Function switches
The functions switches are a type of multipos switches that are managed directly by OpenTX. Physicaly, they look like a regular 6pos switch, but they are much more flexible.
Unlike other switches that are manage at radio level, functions switches are defined per model, and are therefore set in model setup page.
Function switch can be set to:
'none' : they are basicaly disabled
'toggle' : they are active only during push duration
'2POS' : pushing the switch will altenate state : OFF push ON push OFF ....
A traditionnal 6POS is basicaly a group of 6 switches that work together, where only one can be active at one time. Functions switches expand that concept and let you choose how FS should be grouped.
'-' defines a function switch with no group. Pushing it will only affect this switch
'1', '2' or '3' define groups. All the switches in a group act together, where only one (the last pushed) can be active
Always on groups : in hardware 6POS implementations, one switch of the group MUST stay on, in other words, the switches in the group cannot be all off. If you want this type of behavior, you should tick the check box at the right side of the screen.
In a tradional 6POS , all the switch belong to the same group. If you want 2 groups of 3 switches, assign 3 switches to group 1, and 3 to group 2
You can defined in what state each switches will be when the model is loaded
'↑' switch is inactive
'↓" switch is active
'=' switch is set to the same state is was when the model was last used (it keeps old state)
Unlike hardware 6POS implementation (Horus, TX16S,...), those software managed switch can not be used as an analog source, they are individual switches with either ↑ or ↓ position. The behavior of previous 6P source can be achieved using a combination of mixer lines
