Hi Guys, In my recent quest for details on devices which can communicate with cbus etc I have found a touchscreen and alarm panel (from different suppliers) who say their product can communicate with CBUS via the PCI. So this would mean I would have a PCI for the alarm, PCI for the touch screen and a PCI for programming. Is this right? Can there be any problems using this approach ? Any suggestions or advise would be appreciated. Regards
