Mike 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?

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.
