Product Update #10880: CFA635 series firmware revision 2.3

Products Affected: CFA635-TFK-KL, CFA635-TFK-KS, CFA635-TFK-KU, CFA635-TML-KL, CFA635-TML-KS, CFA635-TML-KU, CFA635-YYK-KL, CFA635-YYK-KS, CFA635-YYK-KU, XES635BK-TML-KU, XES635BK-TFK-KU, XES635BK-YYK-KU
Date Issued: September 20, 2017
Summary: CFA635 series firmware revision 2.3
Last revision: 2.1
Description: The CFA635 series of advanced display modules have changed from the previous firmware revision of 2.1 to the new firmware revision 2.3
Reason: This version corrects several issues related to different operating systems and bugs in the command set.
Impact: Command 0 (0x00) – Ping
This command now functions as stated in the datasheet

Command 1 (0x01) – Get Hardware and Firmware Version
This command will report the following strings:
Serial Versions (KS/KL) – CFA635: h1.5,s2.3
USB Versions (KU) – CFA635: h1.5 u2.3

Command 2 (0x02 Write User Flash Area
This command now functions as stated in the datasheet

Command 3 (0x03) Read User Flash Area
This command now functions as stated in the datasheet

Command 10 (0x0A) Read 8 Bytes of LCD Memory
The cursor position is not changed by this command. In version 2.1, the cursor position could be changed by this command, which is incorrect.

Command 12 (0x0C) Set LCD Cursor Style
The Cursor style will have 5 states
0 = No cursor
1 = Blinking block (no underscore)
2 = Static underscore
3 = Blinking block with static underscore
4 = Blinking underscore (no block)

Command 16 (0x10) Set up Fan Reporting
This command now functions as stated in the datasheet

Command 19 (0x13) Set up Temperature Reporting
This command now functions as stated in the datasheet

Command 33 (0x21) Set Baud Rate
This command will have no effect on USB modules. It will return an ACK for compatibility with old versions of host software. For serial modules this command will return an ACK for a 0 (19200 BAUD) or 1 (115200 BAUD). All other entries will return an error as stated in the datasheet

Command 28 (0x1C) Set ATX Power Switch Functionality
The default delay for power pulses was 255(infinite) in 2.1. We have restored the previous default of 32 (1 second) in 2.3

A bug that slowed the response time to certain commands was corrected.

USB power down behavior corrected. The hardware v1.5 USB system behavior was changed to more closely match the hardware v1.2 behavior.

Recommendation: A field upgrade kit containing Version 2.3 firmware and instructions may be downloaded from the individual product page on our website.

Field upgrades must be done using a Windows PC over the USB interface. You will need a USB cable (WR-USB-Y03 or similar) during the upgrade.

We recommend testing the new version CFA635 firmware in your system to verify compatibility.

Product Update #10870: CFA635 series Hardware revision 1.5

Products Affected: CFA635-TFK-KL, CFA635-TFK-KS, CFA635-TFK-KU, CFA635-TML-KL, CFA635-TML-KS, CFA635-TML-KU, CFA635-YYK-KL, CFA635-YYK-KS, CFA635-YYK-KU, XES635BK-TML-KU, XES635BK-TFK-KU, XES635BK-YYK-KU
Date Issued: August 14, 2017
Summary: CFA635 series Hardware revision 1.5
Last revision: 1.2
Description: The CFA635 series of advanced display modules have been changed from the previous hardware revision 1.2 to the new hardware revision 1.5.
Reason: As part of our continuous improvement, the processor and PCB layout have been changed to improve availability, manufacturability and quality.
Impact: The revised CFA635 series has Wide Temperature (-20°C to +70°C) operating range. Part numbers have changed accordingly:
TMF series modules have been renamed TML series.
TFE series modules have been renamed TFK series.
YYE series modules have been renamed YYK series.

The revised CFA635 series now supports a single FBSCAB instead of a SCAB:
All four fans may be used on serial (-KS) and logic level (-KL) modules.
The maximum number of temperature sensors supported is 16.
The ATX power supply control functions previously supported by J8 on the SCAB are now supported by H1 on the CFA-635.

