I've got a couple old ELO touchscreens: http://media.elotouch.com/pdfs/manuals/008521_f.pdf https://www.elotouch.com/1545l-disconti ... 2006.html/ They have the RS232 connections not the USB type input and no drivers for ARM. I've tried a couple different DB9 > USB adapters with no luck, but I wouldn't I still have the driver issue. Does anyone know if I can make this work. I might even be persuaded to give you one if there isn't a straight solution, but you believed you could create one. Thanks for any direction Is this the right forum?
