I seem to remember back in the day there being combo SDSDI/Composite IO on some devices but I've never run across any 12G SDI IO that was capable of analog anything. It's anecdotal tho, Gary Adams has confirmed the input is only capable of HDSDI.

Program=External, the camera can sync to an SDI source, doesn't need to be "PGM". I've sync'd the cam to other cams as well as a Teranex AV and pulled RP188 from the stream. If it's not locking then there is a frame rate mismatch or other issue in your chain.
Good Luck
