How do you hook up a dish 500 satellite to a captiveworks satellite fta receiver?

[Jeff]

I bought a house with a dish 500 already on my roof but not hooked up. I bought a

captiveworks receiver from craigs list thats already set up i think. The question is the

dish itself has 3 connectors on it, 1 labled lnb and the other two labled 1 and 2. There

are two cables that come from the dish but they are not plugged in. Do i hook up one or

both cables and do i hook it to the nlb plug or the 1 or 2 plug. if i did hook up to nlb do

i hook directly to receiver or do i need a swich or modulator or something. Plus i jusst

hoping its allready pointed in the right direction. INfo on how to hookup would be awesome

THANKS Jeff
