Hi,
I have recently upgraded my comfort system to V7 across the board 
Comrfort system 5.164 -> 7.078UCM/ETH3 7.072UCM cbus 5.154 (left the same)UCM universal 6.026 -> 7.065
The system seems fine, however the universal UCM is not playing ball. I mainly use it to send some messages to a server on a specific tcp port. I can see using wireshark that the connection is established, and when i execute a command or trigger a response that executes one, I get data sent over this connection. The problem is that instead of a text message, it just contains one byte (FF). I have tried to update the config numerous times as well as re-write the eeprom. Any pointers would be appreciated.
ThanksPaul

Can you send the cclx file to support@cytech.biz?
was it working with universal 6.026?

We have  looked at the cclx fileThe problem is that the universal baud rate is set at 76800 as shown below
This is used for communications to rs232 interface to external devices which require a certain baud rate. The baud rate applies to the UCM to submodule and to the external device via RS232

However this is meaningless for ethernet because a baud rate is not applicable for TCP/IP
TCP/IPdoes not have a baud rate.The UCM would send data to the ETh03 submodule at 76800 baud according to these settings, but the ETH03 accepts data only at 9600 baud. Please change the baud rate to 9600

This should be better spelled out on the documents

The Universal UCM Manual stated that the baud rate for Ethernet should be set to 76800 and the same baud rate should be set in DS Manager, but this refers to ETH02 where the ethernet baud rate can be changed. This is not so for ETH03 which has a fixed 9600 baud rate

The manual has now been updated http://www.cytech.biz/product_details.php?item_id=354
