in the zip file is a pdf file.the info on the legacy twin/quad is incorrect.
c&P:
A Legacy Twin has an integrated SW42 switch, it is logical to assume that the Legacy Quad has an integrated SW44 switch BUT SW44 switches respond to SW42 commands so the same settings can be used
dish pro plus 1000.2 lnb (3 lnb eyes combined in one housing.)
notice unlike a regular dish pro plus.this one is a triple eyed lnb not just a twin.
if this is your lnb, please state that your using the dish pro plus 1000.2 lnb (3 eyes combined in one housing.)even refer to this pic below to verify is a good idea.
no external switches are required if you only want the 3 sat locations 119/110/129 with up to 3 receivers.
if you want more sat locations or receivers,that's when you will use external switches.
while im thinking about it.this particular lnb could feed 3 dual tuner sonicview 360 Elites using dpp separators.that's 6 tuners! lol.
