Hi guys, do you own or can point to any resources documenting signals on the SLI connector on V2s?
Thanks.

Thanks, but I know this one already. I'm about to design a SLI bridge as a PCB (something like https://sep.yimg.com/ay/outletpc/biosta ... tor-28.jpg) and was wondering if there is anything interesting that could be displayd on the bridge using a simple LED, like SLI_DETECTED etc.

Thanks, anthony, this is already helpful. Do you by any chance have any details for invidual signals? You know, stuff that one would normally find in a datasheet :)

No chance to find datasheet. But with oscilloscope you could explore everything
