Features:

These external modules are extremely rugged and well-suited for dusty or damp locations. They are splash-resistant and resistant to dust.

Includes 10' black low-drop captive USB "A" cable.

The outline of the case is very compact compared to the size of the display--only slightly larger than the bare module.

These are perfect modules to be used in a wall-mounted or desktop application, since the display can be mounted at eye-level.

With the addition of a simple metal bracket the CFA-634XE can form the bulk of a POS pole mounted display.

USB Interface: The USB interface version of the 634 has the full feature set of the serial interface 634, but allows connection to a USB port--using only a single cable for both power and data. This cable is Full compatibility with existing software is preserved by using our "Virtual COM port" driver. Connect the display, install the driver, and your computer will now show an additional COM port any time the display is connected.

Full 634 v2.0 feature set: This USB version retains the entire feature set of the original 634 v2.0:
  • The LCD material for the positive displays is 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 as 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 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.
  • 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.
