The video signal that carries the microscope images is fed into this PC via a video overlay card, hence both the control interface and the microscope image are integrated onto a single SVGA computer monitor.
Remote control is performed via a second PC system that also contains a video overlay card.
The microscope computer is controlled by this second PC system with the aid of PC Anywhere, an application that allows control of a remote PC either via a serial line, modem or as in this case a local area network. The video signal is set in real time from the microscope to the remote computer over the University Capus Cable TV Network. The remote control PC may be located in any of the networked lecture rooms on campus and connected to a video projection system that allows the demonstration of the microscope operation and capabilities to a large audience.
