Tx. output swap

Swapping the outputs on the transmitter
Using the arrow keys on the left or right touch pad, page
to the menu option "Tx. output swap" on the multi-

open this menu option.
Tx. output swap
To achieve maximum fl exibility regarding receiver socket
assignment, the mx-20 HoTT program offers you the
option of swapping servo outputs 1 to 12 as you please.
This option lets you distribute the transmitter's 12
"control channels" to any of the transmitter outputs 1
... 12. If you do, you must remember that the "Servo
display" screen – accessible from almost any menu
option by simultaneously tapping the  and  keys
on the left touch pad – refers exclusively to the "control
channels" as preset by the receiver socket assignment:
it therefore does NOT take any output swaps into
account.

Use the arrow keys  on the left or right touch pad to
select the channel/output combination that you wish to
change and then briefl y tap the center
right touch pad. You can now use the right arrow keys
to assign your selected (control) channel to the desired
output, confi rming this with the SET key ...

... or, by tapping the arrow keys  or  on the
right touch pad at the same time (CLEAR), you can
restore the original assignment.
Any subsequent changes, such as servo travel
adjustments, Dual Rate / Expo, mixers etc., must
always be performed in accordance with the original
receiver socket assignment!
Example:
In the mx-20 HoTT helicopter program, the outputs
for a collective pitch servo and the throttle servo are
swapped around, compared to some older GRAUPNER/
JR 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
confi guration? In this case, you will swap over channels
1 and 6 as appropriate, so that (control) channel 6 is
1
located on output 1 and vice versa – as shown above:

The "Channel Mapping" (channel assignment) function
integrated into the telemetry menu on the
mx-20HoTT receiver can also be used to distribute up
to 12 control channels from the transmitter to multiple
receivers. The function can also be used to map the
SET key on the
exact same control function to multiple receiver outputs:
this can be used to confi gure two servo controls per
aileron surface instead of just the one, for example, etc.
To keep controls manageable, however, we strongly
recommend using only one of the options at a time.
