Receiving system
The
mx
-16ifs radio control set includes an XR-16ifs 2.4
GHz bi-directional receiver which is suitable for connec-
tion to a maximum of eight servos.
When you switch the receiver on, its Status LED initially
glows constantly for about three seconds, and then
starts
fl ashing red . The latter means that no connection
with a Graupner | iFS RF module exists (at this stage).
To be able to create a connection, the Graupner | iFS
receiver must fi rst be “bound” to “its” Graupner | iFS RF
module (transmitter); this procedure is known as “bind-
ing”. However, binding is only necessary once for each
receiver / RF module combination (and can be repeated
whenever you wish – for instance, if you change the
transmitter). The components in your system have
already been bound at the factory.
The set you have purchased implements iFS Version
3, which differentiates between primary, subsidiary and
supplementary receivers:
At the “Binding” stage – see below – receivers defi ned
as primary units can only be operated separately with
a
Graupner | iFS RF module. This eliminates the danger
that a (primary) receiver in another model might respond
to the same transmitter signal when it is switched on.
At the “Binding” stage – see below – receivers defi ned
as subsidiary units are operated in “Slave mode”, and
are subordinate to the primary (“Master”) receiver.
Subsidiary receivers can therefore be operated in paral-
lel with primary receivers. They are intended primarily
for use in large model aircraft, with the aim of avoiding
long cable connections to the control surface servos,
and the associated losses. A separate power supply can
be used to prevent further unnecessary voltage drop.
However, subsidiary receivers can also be employed at
completely different locations from the model, e. g. as
monitor receivers on the ground.
The use of multiple receivers can also make sense in
large model boats such as the Seabex One; with models
such as the Adolph Bermpohl, Theodor Heuss or Bern-
hard Gruben ocean-going rescue cruisers the subsidiary
receiver can be used to control the ship’s boat using one
and the same transmitter.
The purpose of supplementary receivers (Order No.
23608 , see Appendix) is quite different to that of sub-
sidiary receivers: it is to enhance safety. For example,
installing two supplementary receivers in the wingtips
and another in the fi n ensures that visual contact is
maintained virtually constantly, with the result that at
least one receiver can pick up the transmitter signal in
any fl ight attitude.
Note:
The “programming button” referred to in the following
sections is located on the circuit board, and can be
operated using a blunt instrument such as a 1.5 mm
allen key.
PLEASE DO NOT USE A SCREWDRIVER
to push the button, as the risk of damaging the circuit
board is too great.
“Binding” the Graupner | iFS receiver
Graupner | iFS receivers must be “instructed” to commu-
nicate exclusively with a single Graupner | iFS RF module
(transmitter). This procedure is termed “Binding”, and is
only required
once for each new receiver.
During this procedure any other Graupner | iFS main
receiver MUST be switched off BEFORE you switch
the transmitter on.
Now switch the Graupner | iFS receiver on, and wait until
the status LED fl ashes red . Hold the programming button
on the receiver pressed in until its LED lights up green .
Now release the programming button, and the Status
LED will
fl ash orange , indicating that the receiver is now
waiting for a Graupner | iFS transmitter to initiate the
“binding” process.
At the transmitter end
Locate the Graupner | iFS RF module’s programming
button on the back of the transmitter, and hold it pressed
it while you switch the transmitter on. Hold the button
pressed in while the Status LED fi rst goes out, and then
glows green , then release the programming button.
As soon as you release the programming button, the
transmitter and receiver should bind together: all the
Status LEDs will simultaneously switch to
green if the
binding process has been completed successfully. If one
Status LED
does not light up green, repeat the whole
procedure.
Binding subsidiary receivers
In Hopping Modes 2 … 5 any number of subsidiary re-
ceivers can be bound in common with a (single) primary
receiver. (In contrast, multi-receiver operation is NOT
possible with Hopping Mode 1.)

switched off , switch your subsidiary
