Microscan MS-860 User Manual page 110

Raster Sweep Rate
Usage: If your application allows it, a slower sweep rate can produce more
scans per second and higher read rates. To determine the minimum
read rate for your application, see
on page A-21.
Definition: The raster sweep rate is the number of sweeps per second the raster
mirror completes. A sweep is one pass of the raster, up or down. The
maximum sweep rate is limited by the size of the arc the raster must
move through.
Serial Cmd: <K506,raster status,top offset,bottom
cycle on/off>
Default: 10
Options: 0 to 80.
To maximize the number of scans per symbol, use the lowest effective
sweep rate required for the application.
Important: The MS-860 is physically different from the MS-850 in trigger polarity and
the calculation of raster sweeps.
Read Cycle On/Off
Usage: This feature should only be used when the raster sweep rate is at least
twice the required trigger rate (decoded outputs per second).
Definition: When Read Cycle On/Off is enabled and Laser On/Off is also enabled,
the raster mirror stops at top offset at the end of triggered read cycle.
Serial Cmd: <K506,raster status,top offset,bottom offset,raster sweep
on/off>
Default: Disabled
Options: 0 = Disabled
