Can you hook up two dishes with two different motors behind a 2x1 diseqc switch? Will the receiver switch before it gives the motor command??
Are you planning on two receivers and two motors? And you want both receivers to be able to access both KU dishes? If so, your equipment list needs change.
Motor #1 would be hooked-up to Horizontal input for dish #1 and looped out to LNBF #1, port #1. Motor #2 would be hooked-up to Horizontal input for dish #2 and looped out to LNBF #2, port #1. The Multi-switch Vertical input for dish #1 would be connected to LNBF #1, port #2. The Multi-switch Vertical input for dish #2 would be connected to LNBF #2, port #2,
LNBF polarity is controlled by voltage. 18Vdc = Horizontal / 13Vdc = Vertical
Don't know where there is a diagram of this, as it is not normally done.
Place the motor on the leg that carries the most voltage. The motor will move faster with the higher voltage.
BTW... DiSEqC/22KHZ control signals travel further and are higher amplitude when transported on the higher voltage!
Correct, a channel (or in the menus, a transponder) selects the voltage automatically outputted by the receiver in the default mode.
On a multi-switch connected to a dual output LNBF, one port label H-18v is fixed to horizontal polarity (18Vdc) by the switch and the other port labeled V-13v is fixed to vertical (13Vdc). The switch provides constant fixed voltage to each LNB port. The switch then selects between dish #1(22KHz tone_OFF) Vertical or Horizontal and dish #2 (22KHz-ON) Vertical or Horizontal.
Now instead of feeding you a salmon dinner, I will teach you to fish.
Google some of the terms we have discussed:
MultiSwitch, External Power, 22KHz, 4x2 (or also 5x2), Satellite, LNBF
This switch should be top of list:
5x2 S-4120-GX
Eagle Aspen Multi Switch
Probably a good switch candidate. Maybe someone might comment if it passes 22KHz/DiSEqC signals through the satellite ports at all times. I'm thinking that it does, but can't speak from experience.
The Multi-switch Vertical input for dish #1 would be connected to LNBF #1, port #2. The Multi-switch Vertical input for dish #2 would be connected to LNBF #2, port #2,
These are dual (2) output LNBFs. 1 port locked to vertical the other port locked to horizontal.
To support two receivers with with simultaneous horizontal and vertical polarities the a LNBF must be dual output or bandstacked type.
