5.2.2 Master/Slave Operation
If required, two flipper units can be wired in a master/slave configuration, such that a
demanded flip on one unit, also triggers the other unit to flip.
1) From the GUI panel of the Master unit, click the Settings button to display the
settings panel.
2) Make parameter settings as follows:
Digital I/O Pin 1
Operating Mode: Input: Toggle Position
Input Signal Mode: Button Input
These settings set the Master unit to flip the optic position, each time the button is
pressed.
Digital I/O Pin 2
Operating Mode: Output: In Motion
Output Signal Mode: Logic Level Output
These settings set the Master unit to output a logic high signal on DIG I/O 2 while
the flipper is in motion.
