Part Change Notice #10658: Depreciation of ‘Drive Bay Kit Configurator’ / New part numbers for drive bay kits.

Products Affected: CFA631-RMF-KU, CFA633-YYB-KS, CFA633-TMC-KS, CFA633-RMC-KS, CFA633-YYB-KU, CFA633-TMC-KU, CFA633-RMC-KU, CFA635-YYE-KS, CFA635-TMF-KS, CFA635-TFE-KS, CFA635-TMF-KL, CFA635-TFE-KL, CFA631-TMF-KU, CFA635-TFE-KU, CFA635-YYE-KL, CFA635-TMF-KU, CFA635-YYE-KU, CFA533-YYH-KS, CFA533-YYH-KU, CFA533-TMI-KS, CFA533-TMI-KU, CFA533-YYH-KL, CFA533-TMI-KL, CFA533-YYH-KC, CFA533-TMI-KC, CFA533-TMI-KI, CFA533-YYH-KI, CFA633-YYH-KS, CFA633-TMI-KS, CFA633-YYH-KU, CFA633-TMI-KU, CFA632-YFH-KS, CFA632-YDI-KS, CFA632-YFH-KU, CFA632-YDI-KU, CFA634-TFH-KS, CFA634-TMI-KS, CFA634-YFH-KS, CFA634-YDI-KS, CFA634-TFH-KU, CFA634-TMI-KU, CFA634-YFH-KU, CFA634-YDI-KU, CFA633-RDI-KU, CFA633-RDI-KS, CFA533-TFH-KU, CFA533-TFH-KS, CFA633-TFH-KU, CFA633-TFH-KS, CFA533-TFH-KL, CFA533-TFH-KC, CFA735-TFK-KR, CFA735-TFK-KT, CFA735-TML-KR, CFA735-TML-KT, CFA735-YYK-KR, CFA735-YYK-KT, CFA632-YDI-KL, CFA632-YDI-KN, CFA632-YDI-KC, CFA632-YDI-KP, CFA632-YFH-KL, CFA632-YFH-KN, CFA632-YFH-KC, CFA632-YFH-KP, CFA634-YDI-KC, CFA634-TMI-KC, CFA634-YFH-KC, CFA634-TFH-KC, CFA634-YFH-KL, CFA634-TFH-KL, CFA634-TMI-KL, CFA634-YDI-KL, CFA634-TFH-KP, CFA634-YFH-KP, CFA634-TMI-KP, CFA634-YDI-KP, CFA634-TFH-KN, CFA634-YFH-KN, CFA634-TMI-KN, CFA634-YDI-KN, CFA631P-TMF-KU
Date Issued: July 1, 2015
Summary: Depreciation 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.

Part Change Notice #10428: CFA631 family Firmware version 3v1

Products Affected: CFA631-RMF-KU, CFA631-TMF-KU
Date Issued: August 3, 2012
Summary: CFA631 family Firmware version 3v1
Last revision: v2.1
Description: The CFA631 family of modules is being revised to support a new LCD controller chip, the Rockworks RW1067. The changes to the CFA631 3v1 firmware are as follows.

For hardware changes, please see PCN #10427.

Updates:
Command 1 (0x01): Get Hardware & Firmware Version
Modules with the USB interface, -KU suffix, will report: CFA631:h2v4,u3v1

Command 12 (0x0C): Set LCD Cursor Style
Option 4 = inverting, blinking block is no longer supported. This option will result in a blinking underscore.

Command 22 (0x16): Send Command Directly to the LCD Controller
Any command sent specifically to the Samsung S6A0073 will need to be reviewed / modified for the commands / registers of the Rockworks RW1067. Please contact the Crystalfontz Engineering Support Team at support@crystalfontz.com for the RW1067 datasheet.

Enhancements:
Command 28 (0x1C): Set ATX Power Switch Functionality
Added auto polarity switch.
Improved pulse length functionality.
Added feature to hold until system off during power down.

Fixes:
Updates to timings and sequence of Serial interface power up to prevent possible corruption of data displayed
Reason: The Samsung S6A0073 LCD controller used was scheduled as End of Life. This EOL affected a number of intelligent modules from Crystalfontz America, Inc. The replacement RW1067 LCD controller was developed as a replacement for the Samsung S6A0073 LCD controller for Crystalfontz America, Inc by Rockworks (China).
Impact: This announcement impacts all variants, interfaces, and part numbers that currently use the CFA631 family of modules. The CFA631 can continue to be used in current and future designs.
Recommendation: Continue to order and build with the CFA631 as required by production schedules. Transition to the CFA631 h2v4 hardware and supporting firmware should be a seamless process. Engineering samples for qualification for the revised CFA631 are scheduled to be available Q3 of 2012.

Please contact our logistics team for engineering samples sales@crystalfontz.com.

Availability: Q3 2012
Review / Update customer Defined Part custom firmware

Q3 2012
New hardware and supporting firmware available for engineering samples

Estimated - Begin transition to h2v4 hardware as v2.1 hardware inventory is depleted

NOTE: We will not ship production orders of 3v0 hardware until the v2.1 inventory is depleted

Q4 2012
Estimated - CFA631 v2.1 hardware to be exhausted, transition to CFA631 h2v4 hardware / u3v1 firmware complete.
Price Change: 2012-08-03
No scheduled price change at this time.

Part Change Notice #10427: CFA631 family Hardware version 2v4

Products Affected: CFA631-RMF-KU, CFA631-TMF-KU
Date Issued: August 3, 2012
Summary: CFA631 family Hardware version 2v4
Last revision: v2.1
Description: The CFA631 family of modules is being revised to support a new LCD controller chip, the Rockworks RW1067. The changes to the CFA631 2v4 hardware are as follows:

1. LCD controller changing from Samsung S6A0073 to Rockworks RW1067

2. Supporting driving circuitry between the LCD controller and the LCD glass has been updated to support the Rockworks RW1067

3. The PCB layout has been updated to support the Rockworks RW1067

4. Firmware updates to support the Rockworks RW1067 and functional improvements – PCN #10428

The only changes to the CFA631 family are to support the Rockworks RW1067 controller.
There are no other physical changes to the CFA631.
Reason: The Samsung S6A0073 LCD controller used was scheduled as End of Life. This EOL affected a number of intelligent modules from Crystalfontz America, Inc.
