OK but I am still unsure how this can help swapping the logical ID unless you have two drives of the same type (which is where it mostly doesn't matter) or at least with similar capabilities and even then that's not clear to me. And since the signals were expected to be separated on the PC side, if I use one DS line to control Motor, will the appropriate DS still act as such? Or if it's performing dual function, then will the PC cope with that, while expecting both to be separated. Yeah... -- SD! - http://e4aws.silverdr.com/Received on 2019-01-09 19:00:03
