By means of this connection, all of the channels
selected in the "CH OUT TYPE" line of the HoTT
receiver configured as a SUMO and identified as the
satellite receiver are continuously transferred to the
second HoTT receiver, the main receiver, that needs
to be programmed as the …
• SUMI (aggregate signal IN)
The signal therefore always runs in the direction of
the SUMI:

When reception fails, the receiver defined as SUMI
only uses the aggregate signal coming from SUMO
if at least one channel is programmed as fail safe in
the SUMI.
If the reception fails of the receiver programmed as
the SUMO satellite receiver, the servo(s) connected
to this receiver assume the fail safe positions that are
programmed in the satellite receiver independent of
the main receiver.
If the reception fails for both receivers, then the
fail safe settings of the SUMO are assumed in the
receiver software current when these instructions
were revised.
In individual cases, interactions may occur.
It is therefore strongly recommended
that relevant tests be performed before
starting the model.
This receiver configuration is recommendable when
for example one of the two receivers is installed
in the model at a location with poor reception, or
nozzles, carbon fiber material, etc. may weaken the
reception depending on the flight direction is which
can restrict the range.
The most important control function should therefore
be associated with the main receiver programmed
as SUMI so that, in case of a malfunction, the model
can still be controlled if the SUMO satellite receiver
no longer receives a good signal. Connect telemetry
sensors with the SUMO satellite receiver, and then
select this receiver in the line "RECEIVER SELECT"
of the "Telemetry" menu (RX 1 … 2), see "Important
instructions" on page 114.
Each receiver should be connected to the common
power supply with its own cable. With receivers
subject to high current load, it may even be useful to
connect them to the common power supply with two
cables.
If in contrast each of
the two receivers are
connected to their
own power supply, the
middle cable should
be removed from one
of the two plugs of the
satellite cable (see
figure).
If you wish to do additional programming such
as fail safe settings, disconnect the 3-pin satellite
connection between the two receivers, and only
switch on the relevant receiver. You may also have to
change the binding sequence.
• SUMD (digital sum signal)
A HoTT receiver configured as SUMD as described
earlier always generates a digital aggregate signal
from the control signals of a selectable number of
its controls channels, and forwards this to servo
connector 8 in the GR-16 and GR-24 receivers.
At the time this manual was revised, this type of sig-
nal was being used by several of the latest electro-
nic applications of flybarless systems, power sup-

plies, etc.
You therefore need to consult your
setting instructions for the attached
device since otherwise you may make it
impossible to fly the model.

After confirming "SUMD" by touching the SET
button at the bottom right in the display, the active

• HD ("hold")
The last signals recognized as being correct are
retained at the output (hold).
• FS (fail safe)
The signals of previously-saved fail safe positions
are provided at the output, see the section "Fail
Safe" on page 84.
• OF (OFF)
No signals are supplied for the duration of the
loss of reception.
