3) From the GUI panel of the Slave unit, click the Settings button to display the
settings panel.
4) Make parameter settings as follows:
Digital I/O Pin 1
Operating Mode: Input: Toggle Position
Digital Signal Mode: Logic Edge Input
These settings set the Slave unit to flip the optic position, each time a Logic High
(5V) Edge is received on DIG I/O 1.
Digital I/O Pin 2
In the two unit master slave configuration, these settings are not used, though it is
recommended that the DIG I/O Pin 2 Operating Mode be set to an Output option
to avoid accidental triggering of the flip action.
5) Connect the DIG I/O Pin 2 terminal on the Master unit to the DIG I/O Pin 1 terminal
on the slave unit.
