Prime question is what are you calling the slave unit?
In normal use Lucent treats the Ref-0 unit as the master and Ref-1 as the
slave, but it's Ref-1 that contains the GPS module. Bit confusing but if
you've got Ref-1 with the GPS module then you're in business:-)
It's turned out

It's possible that what you're seeing might well be normal operation when

written confirmation from Trimble that they weren't expecting any rollover
problems with the Ace3, I didn't mention the through the year 2015 comment
as we haven't actually got there yet:-)
That may indeed be an issue
Ah, I took 1999 as I thought that was the only relevant date for another
1024 weeks, I'm not familiar with the shifted 1024 week period so will take a
look at that.
Does shifted imply a shift at the whim of the manufacturer, ie could it
explain why these boards might have been ok a few

Oh well, full credit to Mr Trimble for getting it right, he does bake
exceedingly nice GPS modules and the Ace3 doesn't have a rollover issue and it
does report the date correctly.
Unfortunately, as far as I can tell anyway, the BC637PCI takes the raw GPS
time data from the Ace3 and

It may be that your onboard batteries are in better health than mine are,
although mine might have been disabled using the software, as I tried
booting up without an antenna this evening and got the right year this time
but

What I found when running in GPS
Following my earlier post with download links for the Symmetricom software
and documentation CD TVB was kind enough to send me this Symmetricom
link..

I've verified that the two Windows archives there for the
I played with this around five or six years ago but unfortunately my notes
from that time are likely to be buried somewhere still waiting to be
scanned or indexed.
All the necessary information though is in the user and SDK manuals,
connections for the 10MHz external input and EFC output
Whilst sorting through my BC637PCI files earlier I realised for the first
time that an ISO file I'd downloaded in 2010, described by Symmetricom as
BC635/637 driver, is actually a full software and documentation CD,
presumably what was then being supplied with new hardware.
Ether that or I
The information you need is more in the description of the software
commands, this will tell you how to switch between the internal and external
oscillators and how to vary the conditioning parameters and I'm pretty sure,
although it's been a while so might be wrong, that some of the
My first card at least is a Datum card so quite old now, and that was fine
doing what you want to do..
You really will need to read the manuals in some detail and I do suggest
downloading the larger of the two files I uploaded, that will give you the
latest versions of the Demo programs
Sounds like you cracked it, and beat me to it:-)
I just dug out a PCI expansion chassis, the quickest option for now, and
have one card up and running but have discovered, as a left over from my
playing earlier, that installing the later software, what Symmetricom calls
its BC635/637
I'm not sure I'd want to go quite this far, but here's one option..
