Sony FX9 recording codec assistance

[Davester]

I shoot a lot of sports and ESPN still insists on shooting 1280x720 29.97.  I switched from the FS7 to the Sony FX9 and can't seem to figure out how to switch the camera to that codec and get it to output from the BNC SDI connector on the rear of the camera so it can go to my TVU or LiveU.  Can anyone provide me a detailed walk thru to achieve this end?  Thanks!

I don't think it's possible to record or output 1280x720 with an FX9. Except with the proxy feature.
