My parents have an HR23, R15, and an old RCA SD receiver. All are connected to an SL5 SlimLine dish, with 4xRG6 running to a WB6x8 multiswitch. Two RG6 wires to each DVR, one to the RCA. It works with no problems whatsoever.
They want to get a Genie for their main viewing room, and move the HR23 to another bedroom. They don’t really care to swap out the old SD receivers at this point, since they are comfortable with how they work and both units are old enough that they are owned anyway.
So, as a first step to prepare them for Genie, I swapped the multiswitch for a SWM16 module. I chose the SWM16 mainly because of the legacy ports it provides in addition to the necessary SWM capability. A SWM8 module would have also worked, but I figured the SWM16 would provide some future protection in case they ever want another DVR (or even a second Genie if DirecTV allows it someday), any of which would put them over 8 tuners. Got it “new” on eBay, although it was a couple of months ago and has taken me that long to get around to installing it.
I connected the four sat feeds to the bottom of the SWM16 and connected the three legacy runs to three of the legacy ports on the top left side of the SWM16 (2 to R15, 1 to RCA). I connected a PI-29 inline between the HR23’s SAT1 input and the SWM1 output of the SWM16, disconnecting the SAT2 input from the HR23 in the process. The PI-29 sits inside the house behind the TV. It is probably less than 40 feet from the TV to the SWM16 on the side of the house, and the RG6 is solid copper. (It is probably ~100 feet between the SWM16 and SlimLine dish due to trees near the house).
The SWM16 ran extremely warm within a few minutes after I powered it up. I would say pretty hot, actually. While it seemed hotter than it should be to me, it didn’t seem to be all that unusual based on what I read here on DBStalk, so I tried to temper my concern.
Next, I booted the HR23. At first, it seemed to be doing fine, going automatically through startup, Step 1 of 2, Step 2 of 2, etc. It got subsequently stuck at the Acquiring Guide Data step (but no channel/picture yet). The More Info button just said to RBR or reboot (I forget which) if it took longer than two minutes, which it did. So I RBR’ed, and rebooted a few times, and nothing changed. I checked all the connections to the SWM16. Finally I just tried to hit the Menu button on the remote when it said Acquiring Guide Data, which to my surprise, allowed me access to a limited menu where I could step through the Satellite setup and it completed with no problem and a channel started playing immediately. In the settings it said it had detected the SWM and everything seemed ok.
Later, there was a problem with channel 231, Food Network. I checked the signal strengths using the HR23. The 101 transponders looked fine (2 transponders show 0, everything else pretty strong). Similarly on all other satellites, everything looked normal to me except for the 103ca and 103cb, where all the odd transponders were 0 on both tuners (evens looked great—all in 90’s). Channel 230 looked fine. These are the HD versions. I think 231 HD comes over the 103 sat, although I’m not sure which transponder (I am betting one of the odd ones!)
After seeing this, I thought maybe something was wrong with the 103 input on the SWM16, or possibly the 103 part of the LNB (but the latter seemed unlikely, really, given that it was all working previously).
Then I booted the R15. It also seemed fine at first, but later there would be messages like Searching for signal on Satellite In 1 & 2 (771) flashes for a few seconds on the screen, then disappear. Some pixellation occurred as well. The R15 signal strengths showed a bunch of 0 strength transponders on 101 (10-12 of them). Tuner 2 showed a large number of zeroes on 101 as well, but on different transponders than Tuner1 !! This, combined with the good 101 readings from the HR23, implies to me that it is not an issue with the 101 signal getting to the SWM16 unit…
I didn’t bother to check the RCA at this point.
BTW, I assume the SWM16’s SWM2 output doesn’t require that something be connected to it, receiver-wise, at all times. Not sure if that is a good assumption. Until they get the Genie, I had initially just moved one of the legacy port caps to cover it up. When I ran into problems later, I actually put a terminator on it that I got from an unused SWM splitter I have, but it didn’t seem to change anything.
Questions for discussion (of course, feel free to add your own!):
1) Between the heat, the 103 odd transponder issues, and the different 101 readings, I think this SWM16 is defective. Does this sound like the right conclusion? Or, are these symptoms indicative of some other problem?
2) Is there anything about the way I did this that might have led to extra heat or problems (like driving three legacy outputs, or not connecting the SWM2 output, etc.).
3) Do the SWM8 modules run as hot as the SWM16? I guess I could “downgrade” to a SWM8 if there is an advantage to doing so, although I’m not sure what that would be.
