[pos] returns the position [0-6] of the element in the light path. [ready] returns '0' if the element is moving, '1' if it is ready. [step] returns the step position [0-320000] of the element in the light path. [orient] returns the optical orientation of the element in the light path. |
INST |
alfosc |

[step] returns the step position [0-320000] of the element in the light path. [orient] returns the optical orientation of the element in the light path. |
INST |
alfosc |
lamp |
[-d] [position] <n> <m> |
Turns on/off lamp number <n>, <m>=1 is turn on, <m>=0 is turn off. [position] returns a 4 bit pattern corresponding to the state of the 4 lamps. |
INST |
alfosc |
mirror |
[-d] [pos] [ready] <n> |
