ABSTRACT:
An automatic transfer switch with microprocessor and a display which includes clusters or combinations of display cells. There may, for example, be sixteen display cells for a 16-word display. The display cells are driven by two serially connected shift registers, the input of the first of which is interconnected with the microprocessor. Sixteen digital words are supplied in sequence to the shift registers. One portion of the digital word is then provided in parallel to each of the display cells simultaneously but another portion of the word is supplied to an encoding device which tells which of the sixteen display cells will display that word. One 16 word message requires sixteen reiterations performed at high speed so that it appears that all sixteen display devices are actuated simultaneously to display one multi-word message.
