Scanner Setup; Scan Speed; Gain Level - Microscan MS-3 User Manual

Scanner Setup

Scanner Setup includes Gain, Scan Speed, Laser Power, and AGC.

Gain Level

Usage: Can be useful for fine-tuning gain or when portions of analog signals
spike, as in the case of specular reflection or extraneous noise.
Definition: Sets a voltage amplitude value for the analog circuitry.
Serial Cmd: <K504, gain
Default: 90
Note: Gain Level is optimized at the factory before shipment; the
default value may not be 90.
Options: 40 to 255

Scan Speed

Usage: To ensure a minimum number of scans, faster scan speeds are typically
used for fast moving symbols and/or longer symbols with larger bar
widths. See
Note: Scan beams move faster across symbols further out in the scan
range since the moving beam is being projected from a spinning mirror.
Definition: Allows the user to set the number of scans per second by controlling the
spinning mirror motor speed.
Serial Cmd: <K500,scan
Default: 50
