            Tech-Link 2.0 Software Installation 
      
        - Download the Tech-Link 2.0 software by 
        clicking on the
        "Download 
          Software" link above.
 
        The file "Tech_link_20.zip" will be found in the specified download 
        location. 
  
        -  Unzip the file using the windows 
        explorer.  The folder "Tech-Link 2.0" is inside the zip file.
 
  
        - Copy this folder "Tech-Link 2.0" 
        to the desired location such as the Desktop, C drive etc.,  using the windows 
        explorer.
 
  
        - Using the windows explorer, browse to 
        this folder and create a shortcut to the executable 
        "Tech_Link_20.exe" using the windows explorer.  
 
        Copy the shortcut to your desktop. 
  
        - Microsoft .NET 4.5 (or later)  
        framework is required for Tech-Link to operate.  
 
        You can easily check which versions you have installed by viewing the 
        "Programs and Features" located in the Control Panel. 
        You can download it
        
        HERE.  If you are not sure, you can just install it anyway 
        since it won't hurt anything. 
  
        - To test the software installation, 
        double-click on the "Tech_Link_20.exe" shortcut.
 
        You should see the error message window shown below at this point.  
        If not, re-check the above steps. 
  
        - Folders containing the TH-2 software 
        will also be added to the folder "Tech-Link 2.0".  They will be 
        named TH, VT, UM etc.
 
        For now, proceed to the next step
            USB 
            Driver Installation.

            USB Driver Installation 
  
      
            Step 1 
      
        - For Windows 7 go to STEP 2 below.  
        For Windows 8/10 continue.
 
  
        - Windows 8/10 enforces driver signatures 
        by default and must be disabled to install the USB driver.  
 
        The USB driver itself is supplied by Microsoft and is signed.  Just 
        the "inf" install file is unsigned. 
        Use the following steps to temporarily disable driver signature 
        enforcement. 
        Note: youtube has many instructional videos on this subject. 
  
       
      
      
       
        3. 
      Your computer will restart and then you will be able to install the USB 
      driver.  
         On the next restart,  
      the driver signature enforcement will be re-enabled. 
  
      
            Step 2 
      
        - Using the windows explorer, browse to 
        the "Driver" folder under the main folder "Tech-Link 2.0".  
 
  
        - For Windows 64 bit,  double-click 
        the executable "Tech-Link_2X_USB_Driver_Installer_x64".
 
        For Windows 32 bit,  double-click the executable 
        "Tech-Link_2X_USB_Driver_Installer_x86". 
         
        Depending on permission settings, you may need to run the executable as 
        the administrator. 
        This can be done by right-clicking the target file and selecting "Run as 
        administrator". 
  
        -  This will begin the driver 
        installation process by starting the wizard.
 
 Click - Next. 
 Click - Install this driver software anyway. 
 Click - Finish. 
  
        - This completes the driver install.  
        You can now proceed to download/install application software.
 
        The software application download section can be found at the top of the
        TH-2 XPR

      Modes
 There 
      are two main modes of operation Program and RT. 
       
      In Program mode you can load an application file, load/save a 
      settings file and modify the settings statically. 
      To enter this mode, start with all power turned off, connect the TH-2 to 
      the PC via the USB cable and run Tech-Link. 
      The mode status on the top right 
      of the Tech-Link window will indicate "Program mode". 
      You can now use the menu items under Program and Settings. 
      In RT mode you can modify the application settings in real time (RT). 
      You can see the
      changes applied as you 
      make adjustments to the settings etc. 
      This mode is entered by first entering Program mode (see above), with USB 
      connected and Tech-Link active, 
      then turning on the TH-2 external power and radio power (Tx, Rx, servos etc.). 
      From the Tools->Enter RT Mode dialog click on the "RT mode" button. 
      The mode status on the top right of the Tech-Link window will indicate "RT 
      mode". 
      You can now use the menu items under Settings and Tools. 
      Note: RT mode can only be entered from Program mode.

      RT Dashboard  -
      This dialog allows you to see the values of the five external gain settings. 
                                     
      Depending on the application running, the values can have a range of 
                                     
      positive (0..100) or positve/negative (-100..100) numbers representing a 
      percentage. 
                                     
      In addition, the X input gain has the value of the "Pulse Width" in units 
      of microseconds 
                               
      displayed. This is the actual PPM pulse width sent from the receiver.
