Note: The RealSimGear GTN750 requires you purchase separately the Reality-XP GTN750 software (X-Plane, FSX, or P3D) or the PMS50 GTN software (MSFS).  The RSG750 will not function without one of these 3rd party software.

Connect the cables

Connect an HDMI cable (supplied by customer), and the 2 USB cables between the GTN750 unit and your PC (any USB is fine) along with the 12vDC power supply.  Turn on your PC and the display will show a second windows or mac desktop.  The image displayed on the GTN750 will be inverted, to correct this you will need to adjust the display settings.

Touch Screen Driver Setup

Download the PenMount touch screen driver software here and install. When asked, select the default option to use mouse pointer mode. Note you will need to restart your PC after the installation is complete.

Configure the display

Connect the USB cables, HDMI cable and power cables to the GTN750. Go into the Windows display settings and make sure the GTN750 display is set to 'Portrait (Flipped)' mode and that the multiple displays are configured to 'Extend these displays'.  The GTN750 screen should now show the Windows desktop background.

Once the PenMount driver is installed, open the 'PenNMount 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 GTN750 screen, touch the screen to complete the process.

Complete the calibration process, click on the 'Device' tab, then click the 'Configure' button. 

Click the 'Standard Calibration' button then follow the on screen instructions.

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 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 GTN750 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 PMS50 GTN.

  • GTN 1 = Device Type COM1

  • GTN 2 = Device Type COM2

Move the GTN750 window to the RealSimGear GTN750 display, note you will need to ‘pop out’ the window first, this can be done using the Reality-XP plugin menu.
