SSR-6t Connector
I had a Motorola M12+ all hooked up with a RF pigtail and data header so I
just unplugged the Motorola and plugged in the SSR-6t.
The data connector was purchased from digikey several years ago and the
details have been lost in the dust.
However it looks like
http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=A33546-ND
I'm unhappy with the one I'm using as the contacts spring pressure is weak
against the connector pin -- I will have to consider looking for a more
"firm" fitting data connector.
The RF pigtail was also obtained years ago from data-alliance.net - their
P3B adapter cable.

Just curious,
what connector/pigtail/adapter board did you use to access the 2x5 1.27mm
pitch connector on your SSR-6T.
Thanks,

Not to hijack the thread. I purchased a ssr and have not rcvd it yet. But
my simple interest is to if needed replace the rcvr in my z3801. There have
been threads on time-nuts that these rcvrs do fail with age.
My belief is that though the connector on the 3801 may be different and it
is 5V, essentially connecting the 1 pps TX RX data and power should allow
this to replace the older rcvr.
Am I on the right track?
As a longer term goal and question does this new rcvr actually improve a
3801s stability?
Thanks

Understood that its 3.3 yup need some regulators but I am hoping I can
essentially drop the ssr into the 3801.

I don't think that will work, Paul. The Z3801 is designed for the VT
receiver and uses commands that are not supported by the M12 or the
SSR. I believe there has been discussion on this in the past.
Now, maybe with a bit of arm twisting, whining and grovelling we could
get Synergy to write an emulator for the VT instead of the M12. Since
they've already done the M12, it might not be a lot of extra work to do
the VT. Of course, an adapter board would be required to deal with the
physical differences. I don't know if they already have one.

Funny you mention the board they do make boards for various units that do
adapt and cover the various voltage translations.

Hi Paul,
I'm pretty sure the hp Z3801A and 58503A/B (and perhaps other 1990's era) GPSDO use the Motorola Oncore VP receiver. It was, and still is, a famous GPS timing receiver. Later, many GPSDO evolved to use the Motorola/iLotus M12 receiver.
The new Synergy SST-6T is a clever combination h/w and s/w that turns a uBlox 6T & PIC into a PCB that is both h/w and s/w compatible with an M12. It's a drop-in replacement. But as such, it won't work in a device that is uses an old Motorola UT/GT/VP receiver.
I suggested that they also come up with a board that is VP compatible, but you realize the number of 15-year-old Oncore VP's in the field is probably not that high. It would make an excellent labor-of-love project to create a VP-compatible uBlox 6T board, but it's probably not something you can make a business case for.

Tom,
Synergy already has a carrier board to put the SSR-6T receiver into a VP, UT,
UT+, etc. socket. All that is needed is firmware support for the old 8-channel
messages. I am planning to implement this capability for Synergy. It's just a
matter of time and priorities. Eventually Synergy will have the solution for
this problem. If you could gather a list of Time-Nuts people who would like one
or more of these and send it to Art that could speed the process along.

Since I have a Z3801A this is an interesting development. Do you expect
to see improved performance or is this simply to replace a dead VP
receiver and bring the Z3801A back to life?
My 6 channel VP receiver was flaky so I replaced it with an 8 channel
model. My Holdover Uncertainty Prediction is now oscillating between a
high of 2 - 3 microseconds and a low of 200 - 300 ns with an oscillation
period of 7-9 days. It's only been running for a few weeks so I'll have
to wait and see if the oscillations die out. Depending on how things
settle, there might not be any need (or room) for improvement.

Hi
The holdover uncertainty prediction is far more a function of your OCXO than of the GPS.

Hi Paul,
I'm pretty sure the hp Z3801A and 58503A/B (and perhaps other 1990's era) GPSDO
use the Motorola Oncore VP receiver. It was, and still is, a famous GPS timing
receiver. Later, many GPSDO evolved to use the Motorola/iLotus M12 receiver.
The new Synergy SST-6T is a clever combination h/w and s/w that turns a uBlox 6T
& PIC into a PCB that is both h/w and s/w compatible with an M12. It's a drop-in
replacement. But as such, it won't work in a device that is uses an old Motorola
UT/GT/VP receiver.
I suggested that they also come up with a board that is VP compatible, but you
realize the number of 15-year-old Oncore VP's in the field is probably not that
high. It would make an excellent labor-of-love project to create a VP-compatible
uBlox 6T board, but it's probably not something you can make a business case
for.

Rick,
Good job on this effort!
Is there any document of the differences between the m12 and SSR-6T behavior on the comm interface? Are all m12 commands implemented for example? Are things like UTC offset implemented?
Thanks,
Said

Synergy already has a carrier board to put the SSR-6T receiver into a VP, UT,

matter of time and priorities. Eventually Synergy will have the solution for
this problem. If you could gather a list of Time-Nuts people who would like one
or more of these and send it to Art that could speed the process along.

