4 Introduction This document provides installation and usage instructions for setting up the client demo, which utilizes the ThingWorx C-SDK, with the Vantron VT-M2M-TC-VM Gateway Device. About the Vantron VT-M2M_TC_VM The VT-M2M-TC-VM is a multi-port gateway device manufactured by Vantron Corporation. It provides Wi-Fi-connectivity, WLAN 3G connectivity, supports data encryption, controls serial communication with other remote devices or computers, and features an Intel ATOM E3845/E3827/E3815 processor and serial, Ethernet, and USB ports for connections. Installation Setup of the VT-M2M-TC-VM device to connect to ThingWorx EMS will first require access to a computer or virtual machine running Linux (Ubuntu or later is preferred). Note: This guide was written for a computer running Microsoft Windows. Modify procedures as needed for your environment. Refer to the Troubleshooting section of this guide for help with frequently asked questions. Compile the Vantron lvdemo Executable This guide explains how to connect ThingWorx to the Vantron VT-M2M-TC-VM gateway device using a custom executable that establishes a secure WebSocket connection to the ThingWorx Platform. (These instructions do not utilize the client demo.) Prerequisites You need access to a computer with Ubuntu or later; earlier versions of Ubuntu have not been tested. You may to run a virtual machine with Ubuntu in order to compile the software. Note: This guide was written using Ubuntu on a virtual machine. All screen shots and instructions assume an Ubuntu machine. 1. Copy each of the following files from this starter kit package to the Ubuntu machine: toolchain file, debootstrap-squeeze-i386.tar.bz2 ThingWorx C SDK, tw-c-sdk v demo executable, lvdemo_src Note: If you are missing the ThingWorx C-SDK, you can download the latest version from support.ptc.com.

5 2. Open a terminal in Ubuntu and type the following to gain root access: sudo su: Above: Ubuntu terminal window. 3. Type the following pre-installations commands into the terminal (installing qtcreator is necessary for making the executable, later in this guide): apt-get install qemu-user-static apt-get install qtcreator 4. Extract the toolchain file to an appropriate directory: tar xjf debootstrap-squeeze-i386.tar.bz2 C /root/ 5. Combine the SDK and lvdemo_src files into the same directory, as follows (the file structures will be similar, but they will not be overwritten): a. Create a directory named tw-c-sdk. b. Put all the files and directories within ThingWorx-C-SDK /tw-c-sdk/ and all the files within lvdemo_src/tw-c-sdk/ into the tw-c-sdk directory. c. Confirm that no files are overwritten. 6. Move the newly created tw-c-sdk directory into the debootstrap-squeeze-i386 directory. 7. Using the chroot command, limit the compile environment to the debootstrap-squeeze-i386 directory, which should now contain all of the files copied in steps 5 and 6: chroot /root/debootstrap-squeeze-i Compile the ThingWorx C-SDK to obtain an intermediate file: cd /tw-c-sdk/examples/steamsensorwithfiletransferandtunneling/linux/ make BUILD=release PLATFORM=gcc-linux-x86-32 cp /tw-c-sdk/build/obj/gcc-linux-x86-32/release/libtw.a /tw-c-sdk/api/tw Copyright 2015 PTC Inc. and/or Its Subsidiary Companies. All Rights Reserved. 3

6 9. Build the lvdemo: cd /tw-c-sdk/build) mkdir out cd out make 10. Copy the new Executable file (lvdemo) to the VT-M2M-TC-VM, using one of the following methods: Using a terminal program a. Connect to the V VT-M2M-TC device from your computer. b. Open a terminal program such as Putty. c. From the terminal program, connect to the Ubuntu machine and copy the file to the VT-M2M-TC using SCP. OR Transfer files to the device over a local area network a. Plug the display into the Vantron VT-M2M-TC-VM device (using either the VGA port or the display port output. b. Plug a keyboard into the USB port on the device. c. Navigate to your Windows network and copy the file from your computer to the Vantron device. Note: Ensure that the run.sh, settings.json, and lvdemo and so directories are located under the same directory on the VT-M2M-TC device (preferably all in the /opt/lv-demo/ directory). See the next section for connecting to the Vantron device. Please note that you should NOT move on to section 3 of this guide until the lvdemo executable file has been copied to the VT-M2M-TC-VM device. Connect the VT-M2M-TC to a Monitor Peripheral 1. Connect a Panel-7 display to VT-M2M-TC- VM. Note: If no display is shown then view the back of Panel-7 and select to switch the display on. 2. Connect a USB keyboard to the VT-M2M-TC-VM. 3. Power on the VT-M2M-TC-VM, open a terminal window and type sudo su ; the default password is vantron. Copyright 2015 PTC Inc. and/or Its Subsidiary Companies. All Rights Reserved. 4

7 4. Open a Linux terminal, such as Putty, to connect to the VT-TC-VM device. Configuration and Setup This starter kit includes a zip file containing the entities associated with the Vantron Demo ThingWorx mashup. You need to set up those entities in your ThingWorx Platform. Import Demo Entities into your ThingWorx Platform 1. Log into your ThingWorx Platform (Composer 6.0 or later), and import the entities as a whole package. 2. Note the URL and port of your ThingWorx Platform server. Copyright 2015 PTC Inc. and/or Its Subsidiary Companies. All Rights Reserved. 5

8 3. Create an Application Key on this ThingWorx server. Make note of the Application Key (also known as AppKey ) as you will need to use it again later in this guide. Setting up a WebSocket Connection 1. On the VT-M2M-TC-VM, via Putty or a similar Linux terminal program, type: Ifconfig This returns the changes to the network information. 2. Verify internet connection. Type ping or other Internet address. The following steps are needed for testing out how the data gathered from the VT-M2M-TC VM device is reported. These steps are to be used with a sense plate or similar sensor connected to the VT-M2M- TC-VM via USB cable. This next steps ensure the system recognizes the USB device index for the sensor plate. 3. Create a hyperlink: Copyright 2015 PTC Inc. and/or Its Subsidiary Companies. All Rights Reserved. 6

9 4. Copy the file 99-usb-serial.rules to /etc/udev/rules.d/: The contents of the file 99-usb-serial.rules should be the following text: SUBSYSTEM=="tty",ATTRS{idVendor}=="1a86", ATTRS{idProduct}=="7523",SYMLINK+="ttySAD P" 5. Connect the Sense plate by USB cable to the VT-M2M-TC- VM device. 6. Go to the target catalog directory by typing the following: cd /opt/lv-demo 7. Configure the IP address and port number of the ThingWorx Platform to which you want to connect (i.e, the Platform configured with the Vantron Mashup) by editing the settings.json file in this directory. Modify it using the vi settings.json command in Linux. In this example, the Platform server location is set to :8443. For your use, point the settings.json server IP and server port to your SSL-enabled server and the port 443. Be sure to supply the correct appkey as well. These may be generated in the ThingWorx platform from the appkey section on the home Composer screen 8. To start the data-reporting demo program, run the run.sh file by typing the following command: Copyright 2015 PTC Inc. and/or Its Subsidiary Companies. All Rights Reserved. 7

10 ./run.sh If the program executes properly and the configuration is correct, you should see an output in the terminal window similar to this: It is important that you see the Websocket_connected! output to confirm a successful connection to the ThingWorx Platform. Assuming you have a successful connection, continue with the next step in this procedure. 9. Navigate to the URI of the ThingWorx Platform server, configured in settings.json earlier, and do the following: a. Click the Monitoring drop-down and select Subsystems.
