DMX Stage lighting

[Stephen Barncard]

here's a site with all the MIDI specs:  -- click on HARDWARE for interface.

>>  From the little I know about stage lighting - they use a dc voltage
>>(0-10v) to control dimmers. So to begin, you'd need an A-D controller
>>that can work with REV, such as the one describe earlier last week:
>
>One whole bunch of dimmers I control, in a big house, use 0-10VDC 
>per dimmer which we make in other ways. Another whole bunch of 
>dimmers I control, in a theater, can use DMX-512. That is a looped, 
>multiplexed, time-divided system (each device has an address (0-511) 
>that determines its time slot. For all I know, common DMX-512 
>interfaces may have 0-10VDC outputs.
>
>Like Stephen says, its pretty easy to get at MIDI if you can do 
>serial. Old mac serial ports could do it directly, but I haven't 
>since.
