Transmitter control switch
It is often extremely desirable to switch a function on
or off automatically at a particular position of another
transmitter control, e.g. at a defi ned position of one of
the dual-axis sticks. Typical examples are switching a
stopwatch on and off to allow you to record the mo-
tor run time, lowering landing fl aps automatically, and
many others.
The program of the mc-22s includes a total of four
“switches” of this type. These software switches are
termed “G1 … G4”, and to use one all you have to do
is defi ne the trigger point along the travel of the trans-
mitter control; this is done simply by pressing a but-
ton. There are also “inverted switches”, which have
the same function but the reversed direction of effect.
They are therefore termed “G1i … G4i”.
Of course, control switches can also be combined
in any way with the external switches described pre-
viously; in this way many more complex problems can
be solved.
This manual includes a range of instructive examples
which make programming as simple as child’s play.
Please refer to the programming examples in the sec-
tion starting on page 72, 102 and 132.
Fixed switches: FXI and FX
This type of switch switches a function – such as a ti-
mer – on permanently (closed fi xed switch) or off per-
manently (open fi xed switch); alternatively it supplies
a fi xed input signal to a control function, e.g. FXI =
+100% and FX = -100%. For example, a fi xed switch
can be used in fl ight phase programming to switch a
servo or a speed controller between two settings. You
will fi nd another example on page 107.

Some of the transmitter cont-
rol inputs 5 … 12 are pre-as-
signed in the basic software
programming.
Transmitter control inputs 1 …
4 can be interchanged in the
»Base setup model« menu.
The above transmitter cont-
rols can be assigned to inputs
5 … 12 in any order.
