Miscellaneous Commands
Gain Control
Command:
GC
Purpose: Determines what receiver channels are used to decode
barcodes. The BA-440 DualBeam processes the barcode
data using two channels, one for Lo gain and one for Hi
gain. New, bright decals have a strong signal and are
processed successfully on the Lo gain channel. Older, less
reflective decals can have a very weak signal that requires
processing on the Hi gain channel to be read.
Options: [Both], Lo, Hi
Example:
GC Lo
Be careful when changing this parameter. Setting the Gain Control to
the Lo channel only may prevent older or damaged decals from
reading while still picking up newer ones. Setting the Gain Control to
the Hi channel only may prevent newer decals from reading while
picking up older ones. In general this parameter is used to
troubleshoot problems and should not be changed without direction
from BAI.
If the setting is changed the technician will need to observe a large
number of vehicles passing the reader to determine if barcodes are
being read successfully.
