Select Symbologies
This item allows the user to program the SV unit to enable/disable individual symbology
decoders. This is useful for either more secure decoding or sometimes faster throughput if a
single symbology type is always being analyzed.
Select Comm Port
This item allows the user to select a comm port in the host PC.
Change Verifier Baudrate
This item allows the user to program the SV scanner/verifier baud rate.
Match Verifier Baudrate
This item allows the user to allow ScanVision to detect and match the baud rate of an SV
scanner/verifier. This is useful when using ScanVision as a diagnostic tool in a system that is
using the SV communication interface. ScanVision can easily be inserted in the system without
re-programming the SV serial port, therefore when re-connecting the SV unit back to the host, all
communication parameters remain compatible with the host.
Minimum Codes Per Sync
This item allows the user to program the minimum number of bar codes expected in a sync
interval. This parameter is important for detecting No Read conditions.
Ladder Mode and Picket Fence Mode
These items allow the user to program the SV unit to scan bar codes travelling in either “picket
fence” or “ladder” direction. “Picket fence” orientation is defined as the bar code travelling through
the laser beam in the direction of the height of its bars. “Ladder” orientation is defined as the bar
code travelling through the laser beam in the direction of the beam path. NOTE: In cases where
the SV is scanning bar codes statically placed in the beam, the “picket fence” direction
must be used.
Advanced Menu
This menu is an extension of the Setup Menu, providing less commonly used, but useful SV
system features.
Toggle Display Updating
This item enables/disables display updates in real time. Disallowing updates is useful to allow
ScanVision to keep up with a high throughput application.
Toggle Additional Results
This item enables/disables additional analysis parameters to be displayed on the Bottom Panel of
the Bar Code Analysis Screen. The additional parameters are intended for debug use only while
working with PTX Technical Support.
Static Codes Mode
This item allows the user to set the SV to scan and analyze bar codes placed statically (not
moving) in the laser beam.
Moving Codes Mode
This item allows the user to set the SV unit to scan and analyze bar codes that are moving
through the laser beam.
Download New Firmware
This item is used for updating the firmware revision level in an SV scanner/verifier.
