The bottom one referred to on Didier's site is the old Windows 3 version,

The later version is the one marked Satstat50, actually SatStat 5.0 and a

Hi Paul
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 possible that what you're seeing might well be normal operation when
they're operating as a pair, since Ref-0, what we've been calling the slave
because it has no GPS receiver, is actually the default "master" in
operational terms.
I only have Ref-1 units operating stand alone so

Oh well, and perhaps not too surprisingly, the J5 pin 3 to ground option on
its own was not that much of a raging success.
However, the unit did eventually come up indicating "Standby", and at that

Arthur, I've only just had a chance to look at your latest photos, and

your links on J5 are not shown on pins 2, 10, 12, and 15, but on pins 4, 6,

As far as I'm aware t

Hi Arthur,
Thanks for the extra information, it sounds like you may well have answered
my question:-)
As I commented to Bob, I was hoping I might be able to find an option that
didn't require any internal access, I knew that was a long shot anyway but
I quite liked the idea of a plug and
you won’t be able to see any result
of that.

In my case, I do need the 10MHz, so I'm just as happy to have bought both
