Hi guys,
I am going to pull it apart this weekend and do some more exploring. Hope to

I think I will make up some extender cables so I can operate the CBT

Hi
Welcome to the reason a lot of us don't have running Cs standards.
There is a very basic wear out mechanism with Cs. Once it's moved from one end

Hello Corby,
Thanks for the help. Yes, could you copy me on the information for the U1

Best regards,
