DN switch/lnbf type

[Gugi47]

There are lot of misinfo floating arround, so I take some time to do a summary of DN lnbf/switch.

LNBF
1. Legacy:
a. single: called single legacy, one output.
b. dual: called dual legacy, 2 outputs.
c. twin: big fat lnbf, 2 outputs, has 2 SW21 switch built-in.
d. quad: big fat lnbf, 4 outputs, has 4 SW 21 switch built-in.
2: DishPro
a. single: called single DishPro, one ouput.
b. dual: called dual DishPro, 2 outputs.
c. twin: big fat lnbf, 2 outputs, has 2 independent Diseqc switch built-in
d. quad: big fat lnbf, 4 outputs, has 4 independent Diseqc switch built-in

Switch
1. Diseqc: 2 versions: 1.0 and 2.0. People having problem with 2.0 version
a. 2 ways: 2 inputs, one output. Switch up to 2 lnbfs.
b. 4 ways: 4 inputs, one output. Switch up to 4 lnbfs.
2. 22khz switch: 2 inputs, one output. Switch up to 2 lnbfs.
3. 0/12v switch: 2 inputs, one output. Switch up to 2 lnbfs. (Note: 0/12v switch needs to be installed close to the receiver, therefore 2 cables has be run into your house)
4. There is no such thing as Diseqc 1.2 or 1.3 switch. The 1.2 and 1.3 (aka USALS) are for motorizing Diseqc h-h mount.
5. DP34. 3 inputs, 4 outputs. Can be used to combine a 2nd (61W or 148W)dish with DP twin or quad, so receiver will get signal from 3 sats.

Switch does not work well
1. SW21
2. Diseqc 2.0 version (either 2 ways or 4 ways).

Dish 500
1. with 2 separate legacy single or dual lnbfs.
2. with legacy twin or quads lnbf, no good.
3. with DishPro twin or quads lnbf, good. Need to use modified transponder list.

Setup:
1. Dish 500 with legacy single/dual lnbfs: use with any working switch stated above to switch between lnbfs. 2nd or 3rd dish can be added using Diseqc 4 ways.
2. Dish 500 with legacy twin/quads lnbf: replace the lnbf with single/dual lnbfs or DishPro twin/quads.
3. Dish 500 with DishPro twin/quads lnbf: good, controlled by Diseqc command using modified transponder list. 2nd dish can be added using DP34 switch.

Hope this post covers some of the misunderstanding about the dish, lnbf, switch types.
