Westinghouse 84" Whiteboard Control Module

Can you please tell me if I need this or what this is for? I know it’s optional, but I can’t find anything online regarding it. Is it basically a computer? If so, from my understanding the board already has windows 7 or so built in?

Actually, the whiteboard doesn’t have it’s own operating system. It can be connected to an existing system, or you can get this one and attach it directly to the whiteboard and never have to think about it again.
