Telemetrie - PowerBox Systems Royal SRS Instruction Manual

However, until now there has always been one drawback: if a short-circuit occurs in one servo, this
blocks the bus lead, and all the servos connected to it stop working. Here at PowerBox-Systems we
have now completely eliminated this former disadvantage:
The servo distributors which we have developed are protected against short-circuits in the power
supply wires and the signal wire! This means that if one output is shorted out at a servo distributor,
that output is switched off within a few micro-seconds, and the bus lead remains active.
This supplementary feature is very important to flight safety, since a servo bus without it is not
suitable for use in valuable model aircraft!
Another important point relating to servo bus systems must be taken into account: the more servos
connected to the servo bus, the higher the current that flows, and the more severe the demands on
the wiring system. The PowerBUS system is Plug-n-Play: our range of products includes special
leads of different lengths, fitted with connectors encapsulated using the HotMelt process.
The PowerBUS system does not necessarily require bus-enabled servos. If you wish to use con-
ventional PWM servos with the PowerBUS, you can use a PowerBUS distributor which converts the
digital bus signal into PWM signals.
Three different types of distributor are available:
- Order No. 9200: PowerBUS to PWM
- Order No. 9210: PowerBUS to BUS
- Order No. 9220: PowerBUS Splitter

11. TELEMETRIE

The Royal SRS makes battery, receiver and GPS data available as telemetry information which can
be exploited by various makes of radio control system. The unit supports the following makes of
equipment, and other systems will gradually be introduced as updates become available:
- Jeti EX
If you wish the transmitter to receive telemetry data, connect the PowerBox output TELE to the EXT
input of your receiver. Battery, receiver and GPS data are transmitted.
- Futaba
If you wish to use telemetry, you will need the PowerBox Teleconverter, which is available as an
optional accessory. This is used to connect the TELE output on the PowerBox to the S-BUS 2 input
of your receiver.
- Spektrum
Connect the four-pin Spektrum TELE output to the TM1000, and also the three-pin TELE output to
the Data Port of the TM1000. Bind the TM1000 and the connected satellites to the transmitter. Acti-
vate the PowerBox Telemetry display at your transmitter. The battery voltage and residual capacity
for both batteries, plus the receiver data, are now available at the transmitter.
For additional information on the binding procedure and the cables required please refer to the FAQ
section of our Forum.
- HoTT
Connect the backer's TELE output to the receiver's Sensor input using a standard commercial Uni
patch-lead. The transmitter detects the PowerBox as an "Electric Air Module" and a "GPS Module".
Battery and GPS data are displayed on the transmitter.
- JR
If you wish the transmitter to receive telemetry data, connect the PowerBox TELE output to the
SENS input of your receiver. Battery data are displayed on the transmitter.
- Multiplex MSB
Connect the backer's TELE output to the receiver's Sensor input using a standard commercial Uni
patch-lead. Battery and GPS data are now displayed on the transmitter.
