Does somebody know the signaling with is used between an UPS and a PC ?
Any code fragments are welcome.

Hi Bart,

Assuming that you are using an APC UPS. I found this website
http://www.networkupstools.org/protocols/apcsmart.html which has some of the serial commands documented along with the speed at which you need to talk to it. Hope this helps!

Hello Bret,

Thanks for the reply.

The goal is to simulate a ups by a PIC only to let do the PC a proper shut down.
So, even without the special UPS software on the pc, by mean of the ups settings in control pannel.

But, as you see in the control panel in f.e. XP, you can specifie 3 signals being positief or negatieve.

Anyone has more info ?

Thanks.
