Switchboard is best setup using a single computer as a Display Generation System and a second computer (or more) as Schedule Creation. Schedule data is sent to the Display Computer via LAN or Internet connection to an FTP server setup on the Display Computer. (A free Open Source FTP server is included on the Switchboard Installation CD-ROM in the "FTP Support" folder)
Switchboard will operate using a single computer system but you must take the Display System offline while creating new Schedules or capturing Video. An audio source connected to the Line-In of your audio card will have its volume automatically adjusted by Switchboard when switching between the Message Board Display and Video Playback.
