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.
