2.2.5 Step 5 — Connect Power
Once all the other connections have been made, you can connect power to the Prototyping
Board.
If you have the universal AC adapter, prepare the AC adapter for the country where it will
be used by selecting the appropriate plug. Snap in the top of the plug assembly into the slot
at the top of the AC adapter as shown in Figure 5, then press down on the plug until it
clicks into place.
Connect the AC adapter to 3-pin header J1 on the Prototyping Board as shown in Figure 5
above. The connector may be attached either way as long as it is not offset to one side—
the center pin of J1 is always connected to the positive terminal, and either edge pin is
ground.
Plug in the AC adapter. The
PWR
LED on the Prototyping Board next to the power con-
nector at J1 should light up. The RCM4400W and the Prototyping Board are now ready to
be used.
NOTE: A RESET button is provided on the Prototyping Board next to the battery holder
to allow a hardware reset without disconnecting power.
To power down the Prototyping Board, unplug the power connector from J1. You should
disconnect power before making any circuit adjustments in the prototyping area, changing
any connections to the board, or removing the RCM4400W from the Prototyping Board.
