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)
Three color options:
- Yellow-green backlit positive mode LCD, yellow/green keypad backlight ("YYE")
- White backlit negative mode LCD, blue keypad backlight ("TMF")
- White backlit positive mode LCD, white keypad backlight ("TFE")
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
Serial interface (115200 baud equivalent throughput)
- KS and KS1 supports full swing RS-232 with CFARS-232 daughter board
- KL supports 0 -5v logic level serial
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 (requires additional cables or hardware).
Built-in factory re-programmable microcontroller
Non-volatile memory capability ("EEPROM"):
- Customize the "power-on" display and LED settings
- 16-byte "scratch" register for storing IP, netmask, system serial number
Available with USB interface

Date Issued:	June 6, 2010
Summary:	Keypad height change
Description:	Over the next 6 months or so, we will be transitioning to a keypad that is 1.5mm taller than the keypad currently shipping on these modules.
Reason:	We have found that in all cases that we are aware of, the keypad being 1.5mm taller will alleviate some customer difficulties.
Recommendation:	If you need the keypad to remain the same height for your application, please email support@crystalfontz.com so that we can set aside some of the shorter keypads for your company's application.
Availability:	~0-6 months.
Price Change:	None.
