PC used to control 2000 anolog outports

I'm hoping for information regrading my current project. To control 1000 pistons using 2000 anolog outputs. The system doesn't require feedback and each piston has to be controlled in 10ms

Thanks in advance

First of all the on/off time of the transistor output will need to be around 1-2 mSec. Push one way turn off and push the other way in < 10mSec. Also with maybe 1000 rungs of ladder to control I think the scan rate would be 10mSec / 1000. Thats quick!

Try using rtlinux (www.rtlinux.org). It will give you the timing resolution that you need. Due to the timing limitations of the PC bus, however, it might be necessary to set up several computers, and coordinate them via a pulse in the parallel port.

I hope that this helps.
