I could use a hand troubleshooting a Credo 40 on an RB67 Pro SD.

So here's where I'm at. I've been using the literature here - https://docslib.org/doc/6041532/mamiya-645-df-and-leaf-credo-digital-back-users-guide
to try and get the back to sync with the lens. I've tried the camera mode in Normal and RZ67, shutter latency at each setting of which it's presently at zero, and the phase one sync cable plus Lens mod wake-up cable to the lens; all with no image capture by the back. I've also tried each of the lenses to rule out the sync connector. I'm obviously missing something. I was following the manual as though attaching the back to a tech or large format system since I'm using a manual setup and a dumb adapter. Any ideas on what I'm missing?

I managed to find the culprit. Turned out to be the CF card. It's running as it should now.

The best way to come to a solution is often to post the question... That seems to trigger new inspiration for finding the solution on one's own. I'm glad you figured it out.
