{{WARNING_QUOTE|'''Never connect the 4-pin receiver connector to MICROBEAST ULTRA without modification and in wrong polarity! This will damage your receiver immediately!''' Check polarity at least twice before connecting the receiver to MICROBEAST ULTRA . It is up to you to make sure polarity is correct. We do not assume any liability in case you do it wrong.}}<br />

Note that it is not possible to use the [SYS] port for communication with the StudioX app when the telemetry data wire is connected. Still you can access StudioX and configure your helicopter by app if you connect the USB2SYS/BLE2SYS interface to the [SYS] port before powering up the helicopter.<br />

When using a telemetry receiver and an ESC with telemetry data connector, the ESC is connected to the '''[IO1]''' output. The telemetry data signal of the ESC is connected to '''[IO2]''' input. (You will get further information about connecting the speed controller in a later section!)<br />

You can connect a power supply (second BEC wire, battery) to the [SYS] port and/or to the receiver (in case this has additional servo or battery ports). All servo ports will form a parallel power circuit (except the port [RUD|PIT|AUX]; please do not connect anything here!).<br />

{{WARNING_QUOTE|'''When using a big heli with standard size servos it may be insufficient to only provide power at the [SYS] port or receiver.''' Adding additional power wires is highly recommended! If there are no other ports left to additionally feed in power, we recommend using the MICROBEAST PLUS HD which comes witch an additional high power input. This reduces wiring resistance and serves todays demands for a robust servo power supply.}}<br />

<br />

When using a Graupner HOTT receiver with telemetry uplink, the throttle servo or ESC is connected to the '''[IO2]''' output. The telemetry data signal of the ESC is connected at the side input of MICROBEAST ULTRA. Here "-" (minus)  is the second pin from front and "S" (signal) is the third pin from front. "+" (plus) can be connected at the first pin from behind.<br />
