X10 Project Problem

Actually am working with X10 protocol. My idea is send X10 commands with a PSC05 and Arduino Uno and in other room receive those X10 commands with other PSC05 and other Arduino Uno and with this one connect TV, Lamp, etc.
My problem is that I sent commands like: A5 or whatever command and ever sent and receive the same command when I check the debug:

SC-1111 HouseCode-74 UnitCode-13 CMND-31

This is my code and I hope that someone help me please:

Transmissor X10 Source Code:

#include <x10.h>
#include <x10constants.h>

#define zcPin 2
#define dataPin 3


x10 myHouse =  x10(zcPin, dataPin);

void setup() {
  Serial.begin(9600);
  digitalWrite(zcPin,HIGH);
  pinMode(13,OUTPUT);
}

void loop() {
  Serial.println("House A Code 5 ON:");//Print action
  myHouse.write(HOUSE_A,UNIT_5,1);//Sent A5 command once
  myHouse.write(HOUSE_A, ON,1);//Sent turn on A5
  myHouse.debug();
  digitalWrite(13,HIGH);//Turn on the LED in pin 13 for know if a X10 command is written
  delay(500);//A little blink for LED in pin 13
  digitalWrite(13,LOW);//Turn off the LED in pin 13
  delay(4000);
  Serial.println("House A Code 5 OFF:");//Print action
  myHouse.write(HOUSE_A,UNIT_5,1);//Sent A5 command once
  myHouse.write(HOUSE_A,OFF,1);//Sent turn off A5
  myHouse.debug(); 
  digitalWrite(13,HIGH);//Turn on the LED in pin 13 for know if a X10 command is written
  delay(500); //A little blink for LED in pin 13
  digitalWrite(13,LOW);//Turn off the LED in pin 13
  delay(2000); //Delay for sent a new X10 command again  
}

Receive X10 Source Code:

#include <x10.h>
#include <x10constants.h>

#define ZCROSS_PIN     2               // BLK pin 1 of PSC05
#define RCVE_PIN       4               // GRN pin 3 of PSC05
#define TRANS_PIN      5               // YEL pin 4 of PSC05
#define LED_PIN        13              // for testing 

x10 SX10= x10(ZCROSS_PIN,TRANS_PIN,RCVE_PIN,LED_PIN);// set up a x10 library instance:

void setup() {
  Serial.begin(9600);
  delay(500);
  Serial.print("x10 receive/send test");
  pinMode(13,OUTPUT);
  pinMode(12,OUTPUT);
  digitalWrite(2,HIGH);
  digitalWrite(4,HIGH);
}

void loop(){
   if (SX10.received()) {      // received a new command
   SX10.debug();                       // print out the received command
   SX10.reset();
   if (SX10.houseCode() == 'A' && SX10.unitCode() == 5  ){
   byte cmndCode = SX10.cmndCode();
   if(cmndCode == ON) {
   digitalWrite(13,HIGH);
   delay(3000);
   digitalWrite(13,LOW);
   delay(500);
      }  
   else if(cmndCode == OFF) 
   {
   digitalWrite(12,HIGH);
   delay(1000);
   digitalWrite(12,LOW);
   delay(500);  
      } 
    }
  }
}

How are you wired to the PSC05s?
You do have a common ground?
I don't think you should use delays as they stop your Arduino for that amount of time.
Can you actually turn on/off an existing X10 wall light with your transmitter sketch?
Does your receiver sketch respond to a X10 hand held remote?
