Scanners and Imagers
The VH10 supports a wide range of scanner options to address a variety of user application requirements.
Decoded scanners must be configured by scanning special configuration barcodes. In these cases, the
scanner manufacturer provides programming manuals for configuration purposes. Refer to the following
sections for detailed information:
•
Supported Types: Handheld scanners and imagers connected via USB, RS-232, or
Bluetooth
, see
“External Barcode Scanners” on page A-5.
•
Interface: FF UART RS-232 port or USB port, see Appendix B: “Port Pinouts”.
•
Configuration: “Scanners” on page 82 and “Manage Triggers” on page 66.
•
“Scanning Techniques” below outlines the mechanics of a successful scan.
•
“Troubleshooting” below provides some helpful suggestions should the scan fail.
3.5.1
Scanning Techniques
•
Hold the scanner at an angle. Do not hold it perpendicular to the barcode.
•
Do not hold the scanner directly over the barcode. In this position, light can reflect back into the scan-
ner’s exit window and prevent a successful decode.
•
Scan the entire barcode. If you are using a 1D or PDF laser scanner, make certain that the scan beam
crosses every bar and space on the barcode, including the margins on either end of the symbol.
•
If you are using a 2D imaging scanner, make certain the red, oval shaped framing mark is centered
within the barcode you want to scan.
•
When using imaging scanners, do not move the scanner while decoding the barcode. Movement blurs
the image.
•
Hold the scanner farther away for larger barcodes.
•
Hold the scanner closer for barcodes with bars that are close together.

scanners described in this chapter.
