The display can be controlled remotely by a Connection of data computer through the serial data bus. A typical signals example of this, is the MediCal software that controls the display. MediCal runs on a PC that is connected through the serial data bus. This PC is not necessarily the same computer as the one that produces the video signals. Unlike the video signals, it is possible to daisy- chain the serial data bus. This means you can control different displays from one PC. To connect the data

Important considerations The best environment for diagnostic imaging is one with controlled and dimmed ambient light. The human eye's sensitivity depends on the ambient light strength. It is most sensitive to small contrast changes (or subtle image details) at limited ambient light levels. The best ambient light level, expressed in Lux, depends on the application. An office illumination typically requires 500 Lux. A dimmed environment, like a softcopy room, requires less than 100 Lux. Usin
