Is there a 4 prong connection at EACH corner?
Did you check to see which ones were "hot" in the plug? Is one different than the others and male instead of female or vice versa?
If you have a small digital multimeter or 12 VDC test light you can check to see if you have power between the male which should be the ground lead and one of the female prongs. You can get a matching plug (or change these out) for the two lead plugs most jacks use now. Let me know what you find and we can go from there if you need more later. All follow ups are included in our fee. I don't think this has a "module board" as you say........that would come with the jack system.
Two is all you need here on each jack.............get back to me Tuesday if you need more here.
Were you able to get these wired up o.k.? Please get back to me if you need more help here. We can do a phone chat if you think that might be more helpful.
Did they come with a control module? You need that so it can receive the signal and activate the jacks on each line. You will still need to hook up each jack to the plug at each corner.
