DDS-10 receivers feature 10 sockets for connecting conventional servos with 3-pin UNI flat plugs. The signal wire (yellow / orange / white) must be at
the top, the negative wire at the bottom. An 11th AUX socket is provided for connecting external LED indicators. The power supply can be connected
via any one of the servo sockets, or via the separate DSQ 3-pin high-current socket.
Caution: do not connect a battery to the AUX socket. The switch output could be ruined if you insert the connector incorrectly.
Unless otherwise defined by programming, signals are only passed to those servo outputs to which a transmitter signal is assigned. For example, if the
transmitter only generates eight channels, then no signal is present at servo outputs 9 and 10. The same applies whether the transmitter generates 7, 9
or 12 channels. Graupner transmitters, for example, can be set to transmit PPM18 / PPM24 and SPCM. If you wish to control twelve channels (servos),
two receivers must be used in Diversity mode; in this case the channels have to be assigned accordingly in the programming process.

Connecting servos to the DDS receiver
Caution: The signal side (servo signal) of the connector contacts (yellow or orange wire in the servo cable) must always be at the top. The receiver
outputs are numbered sequentially from left to right. Servos with JR / Futaba plugs can be connected directly; you only need to ensure that none of the
connectors is offset (only 2 of 3 pins engaged) when inserted. The plugs must be fitted with the negative (-) wire facing the receiver circuit board (down);
the actual colour of the negative wire is shown in the table on page 3. The signal wire (yellow or white) must be at the top on the receiver.
Setting the receiver channel and modulation (DDS receivers only)
The reception channel (and the PPM / PCM modulation in the case of PCM receivers) is set using the "transmitter search" (scan) facility. The
programming shorting plug (supplied) must be connected to the DSL socket before the receiving system is switched on.
In Scan mode (with programming plug fitted) the receiver's transmitter scan program detects the most powerful transmitter. This is normally the owner's
transmitter, i.e. the one which is nearest to the receiver. When the Scan process is finished, the detected spot frequency and modulation (PPM, PCM
1024, S-PCM) are stored permanently in the receiver; the data is retained until you initiate a new Scan process. Once the scanning process is
concluded, the servos can be controlled from the transmitter in the normal way.
1.) To start the transmitter search, the supplied programming lead with shorting plug must be connected to the 4-pin DSL socket.
2.) Attach the aerial to the transmitter and place it close to the receiver. Switch the transmitter on, operating on your chosen channel.
3.) Switch the receiver on; the scan begins, and is completed within max. 3 seconds (PCM: 1 - 2 minutes). The servos can then be controlled from the
transmitter.
4.) Disconnect the bridging plug (shorting plug with lead) (or see Fail-Safe below).
The receiver can pick up all channels in the 35 MHz band which are approved for use in Europe.
Fail-Safe
All DSL receivers can be programmed with user-variable servo positions which are triggered when interference occurs. In the default state the receiver
is set to HOLD mode; this means that, if interference strikes, the servos maintain the last positions detected as good; these settings are frozen until the
interference is passed.
This is the method of defining the servo Fail-Safe positions: operate the transmitter's controls to move the servos to the positions which they (and
therefore the model's control surfaces) are to take up when interference occurs. The programming plug is then used at the receiver to carry out the
actual programming.
The programming plug is used to select "Fail-Safe" or "Hold": switch on the transmitter. For Fail-Safe, operate all the transmitter sticks and other
controls to move the servos to the positions which they are to take up when interference occurs, then connect the programming plug and switch the
receiver on.
Disconnect the programming plug: within 10 seconds --> this sets only the spot frequency and modulation; --> existing programmed servo travel
settings (via PC / Palm) are not erased.
Disconnect the programming plug: within 10 - 20 seconds --> this sets the spot frequency, modulation and Hold for interference; existing programmed
servo travel settings are erased.
Disconnect the programming plug: within 20 - 30 seconds --> this sets the spot frequency, modulation and Fail-Safe for interference; existing
programmed servo travel settings are not erased. If you wish to set Fail-Safe positions only for particular servos, e.g. throttle, you need to carry out the
programming using a Palm or PC.
In the case of the DDS-10 you can only set Fail-Safe or Hold at the receiver using the PC or Palm. If you do not have a programming device for the
receiver, you can still use the normal programming procedure provided by your PCM transmitter to program the Fail-Safe settings.
Power supplies - DDS-10
A JR-system battery connector can be connected to any of the ten servo sockets. However, if you need to provide a high-current supply to the servos,
the DSQ high-current socket must be used. This makes full battery power (up to 15 A) available to each servo directly; no supplementary high-current
power supply for the servos is required, as the conductor tracks inside the receiver are of very generous dimensions, and are more than capable of
supplying even the most powerful servos directly. We recommend that you use the high-current socket if you are using five or more powerful servos -
especially if they are digital types. To exploit this feature simply use the two-core DSQ cable supplied.
Operating voltage
DDS receivers continue to operate with undiminished range at a voltage of 3.5 Volts, but the servos have less power and run significantly more slowly.
This means: take care if you notice the servos running slowly: the battery is flat or defective. Maximum voltage is 8.5 Volts; the use of 5-7NiCd cells or
two LiPo cells presents no problem to the receiver, but some servos are not designed to run on five battery cells (> 6 V).
The use of 2 DSL receivers in a Diversity group.
In addition two DSL receivers must be connected with the DSL cable or by the Irda interface. Then automaticly Diversity-Mode starts to work with all
advantages of the Diversity system. Without any programming the two receivers communicate automatically with one another via the DSL cable and
increase thereby the transmission reliability substantially. All further possibilities of the DSL system can be used in connection with a PC or Palm mini
computer with the DSL receiver system. The functions of the DSL system are very extensive, therefore a complete guidance is available on our

Notes on Appropriate use
The receiver may be used exclusively in remote-controlled models or for frequency check.
In the case of utilization in
bigger airplanes
with many leads we recommend ring filters. Particularly a full range test must be carried out,
because
long
s are changing the
RF-environment
The range at the ground should be at least 50 m, it must not be a great difference between range of the built-in receiving installation and
range with receiver and servo without model. It must not be a great difference between range with standing engine and range with current
engine. In this case the receiving installation must always work without mistakes.
Pilots must stand during the use always together, far away positioned pilots can disturb the reception, if a model approaches flies close to
the further pilots standing away.
Always switch ON first the transmitter, then the receiver.
