Port A came alive with 13/18 volts. Port B on the other hand took a few seconds.
Port A is always the switch startup default port.
A switch can have a slow startup time, and need a diseqc command repeat (or a longer pause, before the first command), for any other port than port A.
I don't see that a terminator could influence that; it is not near the controler IC, but at the other end of the ultimate (sometimes darlington) switching transistor.
Your (re)sources gave no explanation or cannot give an explanation, why this could be? I'm puzzled, to what exact problem cause these terminators are a solution.
It is nice that they work, but I'd like to understand..
