Operation of Database

Operation of Database

Once Configuration Database is enabled (by setting the Number of Active Indexes
to any number other than 0) the reader's current settings for Gain, AGC Mode, Track-
ing, Raster Top, Raster Bottom, Raster Speed, Laser Framing Status, Laser On
Position, Laser Off Position, Laser Power and Background Color will no longer
impact reader operation. For those parameters, only settings that are in the database
and enabled will be used during the normal read cycle.
Number of Active Indexes
Definition: Number of data base records (groups of settings) that will be used auto-
matically during the read cycle. If set to 0, the reader only uses the cur-
rent settings, not database entry settings.
Serial Cmd: <K252,number of active
Default: 0 (0 = disabled)
Options:
0 to 10 indexes
Database Cycles
Definition: The number of times the database will be repeated (cycled).
Serial Cmd: <K252,number of active
Default: 0
Options: 0 to 255
When set to 0, the reader will repeatedly cycle through all active database indexes until
the read cycle ends. When set to any number greater than 0, the reader will only cycle
the active database entries the defined number of times before adopting the settings
from the last active index for the remainder of the read cycle.
Note: It is possible for the read cycle to end before the reader is able to cycle trough all
data base entries.
Note: When the reader is in Continuous Read and Continuous Read 1 and not in
Read Rate, it will only use current settings, not database entry settings. However, the
user may still send the
base.
