Hey have a question about icecap 660

[duecy4u]

Hey guys I have an icecap 660 the older. I was wondering what the four pins for and how do you use them

It is an I/O port. You can use it to dim if you want. I do not know of anybody who ever used it.

Great is it like 2 io port channels?

I have no idea how it works since I never did it.

I ran Icecaps years ago, and back then, was told that only T12's could be dimmed. Not sure of the truth of that. Not sure if he's been around here much, but @twilliard use to rebuild/repair these ballasts, and most likely would know the answer to your question.
