Hi I'm new to C-Bus and am in the early stages of setting up a network. I have the latest version of tool kit running on windows vista, a PCI (RS232) + 12 channel relay. When scanning to find the network tool kit recognises that the port is in use but will not open the network and cannot retrieve any data from it. I am starting from scratch and have tried the RS232 port and RJ45. I'm stuck:-( If anyone knows what the problem might be any suggestions would be much appreciated. Many Thanks Tom
