What is needed to connect a stand alone box?

After the H24 is connected to a SWM system then you have to rerun sat setup then select multiswitch first before selecting the dish type to get it to work with the 18" dish again.  DTV receivers auto detect a SWM system and select the correct dish.

The two SWM LNBs you tried the 1 horn is a 3 LNB and the other is a 5 LNB that is no longer need as the 119 sat is not used for US programs.

So on the power inverter, do I connect it to the dish, and to the STB and run the HDMI cable from the STB to the TV or do I run the Inverter to the Dish and coax from the inverter to the TV and then the HDMI cable to the STB?  I feel like such an (Edited per community guidelines).  I can take a motor apart and put it back together and get almost anything to run, but I can't get this TV set up.  It's frustrating.  I'm going back up on Sunday and will try it again.  Let me know which way to connect the power inverter and I'll try it again.  Thanks.

Here is a diagram with a SWM LNB and regular HD receiver:

Cool.  I'll try it on Sunday or Monday depending on what time I get up there.  Is the number in the corner your number?  I have no internet where I am going and my wife's phone internet is slow.  Thanks for the picture.  I work better with pictures.

No, those are the numbers for directv. Since I am a customer like you on a public forum I won’t be posting a phone number.

   You mentioned your problem a page back. You're confused about where the coax goes and why. it does triple duty between the power inserter and the LNB/SWM, on that segment it carries satellite TV channels, an intercom for picking which satellite and channels it puts on the wire, and DC power. Between the Power Inserter and the Receiver it only does double duty carrying the satellite TV channels and the intercom for picking which ones. The Receiver takes care of turning satellite TV channels into pictures. The HDMI cable is strictly for carrying the pictures to a TV set.  

  BTW not everyone here knew everything they were sure about. The H/HR20,21,22 receivers are all SWM capable. They were right that the 21's are obsolete and you should install the 24 or was it a 25? The 21 takes around 20 minutes to self-test and start up. The 24 will be around 7 minutes. all of the 20 series receivers are unloved and don't support some of the newer features, but you don't seem to be interested in those features.

   YES YOU HAVE TO POINT THE DISH AT A SATELLITE TO GET STARTED! Both the azimuth heading and elevation have to get close before the receiver is any help at all for peaking the signal. You'll also need to get the tilt correct before you're done. Print out some pictures of the several adjustment bolts to have with you. 

Thanks, everyone for the responses.  I will attempt this again when I get back up to the cabin, which will be on Sunday.  Hopefully, when I return, I can get back to you with a success story.  Thanks again.

So I went up again this weekend to the cabin.  I tried the HD dish and tried to set it up.  No luck.  I connected the old dish and could see the channels, but there was no picture or sound.  I got a code 722.  I was able to contact the owner and told him there was a number on the screen to call and say "722" when prompted.  He called with me on the phone and Voila, success.  The rest of the week was rainy so I didn't want to push my luck.  I'll try the HD dish the next time I go or he goes.  He only has 1 H24-100 receiver.  Does DTV still issue these boxes?  He would like to get another for the TV on the second floor.  Can he just call DTV and ask or is there some protocol?  Thanks to everyone for their help.  

H24 is expected out of stock. They may still offer H25, which is SWM-only.

If ordered through DirecTV, it must be tech installed and at the residence shown on the account. Otherwise, going through a 3rd party such as Solid Signal to pay the one-time lease cost of $99 would be the option. Either way, it does come with a 24 month service agreement and adds $7 to the monthly bill for the additional TV.

@FOWL1 

Can you elaborate on why you had no luck? We outlined the process explicitly and I was hoping you’d have found it easy to follow through with. If you can suggest a point where you struggle with as far as setting up the dish we may be able to assist.

I think everyone has ignored the possibility that the LNB assembly is a pre-SWM LNB that's used differently If it has only 1 coax cable its an SWM type. If it has has 2 coax cables its an LNB that works with an external SWM or with 2 cables to the receiver, if its 3 or more it was made for use with an external SWM only.

When you try the round dish it connects directly to the receiver. When you try the HD dish it connects to the power injector box and the power injector connects to the receiver. Use the SAT 1 connector on the receiver to connect the power injector, and nothing on the SAT2 connector. (The power injector built into the receiver is only enough for the old round dish, it isn't strong enough for the SWM LNB combo so it rolls over and plays dead. If someone told you you didn't need one, they were wrong.)

Try an old fashioned voltmeter at the dish end of the cables and make sure it really has power. A lot of little RF do-dads intentionally open circuit or short circuit the DC connection, so double check the voltage can get there at no-load. Then check all the coaxial connectors. if any connectors look rusty or crusty or green, they won't pass enough power through. The SWM/LNB has a cable connector buried in the mounting. If you're not checking at the SWM/LNB in front of the reflector (dish) the problem might be that connector is loose or rusty. If you're doing this far from stores buy enough to replace everything and return what you didn't use on Monday.

Now when you try it if all you get is Error 775 then the receiver thinks its talking to the SWM and but its not getting any answers or any satellite signals. The choices are bad power injector, bad coax cable, or bad LNB/SWM assembly. If you know there's power at the LNB/SWN that only leaves the cable from the injector to the receiver and the LNB/SWM module. If you can get the DC voltage there on clean connectors I'm not liking the SWM/LNB assembly. If you could get a type F Tee (not a splitter, just 3 connectors joined in a box) you could be certain there was DC voltage when it was connected and the power injector wasn't a weakling. If you have one of the little "Kill-A-Watt" gizmos you can watch the AC power consumed by the injector when you connect and disconnect the SWM/LNB cable, if it uses 5-10W more connected its probably good.

If you are getting some other error, when you start the receiver push the orange select button as the 1st two screens appear and it will say entering diagnostics, when it gets there find your way to testing the SWM first since you already got everything else to work.

My bad.  I was trying to set up the dish and it wasn't working.  The code 722 said that the STB had been disconnected for a period of time and was therefore not longer registered.  After calling DTV and stating Code "722", the person on the other end flipped a switch and we had TV.  I tried the SWM and HD dish but could not zero in to the location.  I think that was due to the unregistered STB.  I knew where the setting where on the old dish and I kept trying that.  When I got the code 722, it said to push the reset button.  I did, a few times.  I finally called my buddy and told him what the code was and the phone number on the screen.  He called on a different phone while I was on the original line and I have to say, it was the fastest thing I have ever scene.  He gave his account numbers and password etc... and when prompted said Code 722 and bam it was on.  It was rainy and overcast the few days after that, so I didn't want to try to "dial" in the HD Dish with the SWM if fear of losing the TV.  When I go up next, with or without him, I will try to set up the SWM and HD dish.  I don't think I'll have a problem now that the STB is working properly.  I should have mentioned this in the last post, but I was just happy to get the thing working.  I'm sure the HD will go fine now that I can use the STB to help dial it in.  I should have been more clear.  

All CSRs can do is resend the authorizations which your friend can also do by logging into their account. 

Yeah, we're old school and don't really think about the on line stuff, but he called and they registered the STB.  I didn't even realize he could have gone on line until after the call was made.  We got it working on the old dish.  I'm sure we can get the HD dish "dialed" in when we go back up.  Thanks to everyone and I'll let you know what happens.
