Setting The Battery Type; Setting The Output Voltage; F) Channel Assignment, Output Side - PowerBox Systems Champion SRS Instruction Manual

Spektrum DSM2 and DSMX:
If you select Spektrum DSM2 or DSMX, the additional menu point BIND now appears. Whether you select the
DSM2 or DSMX option depends on your transmitter type - not on the satellites connec- ted to the system. For
example, if your transmitter operates on DSM2, but the satellites are DSMX types, select DSM2 at this point (for
example, this applies to all Spektrum modules fitted to MC-24 transmitters).
Now connect your satellites, and select the BIND menu point; at least three satellites must be connected. Even if
two of three satellites were to fail in flight, SRS technology allows the PowerBox to continue to function correctly
with just a single satellite.
All satellites connected to the system now flash, and can be bound to the transmitter.
The following systems are connected to inputs RX1 and RX2 using the three-core patch-leads sup- plied in the
set:
Futaba S-BUS:
Set the receiver or receivers to "Normal Mode" - not "High-Speed Mode".
If you are using the R7008SB receiver it is particularly important to set Output 8 to S-Bus, and to use this output.
Do not use the S-Bus2 output! Naturally the receiver's S-Bus2 socket can be used for Futaba telemetry acces-
sories.
Multiplex M-Link:
The MPX receiver or receivers must be set to "Digital Output". This can be selected using the Pro - Mate device or
a USB adapter (Multiplex or PowerBox USB interface) and a PC. The software required for this is called "Multip-
lex Launcher", and is available as a free download from the Mul- tiplex website. You should also set the fail-safe
time to 0s; this is important if you wish to use two receivers, as it ensures a fast switch-over if signal loss occurs.
Graupner HoTT:
If you wish to use a HoTT receiving system, the SUMD signal must be activated at the receiver. Use the SmartBox
or the transmitter's Telemetry menu to set "CH OUT TYPE: SUMD OF 16".
"OF" means that the receiver switches the SUMD signal off if signal loss occurs. The SRS system detects this
within a few milliseconds, and switches over to the second receiver. If you intend to use only one receiver, you
can also set FS or HD.
Jeti Duplex:
Connect two R-Sat2 satellites or REX receivers directly to RX1 and RX2. The receivers are bound in two-way
mode. The following settings must be carried out:
- Serial output: UDI
Primary settings:
- Signal speed: 10 ms
- PPM settings: Direct
- Failsafe: Inactive (if two receivers are in use; otherwise any setting)

d) Setting the battery type
It is essential to set both the battery type and the ca-
pacity of the batteries you intend to use, otherwise
accurate battery monitoring will not be possible. You
will find this set-up point in the POWER/TELEMETRY
menu:
- CHEMISTRY: Select one of the four battery types: LiPo, LiIon, NiMH or LiFePo
- CAPACITY: Select the capacity of your batteries at this point. Since V12 the PowerBox detects that a charge
process is under way, and automatically resets the residual capacity display. However, it is also possible to reset
the capacity manually by holding buttons I and II pressed in simultaneously.
e) Setting the output voltage
The Champion SRS is fitted with a total of four independent high-performance voltage regulators. In order to
guarantee 100% redundancy, these are linked together in pairs. You can select the output voltage of each of these
regulator pairs A and B. For example, it is possible to set an output voltage of 7.4 V for regulator pair A, and 5.9
V for regulator pair B. This feature makes it possible to connect a mixture of HV servos and normal servos to
the PowerBox Champion SRS. The markings A (red) and B (black) on the case cover indicate which outputs are
assigned to range A, and which to range B. The Output Mapping function provides a comprehensive means of
assigning the appropriate output voltage to particular functions.
Note: the PowerBus outputs are also assigned to voltage range A and voltage range B.

f) Channel assignment, output side

As already mentioned, the outputs of the PowerBox Champion SRS can be assigned in any way, without restric-
tion. This means that particular functions or channels can be assigned to any of the 24 outputs. The menu point
where this is carried out is entitled OUTPUT MAPPING:
