Programming Guide
Please Read
Note:
The Wasp WCS 3900 / 3905 Scanners are ready to scan
the most popular bar codes out of the box. This manual
should onlybe 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
bar codes in this manual.
TechTip
If you are unsure of the scanner configuration or have
scanned the incorrect codes, please scan the default
bar code on page 6. This will reset the scanner to its
factory settings.

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 WCS 3900 Series Scanners are extremely rugged
since theyhaveno moving parts. WCS 3900 Series Scanners support PC
AT/XT and PS/2 keyboard interfaces and easily wedge 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. 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. The scanner can read bar codes with
X-dimensions as low as 5 mils (0.005 in/0.13mm).
WCS 3900 Series 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.

1. Plug the USB of the WCR 3900 / 3905 Scanner directly into your PC’s
USB port.
1. Turnoff your computer.
2. Unplug your PC keyboard cable and plug the male end (Din 6) of the WCS
3900 / 3905 Scanner directly into your PC keyboard port. Plug your
keyboard cable into the other end (female Din 6) of the the scanner.
3. Turn your computer on.

Your Wasp WCS 3900 / 3905 Scanners are ready for use. The default settings of
the scanners have been pre-programmed for the most common bar code
configurations. Use the “WCS 3900 / 3905 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.

In order to configure Wasp WCS 3900 / 3905 Scanners, you must familiarize
yourself with the setup procedures on the following pages. The default settings
of the scanners are identified on each page and clearly marked using an
asterisk (*). The default settings have been programmed for the most
common bar code configurations. Use the setup & configuration barcodes
only to customize the WCS 3900 / 3905 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 the WCS
3900 / 3905 Scanners are removed by turning off your PC.
In order to configure Wasp WCS 3900 / 3905 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 twobeeps.
To change Minimum/Maximum Length:
(1) Scan the Minimum or Maximum Length bar code on page 15.
(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. 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
WCS 3900 / 3905 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 strayor scrambled characters appear, increase the intercharacter delay
to slow down the transfer rate.
