The VERTO series (VERTO32, VERTO64 and VERTO MX) do not work with the “Constellation” series from Blackmagic Designs.   Due to technical limitations of the Constellation devices (No BNC Wordclock out and no Wordclock-Slave-Operation-Mode) these devices do NOT work together with out VERTO devices, because  in Wordclock-Slave-Mode the VERTO needs an external Wordclock, which the Constellation cannot provide. In this case, please use a Pulse16 DX. This device works with the Constellation.
