+Larry Posted March 23, 2022 Share Posted March 23, 2022 I have two Rev d interfaces, and they both are "losing time" -- several minutes per day on at least one of them. Thus far, there is no loss of settings. I've checked the battery voltage, and it is still >3V in both, so I don't think it is the battery. Have others run into this issue? Since I don't use Sparta, having the correct clock time isn't super important, but clearly there is an issue. BTW, I don't press RESET when on the config screen, so that isn't a problem. Any thoughts? Quote Link to comment Share on other sites More sharing options...
Rybags Posted March 23, 2022 Share Posted March 23, 2022 (edited) Maybe the RTC isn't properly calibrated vs the input clock? Possibly expecting an NTSC master but receiving PAL. Though the difference there over a day would probably equate to a bit over 13 minutes a day. But I'd have thought the RTC would have it's own crystal, especially to be able to work when the computer is off. I've not used mine in a few years and never really kept track of that so can't comment on my own experience.

Simius Posted March 23, 2022 Share Posted March 23, 2022 Several minutes per day means >1000ppm. You need to replace a small crystal next to the RTC chip. It’s 32.768k 1 Quote Link to comment Share on other sites More sharing options...
