        byte[] cSN = new byte[8];           
        byte[] sw12 = new byte[2];
        string strsw12 = "", errdes = "", result = "";

        test1_2 = new Initialisation();

        test1_2.logmode = Convert.ToInt32(ConfigurationSettings.AppSettings["LogMode"]);
        test1_2.iChipType = GetChipType(lblChipType.Text.Trim());

        //--initialise test
        result = test1_2.Initialise(1, **configXML.fnSamSlot**, configXML, ref cSN, ref sProgress1_2, ref lProcess1_2, ref sw12, ref errdes);
