I need to build my own Mac Serial (RS-422 Mini-8) to USB dongle.
The ideal solution will not require any special drivers (or if any are needed, then they must be pretty small in size.
I am finding specs for 422 to RS-232 and RS-232 to USB, but the latter requires usage of certain chips from vendors and I was hoping to keep my final product to something simple or to a single small micro since I have a space constraint.
Google is not my friend tonight. Anyone been down this road before?
