VIII. Device Reset
There are two types of reset: hardware reset and software reset. The Device can also be rebooted by
switching it off (disconnecting it from both the USB and NMEA 2000 network, or switching off both NMEA
2000 and USB) and then switching it on again (from USB and/or NMEA 2000).
A hardware reset returns your Device to the state in which it was originally purchased. All settings will be
lost and firmware updates will be rolled back. Original files on the internal disk will be restored, all user files
will be deleted or overwritten. To reset the Device:
1. Disconnect the Device from NMEA 2000 or turn off the NMEA 2000 power.
2. Connect the Device to USB (to a laptop or just to the power cable) and disconnect during one second.
Repeat this four times with at least 2 seconds between connections. There should be no LED signals
during this procedure. If there are, it means that you have disconnected the Device too late and need
to start the procedure again.
3. Connect the Device to USB for the fifth time and the LED will turn red. Wait about 5 seconds for it to
change color to green and disconnect immediately. If you have changed your mind, do not disconnect
the Device and wait two seconds for the LED to turn off and the Device to return to normal operation.
4. If you disconnected the Device while its LED was green in the previous step, it will perform the reset
procedure the next time it is connected to USB or NMEA 2000 network. This can take up to a minute.
During this time, the LED will be red. Do not disconnect the Device until its LED starts flashing to
indicate normal operation.
Software reset is the term used for the Python interpreter. You can restart it without cycling the Device
and without breaking the terminal session. In the terminal session (see Section VII), abort the current
program by pressing Ctrl+C and then press Ctrl+D at the Python interactive prompt (REPL). This will reset
the interpreter, and after reset, boot.py and main.py will be executed. You can reset the interpreter with
Ctrl+W instead of Ctrl+D to skip executing of main.py at startup.
