  • LED backlit STN 20x4 LCD
  • Integrated LED backlit 6-button translucent silicon keypad with screened legend
  • Four bi-color (red + green) LEDs. The LEDs’ brightness can controlled by the host software, which allows mixing the LEDs to produce other colors (yellow and orange)
  • Three color options:
    • Yellow-green backlit positive mode LCD, yellow/green keypad backlight ("YYE")
    • White backlit negative mode LCD, blue keypad backlight ("TMF")
    • White backlit positive mode LCD, white keypad backlight ("TFE")
  • 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
  • Serial (RS232 or 0-5v) interface (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 (requires additional cables or hardware).
  • Built-in factory re-programmable microcontroller
  • Non-volatile memory capability ("EEPROM"):
    • Customize the "power-on" display and LED settings
    • 16-byte "scratch" register for storing IP, netmask, system serial number . . .
  • Customizable firmware and configurable hardware can be modified at the factory to add specific features for your system needs. Minimum order and tooling fee may apply for custom firmware:
    • Analog I/O
    • Provide "dongle" functionality for system copy protection
    • Autonomous hardware monitoring
    • Customize the "power-on" settings
