The P²-JR Header is an adapter from a P²-BUS cable terminating in a MPX plug to four UNI

servo leads. A typical use for the adapter is in a wing, where up to four Servos or the P²-Bridge can be connected.

The SparkSwitch RS is a compact, high-performance ignition switch featuring rotational speed (RPM) monitoring and optional voltage regulation for 6V ignition systems. The SparkSwitch RS enables the user to switch the ignition on and off conveniently from the transmitter. The switched state can be checked at any time using the external LED or a telemetry status message. These features of the SparkSwitch RS enhance operating safety as well as simplifying the handling of petrol engines. In an emergency - such as the failure of a throttle servo - the SparkSwitch RS can be used to stop the engine quickly.

An important feature is galvanic separation between the receiving system and the ignition system. The switching process as well as RPM feedback from the ignition unit are optically isolated from the receiver. This ensures that a fault in the ignition system shielding, or any other defect, cannot cause interference to the sensitive receiving system.

The RPM (rotational speed) monitor input can be connected directly to the Tacho output of the ignition unit - if present. If your ignition system does not include a Tacho socket, we can supply a separate sensor RPM-Probe which can be connected in parallel with the Hall sensor. The RPM data can be transferred to any of the current telemetry systems: the SparkSwitch RS automatically detects the system in use, eliminating the need for adjustments using the USB interface.

The SparkSwitch RS can be supplied in either of two variants: with or without voltage regulation. The regulated variant reliably reduces the input voltage (max. 9.0V) to 6.0V. The version without voltage regulation passes the full voltage (max. 13.0V) through

The RPM probe is connected directly to the ignition unit's induction sensor or magnet sensor. The unit amplifies and processes the signal in such a way that the output passes accurate rotational speed pulses to the SparkSwitch RS, which in turn makes the rotational speed (rpm) available for the radio control system's telemetry system.

The connecting lead is simply plugged in between the ignition unit and the induction or Hall sensor. DA engines, in particular, utilise an induction pick-up, and this system collects the signal and amplifies it without placing a load on the signals.

The RPM probe draws power from the SparkSwitch RS.

Universal servo bus adapter with electronic fuse

The P²-ServoBridge is the key component in an entirely new servo bus technology which presents unprecedented possibilities. If a servo bus is employed, only one cable is required for several servos. The servos are individually addressed, and therefore each servo knows which signal is intended for it. Earlier servo bus systems simplified the wiring in the model; for example, saving multiple plug / socket connections in the wings. The new feature of the PowerBox P²-Bus is that it works bi-directionally! This means: not only can accurate digital signals be fed to the servos, but important telemetry data - such as current, voltage, temperature and other information - can also be fed back to the Core or Atom transmitter. Targeted alarm settings at the transmitter alert the user to defects in good time, so they can be corrected without the need to analyse reams of data. But even that's not all: the parameters of the P²-ServoBridge can be altered directly from the transmitter. The integral electronic fuse can be adjusted to suit the particular servo, precisely to the milli-second and milli-amp. A micro-controller decodes the bus signal, monitors the current accurately and at high speed at the servo itself, and switches the servo off reliably if the set thresholds are exceeded.

This technology eliminates all the disadvantages inherent in simple resettable fuses (polyfuses) - such as temperature dependence or ageing effects. A range of pre-set profiles enables any modeller to find the correct setting for a particular servo even without a knowledge of electronics.

The adhesive pad supplied is used to attach the P²-Servobridge to the bottom or side of the servo case, where it also monitors the servo temperature. In addition to the P²-BUS, the P²-Servobridge works with other bus systems such as S.BUS or SRXL, and even with conventional PWM servo signals. This means that the device can also be used for accurate over-voltage power-off - for example, with retract servos - even when bus wiring is not used. The input signal is detected automatically, and the fuse is pre-set to suit standard servos with an output torque of up to 30kg/cm, so in most applications the P²-Servobridge can be used as a Plug ´n Play device.

The PowerBox MicroMatch is the ideal solution for models where there is no space for a PowerBox, or where the PowerBox in use does not include the MicroMatch’sfunctions.
The MicroMatch provides a very simple method of fine-tuning the servo travels and centre positions of both outputs. Its main application is for systems where two servos operate a single control surface; the unit can match them electronically to run exactly in parallel. This prevents the servos counteracting each other, and allows the torque and speed of both servos to be exploited to the full. A further positive effect is a significant reduction in current drain and servo wear.

The MicroMatch includes a servo reverse function which changes the direction of rotation of the servos with a single click. This is ideal for elevator servos which are installed as a mirror-image pair, allowing them to be operated using just one channel. Further applications are twin rudders or steerable nosewheels.
All adjustments can be carried out using the USB interface (Jeti and MPX adapters can also be used) or a BlueCom adapter. The BlueCom option offers one very practical feature: it is possible to make direct adjustments at the servo output arm, and alter the settings conveniently using a mobile phone and a Bluetooth link!
The MicroMatch includes an update facility, allowing for possible future expansions to the range of functions.

Features

If your PowerBox system is capable of receiving Firmware updates, this is the cable you need to transfer the update.

The signal amplifier is ideal for use in any model where reliable servo control is inhibited by long cables. Many 2.4 GHz receivers generate low signal levels, and in this case the signal amplifier ensures smooth, more accurate servo response.

This in turn reduces current drain, and increases the effective life of your servos. The signal amplifier is simply and directly looped into the servo lead, and increases the signal level to a value suitable for any servo.

The Magic Jeti Switch makes it possible to switch any PowerBox on and off from the transmitter. It forms the ideal complement to any PowerBox system which is installed in an inaccessible location, or in a model where an external switch is not desirable.

The Magic Jeti Switch is stuck to the Jeti RCSW and connected to it, producing a compact, wireless switching unit which takes the switching signal from the Jeti RC-Switch and “translates” it for the PowerBox. At the transmitter the switching process can be triggered using any switch, and confirmed on-screen with a button. This procedure eliminates the possibility of switching the model off accidentally. You can also set audible confirmation for the switching process by means of an audio file (download in our forum).

The combination of Jeti RCSW and Magic Jeti Switch draws a very low idle current (< 200 µA), but nevertheless we recommend that you disconnect the switch from thePowerBox if flying is unlikely for a protracted period, e.g. over the Winter.

The Magic Jeti Switch is available in two versions: one is fitted with a red plug, and is suitable for the BaseLog, Evolution, Competition and Cockpit; the other with a black plug, suitable for the Royal SRS and Champion SRS.

The MagSensor represents an alternative method of operating and switching our PowerBox battery backers. The circuit is based on modern extremely sensetive, zero-contact "Hall sensors", which respond to a defined magnetic field by activating the electronic switches in the PowerBox. The Hall sensors do not switch the cur-rent, but simply pass on the switching signal.

The PowerBus Splitter is required if the PowerBox does not feature a sufficient number of outputs. For example, if you wish to use the bus technology for both wings as well as elevator and rudder, you will need a total of three bus leads.

The PowerBus to BUS Adapter is designed for use with servos which are fitted with an integral bus decoder. At present these are Futaba S-Bus servos. When these servos are used, the channel assignment is programmed directly at the servo. The PowerBus to Bus Adapter does not feature a decoder, but nevertheless all the outputs are protected against short-circuits both in the signal wire and the power supply wires, as you would expect. The adapter includes integral signal amplifiers for all servo outputs as well as the adapter’s PowerBus output. This means that as many bus adapters as required can be connected in series, i.e. cascaded
