In the early 1800's Sir William Hershel discovered Infrared. He found that on moving a thermometer across the spectrum of colors, the heat would increase towards red. As he continued to move and when the thermometer passed the red, the heating continued to rise. This area is what we call the “Infrared” or “Below Red”.
Today the Infrared port is also commonly referred to as the Infrared Data Association (IRDA). This is a port much alike the one we would find on a TV/VCR remote. We need to configure only the Infrared ports on both source and destination and there is no need to physically connect the ports using wires.
Infrared port provides high-speed digital exchange through the typical PC UART/Serial port at 9600-115200 bits/s, and in some cases it is compatible to high-speed extensions of up to 1Mb/s and 4Mb/s.
