Hi all,
I need to combine several analog signals (DC voltage swing from 0V to 12VDC, from switches, relays, etc.) and send it to another device using multiplexing.
I first need to find more information regarding multiplexing. I am hoping I can find a way to send bi-directional signals through 3 wires (Hi, Low, Shield).
But I have two cameras that need to be implemented into my design (just two CCD cameras that monitor a machine). But the signal from the camera goes back to the unit sending the multiplexed signal!
Right now, I have 16 wires sending signal between both devices.
I need to simplify, ideally, 3 wire multiplex would be best.
(Concert lighting uses "DMX" which has 512 channels of control, interesting stuff indeed. But I don't think I've seen bi-directional DMX in that industry).
I guess the camera signal would have to be converted to digital (it has composite outputs).
Oh, and if anyone has any information where I can find multiplexing information, that would be greatly appreciated (information leading me towards design).
Cheers!
Robert
