Configuring the output

Configuring the output

LCDs are typically mapped to simulator variables that output numerical values. The following steps demonstrate how to use a display to show the COM1 active frequency heading in Microsoft Flight Simulator 2020 and Microsoft Flight Simulator 2024. See the advanced configuration guide for steps to show more than one simulator value on the display at a time.

Tip

The steps for using an LCD in an X-Plane project are similar. Use the X-Plane DataRef type when configuring the Sim Variable tab.

Add a new output config

Click the Add Output Config button in the main MobiFlight window to open the output configuration dialog.

Filter the output presets

On the Sim Variable tab, use the Filter Preset List dropdowns to filter by Microsoft, Generic, and Radio.

Select the COM 1 active frequency preset

Use the Select Preset dropdown to select the COM ACTIVE FREQUENCY:index preset.

Set the radio index

Since aircraft have more than one radio, MobiFlight will show a dialog to specify the COM radio value to display. Use the dialog to specify index 1.

Select the board and device type for the output

On the Display tab, use the Module and Use type of dropdowns to select your connected board and the LcdDisplay device type.

Select the module to use for display

Use the Display dropdown to select the module that should display the output value. If more than one module is connected in series, use the number dropdown to specify which module in series will display the value.

Format the display output

Replace the Text section sample text with $$$.$$$ to indicate six digits should be displayed with a decimal after the third digit.

Close the dialog and name the config

Click the OK button to close the dialog, then double-click on the New Output Config name in the main window.

Type in a meaningful name for the new config, for example COM1 active frequency, and press enter to apply the change.
