635 Series Features:

* 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)
* Two color options:
o Yellow-green backlit positive mode LCD, yellow/green keypad backlight ("YYE")
o 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
* Built-in factory re-programmable microcontroller
* 5.25" half-height drive-bay mounting bracket available (optional)
* Non-volatile memory capability ("EEPROM"):
o Customize the "power-on" display and LED settings
o 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:
o Analog I/O
o Provide "dongle" functionality for system copy protection
o Autonomous hardware monitoring
o Customize the "power-on" settings
* 5.25" half-height drive-bay mounting bracket available (optional)
* Printable 1:1 Acrobat template: 635 one_to_one.pdf
* Mechanical Characteristics::
o 142.0(W) mm x 37.0(H) mm PCB Outline
o 82.95(W) mm x 27.5(H) mm Viewing Area
o 77.95(W) mm x 22.35(H )mm Active Area
o 3.85(W) mm x 5.55(H) mm Character Size
o Thickness:

SCAB Features

* Allows the CFA-631 and CFA-635 to perform the same fan and temperature cooling functions that are available on the CFA-633
o Four fan connectors with RPM monitoring and variable PWM fan power control
o Temperature Monitoring: up to 32 channels at up to 0.5 deg C absolute accuracy
* The CFA-633's four GPIO lines are duplicated on the SCAB, which allow
o ATX power supply control functionality allows the buttons on the CFA-631 or CFA-635 to replace the "power" and "reset" buttons on your system
o Hardware watchdog can reset host on host software failure
o Advanced digital GPIO control with PWM output
* Full control of the cooling features using 631_WinTest for the CFA-631 and 635_WinTest for the CFA-635
* Printable 1:1 Acrobat template: SCAB_one_to_one.pdf
* "UBERSCAB" includes 4 temperature cables (WRDOW17), 4 fan extension cables (WRFANX01), one 3.5" CFA-631/635 to SCAB connector cable (WREXTY19), and one 16" CFA-631/635 to SCAB connector cable (WREXTY15).

Update

Added from information from Crystalfontz

"Safe" Fan Control: If CC2 stops updating the fan speeds, the CFA-635 slams them to 100%, making sure the system is safe. The cable between the SCAB and the CFA-635 has the same sort of safety. If it is disconnected, the fans all go to full on.
