FrSky R9 MX OTA Receiver
Introduction
The R9 MX is the enhanced versions of the previous R9 MM/Mini series long-range capable receivers, equivalent in size and weight equipped with a robust detachable Ipex1 antenna connector.
The R9 MX takes features from the previous R9 Mini and R9 MM making it compatible with more external devices by providing an Inverted S. Port output and supporting the redundancy function. Additionally, it retains soldering points to connect 4 PWM channels. The enhanced design proves to be more durable, and in conjunction with the latest ACCESS firmware, the two are now synchronized and we are able to unlock the true potential of the ACCESS protocol.

- The transmitter exit [Bind], GREEN LED will flash, RED LED will be off, indicating working normally
About OTA function
— For Taranis X-Lite Pro as an example, go to the SD CARD 2/7, and select the FW, press the enter button, select [Flash receiver by ext. OTA], power on the receiver, select the RX, go to the [ENTER], complete the flash process, the transmitter will display [Flash successful]. Re-power the receiver and wait for 3 seconds, the Green LED starts flashing indicates the receiver works properly at the moment.
Note: Update the firmware after the receiver gets binded.
How to enable/disable the receiver telemetry

How to switch the F.Port
— For Taranis X-Lite Pro as an example, select the Receiver, press the ENTER button, select the Options, and select F.Port.
How to Set Failsafe mode (on the transmitter)
There are 3 failsafe modes: No Pulse, Hold, Custom
- No Pulse: on loss of signal the receiver produces no pulses on any channel. To use this type, select it in the menu and wait 9 seconds for the failsafe to take effect.
- Hold: the model will maintain the last position after the signal is lost. To use this type, select it in the menu and wait 9 seconds for the failsafe to take effect.
- Custom: the customized position of each individual channel. The model will move to the pre-set position after the signal is lost. Move the cursor to “Set” and press ENTER, you will see FAILSAFE SETTING screen below. Move the cursor to the channel you want to set failsafe on, and press ENTER. When moving the corresponding sticks or switches, you will see the channel bar moving. Move the channel bar to the place you want for failsafe and long press ENTER to finish the setting. Wait 9 seconds before the failsafe takes effect.
Note: If failsafe is not set, the model will hold the last position after signal is lost, thus it may fly away or cause injury.
