Scenario: I have JZ10's already programmed that I would like to pull the OS and projects from to install on a new JZ20. I purchased the programming kit and am experimenting with it, but am having trouble just communicating. I get to the point when U90 Ladder is synchronizing Com Ports and then I get an error saying communications could not be established. Any help, or point me at a tutorial, would be greatly appreciated. I've read through everything I can find in the help section but am still stuck. Thanks!
