Appendix A Code Examples (.NET)

Initialize Device

MTDevice device = new MTDevice(); if (device != null)
{
        device.setConnectionType(MTConnectionType.USB);

        device += OnDeviceConnectionStateChanged; 
        device += onDeviceResponseMessage; 
        device += onDeviceNotificationMessage;
}

Connect to Device

if (device != null)
{
device.openDevice();
}

Send Data String to Device

String dataString = “C00101C10100C20114”; 
device.sendDataString(dataString);

Send Data Bytes to Device

Byte[] dataBytes = new Byte[9] {0xC0,0x01,0x01,
                                0xC1,0x01,0x00,
                                0xC2,0x01,0x14};
device.sendDataBytes(dataBytes);

Send MTCMSMessage to Device

MTCMSMessage message = new MTCMSMessage(0x01,0x00,0x14, 0xC4, null); 
device.sendMTCMSMessage(message);

Send MTCMSRequestMessage to Device

MTCMSRequestMessage request = new MTCMSRequestMessage
                                (0x00,0x14, 0xC4, false);
device.sendMTCMSMessage(request);

Receiving Connection State Updates from Device

protected void OnDeviceConnectionStateChanged(object sender, 
MTConnectionState state)
{
    if (state == MTConnectionState.Connected)
    {
        sendToDisplay(“Device is Connected”);
    }
    else if (state == MTConnectionState.Disconnected)
    {
        sendToDisplay(“Device is Disconnected”);
    }
}

Receiving Response Message from Device

protected void OnDeviceResponseMessage(object sender, 
MTCMSResponseMessage response)
{
        sendToDisplay(“[Response Message]” 
        sendToDisplay(“AppID: ” + response.getApplicationID()); 
        sendToDisplay(“CommandID: ” + response.getCommandID());
        sendToDisplay(“ResultCode: ” + response.getResultCode());
}

Receiving Notification Message from Device

protected void OnDeviceNotificationMessage(object sender, 
MTCMSNotificationMessage notification)
{
        sendToDisplay(“[Notification Message]” 
        sendToDisplay(“AppID: ” notification. getApplicationID() ); 
        sendToDisplay(“CommandID: ” + notification.getCommandID());
        sendToDisplay(“ResultCode: ” + notification.getResultCode());
}

Close Device

if (device != null)
{
        device.closeDevice();
}
