Logic Level Serial / RS232 / USB

The CFA835 product series are intelligent graphic LCD modules that offer USB and Serial interface, 6 button keypad, 4 status LED's and 5 GPIO.

Versatile and reliable packet based communications with set of 61 commands simplifies programming for your particular application.
Commands include tools to draw lines, rectangles, and circles. For example, create a chart to display temperature fluctuations over time.
Five GPIOs can be used to control other devices or can be configured for optional ATX functionality.
Only a single supply is needed. Wide power supply voltage range (V_DD= +3.3v to +5.0v) is perfect for embedded systems.
Made for the demands of a commercial environment, temperature operating range is 20°C minimum to +70°C maximum.
The 12:00 o'clock viewing angle ensures optimal viewing for your products viewed at or below eye level.
Fully decoded 6-button keypad allows key combinations. Large translucent silicone keys are responsive.
Edge-lit backlight with 12 LEDs, 6 per side.
Adjustable backlight and contrast. Backlight and contrast are fully voltage regulated over the power supply range.
Front of display has four bicolor (red + green) LED status lights. For example, green could indicate "acceptable speed" while yellow-orange indicates "heavy usage, slow".
Add multiple optional CFA-FBSCABs to customize your order for temperature sensing and fan controls (up to 256 temperature sensors and 64 fans).
Easily integrate the CFA835 into your design with choice to two types of optional mounting brackets.
Attractive stainless steel bezel or select from 4 overlay colors when used with a bracket.

Products Affected:	CFA835-TML, CFA835-TFK, CFA835-YYK
Date Issued:	July 29, 2015
Summary:	CFA635, CFA735, and CFA835 displays with ATX (power on / off / reset) functionality enabled serial cable bundle change.
Description:	As part of our continuous improvement process, CFA635 KS, CFA735 KT, and CFA835 display modules with the ATX (power on / off / reset) functionality enabled will have their RS-232 SERIAL cable bundle options changed from a serial cable and WRPWRY24 to a serial cable and a WRPWRY25. With TX (power on / off / reset) functionality enabled, additional
Reason:	The WRPWRY24 is a power only cable and suitable for powering the CFA635, CFA735, and CFA835 when properly configured. When the displays are configured for ATX (power on / off / reset) functionality additional connections are necessary for proper operation. The WRPWRY25 offers the additional connections.
Impact:	Full functionality will now be available as the part is shipped.
Availability:	Immediate.
Price Change:	There is no price change associated with this change.
