I have a Scope Stuff LX200GPS data cable 5 meters long. It is wired same as the one in my observatory that I bought years ago from Scope Stuff.
When I plug the new one into either of my LX200 a message comes back - cannot detect device error 203. So I figure something else is buggered inside the cable. This cable is round and heavily shielded. I can easily make up a new 5 meter cable from flat 4 core telephone line, BUT does it need to be shielded?
Thanks
