Robust packet based communications protocol with 16-bit CRC
Compact size: fits in a 1U rack mount case (35mm overall height)
ATX power supply control functionality allows the buttons on the CFA-633 to replace the "power" and "reset" buttons on your system, simplifying your front panel design
Built-in re-programmable microcontroller
Four fan connectors with RPM monitoring or variable PWM fan power control
"Fail-Safe" fan power setting allows safe host fan control based on temperature
Non-volatile memory ("EEPROM") capability: Customize the "power-on" display settings plus a 16-byte "scratch" register for storing IP, netmask, system serial number, etc.
RS-232 to Dallas Semiconductor 1-Wire bridge functionality allows control of other 1-Wire compatible devices (ADC, voltage monitoring, current monitoring, RTC, GPIO, counters, identification/encryption, additional hardware required)
