Configuration File
The controller will automatically save all of the
configured parameters to a file that can be accessed by
connecting a laptop to the controller with a micro USB
cable. This file can be used to copy the setting of one
board to another board.
The file is located in the main directory of the
controller and is labeled "MG_Config". Copy this file to
a location on the laptop and then disconnect from the
first board. Connect to the second board and copy the
file to the second board. Disconnect the laptop from
the second board and power cycle the controller. The
second board will now have the same settings as the
first board.
