Welcome to our new website www.MTXTunnel.com. With this you can keep up to date with all of the news, upadates and new features that we are incorporating into MTXTunnel. We will also include practical examples in order to make using MTXTunnel simple. We will try to make everything clear and explain everything well.

We hope you like it. If you have any questions don’t hesitate to ask, we will be happy to help you.

In this example, I am going to show you how to configure the MTXTunnelGPS. The device is installed in a vehicle and periodically it sends its GPS position and I/Os (digital/analog inputs and outputs) to a PC server. As well as sending the GPS position, an approximate location needs to be obtained by GSM cells in case there isn’t GPS coverage (for example, when the vehicle is in a basement, garage, …). It also activates the Telnet service in the MTXTunnelGPS so that it can  connect remotely and can carry out maintenance operations.

Let’s look at the example scenario in detail:

• GPS positions need to be sent to a central server from an MTXTunnelGPS installed in a lorry.  It needs to be sent with the IP 200.201.202.203y and TCP port 20010.

• MTXTunnelGPS must read the GPS position every 30 seconds and send the position to a TCP socket server in real time.

• In case there is no GPS coverage, the modems sends a KeepAlive frame every two minutes along with the necessary information to be able to localize the vehicle through GSM cell tracking.

• Telemetry data (digital inputs) must be sent too from certain devices that are connected to the modem’s digital inputs.

• You must be able to remotely access the modem’s settings to be able to monitor data like GSM coverage  or read the modem’s analog inputs which are connected to other devices at any given moment. To do this you need to have enabled Telnet in the modem. For security reasons, you can only access the Telnet service from the central IP address 200.201.202.210.

Proposed solution with MTXTunnelGPS

MTXTunnelGPS configuration file for the proposed solution above:

You have to enter this into the modem’s MTXTunnelGPS.jad file to be able to run the application as described in the scenario.

If you configure the MTXTunnelGPS with these settings, the device will periodically send the GPRS position to the PC Server. You can find more information on “sending data frames” in the MTXTunnelGPS manual, (specifically Annex 1, page 73).
