Please Read
Note:
The Wasp®WLR8900 Series Scanners
are ready to scan the most popular barcodes out of the box.
This manual should only be used to make changes in the
configuration of the scanner for specific applications. These
scanners do not require software or drivers to operate. The
scanner enters data as keyboard data. Please review this manual
before scanning any of the programming barcodes in this manual.
Tech Tip
If you are unsure of the scanner configuration or have scanned
the incorrect codes, please scan the default barcode on page 7.
This will reset the scanner to its factory settings.

Introduction
Barcoding 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 barcodes is almost negligible and can be error-free using barcode
symbologies with the check digit enabled.
The Wasp Charged Coupled Device (CCD) technology is a technique
whereby a barcode 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 WLR8900 series scanners
extremely rugged since they have no moving parts. Wasp WLR8900 series
scanners are support PS/2 or USB keyboard interfaces and easily wedges
between the computer and keyboard. Barcode 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 barcode scanning devices on the market, the CCD
reader is the easiest to use and most cost effective for the typical business
user. The Wasp WLR8900 series scanners are extended distance scanners
with a depth of reading of up to one foot depending on the mil size of the
barcode. To activate the scanner, the user simply points the scanning
aperture towards the barcode, pulls the trigger, and aims the red LED
beam across the barcode.

Barcode Symbologies
Barcodes 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 barcode is dependent on the narrowest element of a
barcode (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
WLR8900/8905 Scanners can read barcodes with X-dimensions as low as
5 mils (0.005 in/0.13mm).
Wasp WLR8900/8905 Scanners can read the most popular barcode
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.
Please see test chart on pages 29-31.

Quick Start
Your Wasp WLR8900/8905 Scanners are ready for use. The default
settings of the scanners have been pre-programmed for the most common
bar code configurations. Use the “WLR8900/8905 Setup & Configuration”
sections only to customize the scanners settings. Please review the
“Enable Barcode Symbologies” configuration beginning on page 14 to see
the list of barcode symbologies which are enabled by default.
Tip:
• Use the pre-printed “Barcode Test Symbols” in Appendix A on pages
29-31 as a test chart to practice scanning.

Setup & Configuration
In order to configure Wasp WLR8900/8905 Scanners, you must familiarize
yourself with the setup procedures on the following pages. The default
settings of the Wasp WLR8900/8905 Scanners are identified on each page
and clearly marked using an asterisk (*). The default settings have been
preprogrammed for the most common barcode configurations. Use the
Setup & Configuration only to customize the Wasp WLR8900/8905
Scanners settings. If you need to configure the scanner, the default
settings will be 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 WLR8900/8905 Scanners
is removed by turning off your PC.
In order to configure Wasp WLR8900 Series Scanners,
two basic steps need to be followed:
(1) Locate the group that contains the options to be changed.
(2) Scan the barcode representing the option to be changed.
The scanner will sound two beeps.
To change Minimum/Maximum Length:
(1) Scan the Minimum or Maximum Length barcode.
(2) Scan a 2 digit value from the ASCII table on pages 32-35
(3) Scan the Minimum or Maximum Length barcode again.
Example: To have a minimum length barcode of 1, you must scan a
0 then 1, then scan the minimum barcode again. To have a maximum
length barcode of 10, you must scan a 1 then 0, then scan the
maximum barcode again.

The 'Beep and Delay' configuration supports the general control options
for the Wasp WLR8900/8905 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 barcode, if some stray or scrambled characters appear,
increase the intercharacter delay to slow down the transfer rate.

• 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.”

The ‘Preamble/Postamble’ configuration is used to add a prefix or suffix
set of characters to the barcode value. Up to 8 characters may be added
for each option separately. Preamble and postamble characters can
function concurrently, but need to be configured separately.
To add preamble or postamble characters, follow the steps below:
1) Scan the ‘Clear Pre/Postamble’ barcode on this page.
2) Scan the ‘Preamble’ or ‘Postamble’ barcode.
3) Use Appendix B on pages 32-35 to locate the characters you want to
add as preamble or postamble characters. Make sure that you scan
the barcode associated with each letter before preceding to the next
character. For example, to add the letter “A,” scan the barcode
corresponding to the letter “A” on page 34. The letter “A” will always
appear in your data as prefix or suffix to the barcode value.
4) Scan the corresponding 'Pre/Postamble' barcode on this page to exit
this setting.
