Transducer AD104C and RS232 Shield

Hello everybody !
First, sorry for my english !
I need help concerning an AD104C transducer, connected to a Shield RS232 V2 from LinkSprite.
I use an Arduino Uno. The problem is that I can't read any data from the transducer ...
On the Shield RS232, I use Pins D7 as RX and D6 as TX. I use a simple sketch to read the data :

#include "Arduino.h"
#include <SoftwareSerial.h>

SoftwareSerial test (6,7); // (RX,TX)
unsigned char entree;
 
void setup ()
{
  //Serial.begin (115200);
  //test.begin (115200);
  Serial.begin (9600);
  test.begin (9600);
  Serial.println ("begin initial Serial!\n");
}
 
void loop ()
{
  delay (2);
  while(test.available () > 0)
  {
      entree=test.read ();
      Serial.print (entree,DEC);
      Serial.print (' ');
  }
  Serial.println();
  delay (1000);
}

I will put some pictures of my project if necessary.
Thank you in advance for you help !

Well,

The commands you send to the 104c are a bit weird. Dit you preset the board with aed panel?
