Output: At Position - Sets IO connector to output mode, where the O/P signal
indicates the flipper is 'at position'.
Output: In Motion - Sets IO connector to output mode, where the O/P signal indicates
the flipper is in motion (i.e. between positions).
Input Signal Mode - This parameter specifies the functionality of the input/output
signal.
Button Input - The connector can be short circuited (e.g. with button). If the Operating
Mode above is set to Input:Toggle Position then a short circuit causes the flipper to
toggle position. If the Operating Mode is set to Input: Goto Position then a short circuit
causes the flipper to move to POS 1 and open circuit causes flipper to move to POS 2.
Button Input (Swap Position.) - As above but the open circuit and short circuit
functionality is swapped when operating in Input: Goto Position mode. If operating in
Input:Toggle Position mode, the functionality swap has no effect and the position
toggles in the same way.
Logic Edge Input - The connector is set to logic input where a logic transition (edge)
dictates flipper operation. If the Operating Mode above set to Input:Toggle Position,
then a LO to HI edge causes flipper to toggle position. If the Operating Mode is set to
Input: Go to Position, then a LO to HI edge causes the flipper to move to POS 1 and
a HI to LO edge causes the flipper to move to POS 2.
Logic Edge Input (Swap Position.) - As above but the logic transition (edge)
functionality is swapped when operating in Input: Go to Position mode. If operating in
Input:Toggle Position mode, the functionality swap has no effect and the position
toggles in the same way.
Logic Level Output - The connector is set to a logic output where the logic transition
(edge) represents flipper position. If the Operating Mode above is set to Output: At
Position, then a LO to HI edge (HI level) indicates flipper is at POS 1 and a HI to LO
edge (LO level) indicates the flipper is at POS 2. If the Operating Mode above is set
to Output: In Motion, then a LO to HI edge (HI level) indicates the flipper is moving
between positions and a HI to LO edge (LO level) indicates the flipper has stopped
moving.
Logic Level Output (Inverted) - As above but the edge transition (level) functionality is
swapped.
Logic Pulse Output - The connector is set to a logic output where a logic pulse
indicates flipper operation. If the Operating Mode above is set to Output: At Position,
then a logic HI pulse indicates flipper has reached a position. If the Operating Mode
above is set to Output: In Motion, then a logic HI pulse indicates the flipper has started
moving. The Pulse width is set in the Signal Width paramter below.
Logic Pulse Output (Inverted) - As above but the pulse functionality is swapped.
