This page contains setup instructions for the FrSky Taranis family of transmitters. These include the Trananis X9D, Taranis X9D Plus and Taranis X9E. It may also be relevant to the following transmitters: Turnigy 9XR Pro, Sky board-based, AR9X board-based, 9Xtreme board-based and AR9X Uni board-based.
The instructions below are relevant to the following firmwares:
1. Taranis with erSky9X available [here](http://www.er9x.com)
1. Taranis with OpenTx available [here](http://plaisthos.de/opentx/)
The DIY Multiprotocol module can be used with all transmitters and firmwares in PPM mode. Taranis transmitters running erSky9X or OpenTX (Version 2.1.8 Multi or Version 2.2) fully support Serial mode.
## PPM Mode
Please refer to the [PPM Setup](PPM_Setup.md) page.
##Serial mode
###Enabling Serial Mode
To operate in serial mode, you need one of these firmwares:
- erSky9x Revision 218 or later - the hex files are available [here](http://www.er9x.com) (Mike's latests test versions are available [here](http://openrcforums.com/forum/viewtopic.php?f=7&t=4676)).
Tutorials for uploading new firmware using the SD Card are available [here](http://www.dronetrest.com/t/how-to-upgrade-firmware-for-frsky-taranis-x9d/959) or the CompanionTx or eepe software (recommended) are available [here](http://open-txu.org/home/undergraduate-courses/fund-of-opentx/part-2-flashing-opentx/).
**Note: In these tutorials, substitute the firmwares from the links to the supported firmwares above.**
First, confirm that the DIY Multiprotocol module has the required physical connections between the pins on the back of the Tx and the ATMega328 microprocessor. This may require some soldering and depends on which version of the DIY Multiprotocol module you have. Check out the specific pages for your module hardware (under the section "Enabling Serial") linked [here](Hardware.md) for details.
1. Plug in your DIY Multiprotocol module into the Taranis module bay.
2. If you have a rotary protocol selection switch, turn the switch to position 0 to put the unit into Serial mode.
2. Ensure throttle is down and all switches are in the start position and power up the Taranis. The red LED on the DIY Multiprotocol module should be flashing with a period of about 1s indicating that it has not established a valid serial link with the Tx. This is expected as we have not set up the Tx yet.
3. Create a new model (make sure channel order is AETR) and on the first Model Settings page scroll down to disable the internal RF and enable the external RF by selecting MULTI as the external RF. Your Taranis settings should look like this: {insert picture of Taranis screen showing external RF settings} The Red LED on the DIY Multiprotocol module should briefly flash and then go off. This confirms that the DIY Multiprotocol module has established serial communication with the Tx.
4. If the red LED on the module continues to flash at a period of about 1s then it signals that serial communication has not been established. Check your settings under the model menu as described above and check that the protocol selection switch on the module is at 0 (zero). If there is still no communication, power down and power up the Tx. Finally check that you have correctly enabled your module for serial as described in specific pages for your module hardware (under the section "Enabling Serial") linked [here](Hardware.md)
To select the protocol, scroll through the available options under the Model Settings menu. Depending on which protocol you have selected you may be required to select a sup-protocol and options. For example, the FrSky protocol has three sub-protocols FrSkyV, FrSkyD and FrSkyX. Each of the sub-protocols may have options that specify the number of channels and the packet frame rate, etc.
The following picture shows DSM – DSMX – Option 6 (6 channels and 11ms frame rate). Check out the [Protocol Details](Protocol_Details.md) page for detailed information and suggestions regarding the sub-protocols and options.
###Binding in Serial mode
1. Switch on the model or put the receiver into bind mode
1. On the transmitter go to the Model Settings menu and scroll down to the [Bind] menu option and press Enter.
1. Press Enter again to exit Bind mode
For many consumer models consider checking the Autobind option. This will initiate the bind sequence as soon as the module is powered up by the transmitter.
If you are struggling to get a bind please see the [Getting the bind timing right page](Bind_Timing.md)
