Hi all, New to C-Bus and new to this forum and excited to be apart of it all. I have recently done the Clipsal training Pathway A which includes basic + touchscreen. So I thought Id try a little C-Bus project of my own in a newly built cinema room at my place, and what a better first project than one that integrates Crestron, using the Training kit I purchased which includes a PC interface with a type B Usb port on the front of it. I have another two tv areas which both use Crestron, a single room controller (QM-RMC) in each. I have purchased the same controller for this cinema room, the plan is to get the guys in who did the other rooms to come and program this cinema rooms Crestron while incorporating my C-Bus system, nothing fancy just some scenes and blind control. Anyway to the question. Which is do I need to swap my PC interface which has the Type B usb port on the front to the RS232 interface to allow it all to communicate, Or can i just use a DB9 serial to USB type B adapter? Thanks and I am sorry if this isn't posted in the correct area. Lachlan
