General information about programmable mixers
This manual has described numerous preprogrammed
coupling functions. The basic meaning of mixers and
their functions are explained on the page to the left. The
following offers information on "programmable mixers".
In addition to the aforementioned preprogrammed
mixers, the mz-18 HoTT and mz-20 HoTT transmitters
offer five freely programmable linear mixers and three
curve mixers in each of the 30 model memories per
programmed Quick Link in which you can define inputs
and outputs as well as the degree of desired mixing.
This maximum of 48 mixers per model memory should
be sufficient, and is in particular for taking advantage of
the options of pre-programmed coupling functions.
The input signal for a control function (1 ... 9 and
1 ... 12) is used as the input signal for programmable
mixers. The signal that is on the control channel and
supplied to the mixer input is always influenced by
its control element and its set characteristic that for
example is specified by settings in the "D/R,EXP",
"THR.CRV" and "CH.Set" menus.
The mixer output acts on a freely-selectable control
channel (1 to a maximum of 12 depending on the
transmitter and receiver) which, before it sends the
signal to the servo, can only be influenced by the
functions Reverse, Sub-Trim, Travel and E.P.A, and
possibly the option "(Transmitter) output swap".
One control function, page 37, may be used simulta-
neously for any number of mixer inputs when for exam-
ple you want mixers to be parallel-connected.
Conversely, any number of mixer outputs can affect one
and the same control channel, page 37. Particularly
in the latter case, however, you should make sure that
the affected servo does not reach its mechanical limit
when several mixing signals combine into one which is
too large. To be safe, a corresponding travel limit should
therefore be set in the "E.P.A" menu, page 66.
In the program, a programmable mixer is initially always
blocked (
) and therefore needs to be explicitly
INH
switched on while programming it. Optionally, the mixer
can also be assigned an ON/OFF switch. Given the
numerous switchable functions, make sure that you do
not unintentionally assign a switch two functions.
The two essential parameters of the mixers are ...
•
... the degree of mixing that determines the level of
influence of the input signal on the control channel
connected to the mixer output.
With linear mixers, the mixing level can be adjusted
symmetrically or asymmetrically. With curve mixers,
the mixing level can also be configured according to
your own specifications by up to 7 points to produce
extremely nonlinear curves.
•
... the neutral point of a linear mixer, also termed
the offset.
The offset is the point along the travel of a control
element (control stick, proportional control or switch)
at which the mixer no longer influences the control
channel connected to its output. Normally, this is the
middle position of the control. The offset can also be
located at any other position along the servo travel.
Since curve mixers can be configured as desired,
it is only recommendable and possible to specify a
mixer neutral point for the 5 linear mixers.
