Wireless Trainer Link and the option to add an Advanced Telemetry Display.


  • DESCRIPTION
  • The Linker + adds two unique features to FrSky transmitters; a wireless slave/master trainer function and an advanced telemetry display that also has a GPS based model locator, map displays and a FAI Triangle Feature powered by the iMSB Bluetooth module. 

    What is iMSB you say? 

    iMSB is a Bluetooth data transmission module that sends and logs telemetry data from OpenTx equipped FrSky transmitters to the iMSB app running in iPhone, iPad or iPod touch. The iMSB app is fully user customizable, displaying flight data using a number of thematic veiw screens presented in analogue or digital formats. For more information on the iMSB system click here.

    The Linker+ provides a receptacle to plug the iMSB board into creating a two in one module that can be easily plugged into the JR module port on the back of many FrSky transmitters.

    Let's focus on the trainer function of the Linker+ plus now.

    We saw a need for a wireless trainer feature for the FrSky transmitters.  We worked closely with the OpenTX developers to bring about a workable solution. The linker is fully contained inside the module bay. No loose wires, neat and clean. The design is pretty simple and the second radio can be anything that will bind to the receiver installed in the linker module. 

    Here is the great thing about the Frsky transmitters, thanks to the power of OpenTX, they have one of the most powerful trainer features. This can be used for training, but it can also be used for many other applications. The internal XM+ receiver can pass control of up to 16 channels via the Linker. No other radio system can do that. When might you use this? This can be used for passing off camera controls, advanced items for large scale projects, etc.

    You can actually sub link out to additional FrSky transmitters when they are all equipped with a Linker. Imagine a battleship where each gunner can have control of his own turret with his own radio.

    What you will need

    FrSky Transmitter: Taranis, Taranis Plus, Taranis X9E  or Taranis Q X7. (Does not work with the Horus 10 or 12, or radios using ACCESS.)

    Remote Radio: This can be anything that can use a FrSky DFT, DJT, XJT or DHT module. (see partial list of radios at the bottom of this page.)

    Instructions

    The Linker+ provides a wireless link between two radios, a “Master” radio and a “Remote” radio. The Master radio is the radio that would be under control of the instructor if used in a training session. It should be a Taranis, Taranis Plus/SE, Taranis E (X9E)  or QX7/S and will have the Linker+ module installed in the module bay.

    The “Remote” radio (must be running in D16 mode) is the radio that would be used by a trainee in a training session or as the secondary radio for auxiliary control.

    When used in a training session the Master/Instructor radio will initially be in control of the model. Control will pass to the Remote/Trainee radio when a switch is activated on the Master radio. Typically the Taranis spring-return switch “SH” on the far right will be used so the switch must be held on when you want to give the Remote radio control, releasing the switch will give control back to the Master radio.

    When the Remote radio is used for auxiliary control functions, channels to be controlled by the Remote can be assigned permanently to the Remote radio. An example would be to have the Remote radio assigned to control the camera gimbal on a Multirotor platform.

    Linker+ Setup

    In the Master RADIO SETUP, Page to the TRAINER Screen. In each of the 4 lines Ail, Ele, Rud, Thr: change Mode to “:=” and set the percentage to 100%. Set the Source Channel Number to match the channel number to receive from the Remote radio.

    Select the Model to use in the Master radio. Page to the MODEL SETUP Screen. Set “Trainer Port Mode” to Master/SBUS Module.

    Master Radio Special Function Setup

    In the SPECIAL FUNCTIONS Screen add the line above. When SH is Activated (Moved Toward the Operator) the Remote radio will control the model. When SH is Released the Master radio will control the model.

    To set up channels to be permanently controlled by the Remote radio simply change the switch allocation to the setting “ON”.

    Taranis Remote Radio Setup

    Select the Model to use in the Remote radio

    In the MODEL SETUP Screen: Set “Trainer Port Mode” to Slave/Jack

    Set internal RF mode to D16.

    Bind Remote Radio to Master Linker+ Receiver

    If using a Taranis as the Remote radio, in the Remote radio MODEL SETUP screen, select [Bind]. For Remote radios using a Frsky Module push the bind button. The transmitter should begin to beep or chirp.

    Hold down the bind button in the Linker+ Module with a long pointed object and turn on the Master radio. Wait until the Master radio initializes and the receiver LED’s turn on. Release the Linker receiver bind button. The receiver is now bound to the Remote radio.

    Power cycle both radios.

    Advanced Option - Trainer Quick Take Back

    Our friend Fig Newton on RC Groups was nice enough to point out a really neat option with OpenTX that allows the teacher to regain control of the aircraft simply by moving his sticks, no fumbling for the trainer switch! He has written a blog and included EEPE files for the Taranis radios. Check this link for more details: Click Here. I will warn you that he has some pretty advanced programming going on there, but well worth checking out!


    Some Radio Options for Remote Radio

    With XJT Module Installed

    JR: 347, 388, 783, U8, PCM10, PCM10S, PCM10SX, PCM10IIS, 8103, J9303, MX-22, MX-24S, PX, 9XII   Eurgle: 9X  Turnigy: 9X, 9XR

    The above is a partial listing. Basically any radio with an XJT module that can link to the XM+ receiver will work.

    What's included

    The Linker+ module is pre assembled and ready to use. You will receive a module case with a custom linker+ cover, inside is the Linker+ PC board and pre-installed XM+.

    Optionally, the module will need to be opened to install an iMSB board but no soldering is required.
