Please note that there is a bug in 7.072 firmware. The firmware works but upgrade to a higher firmware by direct connection to USB or via another UCM will not work. It will result in the KT03 having a blank LCD and not being able to start. The only way to upgrade this firmware is by programming cable

However please note that Comfigurator 3.9.9 has a bug that KT03 button cannot activate Responses. Please upgrade to Comfigurator 3.10.3 or later

Known Bugs

1. KT03 Button trigger Responses does not work for Response number > 999. A workaround is to change the button to Increment Counter. The counter will trigger Counter Response
2. Output status in a button for Output > 64 will not work
   

Bugs Fixed

1. removed 2 extra lines in some icons which should not be there (proble from Domopor installer)
   

Improvements

1. Improved firmware upgrade - Allow KT03 to be upgraded successfully when upgrade failed or KT03 reset or switched off and on, unless boot sector is corrupted

New Features

1. KT03 Button Element added new Comfort Action Types; Increment Counter, Decrement Counter, Output On, Output Off, Output Toggle, Flag On, Flag Off, Flag Toggle. This is in addition to Response and Keypad Key. These new action types allows outputs, Counters and Flags to be directly controlled by KT03 without having to use Responses. The use of Responses is problematic because editing Responses may cause the Response number referenced by KT03 to change, which requires Write to KT03 to synchronise Response numbers between KT03 and Comfort. Comfigurator 3.10.3 is required. see http://www.comfortforums.com/forum90/4216.html
2. KT03  event log  fixed bugs which only displayed the 1st page of events. Now all events can be scrolled in KT03

1. When firmware upgrade of KT03 version 7  by RS485 bus fails, a scan u? Will report version 7.000 instead of 6.000 so that the KT03 can still be upgraded by Bus. UCM Firmware 6 cannot be upgraded by Bus

Known Bugs

1. Event Log does not display on KT03
2. Display of Output status above 64 does not work

This firmware upgrade is important due to the last point above. KT03 and UCM firmware version 7can be upgraded by Bus as well as by direct connection (by USB). When the upgrade by Bus fails for any reason , it should be possible to repeat the upgrade by Bus. However, for older KT03 firmware versions the KT03  which failed upgrade wiill report as version 6.000, so Comfigurator will not allow the repeat of firmware upgrade  because only firmware version 7 can be upgraded. The new firmware 7.016 will report its firmware as 7.000 instead of 6.000 so the upgrade can be repeated.

Changes in this version include

1. KT03 will detect if it is not polled or if there is a clash in IDs (Duplicate IDs) and display a message, and also allow the ID to be changed in Settings without needing to enter the user code
2. Calibration accuracy has been improved
3. Implement new ID setting method by Comfigurator
4. ID of FF means ID is unassigned.
   
5. Fixed Rectangular Border Misalignment near the right edge of the screen
6. Settings page Keypad size of buttons has been enlarged to match the default keypad page buttons
7. Improved Firmware upgrade reliability and faster time to erase Flash.
   
8. Firmware Upgrade by UCM through Comfort Bus has been implemented (as well as through KT03 USB Port)
   
9. Write to Comfort by Bus has been implemented (as well as through KT03 USB Port)

Known Issues

1. ID of 8 is invalid. When reset the ID will revert to FF (Unassigned)
2. When Trouble alarm is restored, the OFF LED will turn off instead of steady ON
3. When Alert or Alarm state occurs, the AC LED flashes instead of the ARM LED

1. Allow Firmware Upgrade By Bus (require UCM version 7 and Comfort Version 7 with Comfigurator 3.6.x). This allows KT03 to be upgraded from the LAN or Internet without having to go on site. This is a major benefit for installers when the customer site is far away. However note that Bus upgrade is much slower than direct USB upgrade
   
2. Also allows Upgrade of other KT03s and UCMs through the USB port
3. Allows Write and Read to EEPROM by Comfigurator via UCM (as well by by the KT03 USB port). This allows remote programming of KT03. However the write and read by UCM willl be much slower, about 30 minutes instead of 5 minutes by the KT03 USB port.
   
4. KT03 Firmware numbering now follows the UCM, hence firmware is now version 7
   
5. Allow ID to change by Comfigurator 3.6.x
6. Greatly Improved Firmware Upgrade by Bus and Direct

KT03 firmware is upgraded via the KT03 USB port, or via another UCM. Upgrading by the KT03s USB port is much faster than by another UCM, but the 2nd method is possible via the Internet

To upgrade K03 firmware via its USB port, Connect the PC to the KT03 USB port and run Comfigurator. Comfigurator 3.8.x or later should be used for this procedure.

Go to Options > Settings, Select USB and select the handle to the right.
If you have another UCM/USB connected then you will see 2 USB serial numbers. Disconnect the USB from the UCM so that you can identify the correct KT03 USB port

Check the \"Via KT03\" box




In Comfigurator, go to the Modules Tab, right click the KT03 on the left pane.




Select Check for Firmware Updates. This automatically downloads the latest firmware from the Cytech server and starts the firmware upgrade.

You will be asked to enable Engineer Mode before the firmware upgrade can start. Press F and 0 on any keypad to enable Engineer mode.

The firmware upgrade takes a few minutes  via the KT03\'s USB port
If the firmware upgrade fails for any reason do not reset the KT03. Repeat the firmware upgrade.
If the upgrade fails and cannot recover even after repeated attempts,  you must use the UCM with Programming cable to upgrade the KT03 Firmware

The procedure for upgrading via another UCM is shown in the next post

4. Improved Upgrade firmware by direct connection
5. Fixed Bug in Portrait Orientation display

Effective 1 August 2012


Note that firmware on systems that are purchased from distributors may not have the latest version due to the supply chain. Firmware for KT03 can be upgraded using a UCM by Direct Connection to PC, see http://www.comfortforums.com/forum4/2283.html
