Abstract

A technique is described whereby infrared transmission of information, used in local area networks (LAN), is controlled so as to enable peripheral devices associated with computers, such as printers, file servers, keyboards, repeaters, modems, joysticks, etc., to share the same ether during the infrared transmission of data to and from the device. A controller provides the controls needed to enable high-speed or low- speed transmission through infrared light-emitting diodes (LEDs), when there is a high-speed packet transmitting requirement or when there is a low-speed packet transmitting requirement. The controller is unique in that temperature considerations of the LEDs are considered in the transmission of data to and from the various devices.
