I see that Maretron’s DSM150, DSM200, and DSM250 displays have a J2K100 configuration setting called "Reset Factory Defaults"; what is this?

Maretron’s DSM150, DSM200,and DSM250 displays have a J2K100 configuration setting called "Reset Factory Defaults" which is used to return the J2K100 to its factory settings. Resetting the J2K100 to factory defaults sets the J1939 source address back to 0, sets the NMEA 2000 engine instance back to 0, sets the NMEA 2000 transmission instance back to 0, disables J1939 diagnostic messages, and returns PGN enable/disable back to the factory defaults.
