Status; Table 5-9. "Get Status" Command Return Data In A "Wheel & Shutter" Configuration - Sutter Instrument LAMBDA 10-B Operation Manual

NOTE: All commands indicated with "*" are not available in early versions of the LAMBDA 10-B (those prior to
Revision D).
The following paragraphs describe the special commands in more detail.

5.4.1 Status

The Status command is used to return information about the filter wheel state (if installed)
and the state of one or two shutters (if, and as, installed). The following tables describe the
type of data and information returned by the Status command. The first table shows the data
returned when the LAMBDA 10-B is in the "Filter Wheel/Shutter" configuration, whereas
the second table shows the status data returned when in the "2 Shutter" configuration.

* NOTE: The length of the status data structure when the LAMBDA 10-B is in the "Wheel & Shutter" configuration is 5 or 6
bytes depending on whether a SmartShutter is connected and, if connected, what mode is it in. If no SmartShutter is installed
or if the SmartShutter Mode is not Neutral Density, then the length of the data is 5 and ends with the return data terminator at
Offset 4. If a SmartShutter is connected and its mode is set to Neutral Density, then the level of neutral density (1-144
microsteps) is present at Offset 4 and the return data terminator is moved to Offset 5.
