Using SW21 and SW21X

[amoda1]

Just like to use the configuration listed on this web site.

http://www.dishnetwork.com/downloads/pdf/technology/installation/install-4.pdf

I understand that the legacy twin has a built in Switch. Can I use one SW-21 and one SW-21X (which I currently have) instead of two SW-21’s as shown.

The Twin has the equivilant to an SW21x inside the unit so an SW21x may be a problem though I am not sure. The SW21 will work fine.

See ya

The SW21x is identified by Dish receivers as one half of an SW42. The built-in switch on the legacy twin is recognized as a "TWIN." It bascally boils down as to whether the software identity of the sw21x is address the same as the built in switch on the twin. If it is not the same, it will cascade.

The only way to find out is to try it.

What is the difference between an sw21 and an sw21x?

I asssumed they were the same?

No, you MUST use all SW21's if you are using them with a twin.
As others said, a twin is equivalent to an SW21x & an SW42, so you cannot use these 3 switches at the same time.

An SW-21x is not made by DISH and uses compatible technology but not the same as the DISH SW-21.

The SW-21 command set is NOT the same as the SW-21X command set. THAT is why they can be cascaded.

However, the Twin, SW-21X, and SW-42 command sets overlap, so they can NOT be cascaded in any combination.

You're right,the sw21x is for cascade use with a sw21,is for getting 3 point signals(61.5,110,119)and no because is not made by Dish(Microyal)is a very reliable
switch.
