Optical encoders and geared mountings: possible info overload?

Hi all,

Here I'm exposing my ignorance of electronics with the following question:

Gears I know can be used to increase or decrease the number of revolutions an element is caused to rotate. Now, as an optical encoder punches out information at a particular rate to a cpu, say one running DSCs, is it possible to create a gearing ratio that can overload the cpu?

As an example, say the optical encoder I'm using has a resolution of 2048, and is connected to azimuth of a dob mount, and the effective geared ratio is 8:1, 8 encoder revolutions per one rocker box revolution, would I be oveloading the cpu of the DSC? If not, then this could give me an effective encoder resolution of over 16,000.

Yours in ignorance,

Mental.
