Hi everyone, First of all, I thank you for all your response.
I understand the best solution would be using an IRIG board and that's what we had been using. We are now trying to make our product more compact by using a small single board PC with no RS 232 or PCI slot (no slot at all). Currently I am using GPS antenna with a USB connection. I also understand that if I can get a small PC with one genuine RS232, I can use Dave Hart's solution as tested by David. I will try to my best to steer the project towards this direction. Right now, I am trying to find the best GPS antenna that outputs at a consistent pace (better if the output can be configured so I only receive time stamps). Any recommendations wrt that? Thanks again. Jack On Mar 10, 4:59 am, Martin Burnicki <[email protected]> wrote: > Jack, > > jack wrote: > > Hi all, > > > I am trying to sync my Windows box to an external GPS source.
