Introduction and Getting Started
Product Overview
The LPN5627 and LPR5627 (Raster) Fixed Position Scanners are miniature, 500 scan per second, laser
bar code readers designed to be easily incorporated into host equipment. The high scan speed and small
physical size make the scanner easy to integrate into any hardware design. Durability and reliability are
assured.
Advanced microprocessor technology coupled with Opticon’s proven decoding algorithms result in high
speed operation with superior accuracy. The scanners are fully programmable allowing the user to
customize parameters including changing communication settings, selecting symbologies, adding prefixes
and appending suffixes. Programmable settings can be downloaded from the host CPU or computer
directly to the scanner.
The scanners are encased in compact, rugged metal enclosures. The compact size permits installation in
the tightest areas allowing great flexibility in mounting and positioning the scanner for optimum
performance.

LPN5627 / LPR5627 Laser Fixed Mount
Section 3
Positioning the Scanner
Achieving Optimum Performance
Three items greatly impact performance:
1) Distance (from the scan window) to the bar code
2) Specular Reflection
3) Quality of Bar Code Labels
1) Distance to the Bar Code
The operation of the scanner is similar to a camera. If you photograph an object that is out of focus, the
resulting picture will be blurry. The same is true with the scanner. If the bar code label is out of focus,
the scanner may have difficulty decoding what appears to be fuzzy bars and spaces.
Focal Distance
Ideally, the distance from the window of the scanner to the bar code label should be equal to the focal
distance of the scanner. For the LPN5627 / LPR5627 fixed position scanners, the nominal focal distance
is approximately 4.0” from the front edge of the scanner
Depth-of-Field
Just as with a camera, the scanner has a depth-of-field. It can read bar codes that are not precisely at
the focal distance - maybe a little closer, or a little farther away. However, if the bar code label is
positioned too far from the focal distance, the scanner may not be able to successfully decode it.
The depth-of-field varies based on the density of the bar code, i.e., the thickness of the bars. Very high
density bar codes (which have very narrow bars) are readable over a much shorter distance range than
low density bar codes with larger bars.
The following table shows the depth-of-field specifications (closest to farthest reading distances) for the
LPN5627 / LPR5627 scanners. The actual performance may differ slightly from unit to unit. Also, it is
important to note that this data was measured under ideal conditions using high quality bar code labels.
In a “real world” environment the conditions will not be as ideal. Therefore, the best practice is to
position the scanner at the center of the depth-of-field rather than at the extremes of its depth-of-field.

The table above shows the field-of-view at various distances from the window. The field-of-view is the
maximum width that the scanner is capable of reading. It is the distance from the left edge of the view
to the right edge. A bar code label positioned anywhere within this field-of-view can be decoded. The
field-of-view is also a measure of the widest bar code label that can be read. Remember: The width of
a bar code label includes not only the bars and spaces but also the required white space (quiet zone) on
each end.
Good design policy is to position the barcode at the midpoint of the scanner’s depth-of-field and at the
center of the field-of-view. Do not position it near the extremes of the reading range.
Comparable depth-of-field parameters for the LPR5627 are the following:

2) Avoiding Specular Reflection
Do not position the scanner at an angle that causes the laser light to be reflected directly back into the
scanner. This is called specular reflection. Too much reflected light can “blind” the scanner preventing a
good decode.
If the bar code label is located on a flat surface, specular reflectivity occurs between 0 to 10 degrees off
perpendicular. (See diagram) If the bar code label is located on a cylindrical surface, such as a test
tube, the angle of specular reflection is measured tangent to the curve. If the curved surface is also
moving, there may be more than one position causing specular reflection. The following diagram
indicates the area to avoid:

