Upgrading from UCM/Cbus1

It is possible to Upgrade to UCM/CBUS2 from the UCM/Cbus1 under the following conditions;
  1. The SIM Module is the ST7 version as shown in the above post. The older non-ST7 photo is shown below. if the SIM Module is the older type, a CBUS01 submodule can be purchased from Cytech or distributors.
  2. The U2 socket requires an  EEPROM for Cbus parameters. UCM/CBUS1 does NOT have an EEPROM as it is not required for UCM/CBUS1. A Microchip 24LC256 EEPROM can be purchased and inserted into the socket (with power off). If there is no U2 socket, then it is not uogradable and a new UCM/CBUS2 is required - DO NOT try to solder an IC socket or EEPROM into PCB, as this requires special soldering tools. Any attempt will probably damage the PCB as the IC holes are filled with solder
  3. If the UCM/Cbus has non-flashable firmware ie CBUS firmware < 5.100 then it is not upgradable. A new UCM/Cbus2 is required

The below photo shows the old non-ST7 SIM Module which is not suitable for UCM/CBUS2. A new CBUS01 module must be purchased

In the photo, the U2 socket is not present on the UCM Baseboard. This cannot be upgraded to UCM/CBUS2, and a new UCM/CBUS2 must be purchased.





To Upgrade a UCM/CBUS to UCM/CBUS2, you need to use Comfigurator 3.8.6 (beta).
Upgrade your UCM/CBUS to the latest firmware (7.045 or above)

See http://www.comfortforums.com/forum92/3400.html for instructions on how to upgrade firmware in general

This is a 2 step process. First upgrade to the latest cbus1 firmware  and then upgrade to UCM/CBUS2 firmware

In the Modules Tab, right click on the UCM/Cbus and select "Check for Firmware Upgrades"





This upgrades to the latest UCM/Cbus firmware  which is allowed to be upgraded to UCM/CBUS2


Download the UCM/Cbus2 firmware  from http://www.cytech.biz/ucmcbus2_firmware.html
Unzip the zip file into a .cbf file

Right Click on the UCM/CBUS as shown above, and select "Upgrade Firmware from Local File" Browse to the folder where the cbf file is saved and select the cbf file.
The UCM/CBUS1 firmware will be upgraded to UCM/CBUS2.



Note that older ucm/cbus firmware < 7.041 cannot be upgraded directly to UCM/Cbus2 without upgrading to the latest UCM/Cbus1 firmware first.

You should see the UCM/Cbus2 firmware 7.042 as shown




If the UCM is still shown as UCM/CBUS and not UCM/CBUS2, reset Comfort and scan again. Comfort may use the last scanned value of the UCM

Click on the Cbus UCM on the left pane. You should see the Cbus configurator screen as shown below. This means you have successfully upgraded to UCM/Cbus2

If the UCM/Cbus PCB does not have the U2 EEPROM or the CBUS SIM Module is not the ST7 version, the ERR (D4) Red LED on the UCM/CBus PCB will flash continuously and the Status line in the UCM/Cbus2 Comfigurator will show
"EEPROM missing/faulty" or
"CBUS module is lower than V5. Replace CBUS submodule"


IMPORTANT
The C-Bus actions in the cclx file are automatically converted to a new format for UCM/CBUS2, as the formats of the commands in Comfort are not compatible. WRITE to COMFORT now so that the new action formats are updated to Comfort. Save the upgraded cclx  file under a new name so that the old cclx file can be retrieved if you wish to downgrade back to UCM/CBUS1




Built-in Cbus Applications
Clocks/Timekeeping, Security and Zones boxes are shown.
Check to enable the built-in Application and uncheck to disable it.

Clocks and Timekeeping: if enabled, Comfort acts as a Time Master on C-Bus. Comfort time is synchronised to Cbus according to Cbus Time Master rules. Comfort is a secondary Time master on C-Bus. If disabled, Comfort Time is not set to C-Bus and vice versa.

Security: If checked, this enables the C-Bus security application. Security messages are sent and received between Comfort and C-Bus. This requires a C-Bus device which implements the Security Application eg C-Touch mark 2 or C-Gate. If UCM/Cbus does not receive an acknowledgement from Cbus when sending Security Messages, it will automatically disable the Security application so as to avoid retransmits on C-Bus. However if C-Bus sends a Security message to Comfort, this automatically enables the Security Application.

see http://www.comfortforums.com/view_topic.php?id=2262&forum_id=11&jump_to=9184#p9184 for information about C-Touch to Comfort

Zones: This sends zone information on C-Bus Custom Application 01 (which was implemented in UCM/CBUS1). This is not necessary as C-Touch Mark 2 shows zone information on the Sealed and Unsealed function. Do not Enable this application as it will cause unneccesary messages on Cbus. It may be removed in the future.


UCM/CBUS Properties
This shows the properties of the CBUS SIM, Click on "Read Properties" on the CBus menu bar to read the properties from UCM/CBUS. These are READ-ONLY properties, for information only

Unit Adddress: This is the Unit Address on C-Bus. It can be changed by the C-Bus toolkit
CBus SIM Version: This shows the SIM firmware version. ST7 should be 5.04.00 or above. If the SIM version is less than 5, the Status bar will show "SIM Version is less than v5" and the ERROR LED will flash continuously
Network Voltage: This is the voltage on C-Bus.
SIM Options: These are the options set on C-Bus Interface. These are for information only.
