Definition of terms
Control function
A control function is the signal for a specific control function. The
signal of a control function can be transmitted directly into one con-
trol channel or through a mixer to several control channels. The con-
trol function includes the influence of the mechanical control path
on the corresponding servo. This can be spread or concentrated and
modified from linear to highly exponential.
Controls
A "control" is the function element that the pilot can operate directly
in the transmitter. The controls connected to the servos, ESC etc. will
be controlled by the receiver.
Control channel
The term control channel is used if a signal contains all control infor-
mation necessary for a particular servo , directly from the control or
indirectly via a mixer.
Mixer
The transmitter software contains a variety of mixing functions.
These allow a control function to influence several control channels
and several servos. Several control function can influence control
channel (one servo).
Switch
The series of toggle switches can be included in the control program-
ming. The switches are generally intended to switch program options
such as to start and stop the timers, turn mixers on and off, etc. Each
switche can be assigned any number of functions.
Control switch
In these software switches, labelled with "G1 ... G8", the switching
point within the control travel can be set by simply pushing a button.
Logical switch
Two switches, controls and logical switches or the combination of
the three can be interconnected in an "AND" or "OR" switch. A total
amount of 8 logical switches "L1 … L8" can be programmed.
Fix switch FXI and FX
This kind of switch always turns a function on or off. You can also
assign to a control function a fix input signal, e.g. FX = +100 % and
FXi = -100 %.
