* NOTE: The block of data returned by the Get Status command will vary in length depending on whether neither, either, or
both SmartShutters (A and/or B) is/are in Neutral Density mode. All modes are followed by an additional byte indicating which
device to which the mode pertains (1 = Shutter A and 2 = Shutter B. When Neutral Density mode is selected, a third byte exists
that contains the number of microsteps (1 – 144) used to indicate the Neutral Density level. The following table outlines the
characteristics of the status block of data according to the mode of each of the two SmartShutters.

SmartShutter A not connected:
Indicates either that no
SmartShutter is connected, or a
Vincent shutter is connected.
Fast Mode
Soft Mode
Neutral Density Mode
Device designator: Shutter A
A third byte contains the number
of microsteps (1 – 144).
NOTE: The number of neutral
density microsteps is present at
this byte offset only if Shutter A
Mode is set to Neutral Density
(Offset 3 = 222 (0xDE)).
SmartShutter B not connected:
Indicates either that no
SmartShutter is connected, or a
Vincent shutter is connected.
Fast Mode
Soft Mode
Neutral Density Mode
Device designator: Shutter B
A third byte contains the number
of microsteps (1 – 144).
NOTE: The number of neutral
density microsteps is present at
this byte offset only if Shutter B
Mode is set to Neutral Density
(Offset 5 or 6 = 222 (0xDE)).
