625 receiver is not working with DPP Separator on one line, presumably because I am running the signal line from a DP QUAD LNBF. I do have an open LNBF port on my dish, but do not want to run another line to the receiver. My question is, will installing a DPP 33 switch with the DP QUAD followed by the DPP Separator allow me to use just one signal line? And, can I just use the switch on the one line right at the receiver, or do I have to connect all three signal lines from the LNBF through the DPP 33? Any input greatly appreciated! Other two receivers are DP Solo 301's and working fine.
