Post by thread:[pic] UPS / APC Smart Protokoll

Hi all, I want to build some kind of UPS using the APC smart protokoll with a pic with intergrated USB2.0 port. I am looking for a godd description of the protokoll itself. Does anyone has a assembler code or even a link for that? Thanks Jens

The best info I've seen on the APC SmartUps protocol is at http://www.networkupstools.org/protocols/apcsmart.html Dan

Thanks, there is much information, but only about RS232 connections. I want to do that by USB. Is USB used only for "RS232-Emulation" at APC? Or is it a real USB-connection? RS232 over USB would make it much more complicate in Software, or much easier, when using USBtoRS232 converter in front of the PIC ... APC seems to be badly documentated ...
