All BEASTX devices 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 a USB2SYS / SPEKTRUM SPMA3030 interface you have to power the device with a separate power supply, i.e. receiver battery or BEC of the helicopter. It will not be powered from the USB interface.<br /> | All BEASTX devices come with a serial communication port which typically is marked with the letters ''SYS''.
