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
Input 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.

5.3 Using the Software Commands

In software, the filter flipper is moved using a motor 'Move/Jog' method. This method
contains a parameter to specify the direction of the move, '1' for clockwise and '2' for
counterclockwise.
To read the flipper position, the motor 'Get Status Bits function is used. If bit1 is set to
1, the flipper is in the upright position, if bit 1 is set to 0, the flipper is horizontal.
See the Server API helpfile for more details on the use of these functions.
