  Date Issued:	July 1, 2015
  Summary:	Deprecation of "Drive Bay Kit Configurator" / New part numbers for drive bay kits.
  Description:	Starting August 1, 2015 the "Drive Bay Kit Configurator" located at https://www.crystalfontz.com/products/select_kit.html will no longer be functional for ordering one of our Serial or USB displays (CFA533, CFA631, CFA632, CFA633, CFA634, CFA635, and CFA735) in a bracket or SLED. This functionality is being moved to the Customize and Add to Cart process when checking out. This will allow for further customization by our customers to better fit their needs. This change will eliminate the current "kits", but will add options not previously available such as pre-configured ATX functionality, and ALL the currently available interfaces will be orderable in a drive bay bracket or SLED. The new part numbers will have the bracket / SLED and overlay type as a PREFIX to the configured part number. The choice for bracket / SLED to a display order will be via the cart options. Our CFA835 displays were introduced with these configuration options. To see how the new options will look, and what the new part numbers will look like, please see one of our CFA835 parts: https://www.crystalfontz.com/cart/addtocart.php?product_id=2277&qty=1 NOTE: The SLED is only available for the CFA635, CFA735, and CFA835 products.
  Reason:	As part of our continuous improvement process, we are integrating the ordering of displays in drive bay and SLED kits as part of the display ordering process.
  Impact:	Drive bay kits in their current configuration will no longer be available.
  Recommendation:	Place orders prior to 2015-08-01 for upcoming production needs via our website or by contacting our logistics department via email: sales@crystalfontz.com, or by calling 1-888-206-9720 (International call +1-509-892-1200). After the 2015-08-01, please contact our engineering department via support@crystalfontz.com to assist you with ordering your bracket / SLED kits.
  Availability:	Starting 2015-08-01, the bracket and SLED options for our serial and USB display will be part of the ordering process for the displays
  Price Change:	Pricing bracket / SLED configurations will reflect manufacturing costs.

  Product Update #10429: Hardware version update from 0vA to 1v0.

  Products Affected:	CFA735-TFK-KR, CFA735-TFK-KT, CFA735-TML-KR, CFA735-TML-KT, CFA735-YYK-KR, CFA735-YYK-KT
  Date Issued:	August 23, 2012
  Summary:	Hardware version update from 0vA to 1v0.
  Last revision:	0vA
  Description:	Manufacturer was changed for the micro-USB connector and microSD card socket.
  Reason:	As generally occurs in the process between Pilot and Production Release, product/process improvements were identified and implemented. These improvements in manufacturability are reflected in the product between hardware versions 0vA and 1v0. They do not represent a form, fit or function change.
  Impact:	String returned by command 1 (get HW and FW version) will reflect the new hardware version 1v0: "CFA735:h1v0,f0vB" will now be the response when queried using command 1.
  Recommendation:	If the end-user application relies on the firmware string response being the same as previous versions, it will need to be changed to accept the new response to command 1.
  Availability:	As product becomes available, estimated completion by Q2 2013.
  Price Change:	N/A

  Description:	As part of our continuous improvement process, a new version of the CFA735 firmware is being released to address functional and performance issues. There is a supporting hardware revision for this firmware release. See PCN 10400.
  Reason:	Correct Command 0x9 Data[0] to only accept 0-7 as the index for the custom characters. In 0v9 0-15 were valid but 8-15 were references to 0-7 respectively. Fix H1 Pins not functioning when used as GPIOs Fix extraneous byte received by the host when using the serial interface after a module reset. For this fix to be fully effective the module requires a 1 MΩ 0603 resistor at RC2 (which is standard in the 0vA hardware).
  Impact:	All CFA735 family modules are affected with this firmware update. Firmware version 0vA requires supporting hardware version 0vA.
  Recommendation:	All CFA735 modules that use the serial interface or GPIO lines should update to the new 0vA firmware and supporting hardware. If you require assistance loading the 0603 1MΩ resistor in RC2, please contact support@crystalfontz.com.
