Introduction
Dear PowerBox customer, we are pleased you chose the PowerBox Receiver PBR-14D and the PowerBox remote control system. This represents the most advanced and sophisticated transmission and reception system for your valuable models in the model building sector. Unprecedented ranges in the 2.4GHz band and fast, precise data transmission in both directions characterize this radio link!
1. Product Description
The PowerBox receivers, based on their technical specifications, are not merely "receivers" but "transceivers". They can send and receive with the same data rate and range as the associated remote control. All PowerBox receivers fundamentally include a preamplifier alongside the radio chip, which, in conjunction with other technical refinements, enables the high range. The PowerBox radio transmission is a hopping system that utilizes at least 66 out of 198 possible channels. An intelligent hopping sequence ensures interference-free operation even when the frequency band is heavily occupied.
The suffix D, S/XS, or SL indicates the number of radio units built into the receiver. For the D types, PBR-9D, PBR-14D, and PBR-26D, two entirely independent receiving and transmitting units are installed.
Compared to systems that switch between two antennas on a 50-50 basis, this design offers the advantage that if reception is lost on one antenna, not 50% of the information is fundamentally lost. Furthermore, the incoming signal is not dampened by switching diodes, which would be particularly detrimental to the radio chip.
With PowerBox receivers, both receiving units receive the data packet undamped and evaluate it completely. If one of the two packets is faulty, the signal strength is poor, or it is missing entirely, the packet from the other receiving unit is used and forwarded to the servo or digital outputs. The result is a 100% signal even with complete shadowing of one antenna.
For types PBR7S, PBR9D, PBR10SL, and PBR-14D, an additional receiving unit, such as the PBR26XS, can be connected via the FastTrack connection. Should the main receiver fail to receive data from its built-in antennas, the data from the "satellite receiver" bridges this gap seamlessly.
Another important feature is the integrated iGyro System. The receivers PBR-7S, PBR-9D, PBR-10SL, PBR-26D, and PBR-14D already have the iGyro software built-in for controlling 6 separate axes. To use the iGyro, simply plug an iGyro SAT into the FastTrack connection. If the integrated iGyro detects a GPSIII or a PBS-TAV sensor on the P2-BUS, the gyro sensitivity is even compensated for speed!
All iGyro settings are conveniently managed from the transmitter via the Telemetry Menu.

All PBR receivers can output various BUS signals via the FastTrack output to be compatible with 3rd Party products, such as Heli-Gyros. Besides S.BUS and SRXL, an analog PPM signal can also be output.
A unique feature on the market is the ability to update the receivers from the transmitter. You no longer need to remove the receiver(s) from the model or connect a laptop and USB interface to update the receiver software.
3. Power Supply
The PBR-14D is powered via the MPX High Current Connector. With the integrated electronic switch, no further external components are necessary. The PBR-14D can be switched on and off using the built-in blue button, a separately available MicroSwitch (#3584), or MicroMag (#3585).
To switch, press the button for approximately 2 seconds, release briefly, and press again to confirm the switching operation. If you use the internal button, the switching operation is not visually indicated; you only see the switching status on the LED that indicates reception status. If you use the external MicroSwitch or the MicroMag magnetic switch, you will also see the switching status on the LED built into the switch.
4. Binding
All receivers can be bound in two ways:
- Connect the receiver first: The LED will blink rapidly for approximately 10 seconds. Press "Bind" on the transmitter. The transmitter and receiver will bind. If you wait longer than 10 seconds, the receiver's LED will switch to a slower blinking pattern. Binding cannot occur again until the power supply is interrupted.
- Press "Bind" on the transmitter first: Then connect the receiver to a power source. The transmitter and receiver will bind.
