Dear PowerBox customer,
Congratulations on your new PowerBox power supply unit! The PowerBox Mercury
SR2 is your rst choice when you need a small, high-performance power supply unit
with maximum functionality. All the features which are usually the preserve of the
larger power supply units are present in the compact PowerBox Mercury SR2: iGy-
ro, servo matching, unrestricted channel assignment and even a door sequencer: it
really is a complete system!
The PowerBox Mercury SR2 provides 16 freely assignable outputs with servo
matching, i.e. the travel of each channel can be adjusted at ve points. If you y mo-
dels with large control surfaces, in which individual control surfaces are actuated
by two servos, the unique auto-match function can be used to match both servos to
each other accurately in a matter of seconds.
The integral iGyro software requires a sensor unit in the form of an iGyro SAT; with
this it can address and adjust three aileron, three elevator and three rudder func-
tions individually. The Setup Assistant simplies the initial adjustments to the gyro
system, reducing the time required to just a few minutes. The rst time the system
is used, the Assistant gathers basic information regarding wing and tail format and
the vector control system - if present. A complex model matrix then works in the
background, calculating which servo needs to be connected to which output, at
the same time linking the corresponding gyro function. A wide range of additional
Expert settings offers total freedom, enabling you to ne-tune the gyro system to
your particular requirements.
In addition the GPSIII or PBS-TAV (True Airspeed Vario) can also be connected to
the FastTrack input, making it possible to vary gyro gain according to airspeed. All
GPS or TAV information is even available for telemetry at the transmitter!
The PowerBox Mercury SR2 supplies a regulated output voltage which can be set
to 6.0V or 7.8V. The two voltage regulators offer generous capacity thanks to the
machined aluminium heatsink on the top and bottom surfaces, enabling the unit to
cope effortlessly with the current-hungry servos used in 3D machines.
The integral door sequencer is capable of controlling one undercarriage system and
up to three wheel doors. If the Setup Assistant is used, it takes just a few minutes
to learn the end-points of door travel, while three pre-dened modes cover the vast
majority of undercarriage processes. Once initially set up, the timing of the process
can be ne-tuned manually to any values you wish.

For PowerBox and Jeti pilots it is possible to control and adjust virtually every* as-
pect of the PowerBox Mercury SR2 from your transmitter! Full telemetry for battery
and receiver data is present for all supported systems
*With the exception of the door sequencer and Setup Assistant

2.INSTALLATION, CONNECTIONS
a) Mounting
The PowerBox Mercury SR2 should be mounted in the model on a robust sub-struc-
ture using the four screws, rubber grommets and brass eyelets supplied in the set.
The installed location is not important, but if an iGyro SAT is to be used, the sensor
must be installed perpendicular to the model’s centreline. Ideally the TFT screen
should be in a clearly visible location. The bright screen lighting makes it easy to
read even in sunshine, so no special provisions have to be made here. The screen is
connected to the socket marked Display on the side of the PowerBox.
The switch should be mounted in the fuselage side. As with previous units, a woo-
den doubler should be glued to the inside of the switch aperture - especially if the
fuselage is made of GRP - in order to avoid subjecting the switch to powerful vi-
bration. The set includes a template for the switch aperture. An exposed switch is
www.powerbox-systems.com 5
often undesirable in scale models, and for such applications we offer an alternative
switch in the shape of the MagSensor. However, please note that the SensorSwitch
is required for the programming procedure - unless you are using a PowerBox or
Jeti RC radio system - and for this reason it should always be available for use. The
SensorSwitch is plugged into the socket marked Switch on the side of the Power-
Box.
b) Receivers
Once you have installed the PowerBox Mercury SR2, the screen and the switch, it is
time to connect the receivers. In principle all SRS PowerBox systems are totally reli-
able when used with a single receiver. However, in view of the low cost of a second
receiver compared with the value of the model, we always recommend installing a
second receiver.
Ideally the receivers should be spaced well apart inside the model, as this increa-
ses the likelihood that at least one receiver will have good reception at all times
- even under difcult reception conditions. It is permissible to extend the serial bus
connection between receiver and backer to any length, as the signal is digital, and
therefore extremely resistant to external inuences.
The PowerBox Mercury SR2 can be used with a wide range of radio control sys-
tems: PowerBox CORE P²BUS, Futaba S.BUS2, Jeti EX-BUS, Spektrum SRXL2,
Multiplex M-Link, JR DMSS and Graupner Hott. The rst four systems share one
common feature: servo signals and telemetry data are carried on a bus system, and
this allows the receivers to be connected to the Mercury SR2 using a single patch
lead each. Multiplex and Hott systems require an additional connection between
the TELE- output of the PowerBox and the receiver’s telemetry input.
The PowerBox Mercury SR2 automatically detects the system to which it is
connected. However, when the radio is rst switched on it may take a few seconds
before the system is unambiguously recognised. Once detected, the unit stores the
system type, and it will start immediately next time it is switched on.
• PowerBox ATOM/CORE
Connect one or two receivers to RX1 and RX2 at the P²BUS output. If only one
receiver is to be used, it must be connected to RX1 to provide telemetry transmis-
sion. If a GPS III or a PBS-TAV is connected to the FastTrack input, the Mercury
also delivers this ight data to the transmitter.
6PowerBox-Systems − World Leaders in RC Power Supply Systems
• Jeti EX-BUS
One output of the receivers you intend to use must be set to EX-BUS. The frame
rate should be set to 10ms, and the Failsafe function must be OFF. If you intend
to use only one receiver, then it must be connected to RX1 to transmit telemetry
data. If a GPS III or a PBS-TAV is connected to the FastTrack input, the Mercury
also delivers this ight data to the transmitter.
• Futaba S.BUS2
Connect one or two receivers to RX1 and RX2 at the S.BUS2 output. If only one
receiver is to be used, it must be connected to RX1 to provide telemetry transmis-
sion. This receiver must also be dened as the telemetry receiver at the transmit-
ter. In order to receive telemetry data, you must carry out a Load New process in
the Telemetry Sensor menu; this action completely erases the sensor list. Now
select Slot 16 in the sensor list, and select PowerBox. The telemetry data now
appear in Slot 16 or later. If a GPS III or a PBS-TAV is connected to the FastTrack
input, the Mercury also delivers this ight data to the transmitter.
Note: do not attempt to register the PowerBox as a sensor at the transmitter; this
function is not implemented.
• Spektrum SRXL 2
Connect one or two SPM4651T satellites to the PowerBox Mercury SR2 using
the optional adapter lead set (#9192). If only one receiver is to be used, it must
be connected to RX1 to provide telemetry transmission. At the transmitter you
will now see the battery data displayed under PowerBox Sensor. If a GPS III or a
PBS-TAV is connected to the FastTrack input, the Mercury also delivers this ight
data to the transmitter.
By default, the Mercury works in DX18 compatibility mode.
• Multiplex M-Link
Set the B/D sockets of the receivers you intend to use to SRXL V2. This gives you
sixteen channels. The Failsafe function must be OFF.
To use telemetry, you must disable the Telemetry function of one receiver using
Multiplex Launcher. The Tele output of the PowerBox should be connected to the
Sensor input of the other receiver.
If a GPSIII or a PBS-TAV is connected to the FastTrack input, the Mercury also
delivers this ight data to the transmitter.
Note: do not attempt to register the PowerBox as a sensor at the transmitter;
this function is not implemented.

