VOS, first of all thanks for your contribution to this community. I have learned an awful lot in a short period of time particularly about SWM, DECA and MRV because of your input.
There appears to be two different SWiM setups:
1 - Ka/Ku Dish with single SWM connection to green label splitter to devices
2 - Ka/Ku Dish with four connections to SWM-8 or SWM-16 to devices or splitters then devices
If I have four devices that need to be connected to the dish, I can either use #1 with a four way green label splitter or I can use #2 utilizing a SWM-16 and use both SWM outputs with two way splitters. Assuming all else equal (cable lengths for runs to receivers), does #2 have an advantage over #1 because of the single splitter off of each SWM output? Or is there loss within the SWM-16 that makes this almost a wash?
Please correct me if I'm off base regarding anything I attempted to explain.
Second, I am going to be converting from a 3 DirecTivo setup to an HR-34 plus a pair of either C-31s or HR-24s. So I currently have a round dish (30" Winegard) with a dual LNB and multiswitch feeding the DirecTivos. I know that the dish has to change to one of the above two options. I am hung up on available tuners like others have been in this forum. In order not to chew up tuners in the HR-34, I would simply want the HR-24s for nothing more than the pause-rewind capability for live TV, which I don't think I can get with the C-31 unless I use a tuner on the HR-34. It hasn't been really clear to me if there is pause-rewind live TV capability on all of the C-31s connected to the HR-34.
Finally, If I go with either the C-31s or HR-24's, is it enough to just connect my home network to the HR-34 to get internet connectivity to everything?
OK let's start with the SWiMLNB verses the SWM8. They're the same, and the "old" SWM8 came out first for commercial use, followed by the SWiMLNB [cheaper] for home use.
1 coax carries 1 guide data channel [common to all receivers] and 8 channels for "tuners".
A non DVR has one tuner, while a DVR has two.
The C31 has "none", as it's merely a slave/client to the the server/HMC/Genie/HR34, which has 5 tuners.
The C31 has full DVR function since it is a client to the HR34, and for that matter can't function without it.
One SWiMLNB will feed: 1 HR34, 1 DVR, which leaves one channel free for a non DVR receiver. This same coax, could have another 3 C31s since they don't have tuners.
The SWiM-16 is based on two SWM8s in one package and why they have two coax outputs. Each of the SWiM "sections" are bridged together for the DECA/coax networking signal to pass between them.
The DECA/coax networking "merely" shares the same coax with the SWiM, but has no interaction with it.
"Splitters" are not switches like with the older systems, so you select them to have enough places to connect the coax your need, but never exceed 8 tuners.
"Sometimes" you need to split and then split again to fit the receivers and their locations. This can be done, but needs some attention to how as each time you split the power gets equally divided and if done wrong, one receiver may not have enough signal, while the other have more than they need.
