2PowerBox-Systems − World Leaders in RC Power Supply Systems
Dear PowerBox Customer,
Congratulations on your decision to install a PowerBox PBR-12X in your model.
This unit represents the most compact power supply system available anywhere
at present.
The PBR-12X offers full telemetry capability in addition to its role as high-perfor-
mance power supply system with electronic switch.
We are condent that you will have great pleasure and success with your PBR-12X!
1.Installation, connections
In order to minimise the unit’s dimensions, the case does not feature mounting
lugs; instead the PBR-12X is installed using the self-adhesive pad supplied in the
set. Since the unit is so light and compact, this represents an excellent method of
mounting.
The PBR-12X can be used with any of four radio control systems: PowerBox
CORE/ATOM P²BUS, Jeti EX-BUS, Spektrum SRXL2 and Futaba S.BUS2. All four
systems share a particular characteristic: servo-signals and telemetry data are
carried on a single bus cable. This eliminates the need for a second patch lead for
telemetry data, as is still required for other systems.
The PBR-12X automatically detects the system to which it is connected; it may
take a few seconds for the system to be recognised unambiguously the rst time
it is plugged in. However, once detected, the type is saved, and the system starts
without delay next time it is switched on.
This means that the system is Plug‘n Play, unless you wish to adjust the fail-safe

www.powerbox-systems.com 3
positions, the frame rate or the capacity reset channel.
CORE- and Jeti-users have the facility to carry out all adjustments from the trans-
mitter. Alternatively a USB-adapter can be used; this is a requirement for Futaba
and Spektrum pilots. With this arrangement everything can be set up using the
associated Terminal-App.
Connecting the battery
It is essential to maintain correct polarity. Use the adapter lead; if you wish to use
a connector other than the MPX connector, note that red = positive and black =
negative.
Connecting the switch
Plug the switch into the appropriate socket. The PBR-12X can be supplied either
with a button switch or the MicroMag magnet switch.
The button switch operates in the same way as with all PowerBox systems: hold
the button pressed in until the LED starts ashing at a high rate. Release the button
briey, then press it again briey: the LED now glows a constant green to indicate
that it is switched on. Repeat the procedure to switch off.
If you have a MicroMag switch, hold the magnet over the switch until the, PBR-12X
switches on. The LED turns blue as soon as the switch registers a magnet. When
the switching process is complete, the LED turns red. The LED then glows green to
indicate that it is switched on.
Connecting the USB interface adapter
If required, the USB interface adapter should be plugged into the input socket mar-
ked RX2. The RX2 input can only be activated for Terminal when it is switched on.
If you have already connected a receiver to RX2, you must restart the PBR-12X
without a receiver at RX2 in order to activate the Terminal function.

If you wish to enter the fail-safe positions with a Futaba or Spektrum system, you
must rst bind RX1 to the transmitter; you can then start the Terminal-App on your
PC. The PowerBox Terminal-App is available for downloading from our website.
PowerBox and Jeti pilots have the facility to carry out all adjustments from the
transmitter.
2. Connecting to the radio control system
PowerBox CORE
Connect the P²BUS output of one or two receivers to the sockets marked RX1 and
RX2. If you are only using one receiver, this must be connected to RX1 in order to
transfer telemetry data.
Jeti EX-BUS
Set one output of the receivers you intend to use to EX-BUS. The frame rate should
be set to 10ms, and the Failsafe-function must be switched “OFF”. If only one recei-
ver is connected, this must be connected to RX1 in order to transfer telemetry data.
Futaba S.BUS2
Connect the S.BUS2 output of one or two receivers to the sockets marked RX1
and RX2. If only one receiver is connected, this must be connected to RX1 in order
to transfer telemetry data. At the transmitter this receiver must also be set as the
Telemetry receiver.
To receive telemetry data you must carry out a “Load New” process at the trans-
mitter in the Telemetry Sensor menu; this action completely erases the sensor list.
Now select Slot 1 in the sensor list, and choose “Cur.F1678”. The telemetry data
now appear in Slot 1 onwards.

Spektrum SRXL 2
Use the optional adapter lead set (#9192) to connect one or two SPM4651T satel-
lites to the PBR-12X. If only one receiver is connected, this must be connected to
RX1 in order to transfer telemetry data. The battery data are now displayed at the
transmitter under PowerBox Sensor. The receiver data can be seen in RX data at
the transmitter in the usual way.
By default the PBR-12X operates in DX18 compatibility mode.
3.Settings
The PBR-12X requires only a few adjustments. You will nd all the settings either
in the transmitter menu (CORE, ATOM, Jeti), in PC-Terminal or in Mobile-Terminal.
To reach the menu with a PowerBox CORE/ATOM transmitter, set up any telemetry
widget for the PBR-12X in the usual way-. You will then see the Menu button in the
widget.
With a Jeti system you will nd the Jetibox point under Auxiliary Functions. Select
this point, and press MX at far right. If you now press at the bottom, you will nd
yourself in the PBR-12X menu again.
a) Frame rate
This function is used to adjust the signal repeat rate to match the servo. For older
analogue servos we recommend the 18ms setting; for more recent digital servos
you can select 12ms. The default setting is 16ms.

b) Capacity reset channel
This function can be used to select the channel which resets the consumed capa-
city; the default setting is channel 16. This channel resets the consumed capacity
when the travel exceeds 100%. You can use a switch or a button for this, and reset
the capacity value once the battery has been charged.
c) Failsafe
In this menu you can select an output which you wish to run to a particular servo
position if the radio signal should be lost. You should always assign this function
to throttle, as this is a legal requirement in many countries.
Select your preferred output, and set the Failsafe mode to Failsafe. Pressing the
Teach button accepts all the current servo positions for all outputs which are set to
Failsafe. RX1 must be bound to the transmitter when you make this setting.

4. Meaning of the LED codes
The integral LED indicates various states relating to the receivers. This enables you
to ascertain whether the receivers are working properly.
LED ashes slowly,
alternating red and blue
No receiver connected,
RX2 in Terminal mode
LED constant blue RX1 connected
LED constant red RX2 connected
LED constant violet RX1 and RX2 connected
LED ashes blue at high
rate RX1 lost
LED ashes red at high
rate RX2 lost
LED ashes violet at
high rate RX1 and RX2 lost