3) Quality Bar Code Labels
The quality of the bar code label can affect the scanning performance. Poor quality labels are more
difficult to decode and may result in non-reads or potential misreads. The bar code label should be
printed to specifications. This means that the bars are printed within spec, with the correct widths, no
ink spread, crisps edges and no voids. There should be a sufficient quiet zone on both end of the bar
code label. For best results, the paper or label stock should have a matte finish to diffuse light. The
print contrast signal (which is a comparison of the reflectance of the bars and the background stock)
should be as high as practical.
Measuring Scanner Performance
Two methods are helpful in determining the optimum position of the scanner. The first method is to
program the scanner for Trigger Disable and Continuous Read modes. The scanner will be always on
and will continuously read the same bar code. Since the buzzer sounds each time the bar code is read,
the sound of the buzzer can be used like a “Geiger counter”. As the position of the scanner changes the
sound of the buzzer will change. The buzzer sound will be loudest and most continuous at the best
reading positions.
The Read Rate Test
The second method, the Read Rate Test, provides a mathematical calculation of scanning performance.
In this test the scanner scans a bar code 700 times and then calculates the number of those scans that
resulted in a good decode. That number, expressed as a percentage, will be transmitted to the host.
For example, 93% means that the scanner decoded the bar code symbol 93 times out of the 650 scan
attempts. By performing the Read Rate Test with the scanner mounted in various positions you can
determine which of those locations results in the best performance.
How to perform the Read Rate Test
Perform the following steps after you have correctly configured communications to the computer via your
RS232C port and power is made available to the scanner:
Send the command: <Escape> U8 <Carriage Return> Note: Be sure to use capital letters, e.g.
“U8”, not “u8”.

The scanner will read the barcode continuously and will display the ratio of the number of successful
reads to the total number of attempts.
The printout on the screen will appear as follows:
(Example)
700d OK 93.5%
CODE-39 TEST
The number in the upper left indicates the number of times the decoder ran while scanning at 700 scans
per second. The number can be lower than 700 when reading noisy barcodes. The upper right
percentage indicates the ratio of the number of successful reads to the total number of attempts. By
positioning the scanner at the optimal distance from the barcode with the correct orientation and with a
grade-A quality barcode readings of 95% or higher are expected. Reset the scanner after testing.

Application Notes
Tips for Achieving High Throughput
In some applications your primary objective may be to achieve the highest possible throughput rate. The
following list identifies the parameters and scanner settings that can maximize scanning and decode
throughput speed. Note, by emphasizing maximum throughput, other areas of performance may be
affected. For example, the number of non-reads could increase.
If high throughput is critical, consider some or all of these settings:
♦
Operate in the Trigger Disabled mode. Operation of the trigger can require as much as 200
msec before decoding begins, slowing down throughput rate.
♦
♦
♦
♦
♦
Only enable those symbologies that you will be decoding.
Eliminate all suffixes and prefixes.
Minimize the number of redundant reads required before transmitting data.
Transmit the decoded data at the highest baud rate, 38,400 baud.
Disable buzzer functions.
Tips for Insuring Highest Data Integrity
There are several parameters that can enhance your confidence that the correct bar code data is
transmitted. Note that by emphasizing the accuracy and security of the data other areas of the scanner
operation may be affected, for example, you may not achieve the highest throughput.
If accuracy and data integrity are critical, consider some or all of these settings:
♦
Program the scanner to require a high number of redundant decodes prior to transmitting. For
example, program the scanner to decode a bar code exactly the same way three consecutive times
before transmitting the data. Then decoding the bar code the same way 2 out of 3 times or any 3
out of 4 times is not sufficient. It must obtain three consecutive and identical decodes.
♦
Utilize a predetermined, fixed-length of bar code. Program the scanner to only decode a bar code of
that length. Bar codes of any other length will be ignored.
♦
♦
The quality of the printed bar code must be excellent.
Use a bar code symbology that contains an internal check digit and program the scanner to calculate
that check digit for validity prior to transmitting.
♦
Do not use a symbology with poor internal verification, or subject to partial decodes, such as 2 of 5
or MSI/Plessey.
♦
♦
Only enable those symbologies that you will be decoding.
Transmit data at low baud rates to minimize communication errors.
Enable the “Number of Characters Transmitted”. The scanner will calculate and transmit a number
indicating the total number of characters it is transmitting. Your host application program can compare
this number with the actual number of characters received to verify that the correct amount of data is
received.

Tips for Verifying the Presence of a Bar Code
If the scanner is operated in the “trigger enabled” mode and the trigger is activated, one of three
conditions may occur:
A bar code is scanned and decoded.
Decoded data is
transmitted
A bar code is scanned but is not decoded
(e.g., print quality was poor)
No bar code is present
No data is transmitted
No data is transmitted
In some applications, when no data is transmitted, it may be important to know why. Was there a bar
code present that could not be decoded, or was no bar code present at all?
This requirement is common in applications such as automated blood analysis equipment. Test tubes
containing blood samples from many different people are loaded into a rack for automatic analysis. The
bar code on each tube ties that sample and the results back to a specific individual. If no bar code data
is transmitted it is critical to understand the reason.
Your Opticon scanner, when operated in the Trigger Enabled mode, can be programmed to transmit an
error message indicating whether or not a bar code was present. The following table shows the message
that will be transmitted for each condition.
Presence/Absence of bar code
Bar code was present and correctly decoded
No bar code was present

