I can''t send XBee(with Arduino) data to my pc Xbee Data

I want to send data from XBee which is connected to arduino mega to another Xbee which is connected to my pc and I want to see the message on X-CTU. I got 2 XBee explorers ,
I use one of the xbee explorers to connect one of the xbees to the computer and the other xbee explorer to connect the transmitter xbee and the arduino. I think XBee explorers working same with XBee Shield.

On XCTU configuration

Receiver Xbee(which is connectedto pc (COORDINATOR));
CE enabled
PAN ID: 1234
API ENABLED
others default

Transmitter XBee (which is connected to arduino(ROUTER))
JV channel verification ENABLED
PAN ID: 1234
API with ESCAPING (Mode 2 )
others default

#include <XBee.h>
XBee xbee = XBee ();
uint8_t payload []= {0,0,0,0,0,0,0};
XBeeAddress64 addr64 = XBeeAddress64 (0x000000000,0x000000000);
ZBTxRequest tx = ZBTxRequest(addr64,payload,sizeof(payload));

void setup(){
Serial.begin(9600);
xbee.setSerial(Serial);

}
 
void loop(){
   
  
payload[0]='1';
payload[1]='2';
payload[2]='3';
payload[3]='4';
payload[4]='5';
payload[5]='6';
payload[6]='7';
xbee.send(tx); 
delay(1000);
}

Arduino MEGA
XBee S2C
Xbee Explorers Fundino XBee Explorer

Connecting XBee to Arduino through xbee explorer

RX on Explorer to Arduino Serial1 TX
TX on Explorer to Arduino Serial1 RX
Vcc to 3V
GND to GND
