In another recent thread discussing weak S10 power supplies its suggested you can slave one stb to another to boost available line power. Can someone describe the correct method/hookup for doing this? Most stbs have both a LNB line in and a loop port so what gets connected to what in what order and how do you control your video output? Is this a practical solution for a power challenged receiver?
Oblio,
The antenna or the LNBF connects to the IF IN (or LNB IN) input on the MASTER receiver. The LOOP OUT port of the MASTER connects to the IF IN (or LNB IN) input of the SLAVE receiver.
Both receivers should be connected to a TV obviously, so that that you can see what you are controlling on each receiver.
The MASTER receiver provides power for the motor, the LNBF and any external switches you have installed. The MASTER receiver controls the motor positioning, the internal switch of the LNBF to control polarity and any external switches port selections to control either the polarity of some LNBFs or to select between different antennas if you have a dish farm.
Since the MASTER controls either the motor or the external switches to select between various fixed point dishes, it has control over the satellite selection. The MASTER also controls all the LNB switching to select the polarity (vertical / horizontal linear or right / left circular). Because of this, the SLAVE receiver may only look at the channels which are of the same polarity and on the same satellite that the MASTER is tuned to.
You will either have to utilize two TV sets. One so that you can see what the MASTER is set to and one to watch with the SLAVE, or one TV with multiple inputs so that you can switch back and forth between the two receivers.
Is this practical? In certain setups it could be. But, overall I don't think I would want to put up with the drawbacks personally.
