Application Support

Installation, configuration, and debugging support for applications which use our products is provided by the creators of those applications. We are unable to provide support for programs written by others.  Verify that you have properly installed and working hardware, then contact the application provider for support.  Use the verification procedures listed below, and the support forum to determine if you hardware is functioning.  If you determine you have faulty hardware, use the form below for warranty support.

Verifying ThumbDV Hardware

The ThumbDV (and PiDV) appear to the operating system and applications as a serial port.  The only function for these devices is to take digitized voice from an application and return AMBE encoded data back to the application or take AMBE encoded data from the application and return digitized voice back to the application.  All other functions are part of the application, this includes; network connectivity, microphone and speaker, data reporting, linking/unlinking, traffic routing, etc.

A primary test is to see if the serial port appears when the ThumbDV is plugged into a USB port and disappears when it is removed.  Under Windows this can be observed in the Device Manager program.  In Linux and MacOS this will show in the /dev directory as a tty with USB in the name.  Secondarily, programs to determine if your AMBE device is working are included in the AMBE sub-group and it’s associated files section.

Verifying DRAWS and UDRC Hardware

When using Compass Linux (or Raspbian with the driver/device tree added), the command aplay -L will list the sound devices including your DRAWS or UDRC (DRAWS may show UDRC, the sound subsystem is the same).  You can also find the device under /proc/device-tree/hat.  On DRAWS, the GPS serial port is at /dev/ttySC0 and pulse per second device is at /dev/pps0.

Out of Stock / Restocking
