Cannot control servos through 32-servo-controller on Aurduino Duamilanove I have servo (TowerPro sg90) connected to 32 servo controller (this one) through UART interface (RX-TX, GND-GND). 
Seller provide documentation how to connect and control my servos, but it isn't work. 

Servo work if I connect it indirectly to Arduino. Controller indicate that it is working too (photo below - red led).

I already try different servos. Also try use provided software to control servos from pc through Mac/PC. But it's interface is unreadable for me. I tried different options but servos not responding. 

Sketch code below (from sellers examples):

void setup() {
  Serial.begin(9600);
}

void loop() {
  Serial.print("#3P500T2000\r\n");
  delay(2000);
  Serial.print("#3P1500T2000\r\n");
  delay(3000);
  Serial.print("#3P2500T2000\r\n"); 
  delay(2000);
  Serial.print("#3P1500T2000\r\n");
  delay(2000);
}

Sorry if it post duplicate some, but I cannot google this problem.
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.
