Connection to BEASTX device

All BEASTX gyros come with a serial communication port which typically is marked with the letters SYS. Connect the servo wire coming from your USB interface to this port. Make sure to connect the wire in correct polarity on both sides!

When using the USB2SYS interface you have to power the device with a separate power supply, i.e. receiver battery or BEC of the R/C model. It will not be powered from the USB port.	Connecting the BLE2SYS is similar. Just plug it into [SYS] port and you're good to go.

Also you can use a RX2SIM Wireless Multi-Sim Adapter instead of the USB2SYS interface. For this you can switch the RX2SIM into an USB2SYS emulation mode (push button on the RX2SIM several times until the LED lights up in orange color).

In this configuration the BEASTX gyro will be powered from the USB port. Anyhow, this only will work when receiver and servos are not connected to the gyro! Otherwise the power of the USB port will not be sufficient to supply all consumers. In this case you have to power the device from the receiver battery as well.	But here when using more than 6 Volts (i. e. using a 2s Lipo battery as receiver power supply) you must disconnect the red wire (plus pole) from the servo wire going to the interface. Otherwise you will damage the RX2SIM and/or USB port of your computer!

Since BEASTX firmware version 5.9.x, it is possible to connect a telemetry receiver to the [SYS] port to transfer telemetry data and menu settings to and from the BEASTX device (EXBUS/SBUS2/F.Port). In order to connect the interface for the StudioX app, you can temporarily remove the receiver and connect the SYS interface to the [SYS] port. However, in this case, it may not be possible to control the system from the radio in the StudioX menus! As a workaround, connect the USB2SYS/BLE2SYS interface to the side of your MICROBEAST PLUS/MICROBEAST ULTRA instead of using the [SYS] port. This will require an adapter from the standard servo connector to the JST 6-pin format. Using EXBUS telemetry with NANOBEAST you can connect the EXBUS receiver to the DI port temporarily, so you can connect your interface to SYS port and will be able to use radio control for the setup. Using a CRSF receiver simply disconnect the TX line from SYS port and make sure the radio transmitter is OFF before powering up your BEASTX device. Then after 5 seconds power ON your transmitter. In this case the telemetry will be disabled on SYS port and you can connect your interface for configuration with StudioX Flow app while still be able to control the helicopter with the radio.

Connection to StudioX Flow app

On a Windows or mac computer you can connect either per USB or Bluetooth. With smartphone/tablet only Bluetooth can be used. Click the USB or BLE symbol to initiate connection to your BEASTX device. In the following you'll see a list of ports/interfaces that have been found. Choose the port name that belongs to your interface.

The USB2SYS is usually named /dev/tty.usbserial-0001 or /dev/tty.SLAB_USBtoUART on macOS computers. On Windows systems it'll be named COMxy. If you can't find out which port name your device has, simply disconnect the USB once and click the background to abort connection. Click "Scan USB" button again and check out the names on the device list. Click the background again, reconnect USB2SYS and click "Scan USB" button again. Now choose the item, that was not there before.

With the BLE2SYS the device in the list usually is named "BLE2SYS" unless the name wasn't changed by the user. Here the scan process usually takes around 5 seconds. If the scan process finishes immediately and the box stays empty it is very likely the bluetooth function is switched off on your phone/computer or the app has no rights to access the bluetooth connection! So check system settings of your device in this case.

In case you are asked for the BLE2SYS pin code, this usually is 1111. If that doesn't work, please try 0000 or 1234.

Please note that it's possible to speed up connection sequence once you've determined the interface name. Go to "Settings" and enable the "Autoconnect" button. When using StudioX Flow later onwards, it'll automatically recognize the listed device names and will connect with these if they're present.
