Cannot control servos through 32-servo-controller on Aurduino Duamilanove
There is one connection missing - the one that powers the servo and board.

At the moment your servo board is getting a small amount of power through the RX pin - disconnect it immediately, you are damaging it.

You need to provide +5V to the +5V terminal block, and also a suitable voltage (+5V should do) to the VCC on the terminal block.
