Features:

  • LED backlit STN 20x4 LCD
  • Integrated LED backlit 6-button translucent silicon keypad with screened legend

    • Yellow-green backlit positive mode LCD, yellow/green keypad backlight ("YYE")
    • White backlit negative mode LCD, blue keypad backlight ("TMF")
  • Fully decoded keypad: any key combination is valid and unique
  • LCD characters are contiguous in both X and Y directions to allow the host software to display "gapless" bar graphs in horizontal or vertical directions
  • USB interface for both power and data (115200 baud equivalent throughput)
  • Robust packet based communications protocol with 16-bit CRC
  • Compact size: fits in a 1U rack mount case (37mm overall height)
  • ATX power supply control functionality allows the buttons on the CFA-635 to replace the "power" and "reset" buttons on your system, simplifying your front panel design
