well with my new dish1000+ and new VIP622. i want to use more cation in my tinkering. is there any thing i should avoid so i don't blow a switch or receiver up. i shut the power off when connecting switches. the receivers are on computer power/surge supplies. everything is grounded to the truck and electrical. so i guess I'm more concerned with connecting the power input in the wrong place or the power input of the DP44 into my pansat. or a bad combination of switches? any advice in these areas? thanks!
