In addition to the methods mentioned above, the DevDevil can be powered with an AC to DC adapter. The output voltage
of any device must be between 9 and 15 volts DC and the barrel used must be center positive. For this configuration, the
Voltage Select jumper must be placed on the 9-15V Input side and the Power Select jumper set to input. This input can be
useful when communicating to the device via a computer serial port.
