Digital Workshop

I have a project that requires a touch screen opus presentation that when a particular page is shown, an led will light up on a topographical map hanging on a wall. There will be around 500 pages/lights. I guess I will need a relay card within the computer, and have seen 32 channel ones available that I could use in a binary fashion, connected to a binary converter to give me the 500 switches. Does anyone know of any particular relay cards that work with opus? I don’t have any programming knowledge other than simple basic. My guess is that opus could call a small exe file for each page, which would switch the appropriate relays. Or is there another way?

Many Thanks

I think the best solution would be to write a small Windows application that accepts a command line switch with the information about the switches to change.
You can then launch the same program from each Opus button with a different parameter for the relevant set of lights.

Skipper,

I know one user uses a MIDI control board to control a night club's lightshow using Opus. The way I bleive it works is he has Opus launch midi files; the midi controler then get the midi signal and triggers the apropiate relay/triac.

A bit of searching came up with this site which may be of help
