Hi Could you tell me what passive would replace this one as it has 3 extra connections to the normal 6. These are marked C+ , E- , and FTA. There is a wire looped from the power minus connection to the FTA connection and a brown wire in the cable connected to the C+ connection. What is the purpose of these extra connections ? The reason for replacement is that this passive leaves the led indicator on permanently which doesn't seem correct. I have always used risco quads in my own setup and they seem very reliable. Would one of these fit the bill ? The panel is a Scantronic 9800. Hoping someone can point me in the right direction for a replacement. Thanks in advance Kevin
