Connecting Sick Laserscanner over ethernet to arduino

Other Hardware Sensors
2

Hello
In the meanwhile we succeeded to ping to our laser scanner from arduino. So we can connection between the two devices. Now we have to send a message to our laser scanner so that he start sending data to arduino. Does anybody have an idea how we can do that? The message that should be send is:
Request: sMN{SPC}LMCstopmeas
HEX string: 02 73 4D 4E 20 4C 4D 43 73 74 6F 70 6D 65 61 73 03
Ping code:

/*
  Ping Example
 
 This example repeatedly sends ICMP pings and sends the result over the serial port.
 
 Circuit:
 * Ethernet shield attached to pins 10, 11, 12, 13

#include <SPI.h>         
#include <Ethernet.h>
#include <ICMPPing.h>

byte mac[] = {0x90, 0xA2, 0xDA, 0x0D, 0x21, 0x19}; // max address for ethernet shield
byte ip[] = { 169,254,228,218}; // ip address for ethernet shield
byte pingAddr[] = {169,254,228,219}; // ip address to ping

SOCKET pingSocket = 0;

char buffer [256];

void setup() 
{
  // start Ethernet
  Ethernet.begin(mac, ip);
  Serial.begin(9600);
}

void loop()
{
  ICMPPing ping(pingSocket);
  ping(4, pingAddr, buffer);
  Serial.println(buffer);
  delay(500);
}

thanks for reading
