CL190/CL191 Lens Controller - User Manual

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. The commands are described below:
Set analog mode
This command sets the output to analog mode so that the optical
power is set by an analog input voltage. The translation from input
voltage to focal power would normally be set before sending this
command.
RA1,0
Turn off analog translation
This command turns off the non-linear translation (enables linear
relationship), so that an input of 0V gives the minimum optical power
of the lens and 10V gives the maximum optical power of the lens.
RA1,1,0
This gives the following relationship:
