General Information
CCD (charged coupled device) scanners are,
depending on model type, either contact or near
contact scanners. Because CCDs scan
automatically when approaching or pointing at a
bar code label, their operation is intuitive. CCDs
read difficult labels found on curved or irregular
surfaces and perform especially well in high
ambient light conditions. They are a cost-
effective, inexpensive alternatives to other
scanning technologies.
Featuring state-of-the-art imaging technology,
CCDs use the same sensor found in facsimile
machines or video camcorders. The CCD images
the bar code label, then converts the digital signals
into data the host computer can understand. By
capturing the bar code image all at once, the
scanner provides a fast, highly accurate read rate.
Miniature surface mount electronics make up the
CCD scanners solid state construction. CCDs have
no moving mechanical parts and provide years of
trouble-free operation.

Wedge Interface
The HLT/ELT series Wedges have built-in
intelligence to connect directly to a personal
computer without the need for a separate decoder
box. Scanned bar code labels appear to the
computer as if the data was typed into the
keyboard. Normal operation of the keyboard is
unaffected. The WEDGE interface is compatible
with virtually any application program accepting
keyboard input.
Advantages
•Low cost  no separate decoder box required
•No special software installation or technical
support needed
•Same communication signal format as
keyboard
•Simple installation
•No external power supply
•Full featured bar code menu offers user
flexibility
•Uses existing keyboard type

Set Up
Unpacking
Remove the scanner from its packaging and
inspect it for damage. If the scanner was
damaged in transit, call the Opticon Customer
Service Dept. at 800-636-0090.
Installation
A Y connection cable is provided for installation.
The scanner is installed or wedged between the
keyboard and the computers CPU.
The Y cable connects both
the scanner and the keyboard
to the computer.
WARNING!
In order to avoid possibility of
damage to the computer, install the
CCD scanner and Y cable when
power to the system is OFF.

Programming the Scanner
This manual provides an easy way of changing
certain parameters. A parameter is changed by
reading a specific bar code associated to a specific
function.
To select menu options:
1. Scan Start/End Program Menu. The
scanner will beep continuously to indicate that
it is ready to be programmed.
2. Make parameter selection from menu (a beep
and a green light indicates that the parameter
has been scanned).
3. Scan  Start/End Program Menu. This
completes the operation and the new
parameter is saved in memory.
The CCD reader is normally programmed as a
keyboard wedge for IBMs XT, AT, or PS/2 Models
50, 60, 70 and 80. If the host computer is not one
of these models, refer to Computer Type
Selection on page 18 to make another selection.
NOTE: (B) A pointing finger indicates scanner
default settings.

Scanning
If the scanner has a switch, depress button on
underside to turn the scanner on. Red LED
illumination will emit from the scan window. If the
scanner does not have a trigger switch, then the
LEDs will automatically remain on as long as the
computer system is on.
NOTE: The scanner will not read any bar code
label which is wider than the scan window.
1. Approach, point or touch the bar code label
with the scan window of the CCD scanner.
2. Scan within a distance of 0 to 1.0" (2.3"
window); 0 to 2.5" (3.2" window) from the bar
code label.
3. Center the CCD scan window on bar code label
for fastest read.
4. The scanner will beep to indicate an audible
good read * (if beeper has not been turned off
by a menu option).
5. A green LED indicator will visually signal a
good read.
* The scanner reads all bar code symbologies
listed in the menu section of this manual.

User Maintenance
Cleaning the scan window is the only maintenance
that is required.
♦Do not allow any abrasive material to touch
the window.
♦Remove any dirt particles with a damp cloth.
♦Clean the scan window using a soft cloth or a
cotton tipped swab moistened with water.
♦Do not remove the nose of the scanner.

Troubleshooting
A. If LEDs do not light up when installation
instructions are followed:
•Make sure there is power to the system.
•Recycle computer power.
•Verify computer fuses are ok.
•Check for loose cable connections.
•Are adaptors being used?
B. If LEDs light up, but good read beep is
not heard and no data appears on the
computer:
•Make sure the distance between the scanner
and bar code label is not greater than the
specified depth-of-field when trying to read it.
•Verify the bar code label is readable and meets
bar code specification.
•Check to see if the scanner reads other bar
code labels (if yes, the non-reading label may
be a label which the scanner is not
programmed to decode.)
•Verify that the bar code label is not wider than
the CCD scan window.

