Wasp WLP 4170 Programming Manual

Wasp WLP 4170 CCD
Programming Guide

Please Read

Note:

The Wasp WLP 4170 CCD Scanner is ready to scan the most
popular bar codes out of the box. This manual should only be

used to make changes in the configuration of the scanner for
specific applications. This scanner does 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.

Tech Tip

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 black mark and a
white space. Wasp WLP 4170 CCD is extremely rugged since it has no moving
parts. Wasp WLP 4170 CCD reader supports PC AT/XT and PS/2 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 by hand by a
data entry operator.

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.

1. Turn off your computer.

2. Unplug your PC keyboard cable and plug the male end (Din 5) of the Wasp
WLP 4170 CCD Scanner directly into your PC keyboard port. Plug your
keyboard cable into the other end (female Din 5) of the the Wasp WLP 4170
CCD Scanner. If your keyboard and PC support a Din 6 connection, use the
enclosed Din 5 to Din 6 converter cable to connect to the keyboard power
tap cable.

3. Turn your computer on.

Your Wasp WLP 4170 CCD Scanner is ready to go. The default settings of the
Wasp WLP 4170 CCD Scanner have been pre-programmed for the most common
bar code configurations. Use the "Setup & Configuration" sections only to
customize the Wasp settings.

Tip: Use the pre-printed "Bar Code Test Symbols" in Appendix A on page 30 as a
test chart to begin practicing scanning.

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 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 WLP 4170 CCD Scanner can read bar codes with X-dimensions as
low as 4 mils (0.10mm).

Wasp WLP 4170 CCD Scanner can read the most popular linear 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, and also the 2D bar
code symbology PDF417.

Please see test chart on pages 30-33.

In order to configure Wasp WLP 4170 CCD Scanner, you must familiarize yourself
with the setup procedures on the following pages. The default settings of Wasp
WLP 4170 CCD Scanner 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 settings. If you need to configure Wasp WLP 4170 CCD

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 keyboard power to Wasp WLP 4170 CCD Scanner is removed
by turning off your PC.

In order to configure Wasp WLP 4170 CCD Scanner, seven basic steps need to be
followed for each programmed setting:

(1) Determine what, if any, options on EACH PAGE that you wish to change.
(2) Scan the "Begin" bar code. WLP 4170 CCD Scanner will sound an ascending

tone to indicate that setup is in progress.
(3) Scan the bar code representing the option to be changed.
(4) Scan the bar codes representing the option values (e.g. 01, 02, 3A etc.).

These option values can be found on the inside back cover flap of this manual.

You must scan two digits for each option setting.
(5) Repeat the above two steps, if necessary, to change the options in the

same group.
(6) Scan the “Finish” bar code on the back cover flap to confirm your selections.
(7) Scan the "Exit" bar code to exit the group currently selected.

Wasp WLP 4170 CCD Scanner will sound a descending tone.

NOTE: Pages 6 and 7 are designed as walk through example pages. Use these
pages as examples on how to change an option for the rest of the manual.

NOTE: Scanning these bar codes returns the scanner to the

factory default settings

1. Scan “Begin ”

2. Scan “Default” to restore

scanner to default settings

Tip: Use this configuration to restore the factory default settings if you are unsure
how your scanner has been configured. The 'Factory Default' configuration is very
useful when you need to reprogram your Wasp
WLP 4170 CCD Scanner after the defaults have been changed. By setting
the default configuration, the user knows precisely the configuration for each
programmed setting.

The 'Beep Volume' configuration changes the volume of the audible indicator of
the WLP 4170 CCD Scanner.

NOTE: For help in configuring these settings, consult the programming steps on
page 5.

1. Scan “Begin ”

2. Scan “Set Beep Volume”

4. Scan the “Finish” barcode on

the back cover flap

5. Scan the “Exit” barcode

3. Pick a setting from the table at
right, then turn to the back cover
flap and scan the corresponding
two digits. For example: if you
desire no beep, scan 0 and 0 on
the back cover flap

Intercharacter Delay Settings

00 Slowest
01 Slow
02 Default
50 Medium
75 Fast
99 Fastest

The 'Intercharacter Delay' configuration sets the speed at which the WLP 4170
CCD Scanner sends data. The intercharacter delay should be changed only if the
transfer rate cannot be maintained between WLP 4170 CCD Scanner and the
keyboard buffer of the computer.

Note: The default for the intercharacter delay is set to '2ms' and is the most
common configuration; however, your PC may be different. When you scan a bar
code, if some characters are missing, decrease the intercharacter delay speed to
speed up the transfer rate. If some stray or scrambled characters appear on your
screen, increase the intercharacter delay to slow down the transfer rate.

Note: For help in configuring these settings, consult the programming steps on
page 5.
