Hello, There is no schematic in your post. I guess you refer to this part of the manual schematic 1kf02 As you see there even the not connected inputs need to be grounded. It's done to avoid interference , but you are right in some occacions this can cause problems. The recommendation is for most cases, sometimes in case off trouble you can try to forget the grounding. Follow the manual to avoid problems, if there are problems when everything connected by the book, try some thing like ground lifting at the CPU or module. Most of the time problems arise if third party components are used. If in doubt, ask product support. Regards, Marcjan |
