I am helping a friend in initial setup of Viewsat Ultra. There are Dish 500 and Superdish with DPP and DP LNBs passing thru SW44 in the present configuration. Also, there is subscription with DN with 2 dual receivers. The subscription is going to remain active while Viewsat ultra is going to be added. Can somebody suggest me a link that has details discussed on this topic or kindly list steps on this. Thanks
