I have a Zinwell MS3X4WB-Z multiswitch and it seems to have some quirks to it. I tried running a cable from the 2nd output on it and was unable to get a signal out of it while using the 1st output. MY openbox also doesn't seem to read signal out of both inputs. I am not sure how to switch this. I have a cable to my receiver from a 4 port diseqc switch. The multiswitch is hooked up to port 3 on the diseqc switch. The multiswitch is also hooked up to my 10 foot and 13 foot dishes.
