Arduino uno + 18 channel pololu

Hi, trying to get a servo working on channel 1 of the pololu mini maestro and i just can't get it to work.
I'm also getting the red light which means searial communication error.
I am certain that the wiring is correct.
Here is the Code:

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

void loop()
{
  put(0,3000);
  while(1) //stop it from looping
  {
  }
}

void put(int servo, int  angle)
{
  //servo is the servo number (typically 0-7)
  //angle is the absolute position from 500 to 5500

  unsigned int temp;
  unsigned char pos_hi,pos_low;
  unsigned char buff[6];

  temp=angle&0x1f80;  //get bits 8 thru 13 of position
  pos_hi =temp>>7;     //shift bits 8 thru 13 by 7
  pos_low =angle & 0x7f; //get lower 7 bits of position
  
  //Send a Pololu Protocol command
Serial.print(0xAA, BYTE);    //start byte
 Serial.print(0x0C, BYTE);    //device id
Serial.print(0x04, BYTE);    //command number
Serial.print(servo, BYTE);   //servo number
Serial.print(pos_hi, BYTE);  //bits 8 thru 13
Serial.print(pos_low, BYTE); //bottom 7 bits
}
{/code]

Any help would be appreciated.

sorry about the formatting error of the code.
"any help would be appreciated" is not part of the code as you can probably tell.

bump for help .

You might consider posting the command instructions for your controller or at least a link to them.
