Connection scheme
You can use CRSF only for sending control data to you BEASTX device. In this case only connect the TX line of the receiver to the DI1/IO1 port of your BEASTX device.
To enable the telemetry backlink to the radio, connect the RX line of the receiver to the SYS port of your BX device. When the SYS port is already occupied by an SRXL2 device (Spektrum AVIAN ESC) you can alternatively connect the RX line to the DI2 pin (MICROBEAST PLUS / ULTRA only).
In order to use SYS for connecting the BLE2SYS / USBSYS for using the StudioX app, simply disconnect the receiver from SYS temporarily, switch off your radio and power cycle your device. It will then enable "normal" SYS operation for programming purpose.
