Intended primarily for the following described „satel-

ver generated sum signal SUMO can be used, for ex-
ample, also for Flybarless systems or via the adapter

All channels of the HoTT receiver which is confi gured
as SUMO, and is defi ned as the satellite receiver, are
constantly transferred to the second HoTT receiver -
the primary receiver - via this connection . The prima-
ry receiver must be programmed as the ...
• SUMI (Sum signal IN).
Note that the signal only ever moves in one direction:
towards the SUMI.
However, if reception fails, the receiver defi ned as
SUMI only uses the sum signal coming from the
SUMO if at least one channel at the SUMI is pro-
grammed to Fail-Safe.
If the receiver programmed as the satellite (SUMO)
suffers signal reception failure, the servos connected
to that receiver take up the Fail-Safe positions pro-
grammed in the satellite receiver, regardless of the
primary receiver.
If, in contrast, reception fails at both receivers simul-
taneously, then the receiver software (the version
current at the time of printing these instructions) al-
ways reverts to the SUMO's fail-safe settings. Howe-
ver, mutual interactions can certainly not be ruled
out in individual cases, and for this reason we ur-
gently advise you to carry out appropriate tests
BEFORE fl ying a model.
This receiver confi guration is recommended in parti-
cular circumstances: for example, if one of the two re-
ceivers has to be installed in an unfavourable position
in the model, or if there is a danger that the received
signal will be weak in certain fl ight attitudes, perhaps
due to a turbine, carbon fi bre in the airframe, or a si-
milar problem, with the result that sporadic range pro-
blems might be expected.
For this reason it is essential to connect the most im-
portant control functions to the primary receiver (the
one programmed as SUMI), so that interference to
the satellite receiver (SUMO) does not cause the mo-
del to go out of control.
Telemetry data, such as the voltage of the airborne
power supply, are only sent to the transmitter by the
satellite receiver (confi gured as SUMO), i. e. all tele-
metry sensors must be connected to the satellite re-
ceiver (SUMO).
Each receiver should be connected to the shared po-
wer supply using its own power lead. If high currents
can be expected, duplicated power connections are
recommended. However, if each of the two receivers
is to be powered by its own battery, then it is
essential to withdraw
red
the central (red) wire

from one of the two sa-
2
tellite lead connectors,
as shown in the illust-
ration.
If you wish to carry out further programming, such
as the Fail-Safe settings, disconnect the three-core
satellite connection between the two receivers, and
switch on just the receiver you wish to address. Note
that you may also need to change the binding se-
quence.
