You'll want to learn Eagle eventually
So you can make a single board with a few jumpers to do both ends eh?_____Rob
Unless you want to wait for another Linux/Kicad user to come along (good luck with that), you should probably post files that the other 98% of the world can view.
Your best off posting in PDF or possibly JPEG.If I see a PDF schematic I will often view it sinceit is quick to do and requires a viewer the browseralready recognizes.If I see a schematic in Kicad/Eagle/.. etc I can'tview it.(* jcl *)
While Graynomad is chewing his arm off, I threw together what I think would make a nice little universal RS485 3-channel driver/receiver board. The same board should work at each end. The solder bridges let you "hardwire" the channels for send or receive. And you can select several different power options for the send or receive ends. (Remember that 7805 is symmetrical and can be inserted in either direction depending on what you need.) I don't have time to do the board layout until tomorrow, but here is my proposed schematic.
