Chapter 1
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.

Chapter 2
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.

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.

BEEP AND DELAY
Chapter 5
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.

UPPER/LOWER CASE
Chapter 5
• 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.”

PREAMBLE/POSTAMBLE CONFIGURATION
Chapter 5
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.

CODE 39 SETTINGS
Chapter 5
Code 39 is variable length and is the most frequently used symbology in
industrial barcode systems today. It is extensively used within the
Department of Defense (DOD). The principal feature is to encode
messages using the full alphanumeric character set. Standard Code 39
contains only 43 characters (0-9, A-Z, $, /, %, +, -, ., SPACE) and can be
extended to a 128 character symbology (full ASCII) by combining one of
the special characters (S, /, %, +) with a letter (A-Z) to form the characters
that are not present in the standard Code 39 symbology.
See page 6 for information on setting the minimum and maximum lengths.

This warranty applies to the original owner and does not extend
to any product which has been subject to misuse, neglect,
accidental damage, unauthorized repair, or tampering.
No other express warranty is given. The replacement or repair of a
