    SWM Troubleshooting guidelines:

    Current SWM compatible receivers:

    HR23-700
    HR20-700
    HR20-100
    HR21-700
    HR21-200
    HR21-100
    H20-100
    H20-600
    H21-100
    H21-200
    H23-600
    R22-100
    R22-200
    D12's

    Troubleshooting Guidelines:

    *---- Log satellite transponders/strength signal readings
    *---- Log SWM signal strength
    *---- Check & verify that "all BBC's" are removed from all SWM receivers
    *---- Check & Verify on the power inserter (PI) that the green LED is on through vent slot.
    *---- Check & Verify SWM signal strength.
    *---- Check & verify that all connections are tight
    *---- Check & verify on the PI that red FTM output goes to the SWM
    *---- Check & verify that coax distance don’t exceed 60' from the dish to the SWM
    *---- Check & verify that the min distance for the coax for the pi is no shorter than 15'
    *---- Check & verify that the splitters pass power on only one leg, If using splitters and more than one SWM
    *---- Check & verify if only SWM port is used, the 2nd SWM port has a terminator cap installed


    Tips


    *---- "Warning" The "Red FTM output" must go to the SWM or it can destroy all receivers!
    *---- "Warning" the PI (power supply) must be inside for it is NOT weather resistant.
    *---- The SWM can be place inside or outside
    *---- The maximum coax length coming off the SWM to each receiver is a max of 100"
    *---- When only (1) SWM port. There must have the terminator cap installed or a 15’ piece of coax
    *---- Use good quality compression connectors





    Advance Troubleshooting Methods


    *NOTE* we will add more symptoms, and match tips worked to the problems later on

    Is the Receiver or the SWM at Fault?

    Symptoms

    When boots it went to searching for signal on step 2 of 2 and just stayed there until it timed out. (All other SWM receivers are working.)
    Advance trouble shooting Tips:
    1. Enter the setup menu and check all signal strengths for each Sat tuner and SWM tuner. If this shows random transponders scattered around Sats 101, 110 and 119 with signal on tuner 1, but doesn’t show any SWM tuners, the SWM should be considered as working at this point.
    2. Perform a menu reset or RBR (red button reset), to verify if any of the same results reoccurs.
    3. If (2) doesn’t resolve the problem, perform a hard power-off. Turn off the unit and pull the power cord for a minimum of 10 minutes. (No results? Proceed to step 4)
    4. Make sure all receivers are unplugged including the SWM. Switch the HR20 line to the SWM-2 port on the SWM. Re-plug the pi for the SWM and wait a few minutes. Then one-by-one power up each receiver allowing boot-up time. (No results? Proceed to step 5)
    5. Perform a “reset everything”. (no results? Proceed to step 6)
    If 1-5 has not provided any favorable results. Time for more drastic measures to be taken in the next following Tips:
    6. Grounding is very touchy issue to find and fix. This is sometimes just easier to re-install a new ground wire to the SWM (Must meet your local electrical code enforcements). Then perform another RBR. (no results? Proceed to step 6)
    7. Existing RG-6 coax (or RG59) could be pinched somewhere between the SWM module and receivers’. If using any splitters, remove all and run all new coax with new quality compression fittings to rule out that possibility of bad cables, compression connectors, and splitters. Then follow the proper procedure in step (4) to fire everything back up. (No results? Proceed to step 8)
    8. Perform another reset everything to redo satellite setup. Now if there is still no favorable results with it being connected on SWM-1 & SWM -2 ports. Switch to the Legacy ports, to see if it works. Leave the H21 or H20-100 on the SWM-1 port. If the HR20 now works on the Legacy port as well as the H21 or H20-100 still works on the SWM. (Please follow the conclusion)


    From all the troubleshooting steps listed above, the HR-20 is more than likely at fault and will need to be replaced. Out of these steps (1-8) the H21 is working on the SWM-1 (2); therefore, the SWM should be considered ok.

    For some time the SWM-5 & the SWM-8 have been out for field trials and now are showing up in normal installs. We all saw and admired the installation photo's that many great CE'ers produced, taking large amounts of time so we all can learn.

    I would like to take this one step further, providing trouble shooting tips for the SWM's. In the post above, I will continue to list the awesome tips that we come up with. I've started with just a few basic ones that i can think of. What kind of more advance trouble shooting can we put together?

    When will the SWM be available to the regular customers of Directv?

    Later this year. Some are reporting that SWM5's were included in install this month! But no further word on sales to existing customers.
    I would say to add that they do not want their BBC's connected to a receiver using SWM1 or SWM2 ports.

    I have forgotten that before.