C. If LEDs light up, good read beep is heard
but no data appears on the computer:
•Check to see that the Computer Type
Selection matches the type of computer that
you are using.
•Change the Intercharacter Delay setting.
Depending upon the type of computer that
you are using, the intercharacter delay will
vary.
•If you are using a file sever, an interrupt
conflict may arise. Opticon recommends using
an RS232C CCD scanner interface on file
servers.
NOTE: If after performing these checks, the
scanner is still not functioning, contact your
distributor or call Opticon Technical Support at
800-636-0090.
Factory Service
When calling Opticon Technical Support, please
have the unit model number and several bar code
labels readily at hand. The model number is
located near the connector end of the cable.

Glossary
ASCII - American Standard Code for Information
Interchange. A 7 bit plus parity code representing
128 letters, numerals, punctuation marks, and
control characters. It is a standard data transmis-
sion code in the US.
Autodiscrimination - The ability of bar code
reading equipment to recognize and correctly
decode more than one symbology.
Bar Code - An automatic identification technology
which encodes information into an array of varying
width parallel rectangle bars and spaces.
Bar Code Density - The number of data charac-
ters which can be represented in a linear unit of
measure. Bar code density is often expressed in
characters per inch.
CCD (Charged Coupled Device) - A technology
in which scanning is accomplished with an array of
LEDs flooding the bar code with light.
Check Digit - A digit used to verify a correct
symbol code. The scanner inserts the decoded
data into an arithmetic formula and checks that
the resulting number matches the encoded check
digit. Check digits are required for UPC but are
optional for other symbologies. Using check digits
decreases the chance of substitution errors when a
symbol is decoded.
Codabar - A discrete self-checking code with a
character set consisting of digits 0 to 9 and six
additional characters (- $ : / , +).
Code 128 - A high density symbology which
allows the controller to encode all ASCII characters
without adding extra symbol elements.

Glossary (cont.)
Code 3 of 9 (Code 39) - A versatile and widely
used alphanumeric bar code symbology with a set
of 43 characters types, including all upper case
letters, numerals from 0 to 9 , and 7 special
characters (- / . + % $ and space). The code
name is derived from the fact that 3 of 9 elements
representing a character are wide, while the
remaining 6 are narrow.
Decode - To recognize a bar code symbology and
then analyze the content of the specific bar code
scanned.
Default - A standard setting assigned to a
parameter type unless a different setting is
assigned to that parameter.
Depth of field - The distance between the
maximum and minimum plane in which bar code
reader is capable of reading symbols.
EAN (European Article Number) - This
European/International version of the UPC pro-
vides its own coding format and symbology
standards. Element dimensions are specified
metrically. EAN is used primarily in retail.
Encode - To translate data into machine readable
form using the format and conventions of a
specific bar code symbology.
Host Computer - A computer that serves other
terminals in a network, providing such services as
computation, database access, supervisory pro-
grams, and network control.

Page 15
Glossary (cont.)
Interleaved 2 of 5 - A binary code symbology
representing character pairs in groups of five bars
and five interleaved spaces. Interleaving provides
for greater information density. The location of
wide elements (bars/spaces) within each group
determines which characters are encoded. This
continuous code type uses no Inter-character
spaces. Only numeric (0 to 9) and START/STOP
characters may be encoded.
Parameter - A setting that can have a different
function assigned to it.
Programming mode - The state in which a
scanner is configured for parameter settings.
Quiet Zone - A clear space, containing no
machine readable marks, which precedes the start
character of a bar code symbol and follows the
stop characters.
Read Rate - The ratio of the number of successful
reads on the first attempt to scan to the total
number of attempts.
Resolution - In a bar code system, the narrowest
element dimension which can be distinguished by
a particular reading device or printed with a
particular device or method.
Scanner - An electronic device used to scan bar
code symbols and produce a digitized pattern that
corresponds to the bars and spaces of the symbol.
Scanning Mode - The scanner is energized,
programmed, and ready to read a bar code.

Page 16
Glossary (cont.)
Start/Stop Character - A pattern of bars and
spaces that provides the scanner with start and
stop reading instructions and scanning direction.
The start and stop characters are normally to the
left and right margins of a horizontal code.
Symbology - The structural rules and conventions
for representing data within a particular bar code
type.
UPC (Universal Product Code) - A relatively
complex numeric symbology. Each character
consists of two bar codes and two spaces, each of
which can be any of four widths. The standard
symbology for retail food packages in the United
States.
Wedge - A device that plugs in between a
keyboard and a PC. Includes a scanner allowing
data to be entered either by a keyboard or scan-
ner.
