Getting Started

General Information

The LGZ 7225 CCD Scanner utilizes state-of-the art imaging technology similar to that found in digital
cameras, fax machines and video camcorders. The captures an “image” of the bar code and converts it into
digital signals that the host computer understands.

The scanner automatically recognizes most common bar code symbologies.

The scanner, which utilizes miniature, surface-mounted electronics, has no moving parts and will provide
years of trouble-free operation.

The LGZ 7225 is available in several different interface configurations.

 Keyboard Wedge (PS2 or AT/XT)
 RS 232
 USB

Unpacking

Remove the scanner from its packaging and inspect it for damage. Save the carton and packing material. If
the scanner was damaged in transit, call the dealer or distributor from whom you purchased it. If you
purchased it directly from Opticon, call Opticon Customer Service Dept. at 800-636-0090.

Opticon Customer Service and Support

If you have any questions or need assistance with installing or programming your scanner call Opticon
Customer Service Department at [phone].

Before you call, record the model number of the scanner. This information is located on the bottom side of
the scanner. Also please have the scanner available plus some bar codes to scan.

Programming the
LGZ7225

To program the LGZ7225 you must scan a series of

programming barcode in the correct order. Fold out the back

cover of this manual. You will see a table of alphanumeric

barcodes, which are used to program the various options

presented.

To program each option, you must:

1. Scan the Program barcode on the parameter setting part.

2. Enter the option mode by scanning the Option Bar Code

(also on the Parameter setting part).

3. To the right of the option barcode, the necessary

alphanumeric inputs are listed. Scan these alphanumeric

entries from the back fold out page. To confirm above

steps, you must scan the Finish barcode on the back fold

out page.

4. Once you have finished programming. Scan the Exit

barcode, listed on the lower right hand corner of each

parameter setting part.

Interface Selection

This decoder built-in scanner comes in one model and
supports interfaces such as keyboard wedge, RS232 serial
wedge, wand emulation, and the latest USB interface. In
most of the cases, simply sutilizing the an appropriate cable with
a device code will work for a specific interface.
Interface selection: You can change factory interface
default for other type interface. By plugging different cables,
setting correct interface, then the scanner will be changed to
another interface. However, you must make sure which cable
you need.
Keyboard/RS232/UBS Auto detection: By setting this
function, it will automatically select the Keyboard wedge or
RS-232 or UBS interface for user.

Keyboard wedge

As a keyboard interface, the scanner supports most of the
popular PCs and IBM terminals. The installation of the wedge
is a fairly simple process without any changes of software or
hardware.

Keyboard Type: Select keyboard type connector of your
host computer. Scanner must be selected to the appropriate
host interface cable converter.

Keyboard Layout: The selecting of keyboard layout

supports many country languages other than USA keyboard
layout. First you need to confirm country language that you
desire. In DOS, using command “keyb” to select the
desirable keyboard layout or in WINDOWS entry “Control”
then pops “Keyboard” to select country at “language” item.
For details, please refer to your DOS or WINDOWS user’s
manual.
Keyboard Speed: By selecting, you can change output
speed of scanner to match with host computer. Generally, set
00 or 01 in working high speed. If some output characters of
barcode have been lost, you may need to set 05 or 06 to
match your host keyboard speed.
Function Key: Set Enable , scanner can output code as
pressing function-key in your application program while the
barcode datas contain ASCII value between 0116 to 1F16.
Refer to ASCII table, page 94.
Numeric Key: The Keypad has to be selected if your
application program is only keypad numeric code acceptable.
So, scanner will output code as press numeric keypad when
it read numeric digit. (The keypad is in the right side of
keyboard, and Num Lock control key is also on.) If
Alt+Keypad is selected, Caps Lock and output will be
independent.

Caps Lock: By selecting Caps Lock or No Caps Lock,

scanner can get Caps Lock status.

Power-on simulation: All of the PCs check the keyboard
status during power-on selftest. It is recommended to Enable
function if you are working without keyboard installation. It
simulates keyboard timing and pass keyboard present status
to the PC during power-on.

Inter-character delay: This delay is inserted after each data
characters transmitted. If the transmission speed is too high,
the system may not be able to receive all characters. Adjust it
and try out suited delay to make system work properly.

Block transmission delay: It is a delay timer between
barcode data output. The feature is used to transfer
continually with shorter barcode data or multi-field scanning.

Xon: Transmit On (ASCII Code 11

Flow control:
None-The communication only uses TxD and RxD signals

without regard for any hardware or software handshaking
protocol.
RTS/CTS-If the scanner wants to send the barcode data to
host computer, it will issue the RTS signal first, wait for the
CTS signal from the host computer, and then perform the
normal data communication. If there is no replied CTS signal
from the host computer after the timeout (Response Delay)
duration, the scanner will issue a 5 warning beeps.
Xon/Xoff- When the host computer is unable to accept data,
it sends a Xoff code to inform the scanner to suspend data
transmission, and Xon to continue.
ACK/NAK- When the ACK/NAK protocol is used, the
scanner waits for an ACK (acknowledge) or (not
acknowledge) from the host computer after data transmission,
and will resend in response to a NAK.

Inter-character delay: It is delay time between data
character’s data output. It is also same as Inter-char. delay of
keyboard wedge.

Block transmission delay: It is a delay time between

Scan

Scanning mode:
Good-read off-The trigger button must be pressed to

activate scanning. The light source of scanner stops
scanning when there is a successful reading or no code is
decoded after the Stand-by duration elapsed.
Momentary-The trigger button acts as a switch. Press button
to activate scanning and release button to stop scanning.
Alternate-The trigger button acts as a toggle switch. Press
button to activate or stop scanning.
Timeout off-The trigger button must be pressed to activate
scanning, and scanner stops scanning when no code is
decoded after the Stand-by duration elapsed.
Continue-The scanner always keeps reading, and it does
not matter when trigger button is pressed or duration is
elapsed.

Same Barcode delay time: If the barcode has been
scanned twice, then only the first barcode will be accepted.

Double confirm: If it is enabled, the scanner will require a
several times successful decoding to confirm the barcode
data. The more confirming times required the more inhibitive
miss-reading code will be shown. If you set Double confirm,
the Multi field scan Enable function won’t be able to work.

Scan

Multi field scan: The scanner can be read many sets of

barcode data on the same scanning line at the same time,
even if they are different kinds of barcode symbology.
Global min./max. code length: Global Minimum and
Maximum length can be set to qualify data entry. The length
is defined as the actual barcode data length to be sent. Label
with length exceeds these limits will be rejected. Make sure
that the Minimum length setting is no greater than the
Maximum length setting, or otherwise the labels of the
symbology will not be readable. In particular, you can set the
same value for both Minimum and Maximum reading length
to force the fixed length barcode decoded. The values of
setting have no effect on certain symbologies with fixed
length.
Notes 1): Please set the min/max length if you have special

demand for individual barcode.

2): Include the Check sum digits if you want to set
Global min/max code length.

Inverted image scan:. Set Enabled the scanner will scan
both black/white barcode with white/black background.
CTS trigger: This operation enabled an external device to
control scanning. The CTS trigger is controlled by apply an
external trigger signal to the CTS input. When active, this
signal causes scanning to begin as the scanner’s trigger was
depressed.
Position indication: This function can indicate the specific
location before scanning. You can also set up the time of
indication(except AS-8110).
