Hi Amanda, I kinda do this sort of stuff for a living and I have yet to find anything that could be classed as a "plug and play" system. The main companies I deal with for of the shelf hardware are ICP ( http://www.icp-australia.com.au ) and Advantech ( http://www.advantech.net.au ) for the basic systems and add on boards. I then tailor software supplied to suit the specific application. And yes I've had to rewrite device drivers to suit. On top of this the application software has almost always been either modifying and gluing open source together and or writing the applications when needed. There is always something out there that at least can form the basis of what you're trying to do. A couple of questions to start. Is it to be in industrial grade machine, (environment is hot, dirty or has to handle vibration )? How many DAC, ADC, Digital IO points are needed? How are these points to be connected to the machine? The USB to Serial: is this USB to rs232 serial or is it connecting two USB ports together? Anyway send me the full specs and I'll give you a better idea of what to look for where. -- Mark Phillips <[EMAIL PROTECTED]> http://www.automatedtestsystems.com.au -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
