Abstract
The remote control unit has a selection mechanism for selecting any one of a number of categories of equipment to be controlled. The commands available for keyboard input in any given category are automatically displayed to the user upon selection of the category. Switches are provided for user selection of the model number of any one of a number of manufacturers of the equipment within the category to be controlled. Operation of the switches allows program controlled read-outs of formats stored in memory. An infra-red LED is then energized in accordance with the format to transmit the signal to the unit to be controlled.
