Setting up OpenTX Companion

The first thing is of course to download and install the appropriate version of OpenTX Companion for your system from the OpenTX home page.

Once the program is launched, you will see the main window.

To open the Edit Settings window:

  • Windows -> Settings -> Settings

  • Mac -> Companion 2.2 -> Preferences

Settings menu

There are three tabs:

Radio Profile

  • Profile name - Name the profile for the hardware.

  • Profiles: Allows storing different setting sets and easily switching

    between them. For example, if you have 2 different radios with

    different firmwares or board types it is not convenient to have to

    redo all settings (firmware selection, ticking options,...) every

    time you want to do operations on the other radio. So you can

    configure all settings, choose an empty profile with the number box,

    type a name to identify the particular radio, and click save. Do the

    same for the second radio. You will now be able to select the

    correct profile for the radio you are about to work on with the

    profile selector button and menu entry on OpenTX companion's main

    window. Note that the profiles can also store and retrieve each

    radio's stick calibration and hardware settings (voltage alarms,

    audio modes,...) from the General Settings page of an open

    document. This allows copying a document from one radio to the other

    without needing recalibration or reentering the hardware settings.

  • Radio type - Choose the proper model type that you are using.

  • Menu Language - Language you want the menu for the radio to display in.

  • Build Options - See Build Options for details on the different build options

  • Splash screen: selected splash screen.

  • SD structure path: For radios with SD cards, Taranis and sky9x board, this lets you choose a folder on your hard drive where you have made a copy of what is on the SD card of the radio. This allows OpenTX companion to populate the model image selector with the images that are on the card, and do the same for audio files.

  • Backup Folder: Location of backup eproms

  • Default Stick mode and channel order: These will be applied when creating a new EEPROM document in OpenTX companion.

  • Automatically add version number to firmware files: When downloading a firmware file, its name includes the selected options. If this box is checked, the revision number will be appended to the filename to make it more convenient to maintain files of different versions.

  • Offer to write FW to TX after download.

Example configuration for a Taranis radio

For a Taranis radio, the first thing you would do is select "OpenTX for FrSky Taranis" in the firmware dropdown. Select your firmware language, and the voice language. The top Download button will compile and download the latest available firmware version with the selected language and options. The bottom Download button will open your web browser on a page showing you a selection of voice packs available for the selected language. Set your flight mode and preferred channel order in the dropdowns below, and dismiss the Preferences dialog with OK for now.