5. Detailed Description of Connections
a) PWM Outputs
The PWM outputs are not only numbered 1-XX but also designated A-I. The receiver outputs can optionally output other channel numbers. For example, with the PBR-9D, channels 10-19 can be output instead of outputs 1-9.
b) P2-BUS
This interface is for external, super-fast P2-BUS telemetry and digital servo output. All connected sensors are scanned upon power-up and displayed in the transmitter. The P2-BUS connection is also used for updating receivers with the USB Interface Adapter.
c) FastTrack / Data
This connection can be configured for various functions from the transmitter. You can set it for FastTrack, P2BusOUT, S.BUS, SRXL-16, PPM12, or another servo output.
- FastTrack: The iGyro SAT or an additional satellite receiver (PBR-26XS) can be connected here. FastTrack is a fast real-time BUS system. The iGyro SAT and the optional satellite receiver are connected simultaneously via a Y-cable. With the iGyro SAT connected, you get a 6-axis iGyro system that is fully adjustable from the transmitter.
- P2BusOUT: This option is used to wirelessly supply ground stations, such as those used in Triangle flying, with telemetry data from the model. The receiver "listens" to the radio traffic between the transmitter and receiver in the model and forwards the telemetry information from the model to the connected ground station.
- PWM: If you select this option, you can connect an additional servo to FastTrack/Data. The output channel depends on the receiver used. For the PBR-14D, channel 15 is output here, for example.
- S.BUS and SRXL-16: These digital BUS signals can be processed by many gyro and battery distributors and thus serve as a universal interface for 3rd party accessories, such as Heligyros.
- PPM12: From Version 3.5, all receivers also have the option to output an analog PPM12 signal. A practical application is the wireless connection to PC flight simulators.
6. Meaning of the LED
The built-in LED can indicate various statuses:
- Solid Blue Light: The receiver has a connection to the transmitter and sufficient signal strength.
- Fast Blue Blinking: The receiver is waiting for a bind signal.
- Slow Red Blinking: The receiver has no signal.
- Solid Red Light: An update has failed; the receiver is in bootloader mode. Restart the update using the Rescue-Mode.
7. Installation and Antenna Placement
All PowerBox receiver boards are built using SMD technology, making them extremely resistant to vibration and shock. The PBR-14D is ideally attached using the supplied mounting plate. It can also be attached to a firm surface using double-sided adhesive tape.
Optimal antenna placement is highly dependent on the model, fuselage material, and installation location. We generally recommend routing the antennas out of the fuselage. This ensures the best reception, regardless of the model's material.
8. Other Settings
The receivers have several other setting options, which can be adjusted from the transmitter via the Telemetry Menu:
- Framerate: Defines the repetition frequency of the servo impulses. By default, this setting is 18ms. Modern digital servos can operate more precisely and smoothly with 12ms.
- Output A Start: Shift of the start channel. This allows you to "cascade" receivers. For example, you can have a PBR-9D output channels 1-9 and another PBR-7S for channels 9-16.
- Hold/Failsafe: This setting is not configured in the receiver but in the transmitter's function menu.
- iGyro: A detailed description of the iGyro features can be found in the manual for the iGyro SAT. The iGyro function in the PowerBox receivers is completely identical to the iGyro function in our larger PowerBox Systems or the iGyro3xtra.
9. Operating Notes
All PowerBox receivers transmit battery voltage and reception quality by default. The following values are transmitted:
- Battery Voltage: Shows the battery voltage present at the servo sockets. Note: For regulated battery distributors, this displays the regulated voltage, not the battery voltage.
- RSSI: This value indicates the antenna input level. It is given in dBm – a logarithmic power value.
- LQI: This value shows the reception quality in percent. The value is calculated in the receiver from the number of lost data packets of an antenna and the power level over time. Use this value to determine if the installation position of the individual antennas is well chosen.
The LQI is a very informative measurement of the radio link quality. For optimal monitoring, create a widget with the LQI value on the telemetry screen. Set an alarm threshold between 60% and 70%. This will immediately notify you of a reception problem via an alarm.
From Version 3.5, an additional LQI value is available, which calculates the LQI value across both antennas. Only data packets lost simultaneously by both antennas are used for this evaluation.
- Status: Status messages are displayed here, for example, the status of a connected iGyro SAT or GPSIII.
