Definition: Sets a voltage amplitude value for the analog circuitry.

spike as in the case of specular reflection or extraneous noise.
Caution: Changes to Gain are typically done by qualified technicians in
Autocalibration. See Chapter 6, “Autocalibration.
Serial Cmd: <K504,gain,tracking>
Default: Default is 40 (nominal). Gain is optimized at the factory before ship-
ment; the default value may not be 40.
Options: 0 to 255
Definition: Tracks peak signals and selects an amplitude reference point to sample
the analog signals for converting to digital.
Usage: Useful in fine-tuning tracking or when conditions of poor contrast or

Caution: Changes to Tracking are typically done in Autocalibration.
See Chapter 6, “Autocalibration.