The power supply and backlight circuits have been improved:
The backlight driver is a constant current design—the backlight current and brightness are now insensitive to supply voltage variations.

The backlight design has been improved – you may notice that the backlights appear brighter.

The incoming power supply range is 2.5v to 5.5v, so the CFA635 can easily be used in 3.3v systems.

The yellow backlight of the CFA635-YYK series has been redesigned to improve brightness.

The USB VID/PID have changed. The new values are: 0x223B/0x000B . This change impacts the USB host computer drivers:

USB Drivers for Windows XP, Vista, 7, 8, and 8.1 have changed. The correct driver is Crystalfontz CDC ACM
USB Driver for Windows 10 and later has changed. The correct driver is Crystalfontz USB Serial
USB Driver for Linux has changed. The correct driver is Kernel USB CDC ACM Driver
USB Device filename for Linux has changed. The correct device filename is /dev/ttyACMxx

If your Windows or Linux host OS is up to date, it should automatically select the correct driver.

The mechanical dimensions are unchanged.

Some commands are slightly different. Please refer to the Firmware v2.1 PUN for more information.

Recommendation: Design changes have been made to maximize backward compatibility.

If your application uses ATX power supply control, fan control, or temperature measurement through the SCAB, you will need to change to the equivalent FBSCAB components and cables.

We recommend testing the new version CFA635 in your system to verify compatibility.

Product Update #10869: CFA635 series firmware revision 2.1

Products Affected: CFA635-TFK-KL, CFA635-TFK-KS, CFA635-TFK-KU, CFA635-TML-KL, CFA635-TML-KS, CFA635-TML-KU, CFA635-YYK-KL, CFA635-YYK-KS, CFA635-YYK-KU, XES635BK-TML-KU, XES635BK-TFK-KU, XES635BK-YYK-KU
Date Issued: August 14, 2017
Summary: CFA635 series firmware revision 2.1
Last revision: 2.0
Description: The CFA635 series of advanced display modules have changed from the previous firmware revision of 2.0 to the new firmware revision 2.1.
Reason: As part of our continuous improvement, the firmware has been updated for use with revised hardware v1.5
Impact: Part numbers have changed accordingly:
TMF series modules have been renamed TML series.
TFE series modules have been renamed TFK series.
YYE series modules have been renamed YYK series.

The USB VID/PID have changed. The new values are:
0x223B/0x000B

This change impacts the USB host computer drivers:

USB Drivers for Windows XP, Vista, 7, 8, and 8.1 have changed. The correct driver is Crystalfontz CDC ACM

USB Driver for Windows 10 and later has changed. The correct driver is Crystalfontz USB Serial

USB Driver for Linux has changed. The correct driver is Kernel USB CDC ACM Driver

USB Device filename for Linux has changed. The correct device filename is /dev/ttyACMxx

If your Windows or Linux host OS is up to date, it should automatically select the correct driver.

The new firmware is designed with a priority of backwards compatibility. The following commands will differ from earlier versions:

Command 1 (0x01) – Get Hardware and Firmware Version
This command will report the following strings:
Serial Versions (KS) – CFA635: h1.5,s2.1
USB Versions (KU) – CFA635: h1.5 u2v1

Command 3 (0x03) Read User Flash Area
This command is not working in firmware v2.1. This error will be corrected in the next release.

Command 18 (0x12) Read DOW Device Information
Command 19 (0x13) Set up Temperature Reporting (FBSCAB Required)
Command 20 (0x14) Arbitrary DOW Transaction (FBSCAB Required)
Since the DOW devices are now connected to the FBSCAB, thee maximum number of DOW devices that can be read is the FBSCAB's limit of 16 devices.
Recommendation: Design changes have been made to maximize backward compatibility. For most applications, the CFA635 firmware revision v2.1 will be a form and fit replacement.

If your application uses ATX power supply control, fan control, or temperature measurement through the SCAB, you will need to change to the equivalent FBSCAB components and cables.

We recommend testing the new version CFA635 in your system to verify compatibility.
