Mmm this could also be, we discussed about the ASCOM driver and its possible cause for this error,... for me this was strange I changed to lodestar and we updated the driver,... but after thinking about it we could not see a relation between the driver and the ST4 port,...
Important is that pushing the buttons at the same time unlocks the ST4 again,... I was messuring and so on and did not find any issue,... I was confused.
However did you try to step back to the 1.5.2 driver to test it? It is maybe easier than working on the cables....
Here is the link:

Normaly ST4 and the driver are not interacting with each other so it is confusing,...
@Armando this is what I wanted to say, I think it could be something TDM or Mgen is producing however,... Isi also feels the problem since he did the update,... I am not sure anymore if it is at the end related to the driver somehow,... the interesting thing is that Isi sees a relation with GoTo commands,... I cannot do GoTo commands with CDC so I am not sure if this has an relevance in this case,... I still get errors on CDC when I do GoTo,...
@Isi do you do the GoTos by handpad??
When we where testing the ST4 issue we made it happen once that ST4 worked after downgrade to 1.5.2 but only short,... then the same error again but we didnt do a GoTo we simply upgraded to the new driver and had TDM running...
