Kind of confused here. A DMX board that you connected to your system failed to control anything?
If your current system indeed uses a Microplex control protocol, then you need a console that outputs Microplex. There are many lower end consoles that have a 3pin XLR output, but the vast majority output DMX. Leprecon makes plenty of consoles that output microplex and are reliable, so I would look into one of those. Alternatively you could buy a DMX board, and a microplex to DMX converter from Doug Fleenor.We would need a 3 pin output.
IIRC, although still in business, today's http://www.etasys.com/ wants nothing to do with their sullied past of stage lighting control, and does not support those thirty year-old products. Time to replace the dimmer packs. Perhaps something from the SmartBar line.... you can contact ETA in Ohio to see if they can repair your board ...
Correction: DMX to Ultraplex. Protocol converter s are always specified as <what the console speaks> to <what the dimmers listen>.
I was wandering if the standard for ETA Ultra-plex and the standard for NSI Micro-plex are interchangeable. We want to get an NSI board to run ETA dimmers. Was wandering if this is possible. Thanks ahead of time.
They are not interchangeable as they have different timmings [timings].
