New in v2.0:

This display is the "v2.0" version of our serial display series. This version is generally command and mechanically compatible with our earlier 1.x series displays, while adding many improvements:

• The LCD material is now FSTN (Film compensated Super Twisted Nematic) instead of STN. FSTN gives better contrast, faster response and makes an all-around more readable display.
• The display now has the ability to store a customized boot screen of your design in its EEPROM. All features of the display are controlled: characters displayed, user-definable characters, backlight setting, contrast setting, cursor position, cursor style, "wrap" setting, "scroll" setting, and even the scrolling marquee.
• The baud rates supported are now 19200, 9600, 4800 and 2400 baud. 1200 baud is no longer supported.
• The PCB silkscreen has an abbreviated jumper setting table, so all the jumper settings are always in easy reference.
• The CGROM is an enhanced version with many more useful characters: numeric superscripts, icons, mathematical symbols, some fractions, a great variety of arrows, many currency symbols, and more.
• The processor’s reset circuit has been improved to handle a wider range of slow-turn-on power supply conditions.

Other Features:

• DB9 connector provided for simple RS-232 hookup
• Large, easy to read characters: 7.3mm (0.287") character height
• Available with bright, even, software adjustable LED backlighting or in a low-power reflective model
• Software controlled contrast
• "Gapless" horizontal bargraphs
• Software controlled terminal style automatic scrolling and line wrapping
• Unique "Scrolling Marquee" feature continuously scrolls a message across the display without host intervention.
• Low speed "SPI" (F_{clk max}=18KHz) and "Inverted TTL" RS-232 for embedded applications
• Buffered communication
• Single board construction--no connectors to fail
• Large display area in a compact 108mm x 43mm (4.25" x 1.69")package
• Thin:
  • Reflective is 15.9mm (0.626") including DB-9 connector
  • LED Backlit is 19.9mm (0.783") including DB-9 connector
• Negative voltage for contrast generated on board
• Extended voltage (9-15v) and 5v power inputs standard on all modules for the controller. Backlight is 5v only.
• Low power: Non-backlight operation will self-power from the DTR and RTS lines of most serial ports.
• Available in a LCD drive bay kit, (see mounting bracket photos)
