My first card at least is a Datum card so quite old now, and that was fine doing what you want to do.. You really will need to read the manuals in some detail and I do suggest downloading the larger of the two files I uploaded, that will give you the latest versions of the Demo programs that allow adjustment of the card, as well as the earlier versions of the same and all the manuals For some things, with earlier versions anyway, it's better to use the BC635 version of the Demo software, as that comes with a built in help section which the BC637 version lacks. I'll try and get a card installed so I can run the software properly again and if so will come back with more information later.

It seems I have first generation of that card. And I was thinking to use that card as a source of 1PPS and 10MHZ - not to feed it from another reference. I though it is possible to do some "modding" to replace VCXO by OCXO.
