• 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, see more about on in the
SUMO section, and forwards this to servo connec-
tion 8 in the GR-16 and GR-24 receivers.
At the time this manual was revised, this type of
signal was being used by several of the latest elec-
tronic applications of flybarless systems, power
supplies, etc.
Notice
You therefore need to consult your setting in-
structions for the attached device since oth-
erwise 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
value field switches to the right for selecting one
of the three possible receiver reactions in case of
a loss of reception (fail safe):
• 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 posi-
tions are provided at the output (see the sec-
tion "
Fail Safe
").
• OF
(OFF)
No signals are supplied for the duration of the
loss of reception.
Attention
Analogue servos and many digital servos
no longer experience resistance to the on-
going control pressure after control pulses
stop and are moved out of their position at great-
er or lesser speed.
Finally, switch the active field to channel selec-
tion by touching the
SET
button at the bottom
right. With the selection, you determine the
high-
est
transmitter channels within the SUMD signal.
Tip
Normally, a value greater than "12" is not required
by potentially connectible devices.
