(My first response was moderated because of replying to too many
recipients? Apologies if this a duplicate.)

Can the shutters be controlled via ethernet or serial port? If so, it
wouldn't be difficult to rig up a DMX-to-Ethernet/Serial converter using a
Raspberry Pi or BeagleBone Black running Open Lighting Architecture (OLA -
https://www.openlighting.org/) and some Python glue. It would be a perfect
student project.
