I did rethink and decided, why miss all the fun
. About time I bought a crimper tool, as well.
So I made up a cable, 1->2, 2->1, 3 not connected and 4->4, powered them both up, connected up and tried a download/clone "all". It went away and thought about it for about 15 min - lots of progressing dots on the uploading screen - then said it was done. Both still worked, but the new one wasn't an exact clone - eg. telescope model was not changed to the upload model?
OK, whatever. I had fun making the cable and learning how to use my new crimper tool, and didn't seem to do any damage.
