Zur Ansteuerung des MICROBEAST PLUS kann eine Vielzahl unterschiedlicher Empfänger­typen verwendet werden. Nachfolgend werden sämtliche Anschlussmöglichkeiten und Arten von Empfängern gezeigt. Achte grundsätzlich immer darauf, dass die Stecker fest eingesteckt sind. Die Stiftleiste von MICROBEAST PLUS ist so ausgelegt, dass sich die Stecker gegenseitig aneinanderdrücken und so gegen selbstständiges Lösen gesichert sind. Prüfen aber dennoch, ob ein fester Sitz gegeben ist. Insbesondere bei der Verwendung von SingleLine-Empfängern ist dies oftmals nicht gegeben, da Stecker ohne direkte Nachbarn eingesteckt sein könnten. Solche Stecker sollten immer zusätzlich gegen unbeabsichtigtes Lösen gesichert werden, vor allem auch auf der Empfängerseite!

Standard receiver

A conventional receiver with multiple servo output connectors is what we consider a "Standard receiver". Here you connect each output to one control function of MICROBEAST PLUS by using one connection wire for each function. The 5 control functions (wires) are: Aileron, Elevator, Rudder, Collective pitch and Gyro gain. Connect each wire to the corresponding servo output at the receiver which you like to use for the specific function. If you don't know which stick controls which channel have a look at your radio's servo monitor, refer to your radios instruction manual or simply connect a servo to each channel testwise!

Here we show connection layouts for two common radio brands. Note that this is only exemplary, the channel output of your transmitter can by different even when using a radio of this brand. And you can use any radio system on the market, not only these two brands!

• The wires for rudder, pitch and gyro are signal wires. They must be placed on the same receiver side as the the both orange wires from aileron and elevator!
• You must connect all 5 functions/wires to the receiver. When you don't connect all wires, the system will not finish initialization sequence!
• The throttle servo/speed controller is connected to the receiver's throttle output. Using the headspeed governor function of MICROBEAST PLUS is not possible in combination with a Standard receiver!

Receivers with single wire output (single-line receivers)

A single-line receiver transmits all channels (control functions) by one single connection wire to MICROBEAST PLUS. This is done by packing all channel output data to a digital data paket or by chaining the servo signals. At the moment MICROBEAST PLUS supports the following systems: Multiplex® SRLX, Spektrum® SRXL, Futaba® SBus, JR® X-Bus(B), Jeti® UDI, Jeti® EXBus, ALIGN® iBus, FlySky® iBus, Graupner HOTT® SUMD, SPPM

There are single-line receivers available that supply additional servo outputs. In combination with MICROBEAST PLUS you only have to treat such receivers as single-line receivers if you really use the single-line function. If you connect the receiver by using the standard 5-wire layout as shown above, such receiver has to be considered as "Standard receiver".

• The single-line connection wire is plugged into the [DI1] input of MICROBEAST PLUS
• The throttle servo or ESC is connected to the [CH5] output. When using a speed controller with BEC, from here the power will be distributed to receiver and servos.
• Alternatively or additionally you can connect a power supply/second BEC wire/buffering 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.

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.

Remote satellite (Spektrum® DSM/JR® DMSS/ALIGN® iBus)

A special type of single-line receiver is the remote satellite. These receivers usually serve as additional receiving unit in combination with a (bigger) main receiver to provide a more robust and fail safe radio system. With MICROBEAST PLUS you can use such receivers as stand alone receiving unit to achieve a small and light weight radio system for small sized rc models. MICROBEAST PLUS supports the following systems: Spektrum® DSM2, Spektrum® DSMX, JR® DMSS and ALIGN® iBus. The remote receiver can be directly connected to the white pin board at the side of MICROBEAST PLUS. Here the receiver will be powered with a stabilized voltage of 3.3 Volts. Alternatively if you own the optional available Spektrum® satellite adapter (Order Nr. BXA76009) you can connect the receiver at the front pin board to the [DI1] digital input, just like most other single-wire receivers. This allows to keep the white pin board free for connecting a sensor.

Please note: MICROBEAST PLUS does not support connecting more than one remote satellite at a time!

When using a speed controller with BEC, the power will be distributed from [CH5] input to receiver and servos. Alternatively or additionally you can connect a power supply/second BEC wire/buffering battery to the [SYS] port.

Using a remote satellite is only recommended for small rc modells like helicopters of 450 size or smaller. Due to the design, one single receiving unit is more prone to radio interference and can result in reduced transmission range.

Spektrum® SRXL2 receiver

Spektrum SRXL2 receivers are available in different forms. There exist receivers with standard servo connectors as well as remote satellites with a special 4-wire connector. The output signal of any of those receiver must be connected to the pin board at the side of MICROBEAST PLUS.
Please note: MICROBEAST PLUS does not support connecting more than one SRXL2 receiver at a time!

When using a speed controller with BEC, the power will be distributed from [CH5] input of MICROBEAST PLUS to the receiver. Alternatively or additionally you can connect a power supply/second BEC wire/buffering battery to the [SYS] port. It is not recommended to connect power to the receiver directly!

In order to connect a receiver with standard servo connectors, i.e. the AR6610T, you need the SRXL2 receiver adapter. Also you may use the governor sensor adapter BXA76401 but this requires to modify the wiring layout as shown below!

SRXL2 receiver with standard servo connector and adapter

In order to connect a SRXL2 remote satellite like SPM4650 it is necessary to interchange the plus and minus wires (usually black&orange) of the 4-wire receiver connector. In this configuration you can directly plug in the receiver without the need for an extra adapter.

SRXL2 satellite receiver with modified satellite connector

Never connect the 4-wire receiver connector to MICROBEAST PLUS in wrong polarity! This will damage your receiver immediately! Check polarity at least twice before connecting the receiver to MICROBEAST PLUS. It is up to you to make sure polarity is correct. We do not assume any liability in case you do it wrong.
