    Snif snif; Sad to report that the code to power the DECA for the H23/600 appears to have not been included in this CE release! :mad::nono2::nono::eek2::confused::(

    Very interesting problem resolved.

    Had recently removed the DECA's, since each receiver had hard-wire ethernet, but left the DECA filter on the line (for future DECA use).

    Been noticing a weird problem on one of the H21-200's, intermittent "searching for signal". Thought it was related to recent CE, or maybe that the RG-6 to the receiver looked slightly crimped.

    Had some time today to finally diagnose the problem, and problem solved.

    Tried several scenarios, nothing fixed the problem ... until I removed the DECA filter. Every test has now passed.

    Seems like you don't want the DECA filter on a line with no DECA's. I guess I should have known this but figured it wouldn't hurt.

    That would make alot of sense, as filtering just a certain frequency range without the DECA's would only open up the potential for issues...while it would add no value otherwise.

    H21-200 only had the issue. HR21-200 was fine. But now that I think about it, the HR21-200 has been quirky lately, I need to test the HR21-200 now ... Hmmm.

    I guess the bottom line is without the DECA's....a filter is of no value and only the potential for other things being messed up.

    Once we get the new units...we'll have all that stuff hooked up again anyway.

    :confused:
    This makes zero sense.
    The filter notches out [about] 500-600 MHz.
    I've got my filter mounted at my first splitter now.
    Three DVRs have DECAs + one for the ISP connection.
    This leaves my H21-200 connected off the SWM, down stream of the filter, with no DECA.

    Agreed, unless his filter has a faulty connector.

    Agree, but as soon as I removed the filter, the problem went away.

    SWM-8. Port#1 had filter, to 2 way split, to H21-200 #1 and HR21-200. Port#2 directly to H21-200 #2.

    All three units are on the latest CE.

    H21-200 #1 failed a system test, and could not hold a signal (while in the signal meter).

    Just re-added the filter, and all is fine. :confused:

    Thought I had nailed the exact cause. Now not so sure.

    Thanks for all the feedback here.

    Not to worry....when we get the new toys....likely we'll see all sorts of new behavior....:D

    Tick tock, tick tock.

    Maybe this will be the week for DECA II. :)

    Above all...would love to see VOS all green. :D

    I could start drinking right now if you want. I'm sure that color wouldn't take that long.

    I had DECA set up on two HR22-100's and an H21-200.

    A few days ago, I shuffled my equipment around quite extensively in order to put DVRs with larger hard drives in the locations that needed the most recording capacity. I left the DECA units at the original locations, so they ended up on different devices. After the shuffle, I had DECA set up on an HR21-200, an HR20-700, and the H21-200.

    Tonight, due to recurring and frustrating MRV issues, I decided to shuffle the DECA units around and put them in the locations that seemed to be most problematic for MRV. Two of those locations had small 5 port ethernet switches to take a single ethernet feed to the room and run multiple devices (including the DVR) off of it. So I put the DECA units where the switches were so as to not use the switches to supply network to the DVRs. End configuration is DECA on two HR22-100's, and an HR20-700.

    (The fourth DECA module all along has been connected as the network port to the outside LAN/WAN.)

    After making all the changes (which also included changing the H21 from SWM to multiswitch, and one of the HR22's from multiswitch to SWM), everything is back up and running, with network functionality at all locations (which I had all along), and MRV not working anyplace.

    Oh well. Seems I'm not the only person with MRV problems this week.

    Not sure there is really a "DECA Issue" in all of this, but definately felt that putting DECA where the MRV problems were (and thus eliminating the small ethernet switches) was worth trying, and was dissapointed it did not make a difference.

    As I think everyone here is aware, it is no problem switching from DECA to non-DECA and vice-versa. It is a pain in the posterior switching from SWM to multiswitch (or the reverse), requiring resets and going back through sat setup.

    Carl:
    Pretty sure your problems are not related to DECA. I've made no changes to my DECA setup and have similar MRV problems with the latest CE.

    Likewise...the problems are in this CE series, not DECA.

    You are not at all alone on this...

    Diagnostic Code: 20091113-DDE

    No Code to enable DECA on H23-600.
    2 CE's ago the code was there and the DECA was working off of power supplied by the H23. These last 2 CE's do not appear to have the code and the DECA has no lights after booting up the H23.

    Also posted in the H23 Issues forum.

    Hmmmm...my H21-100 is working fine with the DECA unit there, as it has for some time (except the last CE MRV issue everyone else reported).

    If you have no lights there at all...suggest you reset the entire DECA/SWM setup, and see if it all comes back up.

    If the lights remain "out" after that - it could be the unit is failing for some reason.

    The good news is that we're going into the "DECA 2" testing phase soon, so we'll all have new units with newer firmware anyway.

    Last night during the download, my HR21 DECA "went dark", which isn't the point, but what is was the fact that all other DECAs went GREEN.
    3 DECAs going through short coax runs to a 4-way splitter seem to be causing all DECAs to have yellow C.Lnks, and 2 DECAs on the 4-way don't.
    Have I mentioned this could be an RF problem before? :lol:

    Sounds familiar. :D

    Glad to see more "green" in your DECA life these days. ;)