• Graupner Hott
Set one output of both receivers to SUMD-OF16. For example, if the receiver is a
GR16/24, this will be output 8. Connect these outputs to the RX1 and RX2 inputs
of the PowerBox. If a GPS III or a PBS-TAV is connected to the FastTrack input,
the Mercury also delivers this ight data to the transmitter.
For the telemetry function, you must connect the TELE output of the PowerBox to
the Telemetry input of one receiver.
c) Connecting the batteries
It is possible to use 2S LiPo, 2S LiIon, 2S LiFePo or 5S NiMH batteries with the
Mercury SR2. We recommend that you use our PowerPaks, which feature integral
charge electronics. The fundamental rule regarding battery size is that one battery
on its own should be capable of powering the model reliably.
If you intend to assemble your own batteries, please note that correct polarity is
vitally important. The unit does not include reverse polarity protection, as this would
involve performance losses.
3.SWITCHING ON AND OFF
This is the procedure for switching the PowerBox on: hold the SET button pressed
in until the LED glows red. Continue to hold it pressed in while you also press but-
tons I and II briey to conrm the switching process. This method enables you to
switch the batteries on individually; for example, in order to check that both packs
are working properly, and deliver sufcient current when all the control surfaces
are moved.
The same procedure is used to switch off.
Note: Only one receiver (Bind A or Bind B) can transmit telemetry!
Note: Connecting a battery to the PowerBox with incorrect polarity, even very
briey, will immediately destroy the voltage regulators!

The OLED screen now displays the following image:
Analogue and digital battery voltage display. The scale of the analogue display
is matched to the battery type you have selected. The supplementary digital
display states the exact value.
Digital current display: shows the current which is drawn from each battery
individually.
Display of the voltage which is actually available at the output.
The consumed capacity is displayed separately for both batteries. It can also
be reset from the transmitter using a channel.
At this point the status of the receivers, gyro and GPS are displayed.

4. MAIN MENU
To access the menu you need to hold the SET button pressed in for about 2 - 3 se-
conds, after which you can select the desired menu using buttons I and II.
Press the SET button once you have selected a menu point. You can now alter the
values and settings using buttons I and II.
The “Rotary Menu” shown above contains the following sub-menus:
• iGyro
Here you will nd all the settings relating to the iGyro. These features are only
available if an iGyroSAT is connected to the unit.
• ServoMatching
If you have servos which are mechanically inter-connected, you can use this sub-
menu to adjust them to match each other using a ve-point curve. You will also
nd the Auto Matching function here.
• Sequenzer
At this point you can set up the door sequencer, either manually or with the help
of the Assistant.
• Output Mapping
In this menu you can assign all 16 outputs directly to any transmitter channel, to
a Gyro output or the door sequencer.
• Input Mapping
The transmitter channels are assigned to the iGyro or sequencer here.
10 PowerBox-Systems − World Leaders in RC Power Supply Systems
• Basics
This menu is used to alter fundamental settings such as the language or frame
rate.
• Assistent
Always use the Setup Assistant when you are preparing a new model for its rst
ight. This is where the transmitter input channels are determined, the model type
selected, and the servos assigned to the outputs. In just a few minutes the pri
mary functions can be ready for use, and the Assistant procedure makes it much
easier to set up the gyro functions at a later stage.
• Reset/Update
At this point you can reset individual ranges. The Update point activates the Data
port for connection to a PC using the USB interface lead (#9020).
5. BASIC SETTINGS
Before you start using the primary functions (with the help of the Setup Assistant)
and connect the servos, you should enter the basic settings in the General Settings
menu.
• Radio control system
This menu point cannot be selected manually. As already mentioned, the unit au-
tomatically detects the radio control system. If you have already connected your
receivers and bound them to the transmitter, you will see at this point the radio
control system it has detected.
