I have several Extron and Kramer boxes that just need a simple contact closeure made in order to switch from one input to another (e.g. when 1 and common are connected it uses input 1, when 2 and common are connected it uses imput 2. If the connection is open you can select imputs via the box's facepanel switches.)
I have read the article in the Wiki, but the diagram doesn't make any sense to me. How can I create a cable that connects to the Ion with a DB15 connector that will allow me to connect to the simple terminal screws on an Extron or Kramer box?
Thanks!
