02 RDM6300 on Mega 2560 with weird characters

Hi

I am trying to put two RDM6300 RFID modules to run on an Arduino Mega 2560.

through the function .listen () I was able to make both modules respond, but the information read on the serial port is with weird characters.

I connected the TX and RX pins of the modules on ports A11 through A14 as described in the code below:

#include <SoftwareSerial.h>

#define A11 65
#define A12 66
#define A13 67
#define A14 68

SoftwareSerial Reader1(A14, A13);// RX and TX
SoftwareSerial Reader2(A12, A11);// RX and TX

int rfid, i;
char newtag[14];

void setup()
{
  Reader1.begin(9600);    // start serial to RFID1 reader
  Reader2.begin(9600);    // start serial to RFID2 reader
  Serial.begin(9600);     // start serial to PC 
}

void loop()
{
  
  Reader1.listen();
  if (Reader1.available() > 0) 
  { 
    Serial.println();
    Serial.println();
    Serial.println("Reading RFID Tag...");
    delay(100);

    for (i=0; i < 13; i++)
      {
          rfid = Reader1.read();
          newtag[i]=rfid;
      }
     Reader1.flush();
     Serial.print("RFID Tag No:");
     Serial.print(newtag);

  }
  
  Reader2.listen();
  if (Reader2.available() > 0) 
  {
    Serial.println();
    Serial.println();
    Serial.println("Reading RFID Tag...");
    delay(100);

    for (i=0; i < 13; i++)
      {
          rfid = Reader2.read();
          newtag[i]=rfid;
      }
     Reader2.flush();
     Serial.print("RFID Tag No:");
     Serial.print(newtag);

  }
}

so when I load the sketch on the Arduino, after opening the serial port and positioning the cards on the receiving antennas, I get this:

Reading RFID Tag...
RFID Tag No:C000000C00CC

Reading RFID Tag...
RFID Tag No:

⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮

Reading RFID Tag...
RFID Tag No:⸮0000000FF⸮

Reading RFID Tag...
RFID Tag No:TS⸮⸮460058B

Reading RFID Tag...
RFID Tag No:⸮460058BD5EF

Both antennas are capable of receiving and transmitting signal, but deliver strange characters.

Thanks for advance.

I doubt the Tag sends back ASCII.... or does it?

this is one of my doubts too. in fact the two antennas are delivering information when I put the tag (as I show on the first post). but I do not understand what information is. ascii

somebody can tell what's wrong?

If you have doubt, look up the datasheet of the reader (chip). It will tell you what it sends back.
