Hello, everyone.
I have a task of assembling receiving headend in quite a remote location with limited access for most of the year. That is - it should not be serviceable. There are 4 directions (13E, 36E, 42E, 46E), which I will connect with fiber LNB/IRS (Triax, or Global Invacom, whichever will be available at the moment), 17x32 multiswitch and whole bunch of receivers.
Making everything in N+1 or double quantities is the best way out, but not always possible. Antennae (and, therefore, LNBs) are out of question - there is simply no place for 8 antennae there, I'm struggling to fit 4 of a descent size (1.8 m with heating in lower part). Then I'm putting 1x2 optical splitter to connect 2x4 fiber IRS, whom I then connect to two 17x32 Polytron Mutiswitches
So far so good. Now that's where it all goes haywire. There are 32 inputs on 16 receiver cards, and I need to connect each input to both multiswitches. 1x2 DISEqC is out of question - receivers must control multiswitches with 14/18V+0/22Khz+DISEqC 2.0 and multiswitches have committed DISEqC, so they won't ignore commands, sent ot switches before them.
What I am looking for is technically something like manual switch, but controlled electronically, like relay, so that I could send a signal from Arduino's GPIO and switch it back and forth.
Is there any sane way of doing it other than using solenoids to move the damn switch? I really don't want anything mechanically moving inside my headend.
