Some background: The last Revison B hardware shipped in 2008. It used a GPS module manufactured by Sony, which output a sync pulse regardless of it's lock status. Because of changes to the GPS constellation since 2008, these modules have a significantly lower likelihood of having an actual GPS lock, so there is a very good chance you are effectively not GPS synchronized at that site. As a result, I would NOT recommend using a revision B pipe in a live network unless you are absolutely certain it has a GPS lock, and maybe not even then.
We went through several revisions of syncpipes between revision B being retired in 2008 until we released revision H hardware in 2011. That's been long enough ago that I'm not sure which revision caused us to switch to the current GPS module manufacturer (or more accurately away from the Sony modules, and possibly the other supplier of modules we had for a short time), but revision H or later is definitely safe. If someone really needs me to figure this out I will. On Sat, Mar 5, 2016 at 4:00 PM, Mark - Myakka Technologies <[email protected]> wrote: > Putting in a new sync injector for some 450 stuff.
