Transit Time (ms) - The time taken (in milliseconds) for the flipper to move from
position 1 to position 2 and vice versa, in the range 300 ms to 2800 ms.
The following parameters dictate the function of the SMA Digital I/O connectors on the
unit. They are identical for Digital I/O Pin 1 and Digital I/O Pin 2.
Operating Mode - This parameter specifies the operating mode
Input:Toggle Position - Sets IO connector to input and 'toggle position' mode. In this
mode, the input signal causes flipper to move to opposite position).
Input: Goto Position - Sets IO conn ector to i nput and 'goto position' mode. In thi s
mode, the input signal dictates flipper position, POS 1 or POS 2 as dictated by the
Button Input or Button Input (Swap Pos) parameters described below. See Fig. 3.2 for
details of POS 1 and POS 2.
Output: At Position - Sets IO conn ector to output mode, where the O/P signal
indicates the flipper is 'at position'.
Output: InMotion - Sets IO connector to output mode, where the O/P signal indicates
the flipper is in motion (i.e. between positions).
Digital Signal Mode - Th is parameter specifies the functionality of the inpu t/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 Pos.) - 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: Goto 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 Pos.) - As above but the logic transition (edge) 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 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: InMotion, 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.
