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.

Part Change Notice #10402

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.

Products Affected:	CFA633-YYH-KS, CFA633-TMI-KS, CFA633-YYH-KU, CFA633-TMI-KU
Date Issued:	November 23, 2010
Summary:	Firmware Changes
Description:	As announced in a PCN 10286 http://www.crystalfontz.com/products/pcn.phtml?id=10286 on 2010/10/06, the new CFA633 hardware v2.0 / Firmware version 2.0 ("s2.0" for serial modules and "u2.0" for USB modules) is fit, form, and function compatible with previous versions of the CFA633 series (hardware versions 1.5x). Data Sheet. v0.1 was published 2010/11/22 for CFA633 hardware v2.0 / Firmware s2.0/u2.0. The Data Sheet includes descriptions of two command changes: In command 5 (0x05): Reboot CFA633, Reset Host, or Power Off Host, the module now knows if it is coming from a power up or from a reset. This in turn improves the bootup sequence. A note was added to describe the brief delay at bootup when more than one of the optional fans are on. In command 12 (0x0C): Set LCD Cursor Style, cursor style choice "3" changed from "3 = blinking block plus underscore" to "3 = blinking underscore cursor." The rate at which the cursor blinks is faster than in previous CFA633 versions (HW v1.x). For information on additional changes, please see the Data Sheet’s Revision History. For a technical bulletin comparing CFA633 modules by version number, see PCN 10291 at http://www.crystalfontz.com/products/pcn.phtml?id=10291 published 2010/11/10.
