Since we can diplex OTA, can we do the same with cable?
i believe there was someone on here diplexing cable instead of OTA. I know I saw it in this 29 page thread somewhere.
Would conneting an SWM enabled cable to an HR20 with a BBC (only temporarilly) cause damage to anything? I assume some (new HD)channels might not come in when connected this way but would it hurt anything. Reason: I don't want to pull all my stuff out of the ent center to rewire so I'm considering doing it blind, by touch / trial and error. Note: PI would already be handled.
Interested in buying a SWM8, but have a few questions that are probably frequently asked. Is there a FAQ for ordering one from you Dave? This thread is getting quite dense to navigate.
just pm me and i will try to answer whatever you need to know
Yeah, I have it diplexed on the HR20 (sorry about the ambiguous terminology).
I have my OTA set up to split between my OTA feed on the SWM and diplexed into my legacy line for my HR10-250. I don't have another diplexer, yet, so I am using a 2GHz splitter at the HR10-250, temporarily, and it seems to have good signals.
I haven't followed this thread in a while but had one comment. I've seen it recommended that you need to reboot the receivers after connecting to the SWM. If I recall correctly, the recommended way is to power off the receivers, connect to SWM, power to SWM, then power to receivers. That may be what is causing some of the error messages some folks are getting when they first connect.
With respect to OTA, is the built-in diplexer in the SWM good enough or would it be better to put one of the highly rated ones on the output line to the receivers? I remember some discussion about this earlier but don't know if it was ever answered.
I have the same question: to use the SWM-8 for diplexing or the 4002IFD's? Also, my second SWM-8 from Dave came REALLY fast! Woot!
ok.. one more question.
I can understand why the power inserter cannot get wt, but can it be outdoors if there's no chance of geting direct contact to water? I have a TV/VCR/D11 receiver outside on my enclosed screen room now. I'm thinking for 60, I can get a D12 and use the line I am burning for that TV and install the power inserter there.
biggest thing is it is vented.. the board is clearly veiwable thru the slots.. but if you can get away with a reciever out there I would expect the PI to be fine too..
Finally got a chance to install my SWM-8 - works a treat! Just had to reboot to get it to be seen (already had it powered). This enabled me to put my OTA antenna back in the mix as I have only four lines into the house. Now I have two legacy lines for the HR10, one for SWM and one for antenna.
Either way. You can use the 402IFDs as the splitting diplexer if you use the SWM8's OTA input. There is no difference. ( I have tried both )
hmm.. having probs getting my cable to dples through the OTA. What am I missing here?
I have a diplexer splitting the line back at the TV with the sat going into the dish and the cable going into the TV, but get no signal. When I do that, the SAT gets no signal. If I split the line with a power pass splitter I get SAT signal just fine, but still not Cable. thoughts?
i hope someone else has an answer for you as i dont know much about diplexing cable(i.e bandwith ect.)
i know a couple other members have diplexed cable, i have only done ota
I seem to remember that cable shares some frequencies with the satellite channels. I don't think it will work. Ask VOS or one of the more technical members for a definitive answer.
Cable doesn't use much [any] frequencies over 900 MHz.
It may seem dumb, but my first thought is the diplexer is backwards or defective.
The SAT signal should come through the diplexer in either direction, so drop the cable to the SWM and work with the diplexer until you get the SAT feed through it. After you can prove it functions then add your cable to the SWM and work on it as "it should work".
Considering the SWM8 to cleanup some of my cabling mess, but have a couple of questions that I haven't found the answers to in the various SWM threads...
Does it matter which output from the dish is connected to the SWM inputs, or do they need to as labeled on the SWM (voltages and tones)?
If I split the dish output before the SWM to run both a SWM and a standard multiswitch, again does it matter which cables go where (same voltage/tone input on the SWM8 and the multiswitch from one splitter)?
The SWM8 supports 8 SWM tuners and 3 legacy tuners concurrently (ie: you could have 11 tuners total)?
OTA input is not diplexed for the legacy ports, correct?
The PI can be connected to either FTM1 or Legacy3?
If Legacy3, can this port also be used for a legacy tuner (connected to the IRD output of the PI)?
1) No it does not matter what input you connect the lines from the dish to as long as all 4 are connected.
2) If you are doing a parallel setup it does not matter after the splitter what input you connect them to as long as both outputs on the splitter goes to the same input on the SWM and MS.
3) Yes it would be able to control 11 tuners but the legacy outputs will not be able to do the MPEG4 HD channels.
4) I don't remember if you can diplexe OTA on the legacy outputs or not. Hopefully someone else will be able to help here.
5) Yes it can be connected to FTM1. I did see a post the other day saying it could be connected to Legacy 3 but I am not sure if that is true or not.
6) Not sure
1. Doesn't matter, but see #2
2. Now it matters. When spitting pre switch, you must match up the spit lines. Both lines from spitter one need to go to the same input on the switches, ex 18v. Same for the second spit line, both to the 13v port, and so on.
4. Correct again (I think )
5. Yes, but FTM1 is recommended
6. Maybe, but I wouldn't try it for fear of frying a box.
No MPEG4 is understood on the legacy ports. Thanks for confirming my thoughts on the other items. I'll be interested to hear what others say about PI on the Legacy3 port. I've seen this in some diagrams on the web, but haven't seen any confirmation of it here. For simplicity, I'll probably do FTM1 - PI - Terminator and FTM2 - 4way splitter - each of 4 receivers.
ps - Thanks for the REALLY fast replies!
