DT has developed this as a temporary workaround to use until Phase One ships the new IQ4 multiport-to-sync cable and firmware that supports it. For most kinds of imaging the sensor-based electronic shutter (ES) can be used instead of the Copal shutter. Exceptions include working with strobe on a tech camera, where the flash sync speed of the copal shutter is often required for the correct exposure. Phase One knows this new cable and the firmware are important; we expect both in the next few weeks – DT has already received a prototype to begin testing; they just weren't ready in time for the first wave of shipments.
You can read the setup, procedure and other details here: DT Copal Shutter Workaround for Phase One IQ4 150mp on tech cameras (https://www.dtcommercialphoto.com/dt-copal-shutter-workaround-for-phase-one-iq4-150mp/).
This workaround should work for shutters other than Copal, but that has been the focus of our testing.
