Configure the Touch Screen Display
Connect the USB cables, HDMI cable and power cables to the GTN650. The GTN750 screen should now show the Windows desktop background. Set the resolution to 1366x768 or 1280x720, this can make the calibration easier.
Once the PenMount driver is installed, open the 'PenMount Control Panel' application.
The first step is tell your PC which monitor is associated with the touch screen. Click on the 'Multiple Monitors' tab and then click the 'Map Touch Screens' button.
Follow the on screen instructions. Each of your connected screens will turn blue, press the 'S' key on your keyboard to skip, when the blue screen is displayed on the GTN650 screen, touch the screen to complete the process.

Click the 'Standard Calibration' button then follow the on screen instructions. Please ensure 'Turn off EEPROM storage' is NOT ticked.
Touch and hold each corner where indicated.
When complete, click 'OK' and then 'OK' again to save the calibration and close the control panel application.
Your RealSimGear GTN650 and/or GTN750 should now be ready to use. By default it will appear as NAV/COM 1 and you will see it in the connected devices window of the RealSimGear Plugin/Add-on. When you turn the knobs or press a button the ‘message’ and ‘command’ section will change accordingly.
NOTE: If the GTN650/750 buttons and knobs are not working, please check to make sure the device shows up in the RealSimGear Plugin/Add-on Connected Devices interface (if not, you may need to perform a Rescan) and that you have selected the correct GTN Device Type that matches how you have configured the Reality-XP or the MSFS GTN software.
GTN 1 = Device Type COM1 (Usually GTN750)
GTN 2 = Device Type COM2 (Usually GTN650)
Move the GTN650 window to the RealSimGear GTN650 display, note you will need to ‘pop out’ the window first, this can be done using the Reality-XP plugin menu.
