With gentle nudging from Mick I have been experimenting with SimVim. I have been having a terrible time getting things to work with MobiFlight, X-Plane, and XPUIPC. Mick suggested I try SimVim. I had looked at it earlier and decided it was to “kludgy” for me. Well I took another look at it and did some direct connect configuration on the work bench. I am happy to report I now have several switches including battery master and ground power on working as they should. The GPU switch was impossible for me with MobiFlight and XPUIPC. I also have fuel pumps,APU start, APU bleed air, MCP ca Course encoder and 7 seg display working plus a couple of annunciators. I wired up a test panel with some switches so I can go from cold/dark to the APU running and providing power to the aircraft with GPU disconnected without using the mouse. Mick, thank you thank you for making the suggestion.
