Hello,
I have lurked around for some time now, but need some help from the vast expeiance available here.
I have designed a board that will allow me to comunicate with the Advantech PCLD-785B and PCLD-782B through an RS485 interface. They are basically isolated IO boards, available on e-bay for cheaper than I can make them. This is my first real PCB design. I did this as a route to have a number of isolated IO available to be contolled through my PC. I am about the send the PCB (Drawn in eagle 6.2) to a fab house (iteadstudio.com). I would appreciate a quick review by anyone who has some free time to see if there are any issues that I should correct before forking out the cash.
Areas that I have the most concern about are the crystal osciallator set, and the ground planes. Also should I add some VIA's between the ground planes in general, or is it really worth while?
If you are willing to spend a few minutes to have a last look for me I can send you the eagle files. I consider this project to be open source, and free.