Configuring the Scanner
Since the operation of the LPN5627 / LPR5627 scanners are microprocessor controlled, it is possible to
modify or program its operation to match your specific application. Changes in parameter settings can
be accomplished two ways.
1. The scanner can be programmed by sending software instructions from the host PC to the scanner
via the RS232 connection.
2. The second method employs specially designed programming bar codes. Scanning these bar codes
instructs the scanner to modify specific parameters.
Programming Menus & Commands
Appendix A contains full instructions on how to configure the scanner as well as a complete listing of the
computer commands and programming bar codes that are available to customize the scanner for your
application.
Default Settings
When you modify or change any parameters, the scanner can be programmed to retain the new
parameter in memory, even if power interrupted or terminated. If for any reason the scanner is
instructed to return all parameters to default settings (U1), it will return to the default settings shown in
the following table.
Default settings are indicated by a pointing hand symbol (
) throughout the bar codes menus.

0090.
Common Causes of Poor Performance
The most common reasons for poor scanning performance are listed below:
♦
♦
Bar codes are not positioned at the focal distance of the scanner.
Specular reflection is impacting the scanner. Change the angle/position of the scanner or the bar
code.
♦
♦
Poor quality of printed bar codes. Bar codes are out of specification.
The paper on which the bar code is printed is highly reflective or has a glossy finish causing light to
be reflected into the scanner.
♦
The distance from the scanner to the bar code is not suitable for the density of the bar code. Or the
density of the bar code beyond the scanners capability. If the red illuminating light of the scanner is
not on, the scanner may be in the “Trigger Enable” mode expecting a trigger signal.
Modified and/or Customized Scanners
Opticon will work with you to modify or customize scanners to match your requirements. Scanners can
be modified in terms of connectors type, pin-outs, cable length, default settings, custom software and
many other areas.
Opticon will modify scanners in our factory and ship you scanners that match your specific requirements.
By incorporating your modifications directly into production scanners, you receive scanners tailored for
your need. They can be used immediately without the need for further modification or rework.

LPN5627 / LPR5627 scanners comply with Center for Devices and Radiological Health (CDRH) regulations
21, CFR Subchapter J. It is classified as a Class II Laser Device
The LPN5627 / LPR5627 scanners use a low-power visible laser. As with any very bright light source,
such as the sun, you should avoid staring into the light beam. Momentary exposure to a CDRH Class II
laser is not known to be harmful.
A laser safety label, manufacturers label and product label are affixed to the scanner as shown
If the LPN5627 or LPR5627 scanner is incorporated into or interfaced to other equipment, that equipment
should include a laser safety label and a visible indicator that is illuminated whenever laser energy is
being emitted from the scanner. This indicator may remain illuminated when the scanner is powered but
the laser is not emitting energy
Section 7 Scanner Servicing and Maintenance
CAUTION: Use of controls or adjustments or performance of procedures other than those
specified herein may result in hazardous laser light exposure.
The LPN5627 / LPR5627 scanners contain no user adjustable or serviceable parts in the interior of the
scanner. All product service must be performed by the Opticon Service Department in Orangeburg, NY.
Opening the scanner will void the warranty and could expose the operator to laser light.
The LPN5627 / LPR5627 are warranted for 1 year including parts and workmanship. If you need
warranty or out-of-warranty repair, first call 1-800-636-0090 to obtain a Returned Material
Authorization (RMA) number. You will be provided a number and shipping instructions.
There is no scheduled maintenance required for the LPN5627 / LPR5627. The scanner can be cleaned
using a water dampened, lint free or lens cloth. Be careful to avoid excessive moisture that would
penetrate the housing or obscure the window. While use of cleaning fluids other than water are not
recommended, a neutral detergent or ethanol would be preferred if necessary. Do not use bleach at full
or diluted strength as damage to the painted case and/or window may result.

