state is mutually exclusive, meaning that for any LED that is turned on, all other LEDs are
turned off.
NOTE: It is recommended that the compatible Lambda 10 series filter wheel movement
commands are sent to the Lambda 721 only while in Lambda 10 Mode.

NOTE: All Lambda 10 Mode commands for the Lambda 721 correspond to the Lambda 10 series filter wheel
movement for Wheel A, Speed 0, Positions 1 – 7. Any other wheel-select, speed settings, and positions 8 – 9 are not
supported. Values 1 through 7 correspond to LEDs 1 – 7. Value 0, used to turn all LEDs off, can be used as the
equivalent of closing Shutter A.
While in Lambda 10-x Mode, the Lambda 721 will also respond ASCII digits 0 through 7, as
equivalents to values 0 through 7 (see the next table). (These are equivalent to the Lambda
10-x Series commands for Wheel A, Speed 3, Filter Positions 0 through 7.)
