CFA633 USB Family

Robust packet based communications protocol with 16-bit CRC.
Compact size: fits in a 1U rack mount case (35 mm overall height).
Advanced digital GPIO control with PWM output.
Four fan connectors with RPM monitoring or variable PWM fan power control.
Available in a 5.25" half-height LCD drive bay kit, (see mounting bracket photos).
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.
Temperature monitoring: up to 32 channels at up to 0.5 deg C absolute accuracy. Ready-to-use WRDOWY17 Dallas Semiconductor 1-Wire temperature sensors are optional. Alternatively, you can create your own sensors using DS1822 or DS18B20 parts and the tutorial on creating temperature sensors.
Integrated LED backlit 6-button translucent silicon keypad with screened legend.
"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.

For reference only. For design purposes, please use the specifications in the datasheet.

Products Affected:	CFA633-YYB-KS, CFA633-TMC-KS, CFA633-RMC-KS, CFA633-YYB-KU, CFA633-TMC-KU, CFA633-RMC-KU, CFA633-YYH-KS, CFA633-TMI-KS, CFA633-YYH-KU, CFA633-TMI-KU, CFA633-RDI-KU, CFA633-RDI-KS, CFA633-TFH-KU, CFA633-TFH-KS
Date Issued:	February 13, 2012
Summary:	CFA633 Firmware 2v1
Last revision:	v2.0
Description:	As part of our continuous improvement process, Crystalfontz America, Inc. is releasing a new version of firmware for the 2v0 hardware based CFA633 family of intelligent modules.
Reason:	Fixes: Command 10 (0x0A) Read 8 Bytes of LCD Memory. Corrected the range of data[0] to reflect the native addressing of the LCD controller. Command 11 (0x0B) Set LCD Cursor position. Updated algorithm used for updating cursor location. Corrects potential power-up corruption of boot state with the serial interface (-KS). Enhancements: Command 4 (0x04) Store current state as boot state. Firmware compares stored stated and current state. Returns error if there is a difference. Command 28 (0x1C) Set ATX Power switch functionality. Added auto polarity switch. Improved pulse length functionality, and added feature to hold until system off during power down. Updates: Command 1 (0x01) Get Hardware & Firmware Version. Modules with the serial interface, KS, will report: "CFA633:h2.0,s2v1" Modules with the USB interface, KU, will report: "CFA633:h2.0,u2v1"
Impact:	All CFA633 modules are impacted by the new firmware release.
Recommendation:	It is recommended that all customers migrate to this new firmware release.
Availability:	Starting 2012-03-01 all standard modules will ship with this new version of the firmware. Customers with Defined Part (DP) numbers will not have their modules shipped with this new firmware automatically. Please contact our engineering support team at support@crystalfontz.com.
Price Change:	This update to the firmware does not affect the pricing of the CFA633 family of modules.
