • NMEA Stings: GGA@5Hz, RMC@5HZ. If you have an EchoBoat-160, it needs to have HDT@5Hz as well. 

  • Baud Rate: 38400 for HyDrone, 57600 for Echoboat-160.
