I tried building my own, but whenever I try to export it, an error comes up as "Communications failure." Does anybody have advice?
Is everything turned on? How is your converter wired? What version of software are you using? USB or serial? What is your computer hardware configuration?
Could be a hundred different issues. To troubleshoot we need details and pictures. Comm failure would say to me something isn't on.. the Comm port isn't set correctly or there's a loose wire somewhere.
