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.
