INTRODUCTION

COMPARISON TO CFA533

If your project does not need the fan connections, the CFA533 family is an economical replacement for the CFA633

family. In November 2010, we issued a Technical Bulletin that describes the differences between the CFA533 family and

three versions of the CFA633 family. Please see Part Change Notice #10291.

MAIN FEATURES



16 characters x 2 lines LCD with keypad and high-level interface. Will fit nicely in a 1U rack mount case (35 mm

overall height).



Module has a 6 o’clock viewing direction. See Definition of 6 O'clock and 12:00 O'clock Viewing Angles (Pg. 20).



Bidirectional 19200 / 115200 baud ESD-protected RS-232 interface.



Edge-lit red LED backlight with negative FFSTN near-black transmissive mode LCD. Displays red characters on

dark red background. Integrated red LED backlit 6-button translucent silicone keypad. The display can be read in

normal office lighting and in dark areas. Not recommended for use in sunlight; may be washed out.



An optional 5.25-inch half-height drive bay kit with mounting bracket is available. See CFA633 Kit Configurator.



Fully decoded keypad: any key combination is valid and unique.



Robust packet based communications protocol with 16-bit CRC.



Nonvolatile memory capability (EEPROM):



Customize the “power-on” display settings.



16-byte “scratch” register for storing IP address, netmask, system serial number . . .



Firmware support for CFA633-RDI-KS allows:



ATX power supply control functionality allows the buttons on the CFA633-RDI-KS to replace the Power and

Reset switches on your system, simplifying front panel design.



Four fan connectors with RPM monitoring and variable PWM fan power control. Fail-safe fan power settings

allows safe host fan control based on temperature. See 25 (0x19): Set Fan Power Fail-Safe.



Add up to 32 Crystalfontz WR-DOW-Y17 cables with DOW (Dallas One-Wire) DS18B20 temperature sensors.

Monitor temperatures at up to 0.5°C absolute accuracy.



Hardware watchdog can reset host system on host software failure.



“Live Display” shows up to eight temperature or four fan readings without host intervention, allowing fans and

temperatures to be shown immediately at boot, even before the host operating system is loaded.



RoHS compliant.



Factories have ISO certification.



Product materials are in compliance with the regulations related to the EU Directive 2006/121/EC for Registration,

Evaluation, Authorization and Restriction of Chemicals (REACH).
