Introduction

Bar coding is the most common Automated Data Collection (ADC) technology providing timely, error-free information that can be used to increase productivity, accuracy, and efficiency in the workplace. Virtually every type of industry is using bar codes to replace keyboard data entry. Studies have shown that a proficient data entry operator will make one error for every 300 characters that are manually entered. The error rate using bar codes is almost negligible and can be error-free using bar code symbologies with the check digit enabled.

The Wasp Charged Coupled Device (CCD) technology is a technique whereby a bar code is photographed, digitized, and electronically sampled by built-in photodetectors. The detectors process the measurement of every bar and space using the number of adjacent photodetectors which contrast a black mark and a white space. Wasp WLR 8900 series scanners extremely rugged since they have no moving parts. Wasp WLR 8900 series scanners are support PS/2 or USB keyboard interfaces and easily wedges between the computer and keyboard. Bar code data is passed directly into the keyboard buffer as if it had been typed in by hand by a data entry operator.

Of all the hand held bar code scanning devices on the market, the CCD reader is the easiest to use and most cost effective for the typical business user. The Wasp WLR 8900 series scanners are extended distance scanners with a depth of reading of up to one foot depending on the mil size of the bar code. To activate the scanner, the user simply points the scanning aperture towards the bar code, pulls the trigger, and aims the red LED beam across the bar code.

Bar Code Symbologies

Bar codes are symbols consisting of a series of bars and spaces which can be applied to packages, cartons, bottles, and other commercial products. The bars and spaces in each symbol are grouped in such a way to represent a specific ASCII character or function. The interpretation of these groups is based on a particular set of rules called symbologies. Various symbologies have been developed for particular applications. Some examples are shipping and receiving, manufacturing, retail, healthcare, transportation, document processing and tracking, and libraries.

The resolution of a bar code is dependent on the narrowest element of a bar code (X dimension), and can vary from high density (nominally less than 0.009 in./0.23 mm), medium density (between 0.009 in./0.23 mm and 0.020 in./0.50 mm), and low density (greater than 0.020 in./0.50 mm). Medium and low densities are the most common since these are the easiest to read (scan) with nearly all scanning devices. Wasp WLR 8900/8905 Scanners can read bar codes with X-dimensions as low as 5 mils (0.005 in/0.13mm).

Wasp WLR 8900/8905 Scanners can read the most popular bar code symbologies including Code 39, Code 93, Code 128, Interleaved 2 of 5, UPC-A, UPC-E, EAN/JAN-8, EAN/JAN-13, Codabar, and MSI/Plessey.

Quick Start

Your Wasp WLR 8900/8905 Scanners are ready for use. The default settings of the scanners have been pre-programmed for the most common bar code configurations. Use the “WLR 8900/8905 Setup & Configuration” sections only to customize the scanners settings. Please review the “Enable Bar Code Symbologies” configuration beginning on page 14 to see the list of bar codes symbologies which are enabled by default.

Tip:

• Use the pre-printed “Bar Code Test Symbols” in Appendix A on pages

28-30 as a test chart to practice scanning.

Setup & Configuration

In order to configure Wasp WLR 8900/8905 Scanners, you must familiarize yourself with the setup procedures on the following pages. The default settings of the Wasp WLR 8900/8905 Scanners are identified on each page and clearly marked using an asterisk (*). The default settings have been preprogrammed

for the most common bar code configurations. Use the Setup & Configuration only to customize the Wasp WLR 8900/8905 Scanners settings.

overwritten. All the programmed settings are stored permanently in non-volatile memory; therefore, your configuration will be maintained even if the keyboard power to Wasp WLR 8900/8905 Scanners is removed by turning off your PC.

In order to configure Wasp WLR 8900/8905 Scanners, two basic steps need to be followed:

(1) Locate the group that contains the options to be changed. (2) Scan the bar code representing the option to be changed. The scanner will

To change Minimum/Maximum Length:

(1) Scan the Minimum or Maximum Length bar code. (2) Scan a 2 digit value from the ASCII table on pages 31-34 (3) Scan the Minimum or Maximum Length bar code again.

Example: To have a minimum length bar code of 1, you must scan a 0 then 1, then scan the minimum bar code again. To have a maximum length bar code of 10, you must scan a 1 then 0, then scan the maximum bar code again.

Beep and Delay

The 'Beep and Delay' configuration supports the general control options for the Wasp WLR 8900/8905 Scanners. These options include the volume, intercharacter delay, and interblock delay.

Interblock delay is the minimum time interval between two adjacent scans. If the processing speed of your host device is slower than your scanning speed, a longer interblock delay may ensure the data integrity.

Intercharacter delay is the time period that the scanner will wait before transmitting the next character. If data sent by the scanner has incorrect or missing characters, a longer intercharacter delay may solve the problem. The intercharacter delay should be changed only if the transfer rate cannot be maintained between the scanner and the keyboard buffer of the computer.

Note: The default for the intercharacter delay is set to '140us' and is the most common configuration; however, your PC may be different. When you scan a bar code, if some stray or scrambled characters appear, increase the intercharacter delay to slow down the transfer rate.

Upper/Lower Case

• Caps Lock Auto (For PC XT/AT only):

In Auto Trace mode, the scanner will keep track of the Caps Lock status automatically. For some PCs, the scanning performance may be compromised because of the auto tracing. If the scanning performance is poor (or cannot scan) or the scanner cannot output the upper/lower case characters correctly, try to select one of the next two choices instead of auto tracing.

• Caps Lock Off:

When the keyboard is in the unshifted state (Caps Lock is not pressed), select “Lower Case.”

• Caps Lock On:

When the keyboard is in the shifted state (Caps Lock is on), select “Upper Case.”
