Trevon Martin • July 10, 2026

If you need to restore the BG-MVS4X4-CV to its factory default settings, you can do so by connecting to the unit via RS-232 and sending the factory reset command.

  • Terminal software (such as Docklight)

Step 1: Connect to the Unit

  1. Connect the 3-pin RS-232 port on the rear of the BG-MVS4X4-CV to your PC using a 3-pin Phoenix-to-USB RS-232 adapter.
  2. Open your terminal software (such as Docklight).
