2PowerBox-Systems − World Leaders in RC Power Supply Systems
Dear PowerBox customer,
We are delighted that you have decided to purchase a PBR-14D transceiver,
which almost certainly represents the most highly developed and most advanced
transmitting and receiving system for your valuable models available anywhere
in the modelling world. Unprecedented range in the 2.4 GHz band, and ultra-fast,
ultra-precise data transfer in both directions - these are the outstanding features
of this radio system.
1. PRODUCT DESCRIPTION
If you study the specications closely, it is clear that PowerBox receivers are by
no means “receivers” in the usual sense; they are “transceivers”. They are capable
of transmitting and receiving at the same data rate and the same range as the
associated system transmitter.
All PowerBox transceivers feature a radio chip, but an essential difference is
the integral pre-amplier, which is one of the factors which make the system’s
extremely long range possible. The PowerBox radio link is a hopping system
which uses at least 66 of 198 possible channels. An intelligent hopping sequence
is employed, ensuring interference-free operation even when the frequency band
is heavily used.
The sux D, S/XS or SL indicates the number of radio units installed in the
transceiver. The D types PBR-9D and PBR-26D incorporate two fully independent
receive / transmit units.
Other systems feature two aerials, switching between them 50-50, but if one ae-
rial loses the signal, 50% of the information is inevitably lost; our design does not

suffer that drawback. There are also no switching diodes which have a damping
effect on the signal as it arrives; this has a particularly adverse effect on the radio
chip.
In contrast, both the receive units in PowerBox transceivers pick up the data
packet in undamped form, and subject it to a full analysis. If one of the two pa-
ckets contain errors, or if the signal strength is poor, or if the signal is completely
absent, the data packet picked up by the other receive unit is used, and passed to
the servo outputs or digital outputs. The result is a 100% signal even if one aerial
is completely blocked.
As of software version 3.5 it is possible to connect a supplementary receiving
unit, such as the PBR-26XS, to the FastTrack socket of receiver types PBR7S,
PBR9D and PBR10SL. If the primary receiver should receive no data from its inte-
gral aerials, the gap is lled seamlessly with the data from the “satellite receiver”.
A further important feature is the integral iGyro system. The PBR-7S, PBR-9D,
PBR-10SL and PBR-26D receivers have the iGyro software installed as standard,
providing control of six separate axes. To make use of the iGyro all you have to do
is connect an iGyro SAT to the FastTrack socket. If the integrated iGyro detects
a GPSIII or a PBS-TAV sensor on the P²-BUS, the gyro gain is even speed-com-
pensated!
All iGyro settings can be adjusted conveniently from the transmitter using the
Telemetry menu.
All PBR receivers are capable of generating various BUS signals at the FastTrack
socket, in order to maintain compatibility with third-part products such as heli-
copter gyros. In addition to S.BUS and SRXL, as of Version 3.5 an analogue PPM
signal can also be available.

One feature which is unique in the market is the facility to update receivers from
the transmitter. You do not even need to remove the receiver or receivers from
the model, or connect to the model using a laptop and USB interface, in order to
update the receiver software.

3. POWER SUPPLY
Power is supplied to the PBR-14D via the MPX high-current socket. Since there is
an integral electronic switch, no additional external components are required. The
PBR-14D can be switched on and off using either the integral blue push-button, or
a separately available MicroSwitch (#3584) or MicroMag (#3585).

