Disable field timecode reporting
This parameter determines how often timecode is reported on the RS422 serial control
port. Some external controllers expect to see timecode once every field of video; while
others expect to see timecode once every frame of video.
Unchecked = timecode reported every field of video.
Checked = timecode reported every frame of video.
Protocol ID
This parameter determines which “Device ID” is sent down the RS422 serial control
port to the controlling device when queried by the controller.
Louth Preview
In VDCP protocol, this command allows clip ID’s to be “pre-cued” in the background,
providing seamless transitions when playing back-to-back clips. If this command is
turned OFF in Mira, there may be frozen video at the end of clips when played back-
to-back.
Unchecked = Preview support turned OFF.
Checked = Preview support turned ON.
Response Time
Fast = best for applications where an operator initiates each action.
Accurate = best for automation systems.
