The VMM-D1 shutter controller (or a single shutter on a VMM-D3 controller) can be controlled directly by Openlab.

To control multiple shutters on the VMM-D3 controller:

Plug the serial cable from the controller into one of the serial ports on the computer or adaptor. Within Openlab got to the Edit menu, choose "Preferences" and select the serial ports preference. Assign "Automator Serial Comms" to the port the shutter controller is plugged into. Double click on the text "Automator Serial Comms". The default settings for this controller are as follows.
