Wall Mount Adapter Operation
To Use a Wall Mount Adapter
1. Connect the Wall mount adapter to the Power Adapter connector (J210) ( Figure 2-10 )
2. Verify that jumper P203 is connected and jumper P204 is disconnected (default setup).
Important:
Verify that the Wall mount adapter is not connected to the USB connector (J380).
Figure 2-10: G30 Developer’s Kit Wall Mount Adapter Connector
The Wall Mount Adapter connector is located at the rear of the Developer Board,
immediately to the left of the Power On/Off switch.
The Wall Mount Adapter connector pinout is described in Table 2-1 . The adapter supplies a
constant 4.5 V, which is regulated to a nominal 4.1 V on the Developer Board.
Important: The G30 includes an on-board protection circuit for cases in which the USB
connector is connected by mistake to the Wall Mount Adapter connector (J210).
If by mistake, the Mini AB USB cable is connected to J210 instead of J380, the on
board Wall mount adapter is disabled, preventing unrequired load on the host
computer.
