The receiver servo sockets are addressed in se-
quence; this is recommended for use with analogue
servos. At this setting the servos are automatical-
ly operated at a frame rate of 20 ms (30 ms with the
twelve-channel receiver, Order No.
33512
) - regard-

of the “

The receiver servo sockets are addressed in parallel
blocks of four, i. e. channels 1 to 4 and channels 5 to
8 each receive their control signals simultaneously.
This is recommended for use with digital servos, and
especially where multiple servos are employed for
a single function (e. g. ailerons), to ensure that the
groups of servos run absolutely synchronously.
If you are using digital servos exclusively, it is advis-
able to set a value of 10 ms in the “PERIOD” line of
the “
RX SERVO
” screen, as this enables you to ex-
ploit the fast response of digital servos. If you are us-
ing analogue servos, or a mixture of both types, it is
essential to select “20 ms”!
If you choose the faster setting, please take par-
ticular care when selecting the receiver power
supply:
since up to four servos can start moving si-
multaneously, the load on the battery is fairly severe,
so it must be a high-performance type.

SUMO
A HoTT receiver configured as SUMO constant-
ly generates what is known as a sum signal from the
control signals of all its control channels, and - in the
case of the GR-16 receiver supplied in the set as
standard - makes this available at servo socket 8.
If the receiver’s display shows a two-digit number to
the right of “SUMO” …

… then the active field shifts to the right - to channel

You can confirm the pre-set number with a further

of the other channels between 04 and 16, and then
confirm your choice with

The receiver outputs are addressed in sequence at a
frame rate of 20 ms (30 ms with the GR-24 receiver,
Order No.

), even if you have set 10 ms in the
“PERIOD” line of the “
RX SERVO
” screen page.
Although primarily intended for “satellite mode” with
two HoTT receivers, as described below, the sum
signal generated by the receiver defined as SUMO
can also be used, for example, to control a flybar-
less system, or to control a flight simulator (using the
adapter lead, Order No.
33310
).

Satellite mode
… two HoTT receivers are inter-connected using a
three-core connecting lead (Order No.
33700.1
(300
mm) or
33700.2
(100 mm)) using servo sockets de-
termined according to the specific receiver types. For
example, GR-16 and GR-24 receivers are inter-con-
nected using servo output 8. For more details on this
please refer to the Internet at www.graupner.de.
All channels of the HoTT receiver which is configured
as SUMO, and is defined 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 …
