Hi guys...I have the dish 500. It is hooked up to a dish switch DP34. To that are hooked a 322 and a 522. I want to add another 322. I have an extra DP34 switch. On the right side of the DP34 it says "To additional switch". Since there is no place to hook the third reciever on the DP34...can I connect the extra DP34 I have to the "additional switch plug", then plug the third reciever into it and it work...or am I way off base. What additional hardware would I need for this set-up to work? If it will work at all. Thanks in advance! mike
