CFA835-TML Features

  •    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 (VDD= +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.

Part Change Notice #10669: CFA635, CFA735, and CFA835 displays with ATX (power on / off / reset) functionality enabled serial cable bundle change.

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.
