3. AITP (Odometer)
This application shows how to use AITP to interact with the odometer. You can ask odometer status,
set the automatic odometer trigger and it shows the odometer data as these arrive from the AITP.
Sample code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace Digitax.Sample.Odometer

//odometer object

{

//init aitp in MDT/MCU "COM4:" 19200 on ForceOne "COM3:" 38400
