Hello everyone,

I'm looking to control this DC Iris lens and have developed the software to control it, but am having trouble figuring out what types of voltages I need to apply to the control and drive pins to control it properly. I want the aperture size to increase and decrease slowly in increments. I've run both coils between 0 and 3 V, separately and simultaneously, but the aperture always seems to go from completely closed to completely open at a particular voltage. I am not looking to buy a controller as I have already developed it.

Any help would be very appreciated.

Hello Ceez, and welcome to the freindly Camera Labs forum!
Unfortunately I have no idea of what you're talking about.
So it might be advisable to dig a little deeper into what you're trying to accomplish if you're looking to get any help from the forum members here.
