Here's what I do with this equipment -
7.5' Laser mesh w/ C and Ku single output LNB, polarotor type
DSR922
Coolsat 6000
PV high freq splitter dc block one side
4 port DiSEqC
V-box positioner
I split the C band signal, powerpass side to the 922, the other (power block) to port 1 of the DiSEqC.
I bring the Ku feed straight to the DiSEqC port 2 (I have another Perfect View splitter but I dont mess with DCII on Ku)
The CS satellite settings are configured for C=port1 Ku=port2. (The 2 extra DiSEqC ports are for future fixed dish inputs, that I need the RG6 re-run )
Currently the 922 controls polarity
and the V-Box controls dish position. (I tried suplementing the V-Box control using the DiSEqc 1.2 motor control feature from the CS, but was not able to get it to operate properly. Yes I know the V-Box needs to be before the dc block splitter. I will re-visit it when I have time.)
Using the 922 for both would mean I have to switch back to the 922 video to change dish position for DVB viewing/surfing. Since the 922 is for primarily for viewing, not surfing, it is little trouble to occasionally move to the desired sat when needed.
I have enabled and switch to satellite B6 in the 922 for polarotor fine tuning when using the DVB so I dont disturb the settings on any of the other DCII birds. I use B6 because it's map for channel polarity is direct, not reversed. Odd/even ch's on the 922 display = H/V polarotor positition respectively
The extra remote (V-Box) to manage is a bit of trouble initially, but you get used to it. A learning remote programmed with 4D and V-Box codes would be ideal.
The DiSEqC 'faults' occasionally (dont they all?) and I have to cycle the power on the CS to resync it, but other than that, the setup serves my purposes. Good luck with your ventures.
