Selecting the Power Source

The Developer Board can be powered using two different power sources:
•
Wall-mount power adapter (default source)
•
External DC power supply
Important:
Two jumpers are used for selecting the power source - P203 for Wall-mount adapter and P204 for
the external DC power supply

Disconnecting Power

The Developer Board and G30 supplies are separated by two jumpers (P200, P201)
that allow disconnecting the power to the Developer Board or to the G30.
Developer Board. Disconnecting power to the Developer Board is generally used to diagnose
a problem that may be caused by the board. This is independent of power supply to the G30,
which will continue to receive power. The Developer Board Power jumper (P201)
positions for connecting and disconnecting power to the Developer Board are shown in
G30. Disconnecting the power to the G30 is generally used to connect an amperometer to the
jumper's two pins to measure the current through the G30. The G30 Power Jumper (P200)
