   R9MM firmware: FW-R9MM-ACCST_v20190201
   R9M TX module: FW-R9M-ACCST-20190117

2. Insert the R9M TX module and write the firmware you need
   

3. To write the firmware of the R9MM receiver, you need to remove the R9MM receiver, and then write the firmware by connecting to the S.PORT port.
   

4. After both R9M TX and R9MM RX are written into the ACCST firmware.

Binding method:

1. Press and hold the button of RX, power on, the red and green lights are always on.