This is the switching process: hold the push-button pressed in for about two
seconds, release the button briey, then press it a second time briey to conrm
the switching process. If you use the internal push-button, there is no visible
indication of the switching process, but you will see the switched status from the
LED which shows the receiver’s status. If you use the external MicroSwitch or the
MicroMag magnet switch, you will also see the switched status from the switch’s
integral LED.
4. BINDING
The transceivers can be bound using either of two methods:
a) Connect the transceiver rst
The LED now ashes rapidly for about ten seconds. Press “Bind” at the trans-
mitter, and the transmitter and receiver are bound. If you do not press Bind
within ten seconds, the receiver LED switches to a slower ashing rate. At this
point the receiver can no longer be bound to the transmitter unless the power
supply is rst disconnected.
b) Press “Bind” at the transmitter rst
After this you connect the receiver to a power supply: the transmitter now binds
with the receiver.
5. DETAILED DESCRIPTION OF THE SOCKETS
a) PWM outputs
The PWM outputs are sequentially numbered from 1 - XX, but are also assi-
www.powerbox-systems.com 7
gned the letters A - I. As an option, you can also set the receiver outputs to
generate different channel numbers. For example, the PBR-9D can be set to
generate outputs 10 - 19 as well as channels 1 - 9 *.
b) P²-BUS
This interface is used for the external ultra-fast P²-BUS telemetry system and
digital servo output. When the system is switched on, all the sensors connec-
ted to this socket are scanned, and displayed at the transmitter.
The P²-BUS socket can also be used for updating the receiver using the USB
interface adapter.
c) FastTrack/Data
This socket can be set to various functions from the transmitter: you can set it to
FastTrack, P2BusOUT, S.BUS, SRXL-16, PPM12 or even one further servo output.
• FastTrack
The iGyro SAT or a supplementary satellite receiver (PBR-26XS) can be
connected to this socket. FastTrack is a high-speed real-time bus system. If
you wish to use both the iGyro SAT and the optional satellite receiver simul-
taneously, they can simply be connected using a Y-lead. Once an iGyro SAT is
connected, you have a six-axis iGyro system whose full range of functions can
be adjusted from the transmitter.
•P2BusOUT
The purpose of this option is to feed telemetry data wirelessly from the model
to ground stations, as are typically used in Triangle ying events. The receiver
“listens” to the radio trac between the transmitter and the receiver in the mo-
del, and passes on the telemetry information from the model to the connected
ground station.

• PWM
If you select this option, you can connect an additional servo to the FastTrack/
Data socket. The channel generated varies according to the type of receiver
you are using. For example, if your receiver is a PBR-14D, then channel 15 is
available at this socket.
• S.BUS and SRXL-16
These digital bus signals can be processed by many gyros and battery ba-
ckers, and therefore serve as a universal interface for third-party accessories
such as helicopter gyros.
• PPM12
As of version V3.5, all receivers also offer the option of generating an analo-
gue PPM12 signal. One practical application for this is a wireless connection
for PC ight simulators.
6. MEANING OF THE LED DISPLAY
The integral LED can indicate various types of receiver status:
• Continuous blue light: the transceiver is bound to the transmitter;
signal strength is adequate
• Flashing rapidly blue: the transceiver is waiting for a binding signal
• Flashing slowly red: the receiver is picking up no signal
• Continuous red light: the update has failed, and the receiver is in bootloader
mode. Use the Rescue mode to restart the update process.

7. INSTALLATION, DEPLOYING THE AERIALS
All PowerBox receivers pcb´s are manufactured using the SMT method, and are
therefore extremely resistant to vibration and shock. The ideal method of moun-
ting the PBR-14D is to use the retaining plate supplied in the set. However, it can
also be secured to any rm surface using double-sided adhesive tape.
The ideal method of aerial deployment varies greatly according to the model, the
fuselage material and the receiver’s position in the model. For most cases we
recommend routing the aerials out of the fuselage, as this guarantees optimum
reception regardless of the materials of which the model is made.
8. OTHER SETTINGS
The transceivers offer a number of optional settings which can be selected at the
transmitter and sent via the radio link:
• Frame rate
This denes the servo signal repeat frequency. The default value for this setting
is 18ms. Modern digital servos can operate more accurately and smoothly at
12ms.
• A Start output
Offsetting the Start channel. This feature can be used to “cascade” receivers. For
example, you can set up a PBR-14D to generate channels 1 - 14, and an additio-
nal PBR-7S for channels 15 - 21.
• Hold/Failsafe
This setting is adjusted in the Function menu at the transmitter, and not at the
10 PowerBox-Systems − World Leaders in RC Power Supply Systems
receiver.
• iGyro
You can nd a detailed description of the iGyro’s features in the instructions sup-
plied with the iGyro SAT. The iGyro function integrated into PowerBox receivers
is completely identical to the iGyro function in our larger PowerBox systems or
the iGyro3xtra.
9. NOTES ON OPERATION
All PowerBox transceivers are able to transmit battery voltage and reception
quality by default. The following values are transmitted:
• Battery voltage
This shows the voltage present at the servo sockets. Please note: if you are
using a regulated battery backer, the value shown here is the regulated voltage,
not the battery voltage.
• RSSI
This value shows the input level at the aerial, and is displayed in dBm - a logarith-
mic power value.
• LQI
This value indicates the reception quality in percentage form. The value is calcu-
lated by the receiver, based on the number of lost data packets and the power
level over time.
LQI is a very instructive value providing information about the quality of the
