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 blackmark
and a white space. Wasp WLR 8900 series scanners extremely rugged since
theyhaveno 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 byhand byadata entryoperator.
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 sizeof 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 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 varyfrom 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 lowdensity (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.

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. 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 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
sound two beeps.
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: Tohave a minimum length bar code of 1, you must scan a 0 then 1, then scan
the minimum bar code again. Tohave a maximum length bar code of 10, you must scan
a1then 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 strayor 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.”

Preamble/Postamble Configuration
The ‘Preamble/Postamble’ configuration is used to add a prefix or suffix set of
characters to the bar code 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’ bar code on this page.
2) Scan the ‘Preamble’ or ‘Postamble’ bar code.
3) Use Appendix B on pages 31-34 to locate the characters you want to
add as preamble or postamble characters. Make sure that you scan the
bar code associated with each letter before preceding to the next
character. For example, to add the letter “A,” scan the bar code
corresponding to the letter “A” on page 33. The letter “A” will always
appear in your data as prefix or suffix to the bar code value.
4) Scan the corresponding 'Pre/Postamble' bar code on this page to exit
this setting.

The ‘Terminator’ option is used to specify the end-of-text message and is primarily used to
denote the end of the bar code value.
The ‘Code ID’ option sends a specific value when a particular bar code symbology is
scanned. For example, if ‘Code ID’ is enabled and Code 39 is scanned, an “M” will appear
in the data stream in front of the bar code value.

Code 39 is variable length and is the most frequently used symbology in industrial bar code
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 5 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.

Interleaved 2 of 5 is a variable length, even numbered, numeric bar code. 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 5 for information on setting the minimum and
maximum lengths.
