Operating the transmitter
PROFI TX
MagicSwitch
The PROFI TX features 4 MagicSwitches.
A MagicSwitch is a logical switch which can be assigned to a switched or control
like a real control.
It combines up to 4 switches (including other MagicSwitches and flight phases).
The first switches are combined by AND: The output of the MagicSwitch is only
switched to "On" when all of the switches are ON. Unused inputs are considered
switched on.
The 4th switch is combined in an OR function with the result of the AND group.
If this switch is "ON" or the AND group is "ON", the MagicSwitch is "ON". When
no switch is assigned, this input is considered to be switched off.
The MagicSwitch is switched on when all switches of the AND group that are
assigned to it OR the 4th switch are switched on.
The MagicSwitch output switches with a configurable delay. OFF and ON delays
can be configured separately.
Switches are assigned in the Setup > Assign.Switches > MagicSwitch menu
(see page 108).
To assign a MagicSwitch proceed as follows:
1. Move the input cursor to a switch.
2. Open the desired input field next to it.
3. Assign the desired switch using the central wheel or by operating the switch.
The switches MS1, MS2 (MagicSwitch) and FP1 to FP4 (flight phases) cannot
be assigned by operating a switch.
4. Set the switch to the ON position or select the ON position using the REV/CLR
button.
5. Close the input field.
