UCM/Ethernet Fails to Connect
#21
Hi, requested photos emailed for you to review. let me know if you require anything further.
#22
The cables seem to be correct
I think there is a problem with the 4 way headers, so the 4 way cable between UCM and Comfort are not working

Instead of using the programming cable or the 4 way cable, connect wires from the Comfort 12V/COM KA/KB terminal blocks to the UCM 12V/COM KA/KB terminal block
This should give a better connection

Hi, Thanks for that. Do I just use Cat5 cable between these or do I need something else. Also is the a diagram of how tis is done as I don\'t want to mess anything else up.
#24
Use CAT 5 cable
There is no special diagram needed
just KA to KA KB to KB, 12V to 12V, COM to COM
Use  pairs for KA/KB and for 12V/GND

Hi, installed the cables as advised and everything up and running. I have to say you have been a great help and your advice was much appreciated. Thank you so much.

What is the firmware version of the UCM/GSM that you are trying to upgrade with the file GSM 6.005 and how are you doing that, with the programming cable or the method of Upgrading by Comfort Bus?

Upgrading by Comfort Bus is only possible if the module is already version 6
If the module is version 5, then you have to use the programming cable

I am going to close this topic called \"UCM/Ethernet Fails to Connect\" so that it does not become too long and filled with different issues and be difficult for others to follow

Please start a new topic
