The sum signals of the channel 1 ... X will be generated in a 20 m s
cycle (in the GR-24 and GR-32 receivers, 30 m s) to the related out-
put, also if on the "RX SERVO" display page in the "PERIOD" line
10 m s has been set.
Primarily conceived for the satellite operation (described below) of
two HoTT receivers, the aggregate signal that is generated by the
receiver and defined as a SUMO can also be used to control a flybar
system, providing that it has an appropriate input, or it can be used
to control flight simulators by means of the adapter cable (No.
33310).
satellite mode
If in satellite use, two HoTT receivers are connected to each other by
means of a three-wire connecting cable (order No. 33700.1 (300 m m)
or 33700.2 (100 m m)) to servo connections for specific receiver
types. Type GR-16 receivers (order No. 33508) and GR-24 (order No.
33512) are for example connected to each other at servo output 8.
Further information can be found on the Internet at www.graupner.de.
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 iden-
tified as the satellite receiver are continuously transferred to the sec-
ond HoTT ...
SUMI (aggregate signal IN)
receiver (the main receiver) that needs to be programmed. The sig-
nal 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 1 channel is pro-
grammed as fail safe in the SUMI.
If the reception fails of the receiver programmed as the SUMO sat-
ellite receiver, the servo(s) connected to this receiver assume the fail
safe positions that are programmed in the satellite receiver indepen-
dent 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.
Attention
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.
