USB + Full Swing RS-232 20x4 character LCD module with Keypad, White Edge LED Backlight, FSTN Positive, Transflective, -20°C to +70°C, 12:00 viewing angle.
LED backlit 20x4 LCD
Integrated LED backlit 6-button translucent silicon keypad with screened legend
Four bicolor (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:
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 and USB interfaces (115200 baud equivalent throughput)
Includes CFARS-232 daughter board for Full-Swing serial communications.
Robust packet based communications protocol with 16-bit CRC
Compact size: fits in a 1U rack mount case (37.5mm overall height)
ATX power supply control functionality allows the buttons on the CFA735 to replace the "power" and "reset" buttons on your system, simplifying your front panel design (requires additional cables or hardware).
Built-in microcontroller with field-upgradeable firmware
Non-volatile memory capability ("EEPROM"):
KT supports full swing RS-232 with CFARS-232 daughter board and USB simultaneously
KR supports 0-5v logic level serial and USB simultaneously
Run STM32 embedded applications on the CFA735 hardware.
Open source firmware for CFA735 displays allows you to customize and write/run your own user code.
- Customize the "power-on" display and LED settings
- 16-byte "scratch" register for storing IP, netmask, system serial number
