[QUOTE="jeallen01, post: 1149289, member: 176704"] Correct for a DiSEqC- controlled motor and that's what I set up here to control the Dark Motors under the Gibby & TD110, and which worked pretty flawlessly. OTOH, obviously [B][I]not for [/I][/B]a "traditional" 36V dish motor which would require: - compatible receivers with appropriate Motor +/-, position sensor, ground output terminals = 4 in most receivers [I]- [/I]would also need 1 or 2 V-Boxes if the receivers don't have those compatible outputs - a switch which provides switch-over for those 4 conductors from each receiver => needs 2x "4-in" and 1x "4-out" and only 2-way. That's not particularly technically challenging as the circuits are all DC/very low frequency, provided one knows where to look [I](industrial component distributors like Farnell, CPC Farnell, RS Components, etc.)[/I] - would also need something like an SPS (as above) to switch the LNB coax input (assuming that a modern "simple" LNB is used). Given the above, then the sequence for changing from 1 receiver to another would probably be: - switch BOTH receivers OFF (to avoid "SPS "confusion"!) - move the 4-way switch from one position to the other - switch ON the receiver you want to use. - Surf away on that receiver! OTOH, one would probably have to then do quite a lot of adjustments to the settings in one of the receivers to ensure it outputs exactly the same azimuth number signals for each satellite as does the other one, or else the two receivers will drive the motor to slightly different longitude positions - two receivers are rarely that accurate (even if of the same model)! I had that problem even with two slightly different versions of the Octagon SX88 connected via an SPS to the DSEqC Dark Motor under the Gibby! [/QUOTE]
