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!
