Wow there is a tidbit I did not know Ulrich owns Synergy. I knew he was
part of Rohde & Schwartz and I firmly believe that I actually spoke with
him on 2 meters when I lived in CT on the way to work one day. A 2 meter
opening.
OK the total beg right now. Schematics for the FLL board (Not a typo) of
the SMIQ rf generator.
OK that was very on time-nuts. I apologize to the group.
However it is impressive that they did give you the support. Much as others
had in the past.

And while this subject is still up, I want to let the group know that
Synergy *really* went out of their way to help me with this. I was a bit
surprised at their level of commitment to some ham radio operator who had
bought a single unit from them and probably didn't know what the heck he
was talking about. A real class act all around!

Subject: RE: [time-nuts] Synergy-GPS SSR-6tru Problem Resolved
Bob,
Once in a while a mea culpa is required and we're posting it here so
everyone understands our commitment to the users of Synergy's products.
The Original Synergy Adaptor Board was designed to allow Motorola's newer
3 volt 12 channel M12+ to plug into an older 5 volt 8 channel UT+ slot.
That product worked for hundreds of users over the years until (we found
out through your personal aggravation and agony) the recent introduction of
Synergy's SSR series of u-Blox based precision timing boards.
To make sure that the Synergy UT+ Adaptor Board issue is put to bed
properly we asked for an external, formal technical review of this product
that was introduced fourteen years ago.
The reviewing engineer's first comments were "Ouch! This will not work."
And, "no, the SSR boards do not work the same as the M12 boards on the
Synergy Adaptor Board". "The M12+ and M12M receivers have separate serial
ports for the two functions (Receiver command RxD and DGPS RxD input) so it
does not matter what you do with the RTCM port, pin 5 on UT+ connector and
pin 8 on the M12+/M12M connector, if not in use with an M12x receiver."
"The SSR boards, however, had to combine the two serial data streams
expected by the M12x navigation receivers into one because the u-Blox
receiver modules only use one serial input port for both receiver commands
and DGPS correction data. The Synergy Adaptor Boards use a simple gate
combiner circuit that worked well when using the M12+ or M12M but left
Synergy open to this problem when using an SSR. Both serial lines on the
SSR board, pins 2 (Receiver RxD) and 8 (DGPS RxD) are pulled high on the
SSR board so open pins are OK but they must not be grounded."
"The solution is for Synergy to make a UT+ Adaptor Board part number
available to users who only want to test the features of SSR timing
receivers."
That new SSR only Adaptor Board part number, which we'll have available
in a few days, will remove R3 (4.7K) and R4 (6.8K) from the adapter board
and the compatibility issue will be resolved. In the interim, other users
can pull pin 5 of the UT+ connector high (+5V) as you did.
We apologize for the confusion and frustration, Bob, and thank you for
the valuable feedback!
Art Sepin
