David,

When I paste in.

byte command[] = "\x00\x00\x00\x00\x00\x01Z00\x02""AA\x1B\x20\x1C\x31PAIK Auditorium\x04";

void setup() {
  Serial.begin(9600);
  Serial2.begin(9600);
  delay(1000);
  Serial.write(command, sizeof(command) - 1);
  Serial.println();
  for (size_t i = 0; i < sizeof(command) - 1; i++) {
    if (command[i] < 0x10)
      Serial.print('0');
    Serial.print(command[i], HEX);
    Serial.print(' ');
  }
  Serial.println();
  
  Serial2.write(command, sizeof(command) - 1);
}

void loop() {
}

I get the response from the sign "1PAIK Auditorium" scrolling and the color is constantly changing.
