USB Interface
Introduction
This chapter describes how to set up the scanner with a USB host. The scanner connects directly to a USB host, or
a powered USB hub, which powers it. No additional power supply is required.
The scanner ships with the settings shown in Table 14 on page 228 (also see Parameter Defaults for all defaults).
If the default values suit requirements, programming is not necessary.
Setting Parameters
To set feature values, scan a single barcode or a short barcode sequence. The settings are stored in non-volatile
memory and are preserved even when the scanner powers down.
To return all features to default values, scan Set Factory Defaults on page 59. Throughout the programming
barcode menus, asterisks (
*) indicate default values.
Scanning Sequence Examples
In most cases scanning one barcode sets the parameter value. For example, to set the USB keystroke delay to
medium, scan the Medium Delay (20 msec) barcode under USB Keystroke Delay on page 232. The scanner
issues a fast warble beep and the LED turns green, signifying a successful parameter entry.
Other parameters require scanning several barcodes. See the parameter descriptions for this procedure.
Errors While Scanning
Unless otherwise specified, to correct an error during a scanning sequence, just re-scan the correct parameter.
NOTE: Most computer monitors allow scanning barcodes directly on the screen. When scanning from the
screen, be sure to set the document magnification to a level where you can see the barcode clearly, and
bars and/or spaces do not merge.
