  • Page 4: General Information

    Super Bi–refringent Effect (SBE) liquid crystal cell used in this display. For applications where the display is remotely located up to 50 feet from the host processor, the serial data input option should be used. The serial option model is described in IEE specification S03805–06–0200. Description The Daystar Nova module is a self–contained 1/16 multiplexed unit.
  • Page 5: Logical Structure And Function

    LOGICAL STRUCTURE AND FUNCTION Module Block Diagram Figure 1 illustrates the major components of the Daystar Nova module. The microprocessor controls all multiplexing and character decoding. The temperature compensation network optimizes both viewing and contrast ratio for the display over all operating temperatures. LCD Display LCD Row Drivers and LCD Column Drivers...

  • Page 10: Power Up Instructions Sequence

    Power Up Instructions Sequence Upon power up, the Daystar Nova module is set to a default mode of operation. Under some power up circumstances, the default mode may be improperly set. Consequently, the following instructions should always be executed in the host systems initialization routine. Step Operation Function Set for 8 bits...

  • Page 19: Installation Note

    INSTALLATION NOTE To protect the front polarizer from accidental damage it is highly recommended that the LCD be mounted behind a clear glass or polycarbonate window material. It is also recommended that an air gap of at least .030" to .050" minimum be provided between the window material and the surface of the LCD to prevent the transfer of static charges to the front surface of the LCD.
