Linux
Download this .AppImage file. Edit the permissions of the .AppImage to have executable
permission with the command line: chmod +x ping-viewer-linux.AppImage . Open the
AppImage by double clicking it, or execute it from the command line: ./ping-viewer-
linux.AppImage .
Remember to run the commands in the same path where the Appimage file is.
Connection Setup
To begin using the device, connect it to a USB - UART converter that operates on 5V like this
Blue Robotics adapter. Then connect the converter to your computer's USB port. The Ping
Viewer application should automatically detect your device and begin displaying data. If it
does not, check the FAQ and Troubleshooting guide.
Visit the Connection Settings menu for more connection options.
Principle of Operation
The Blue Robotics Ping Echosounder is a 1-dimensional sonar that measures the distance to
objects underwater. The device emits a brief 115 kHz acoustic pulse from the transducer at
the face of the device. The device then measures the strength of returned acoustic energy
and the amount of time for the returned energy to reach a significant level. The sound wave
travels through water, and reflects or 'echos' off of solid objects, and travels back to the
device. The device then calculates the distance to the solid object with the equation distance
= known speed of sound in water * (measured time for echo to return / 2) .
