Page 22: Analog Mode Commands
An analog input voltage from 0V to 10V can be used to set the focal power of the lens connected to the CL190. The translation from input voltage to focal power can be linear or can be a non-linear profile. The non linearity is set up by the number of steps in a translation table and the value associated with each. - Page 23 CL190/CL191 Lens Controller - User Manual Set analog translation Non-linear translation can be used to convert the analog voltages from a distance sensor to an optical power to focus at the given distance. This command turns on non-linear translation and sets the number of steps in the non-linear translation.
