Hi Jacques,
I’ve bought three of these PRBB for my PRS10s and got none of the information that you are interested in supplied by SRS.
As you are asking for the Cannon connector used, I presume you don’t have one and maybe want to make one up?
I have removed one and confirm that the Cannon connector is that described in the Operation and Service manual.
Unfortunately the parts are not in that manuals parts list.

The connectors on mine are marked DAM-11WSM-A197

You can get both that and the coax connector insert,DM53740-5008,  from Digikey for instance. Note the 2nd M is not in the Digikey reference.

Conceptually it looks pretty simple, with 10MHZ and 1PPS IN being just passed through and the data signals being inverted with a 74HC14D.
So there is no full RS232 conversion, limiting cable length probably.
The 1LOCK/1PPS OUT signal through Cannon pin 1 appears to be double inverted before being fead to the BNC, to enable a LOCK lead to be lit as well as having the positive going  but narrow pulse.

I searched Digikey for the canon connector but could not find it... they do have the coax insert part number you listed.  Are you aware of any other source for the entire connector?

Hi

Any time I’ve bought those connectors, it has been as shells, bodies, and inserts. You buy the bits and
peces to put together. The reason is fairly simple. There are multiple “big fat” inserts that can
go into them. Shells come a lot of ways. Coax, and various high current contacts are the fairly normal inserts.
There are some really exotic inserts as well. In some cases, the bodies are a “14 week back order / minimum
quantity per order” sort of thing.

I couldn’t find the entire connector anywhere.
The unpopulated D-Sub Digikey id is DAM-11W1SM-A197 (sorry, I had dropped the 1)
I couldn’t find a european distributer. Mouser has no stock.
