replacing SW21 with DP34 - problems

[Mathilda]

I've got a SW21 working but want to put in a DP34 to run another receiver. Have a Dish 500 with dual LNBF. When I connect up the DP34 and run the check switch, it sees the 119 and 110 satellites, but says the polarity is odd and won't lock in on either. Change it back to the SW21 and it works fine. Any suggestions?
Thanks,
Mathilda

You probably have a Legacy LNB, which is not compatible with the Dish Pro 34 switch. You need to get Dish Pro LNBs (You can check the DishStore) to work properly with that switch

sw 21 is legacy equipment and won't work with dishpro equipment as the dp 34 is dishpro

Ah, thanks much for the info. Lookin like I have an upgrade in my near future!

I did this upgrade complete with DishPro LNBs and it worked like a charm. I didn't even have to realign my dishes.
