#Protocols details Here are detailed descriptions of every supported protocols (sorted by RF modules) as well as the available options for each protocol.
If you want to see a list of models that use these protocols see the Models page.
The Deviation project (on which this project was based) have a useful list of models and protocols here.
Default Mapping of Protocols
Here is the default mapping of protocols to the 16-position protocol selection switch on the module. You can customize these when you compile your own firmware as described in Compiling and Programming.
Note that the protocol must be selected before the unit is turned on.

Useful notes and definitions
- Extended limits supported - A command range of -125%..+125% will be transmitted. Otherwise the default is -100%..+100% only.
- Channel Order - The channel order assumed in all the documentation is AETR and it is highly recommended that you keep it this way. You can change this in the compilation settings. However, please indicate your channel order in all questions and posts on the forum pages.
- Autobind protocol:
- The transmitter will automatically initiate a bind sequence on power up. This is for models where the receiver expects to rebind every time it is powered up. In these protocols you do not need to press the bind button at power up to bind, it will be done automatically.
- Enable Bind from channel feature:
- Bind from channel can be globally enabled/disabled in _config.h using ENABLE_BIND_CH.
- Bind from channel can be locally enabled/disabled by setting Autobind to Y/N per model for serial or per dial switch number for ppm.
- Bind channel can be choosen on any channel between 5 and 16 using BIND_CH in _config.h.
- Bind will only happen if all these elements are happening at the same time:
- Autobind = Y
- Throttle = LOW (<-95%)
- Bind channel is going from -100% to +100%
- Additional notes:
- It's recommended to combine Throttle cut with another button to drive the bind channel. This will prevent to launch a bind while flying...
- Bind channel does not have to be assigned to a free channel. Since it only acts when Throttle is Low (and throttle cut active), it could be used on the same channel as Flip for example since you are not going to flip your model when Throttle is low... Same goes for RTH and such other features.
- Using channel 16 for the bind channel seems the most relevant as only one protocol so far is using 16 channels which is FrSkyX. But even on FrSkyX this feature won't have any impact since there is NO valid reason to have Autobind set to Y for such a protocol.

Option is used to change the servo refresh rate. A value of 0 gives 50Hz (min), 70 gives 400Hz (max). Specific refresh rate value can be calculated like this option=(refresh_rate-50)/5.
RX_Num is used to give a number a given RX. You must use a different RX_Num per RX. A maximum of 16 AFHDS2A RXs are supported.

Note that the RX ouput will be EATR.
Bind procedure using serial:
- With the TX off, put the binding plug in and power on the RX (RX LED slow blink), then power it down and remove the binding plug. Receiver should now be in autobind mode.
- Turn on the TX, set protocol = Devo with option=0, turn off the TX (TX is now in autobind mode).
- Turn on RX (RX LED fast blink).
- Turn on TX (RX LED solid, TX LED fast blink).
- Wait for bind on the TX to complete (TX LED solid).
- Make sure to set the RX_Num value for model match.
- Change option to 1 to use the global ID.
- Do not touch option/RX_Num anymore.
Bind procedure using PPM:
- With the TX off, put the binding plug in and power on the RX (RX LED slow blink), then power it down and remove the binding plug. Receiver should now be in autobind mode.
- Turn on RX (RX LED fast blink).
- Turn the dial to the model number running protocol DEVO on the module.
- Press the bind button and turn on the TX. TX is now in autobind mode.
- Release bind button after 1 second: RX LED solid, TX LED fast blink.
- Wait for bind on the TX to complete (TX LED solid).
- Press the bind button for 1 second. TX/RX is now in fixed ID mode.
- To verify that the TX is in fixed mode: power cycle the TX, the module LED should be solid ON (no blink).
- Note: Autobind/fixed ID mode is linked to the dial number. Which means that you can have multiple dial numbers set to the same protocol DEVO with different RX_Num and have different bind modes at the same time. It enables PPM users to get model match under DEVO.
##DSM Extended limits supported
Telemetry enabled for TSSI and plugins
option=number of channels from 4 to 12. An invalid option value will end up with 6 channels.

|---|---|---|---|---|---|---|---|---|---|---|---|
| A | E | T | R | CH5 | CH6 | CH7 | CH8 | CH9 | CH10 | CH11 | CH12 |
Notes:
- model/type/number of channels indicated on the RX can be different from what the RX is in fact wanting to see. So don't hesitate to test different combinations until you have something working. Using Auto is the best way to find these settings.
- RX ouput will always be TAER independently of the input AETR, RETA...
###Sub_protocol DSM2_22 DSM2, Resolution 1024, refresh rate 22ms ###Sub_protocol DSM2_11 DSM2, Resolution 2048, refresh rate 11ms ###Sub_protocol DSMX_22 DSMX, Resolution 2048, refresh rate 22ms ###Sub_protocol DSMX_11 DSMX, Resolution 2048, refresh rate 11ms ###Sub_protocol AUTO The "AUTO" feature enables the TX to automatically choose what are the best settings for your DSM RX and update your model protocol settings accordingly.
The current radio firmware which are able to use the "AUTO" feature are ersky9x (9XR Pro, 9Xtreme, Taranis, ...) and er9x for M128 (9XR) and M2561. For these firmwares, you must have a telemetry enabled TX and you have to make sure you set the Telemetry "Usr proto" to "DSMx". Also on er9x you will need to be sure to match the polarity of the telemetry serial (normal or inverted by bitbashing), while on ersky9x you can set "Invert COM1" accordinlgy.

Note: RX ouput will always be AETR independently of the input AETR, RETA...
###WK2801 This roughly corresponds to the number of channels supported, but many of the newer 6-channel receivers actually support the WK2801 protocol. It is recommended to try the WK2801 protocol 1st when working with older Walkera models before attempting the WK2601 or WK2401 mode, as the WK2801 is a superior protocol. The WK2801 protocol supports up to 8 channels.

###W6_HEL and W6HEL_I WK2601 Heli: AIL, ELE, THR, RUD, GYRO are proportional. Gear (ch 5) is binary. COL (ch 6) is linked to Thr. If Ch6 >= 0, the receiver will apply a 3D curve to the Thr. If Ch6 < 0, the receiver will apply normal curves to the Thr. The value of Ch6 defines the ratio of COL to THR.
W6HEL_I: Invert COL servo
