The power supply voltage provided via the CN19 AC/DC connector may be in a range between 9 and 32V DC or 7 and
23V AC. Before you turn the development system on, it is necessary to place jumper J11 in the EXT position.
When the development system is powered, it is necessary to set switch marked POWER SUPPLY to the ON position. As
soon as the development system is turned on, a green LED marked POWER will automatically illuminate.
