I also tested:

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

void loop() {

delay(1000);

Serial.write(0x02);
Serial.write(0x00);
Serial.write(0x00);
Serial.write(0x00);
Serial.write(0x00);
Serial.write(0x02);

delay(1000);

}

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

void loop() {

delay(1000);

Serial.write(02);
Serial.write(00);
Serial.write(00);
Serial.write(00);
Serial.write(00);
Serial.write(02);

delay(1000);

}

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

void loop() {

delay(1000);

Serial.write("02 00 00 00 00 02);

delay(1000);

}
