Thanks to all who helped me get my documentation for the 18F4520 / 4525 / 4620 when I couldn't get to the Microchip web site. I have made the required changes in the A/D control section & have my IP_Relay product working again. Sort of - - - -=20 I am getting the A/D converter noise reported on this site - I would like to get the Errata sheet for the part, but can't because I still can't get to the=20 Microchip websites by name, as I am still getting the=20 DNS error. I tried nslookup which told me it can't=20 resolve the name. I actually forced a known-good=20 DNS server URL onto the computer, but it also says=20 "can't resolve". This is a problem because I would=20 need that access to get to their download site at=20 ww1.microchip.com, and that gives the good old DNS=20 error. If someone could post the URL to that server I would appreciate it. Baring that, is there any posted work-around for the noise problem? I have tweaked Acquisition Times and Converter clock rates but haven't gotten much of an improvement in the noise. Roy J.