    OVERVIEW:
    Single Wire Multiswitch (SWM) technology allows you to distribute satellite and Over The Air (OTA) antenna signals on a single cable. Currently the only SWM Receivers are:

    D12 Standard Definition Receiver - Single Tuner
    H20 / H21 HD Receivers - Single Tuner
    HR20 DIRECTV PLUS HD DVR - Dual Tuner

    + Older "Legacy" Receiver Tuners must be connected individually to the Legacy ports.
    + The SWM5 can serve up to 5 SWM tuners plus 2 Legacy tuners. For example, it might serve (2) HR20's, (1) H20's, and (1) TiVo.
    + The SWM8 can serve up to 8 SWM tuners plus 3 Legacy tuners. For example, it might serve (3) HR20's, (2) H20's, (1) TiVo, and 1 older receiver.
    + "SWM" is now used instead of "FTM". Older units may have a label of FTM instead of SWM but they mean the same thing.

    Warning 1: The minimum 15' cable length from Power Supply to SWM.
    Warning 2: The Power Suppliy's Red SWM (FTM) output must go to the SWM or it can destroy all receivers!
    Warning 3: Only an experienced installer should install a SWM. DIRECTV may install at no cost.

    STEPS:
    1. Log satellite transponder and OTA signal strength.
    2. Power down and unplug all Satellite Receivers.
    3. Connect (4) Dish AT-9 (or AU-9) RG6 to SWM satellite inputs (max 40'). Flex 1 & 2 are for other satellite dishes.
    4. SWM8 Optional: connect Antenna to SWM8 OTA input.
    . . SWM5 Optional: connect Antenna to the Combiner Diplexer Ant input.
    5. Connect SWM receiver SWM input to the power inserter white IRD connector, or to line from splitter. (Optional: Connect SWM Receiver's SWM Input to Diplexer Sat Out.)
    6. Optional: Connect Diplexer Ant to the receiver's OTA.
    7. Optional: Connect Diplexer Sat to the receiver's SWM/FTM input.
    8. Optional: Connect Diplexer Combined Input to Power Supply White IRD connector.
    9. Optional: Connect SWM Legacy outputs to up to (3) legacy tuners, 2 for SWM5.
    10. Remove previously used BBC's from receivers and put back in box. DO NOT USE BBC's.
    11. Connect Power Supply white IRD to SWM Receiver SWM1 input (or optionals splitter or diplexer).
    12. Plug in SWM8 Power Supply (optional: into same UPS/surge for HR20.)
    13. Verify green LED through vent slot. Wait 5 minute.
    14. Power up legacy receivers one at a time allowing full boot and verify transponder signal strengths.
    15. Plug in receivers. They should begin rebooting automatically.
    16. Check the satellite signal strengths on each satellite receiver. Check FTM signal strength on SWM receivers.
    17. Check signal strengths on OTA channels (if you are using Over The Air inputs).
    18. As always, make sure all connections are tight, avoid splitters and diplexers if possible, and always follow grounding instructions.

    SWM to dish will work with slightly longer coax, if it's good coax. I'm having to run just over 60' of cable between my SWM and dish. D* has give their "OK" for this and it is working well.

    Change "pi must be put in correctly or it will damage HR-20" to "pi must be wired correctly or it will damage ALL FTM recievers" or something like that... ;)

    Mine are also about 55 to 60 from dish to SWM and I have not had a problem at all.

    I changed the text to read:

    Warning 2: The Red FTM output must go to the SWM or it can destroy all receivers!

    How's that?

    I am at 60' as well without problems. But like you that is very good, new cable with new connectors.

    The SWM materials state Maximum of 40' so I wrote it that way.

    I'm not sure how/where to post that it will work outside of the recommended lengths.
    The 15' minimum for the PI to SWM has worked with only 6'.
    The 40' maximum to the dish works at 60'.
    I know why D* posts it and that "we" should follow it, but shouldn't we also post the variations that have worked also? :confused:

    Shouldn't it be?:

    Warning 2: The Red SWM output on the power inserter (PI) must go to the SWM or it can destroy all receivers!

    Since what they are trying to do is have the red to red be connected.

    Hmm...maybe red isn't a good color. Especially if you get a color blind installer.

    I would add...

    *---- If using splitters and more than one SWM, Check & verify that the splitters pass power on only one leg

    ok, could we also include symptoms that might best match with the "check and verify list"..

    so i'll go first.
    every other transponder is working, and the HR20 was doing a searching for signal.

    from my own experience, i had this happen when the ground wire wasn't connected.

    what else could we match it up on the check & verify list, with different symptoms? i will continue to add these as we progress.

    thanks
    James
