Arduino to Smart Motor troubles

Hello,

My research group is unable to set up communications to control an Animatics Smart Motor (3440D) with an Arduino (Mega). We are running the following code for setup and running:

bool initialiseSteering();

void setup() {
  Serial.setTimeout(2);
  Serial.begin(9600);
  
  initialiseSteering();
}

bool initialiseSteering() {
  Serial1.begin(9600);
  Serial1.print("WAKE ");
  Serial1.print("MP ");
  Serial1.print("BRKRLS ");
  Serial1.print("O=0 ");
  Serial1.print("A=500 ");
  Serial1.print("V=1300000 ");
  
  Serial1.print("P=8000 ");
  Serial1.print("G ");
}

Yet the Smart Motor fails to move.
Plugging directly into a computer with the SMI software running, the Motor runs fine in playground mode, but initialisation through the SMI console alone does not work. Are we doing the set up incorrectly?

Thank you,

Harry.
