Question: How do I set (and read) the DIP switch settings on the boards in my DFE controller products?
Answer: Switch blocks all work the same: There are numbers running down one side and there is a line with the word "OPEN" on the other side. If a switch is pushed in on the numbered side, this means that switch is closed. If pushed in on the side reading "OPEN", the switch is open.
The switch should be actuated by something with a point, such as a ball point pen, for proper closure (or change of setting) of the switch.
