I got a SEM just the other day and for some reason only two of the landing lights go on when the switch is in gear down by default. So I was going to add a line to put it on. The light is number 19, added in line 13 in the screenshot:
Once finished, I click "set" I get the error: "Write data fault, No new data!!!", and in the top right it says write fault also. My added line then vanishes. Am I doing something wrong? I get the same error when trying to set up a virtual controller (need it split to 2 to keep it under 32 buttons), except despite the error the change sticks in that case (two devices exist after clicking set).
