Program description - Tx. output swap
This option is available on the mc-20
HoTT transmitter only.
Use the selection keys of the left or right
four-way button to scroll to the »Tx. output
swap« menu option in the Multi-function menu:

Open this menu option with a tap on the centre SET
key of the right four-way button:

To ensure that receiver channel assignment is as flex-
ible as possible, the software includes the facility to
swap over any of transmitter outputs 1 to maximum
12 as a standard feature. This option lets you distrib-
ute the transmitter’s 8 or 12 “control channels” to any
of the transmitter outputs 1… 8 or 12. If you do, you
must remember that the »Servo display« screen – ac-
cessible from almost any menu option by simultane-
ously tapping the and keys on the left four-way
button – refers exclusively to the “control channels” as
preset by the receiver socket assignment: it therefore
does NOT take any output swaps into account.

Swapping the outputs on the transmitter
Programming procedure
Use the selection keys on the left or right four-way
button to select the channel/output combination to
be changed then briefly tap the centre SET key of the
right four-way button. You can now use the right selec-
tion keys to assign your selected (control) channel to
the desired output, confirming this with the SET key …

… or, by tapping the or selection keys on the
right four-way button at the same time (CLEAR), you
can restore the original assignment.
Any subsequent changes, such as servo travel adjust-
ments, Dual Rate / Expo, mixers etc., must always be
performed in accordance with the original receiv-
er socket assignment!
Example:
In the helicopter program of the
mc-16 HoTT and
mc-20 HoTT transmitters, the outputs for a collec-
tive pitch servo and the throttle servo are swapped
around, compared to some older GRAUPNER mc
units. The throttle servo now occupies transmitter
output “6” and the collective pitch servo output “1”.
Perhaps, however, you wish to retain the previous
conguration? In this case, you will swap over chan-
nels 1 and 6 as appropriate, so that (control) channel
6 is located on output 1 and vice versa – as shown
above:
Note:
“Channel Mapping” (channel assignment) is
the receiver-side channel correlation function
integrated into the mc-16 HoTT and
mc-20 HoTT transmitter’s telemetry menu. With
channel mapping, the transmitter’s control channels
(12 maximum) can be freely distributed to multiple
receivers or receiver outputs having the same control
function, for example to operate two servo controls
per aileron surface instead of just being able to
control one servo, etc. To keep controls manageable,
however, we strongly recommend using only one of
the options at a time.
