How do I set a record per page in a dataTable (dataTable.js)

I do: I get a few records in a DataSet from SQL Server, return to fromEnd sereializados JSON when I receive my reply ajax what convierto format json, now I want to paint them in a DataTable paginated as follows way: if I get 4 registration will be a record for each page, then it will be 4 pages, one record per page, I can not configure the datatable so that it is that way .... I am a newbie in web development, I need your help.

my table is as follows:

<table id="tablaReportes" class="table table-hover">
    <thead id="tbl">
        <tr>
            <th>Fecha y Hora</th>
            <th>Limites alerta (inf/sup)</th>
            <th>Limites accion (inf/sup)</th>
            <th>Usuario</th>
            <th>Ver</th>
        </tr>
    </thead>
</table>

When my document is ready I do the following:

 $('#tablaReportes').DataTable({
    scrollY: 400,
    scrollCollapse: true,
    paging: true,
    searching: false,
    ordering: false,
    info: false,
});

and the way I walk the json object to add content to the table is as follows:

  $.each(json.Table, function (index, item) {

            var aLimites = [{ alertaIn: item.C019alertaIn },
                            { alertaSup: item.C019alertaSup },
                            { accionIn: item.C019accionIn },
                            { accionSup: item.C019accionSup },
                            { obsGrafica: item.C019obsGrafica }];

            $("#tablaReportes").append("<tr><td>" + item.C019fechaRegistro + " ; " + item.C019hora+ "</td>"
                + "<td>[" + item.C019alertaIn + "][" + item.C019alertaSup + "]</td>"
                + "<td>[" + item.C019accionIn + "][" + item.C019accionSup + "]</td>"
                + "<td>" + item.C019NomUsuario + "</td>"
                + "<td><button type='button' class='btn btn-warning' onclick='grafica(" + item.C019SeriesData + ", " + JSON.stringify(aLimites) + "," + item.C019codDetalle + ")'><i class='fa fa-line-chart'></i></button>&nbsp"
                + "<button type='button' class='btn btn-primary' onclick='verObservacion(" + item.C019codDetalle + ")'><i class='fa fa-comments-o'></i></button></td></tr>");
        });

I would appreciate it enough for your help!
