It can also take input from the ViewStation by an SVGA cable or RCA plugs; if you hook it up before you turn the ViewStation on, the ViewStation will use it as a second monitor and try to do intelligent things with it. To set it up as an external monitor, plug the SVGA cable (recommended--the black cable with yellow ends) into the extra SVGA port on the back of the ViewStation; the bottom row is output, the top is input. If you hook up by an SVGA or RCA cable, you need to set the "Mode" to "Video".
To use "zoom" or "focus", press the appropriate button, and then use the arrow buttons to zoom or focus in or out.
