dp301 with superdish software to dish 500

[truckracer]

my neighbor's superdish got stolen from his front yard the other day. He called dish and they are going to send someone out to replace it at his cost.
however we were wondering if for the time being if we could install his old dish 500 dual lnb dish with its integrated sw-21.

Since the dp-301 is running software for use with dishpro accessories like the sw-44 or 64 (can't remember what he's got) will the software control the sw-21 like it was before he ordered the locals and his receiver's software got updated. I know that the dish 500 relies on voltage switching 13-18v for polarity changes and dishpro technology does not do this.

thanks for your help-trucker

i am not one hundered percent positive, but i am pretty sure it will work. you just won't get 105 or 121.

Yes it will work but you will not get your local channels. Just make sure you do a check switch so that it will recognize the Dish500 setup with the built in switch. When you get the replacement SuperDish make sure that the check switch is done again so that it recognizes the SuperDish hardware along with the DP-34 switch again. If the Dish500 is not DishPro then you may want to do a check switch with the dish disconnected before hooking it up so that it does not burn out your legacy lnbf's and/or switch (twin) then do another check switch after you get the signal in.

Also if you have a legacy sw-44 or sw-64 switch then you could use your legacy Dish500 in conjunction with a PrimeStar dish and PrimeStar lnbf but the dish may be very hard to tune in. If it is a DishPro Dish500 then it would not work. I assume that you have a legacy Dish500 since you mentioned a sw-44 and sw-64. The PrimeStar dish and PrimeStar lnbf would be used for your locals at 105 or 121 and would save you all that expense of what a SuperDish would cost.

Another option (depending on the location of the SuperDish) is that he could use a hookup to your SuperDish out of the DP-34 port that you have if there are any leftover. All you have to do is run RG-6 wire rated at 2.2 GHZ (2200 MHZ) or higher from the DP-34 switch to the receivers.

run a check switch BEFORE you hook up the old stuff. Going from DishPro to Legacy is a little different

Run check switch with nothing hooked up to clear it
Then hook up dish and run check switch

What he and Iceberg said. Do it!

Hey Stargazer I have been installing for Dish and Direct for a few years, I have done dish since 99, I still have a legacy twin 500 at the shop even though I install a lot of DishPro Twins and Superdishes. I have hooked up IRD's for a long time at shop that someone has brought into test that was set for DishPro, to check out the Receiver. Also like a said, there is a dish 500 with a legacy twin set-up at the shop. I have not burnt it out yet after all the tests.

So how do you burn it out, I have also done these tests with sw-44, sw-21, and sw-64 with no probs. Just wondering maybe I am missing something about the way these things work.

Thanks

I seem to recall there was also the issue of a different mast size. As I recall it the superdish uses a slightly larger diameter mast than the Dish 500 so it may not fit on the existing pole.

 

[truckracer]

they took the pole too!

I am assuming they hacksawed or used one of those cordless reciprocating saws. There is only 6 inches or so of pole left out of the ground. what nerve

If you have a DishPro setup and your switch matrix indicates DishProand try to check legacy hardware then you could cause too much voltage to run through the legacy hardware. DishPro works differently than legacy in that it runs on a higher voltage than legacy.

This does not mean that you will burn it out but if you do it multiple times to the same hardware your chances of burning it out increases. I found out about it here on the forums a while back and make sure I clear out the switch matrix if I have DishPro showing in it. If you had a legacy setup and connected DishPro hardware to it then it shouldnt burn it out although it may not work correctly until you perform another check switch. When you have DishPro switches detected in your switch matrix it operates as if DishPro switches and lnbf's are hooked up to it. It cannot automatically detect a switchover to a legacy receiver which may be looking for a lower voltage for the receiver, switch, and lnbf's.

One way of preventing this is to have a legacy dish and a DishPro dish.

Legacy used/uses 13/18V, DishPro also uses 13/18V.
But ok.

Yes I understand that DishPro is Different, but I see no difference in voltage

Go to Post #8 and you will see someone else suggesting to clear out the switch matrix at the following link I will give you: http://www.dbstalk.com/showthread.php?postid=62023

Sorry, wrong. DishPro uses ONLY 18+VDC (at the receiver).

There are several reasons for this. Probably the main one is to allow for longer cable runs before the unavoidable voltage drop prevents proper operation.

 

[Stargazer]

DishPro changes the frequency instead of the voltage in order to know the difference between the odd and even transponders (polarities) right? If so that would be the reason why a higher rated cabling such as 2.2 GHZ (2200 MHZ) rated cabling would be required.

dish 500 dual lnb dish with its integrated sw-21.

You're describing a Twin, not dual. The legacy version has an integrated SW42.

Well, I guess it can be put that way.

Legacy (unstacked) uses 950-1450MHz - one 500MHz transponder band.
DishPro (stacked) adds 1650-2150MHz (1550-2050MHz) for another band.

DishPro basic puts the odd TP set for a given bird on the low band, and the even ones on high.

DishProPlus adds brains so that ANY TP set can be on either band.

Ok, unplugging the Sat in ports and running a check switch does nothing but waste time! This is a myth. All E* receivers are designed to clear the matrix everytime the checkswitch test button is selected.

You are wrong. They will start from their last known setup.

 

[Stargazer]

They start from their last known setup otherwise if everytime the power would go out or you would lose the satellite signal it would clear out the matrix and you would have to do a checkswitch each time.

I just did this today, we had a bad 311, we failed to hook the 3:4 switch to the proper line. It started doing 50 tests. We found the proper line, put it on port 1 of the 3:4 and re-ran the check switch, did not power off or unplug anythin to "clear the matrix". It procceded to to 3 tests. Superdish 105.
