    We are using a photo lens on a Blackmagic Ursa on the Movi Pro. Since the photo lens does not have an iris ring, we are using an external Arduino to control iris via the camera electronics.

    Is it possible to either read the position of the iris wheel via the Aux Data Out port on the Movi Controller? Or even better, is it possible to read the iris state from the Movi COM port and pass it to the camera via the Arduino (even without a motor hooked up to the Movi)?

    Does anyone have any experience with this?

    Apparently the API is not meant for the Movi Controller, at least according to my latest contact with Freefly Support. (Support for the COM ports on the Movi or the Mimic only—"The API documentation does not list the MoVI Controller")

    However, the AUX Data Port can explicitly be configured for "API Access" using the menu on the Movi Controller. Also, third party products like the 1A wheels are already interfacing with the Movi Controller via the Aux Data Port.

    Does anyone have any information on what sort of connection the port uses. I suspect that it is some kind of serial connection, but cannot quite figure out how to use it?
