Wasp Bar Code Scanner WLP 4170 CCD User 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.

Chapter 1  
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.

Quick Start  
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.

Chapter 4  
Bar Code Symbologies  
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.

Setup & Configuration  
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 “Set” 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.

Setup & Configuration  
—Factory Default  
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.  
1. Scan “Begin ”

2. Scan “Default” to restore  
scanner to default settings

NOTE: Scanning these bar codes returns the scanner to  
the factory default settings

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.

Setup & Configuration  
—Intercharacter Delay  
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.

name of the symbol is derived from the format of the code. PDF stands for "Portable Data  
File" and "417" is derived from the module structure. Each PDF417 symbol consists of 3 to  
90 stacked rows surrounded by a quiet zone on all four sides. Each row consists of a leading  
quiet zone, start pattern, left row indicator character, one to thirty data characters, right row  
indicator character, stop pattern, and trailing quiet zone.  
PDF417 supports text compaction, numeric compaction, and byte compaction that correlate  
the mapping between code word values and decoded data. PDF417 can accommodate up  
to 340 characters per square inch with a maximum data capacity of 1850 text characters.
