Many people think of T-Switches only as a way to route data from a single output source, such as a computer, to one of several peripheral devices, such as printers. T-Switches
perform that function, of course, but are not limited to that role. The T-Switch is a completely "passive" device, and will work no matter which direction information is being
sent in. Either side of the T-Switch can be the "input" or "output" side.
