RS485 to Advantech PCLD-785 / 782 final review
« on: November 24, 2012, 19:02:03 PM »
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. This is my first "large" design ever, I have made a few simple PCB's in the past. 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?

I consider this project to be free and open, if you want to utize any of it, just ask, I can send you all the doccumentation.

For some reason i cannot open it with eagle 5.11... Which version you use?

Also, if you want, i can host this project in my site when you are ready

Hello I have converted the layers to a .png however I can't upload them for some reason.

I use eagle 6.2.0 I guess they are not backwards compatable. Thanks for the offer of hosting, I will probably take you up on that. What is your site? maybe i can just send you the files, and update them as I work on it.

Every needless upgrade is not for good... 5.1 works well for me and i do not want to take any chances these days, but i will certainly go to 6 next year.

Awesome, I will let you know in a couple days when I have finished everything up. The source code is still a work in progress, but it is fully functional. I am just debugging right now.
