I try to sending serial message from arduino mega to fmb125 via rs232 rx pin, but i cant get it what happen.

I upload this code to arduino mega 2560 :

String n = "hello";
  void setup() {
  void loop() {
    Serial.print(n); //Write the serial data
and i set the FMB 125 RS232 :

Mode = TCP/UDP Ascii
Baudrate = 115200
Parity = None
Message Timestamp = Disable
CMD ID = 6

and then, i connect the arduino mega TX pin to FMB125 RS232 RX pin. So why i get in result at platform : "000011330001000100000200fc0000000be00000000903003601f800f20000ab3a3a0a", "0200ab3a3a0a", or empty not "hello"?