Funny
My 3801 has been working fine. But I had read on time-nuts the issues with
the flaky rcvr and thats why I became interested. The 3801s are getting
pretty old. I had to change a 6sk7 in the pre-amp. ;-)

My 6 channel VP receiver was flaky so I replaced it with an 8 channel
model. My Holdover Uncertainty Prediction is now oscillating between a
high of 2 - 3 microseconds and a low of 200 - 300 ns with an oscillation
period of 7-9 days. It's only been running for a few weeks so I'll have to
wait and see if the oscillations die out. Depending on how things settle,
there might not be any need (or room) for improvement.

Hi Bob,
I agree that the HUP is basically determined by the OCXO, but the GPS is
the reference that the OCXO is compared to when determining the HUP. So
it seems reasonable to ask if a better GPS will improve the HUP numbers.
Even with the flaky receiver, my Z3801A was producing 1 PPS signals with
a standard deviation of < 300 ps and a max - min range of about 2 ns.
That was measured over multiple runs of 1000 measurements each. At
those levels, you start to wonder whether the GPS is the limiting factor
or is it the internal architecture and algorithms of the Z3801A itself.

Had a good conversation with Art Slepin at Synergy. He said, if my

for programming, and that it might be possible to do an ONCORE as a
software conversion from the UBLOX to the output connector. Just who is
going to do this, not sure. But it will be possible.
The newer versions of the SST will be programmable through the serial

a UBLOX timer and PIC on the same board might be very cost-effective for

Hi Brent: It's a PIC24J64GA, with 25AA256 external flash, and an AC00
glue chip. The resonator or crystal is apparently 184 A KOX (or K0X),
couldn't get more on it.
Apparently ancient memory did not serve me well about replacing the
ONCORE. As noted earlier by a TN, Synergy may make a piggyback board,
sorry I deleted the message about that, so can't refer to the

the
details have been lost in the dust.
However it looks like
http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=A33546-ND
I'm unhappy with the one I'm using as the contacts spring pressure
is
weak
against the connector pin -- I will have to consider looking for a
more
"firm" fitting data connector.
The RF pigtail was also obtained years ago from data-alliance.net -
their
P3B adapter cable.

Just curious,
what connector/pigtail/adapter board did you use to access the 2x5
1.27mm
pitch connector on your SSR-6T.
Thanks,

Thanks to all who replied with that part number. Come to think of it, if anyone has any (moderately high-res) photos of the front and back of the board, those would be great to see as well.

I'm looking at Synergy's Tech Note #493 for the SSR-6Tr and trying to make out the part number of the PIC from the picture. Looks like it might be a PIC24F part. Would appreciate knowing the actual part number from one of you who's already received your board.

Had a good conversation with Art Slepin at Synergy. He said, if my
ancient memory serves, that the PIC on the new board will be available
for programming, and that it might be possible to do an ONCORE as a
software conversion from the UBLOX to the output connector. Just who is
going to do this, not sure. But it will be possible.
The newer versions of the SST will be programmable through the serial
port. At present, the extra side port on the board is a programming
connector. The info will be on Synergy's SST website. Even at $70 per,
a UBLOX timer and PIC on the same board might be very cost-effective for
all sorts of fooling around!

Hi Paul,
I'm pretty sure the hp Z3801A and 58503A/B (and perhaps other 1990's
era) GPSDO use the Motorola Oncore VP receiver. It was, and still is, a
famous GPS timing receiver. Later, many GPSDO evolved to use the
Motorola/iLotus M12 receiver.
The new Synergy SST-6T is a clever combination h/w and s/w that turns a
uBlox 6T & PIC into a PCB that is both h/w and s/w compatible with an
M12. It's a drop-in replacement. But as such, it won't work in a device
that is uses an old Motorola UT/GT/VP receiver.
I suggested that they also come up with a board that is VP compatible,
but you realize the number of 15-year-old Oncore VP's in the field is
probably not that high. It would make an excellent labor-of-love project
to create a VP-compatible uBlox 6T board, but it's probably not
something you can make a business case for.

Subject: Re: [time-nuts] SSR-6t Connector
Not to hijack the thread. I purchased a ssr and have not rcvd it yet.
But
my simple interest is to if needed replace the rcvr in my z3801. There
have
been threads on time-nuts that these rcvrs do fail with age.
My belief is that though the connector on the 3801 may be different
and it
is 5V, essentially connecting the 1 pps TX RX data and power should
allow
this to replace the older rcvr.
Am I on the right track?
As a longer term goal and question does this new rcvr actually improve
a
3801s stability?
Thanks
