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 barcodes 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 WLR8950 series scanners are extremely rugged since they have
no moving parts. Wasp WLR8950 series scanners 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 WLR8950 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.

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 WLR8950 Scanners can read barcodes with X-dimensions as low as 5 mils (0.005 in/0.13mm).
Wasp WLR8950 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.

Use the Factory Default barcode to reset the scanner to the Default settings.
Factory Default
In order to configure Wasp WLR8950 Scanners, you must familiarize yourself with the setup procedures on the following pages.
The default settings of the Wasp WLR8950 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 WLR8950 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 WLR8950 Scanners is removed by turning off your PC.
In order to configure Wasp WLR8950 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 27-30.
(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
The ‘Beep and Delay’ configuration supports the general control options for the Wasp WLR8950 Scanners. These options include the
tone, intercharacter delay, and interblock delay. The High, Low and Med settings refer to the tone of the beep, not the volume.
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.

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.

PREAMBLE/POSTAMBLE , TERMINATOR AND LABEL TYPE
*Default
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 27-30 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”. 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 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.

Interleaved 2 of 5 is a variable length, even numbered, numeric barcode.
It is typically used in industrial and master carton labeling and also in the automobile industry. The symbology uses bars to represent
the first digit of a pair and the interleaved (white) spaces to represent the second digit of a character pair.
See page 7 for information on setting the minimum and maximum lengths.
Code 93 encodes the full 128 ASCII character set using 9 modules arranged into 3 bars with adjacent spaces. Two of the characters are
check characters. Code 93 is similar to Code 39 but encodes more characters per inch.
