Setting Up the Verifier with ScanVision
Use RJS ScanVision software to set up verifier by taking a Scan Profile
(Reflectance).
Installation of the verifier requires proper mounting position, port
configuration(s), and LED configurations to ensure reliable and accurate
operation.
1. Install the verifier at the proper distance and angle. See “Installing
the Verifier” in Chapter 2 for more information.
2. Connect the cables. See “Connecting the Cables” in Chapter 2 for
more information.
3. Run the ScanVision software.
4. Set the verifier for parallel bar code travel direction.
5. Place a sample bar code in the center of the intended laser beam
path. For best results, this sample should match
the type of bar code(s) and material that is to be
analyzed in the final application.
6. Knowing the X dimension (narrow element width)
of the bar code(s) is a big plus. Refer to the
Packet Reference Manual (on the Tabletops
Documentation CD-ROM) for more information.
For example, this I2of5 bar code has a density of 12 and an
X-dimension (narrow element) of 9.9 mils.
Note: The Calibration label has a 10 mil X dimension unless otherwise
indicated.
7. Take a Scan Profile (Reflectance) with ScanVision by clicking
.
Refer to the SV Series Operator’s Guide for more information:
a) The bar code(s) should be in the center of the scan path.
b) The scan profile should not contain distortions from light
reflecting from objects in or near the light path. One major
aspect in a good profile is the low reflectance points (the
bars) in the symbol are uniform all the way across the code.
