Hi I am looking at putting together a demo system that i can take to my clients. I wont to use two pc's running schedule plus on each. One will display a site map of a building showing lighting circuits, pirs, switches etc. The other will be the main site control system, which will be provided at say the site managers pc. This will enable the site manager to override pir's, set light level controls, building all on and off etc. My question is how can i connect the two pc together so demostrate the c-bus / schedule plus system. Can this be done using just a serial connection or ethernet. Thanks for any help.
