 In M2K mode the board is plugged into ADALM2000. After that, the programable user supplies of ADALM2000 can be used as usual, but they will source more current. The jumper on the connector P7 must be in M2K- position and the jumper on the connector P6 must be in M2K+ position.  In M2K mode the board is plugged into ADALM2000.

 +The board can be adjusted such as the output voltage is double or triple than the value set from the M2K. This feature is only available in M2K mode, and it is activated by soldering or desoldering the solderjumpers on the bottom of the board according to the table.  
 +You can find the table with the soldering instructions on the bottom of the board.