Appendix A
Programming the Scanner
Two different methods can be used to program parameters to configure the scanner:
a. Programming via Computer Commands
b. Programming via special Bar Codes from a menu page
Most parameters can be programmed using either of these two methods. However, there are certain
parameters that are only programmable via the bar code menu.
a. Programming via Computer Commands
Parameters can be programmed by sending software commands or keyboard strokes from the host
computer to the scanner in the following format:
<ESC> Computer Command <CR>
Note:
Only upper case letters are recognized, e.g., “AB” not” ab”
Each command normally consists of two characters
Downloading of software commands cannot be “grouped” together. Each command
must be preceded by <ESC> and followed by a <CR>
Parameters programmed by downloaded commands can be stored permanently by transmitting a
“<ESC> Z2 <CR>” command. It is not necessary to send a “Z2” command after each parameter is
changed. One Z2 command will save all changes
Appendix B lists all of the Computer Commands. In Appendix C, Bar Code Programming Menus, the left-
hand column in all menus contains the Computer Command associated with that bar code.
b. Programming via Bar Codes
Use the following steps to program parameters via the bar code menus:
1. Scan the “Start/End” bar code. This instructs the scanner to enter the Programming Mode.
While in this mode the scanner will beep intermittently.
2. Scan the bar code(s) associated with the desired parameter(s). The scanner will beep when the
bar code is read. Note: because of the close proximity of bar codes on the page, it iis important
to aim carefully to ensure that only the desired bar code is scanned.
3. Scan the “Start/End” bar code. This instructs the scanner to exit the Programming Mode.
All the parameters that were scanned are retained in memory and are stored permanently (even if the
scanners is power down) or until they are changed again.
When the scanner is in the Programming Mode, you can change more than one parameter at a time.
However, this may become confusing. Until you be come proficient at programming you may prefer to

change only a few parameters at one time. We recommend that you keep a record of the changes you
have made to the scanner.
What if you make a mistake?
Don’t worry. If you are programming the scanner but are unsure of which parameters have been
changed, scan the Reset All Defaults bar code. This bar code returns the scanner to the default
settings that were installed in the factory at the time the product was manufactured. Scanning this bar
code erases any change you have made, including any changes that were made during previous
programming.
Reset All Defaults U1 Command (U1)
This command will return all setting to the factory default setting that were installed in the factory
We recommend that after you have reset all defaults you also set the commands for No Handshaking
(P0), All Symbologies (A0), and Do Not Transmit Start/Stop Characters (D0) for Code 39.

Scanner Test Mode (U0) - This mode resets all unit parameters to a predefined set of defaults for the
purpose of putting the scanner into a test mode which reads barcodes continuously. The predefined
defaults are the following:
♦ Reads all barcodes by symbology
♦ No fixed number of digits defined (32 digits minimum).
♦ Normal scan, continuous scan.
♦ Large only.
♦ No verification, no "Bad Read (BR)".
♦ Buzzer 3KHz, volume maximum.
♦ Buzzer after decoding (10 ms).
♦ Good LED after decoding (green, 100 ms).
♦ RS232C (9600 baud, 8, 1, no parity, no handshaking).
Straight Across Scan Mode (U3) - This mode resets all unit parameters to predefined defaults for the
purpose of allowing straight across scanning of up to 3 labels. The predefined defaults are the following:
♦ Reads all barcodes by symbology.
♦ No fixed number of digits defined (32 digits max.)
♦ Normal scan, multiple scan.
♦ Trigger disable.
♦ Small and large.

If a check digit is present, it will appear as part of the data.
If the scanner is programmed to calculate the check digit, and the bar code is not printed with a
check digit, the bar code will not read.
Another option available for Code 39 is to enable the reading of a single character bar code. See the
section on Fixing the Digit for this option.

Codabar (NW-7) has four different start/stop character schemes as shown above. The check digit is
optional and, if present, would be the last character.
If the scanner is programmed to calculate the check digit and the bar code is not printed with a

The IATA code is a variable length symbology with an optional check digit and non-printable start/stop
characters. The following characters are supported: Digits 0 up to 9.
The checksum is calculated as the modulo seven of the data string. IATA is an acronym for International

To avoid truncation errors, the scanner can be programmed to only decode bar codes of one specific
length, i.e., containing a specific number of digits. It is also possible to program the scanner to only
decode bar codes of either of two specific lengths.
To fix one (1) length (or number
of digits) of bar code:
To fix two (2) different lengths
of bar codes:
1. Scan “START” to enter the
programming mode
2. Scan “Enable fixation(H1)” bar
code
1. Scan “START” to enter
the programming mode
2. Scan “Enable fixation(H4)” bar
code
3. Scan a sample bar code of
the desired length
4. Repeat Step #3, re-scanning
the sample bar code
5. Scan “STOP” to exit the
programming mode
3. Scan a sample bar code of
the desired length #1
4. Scan a sample bar code
of the desired length #2
5. Scan “STOP” to exit the
programming mode
NOTE: Fixation can also be programmed using computer commands through your RS232 by typing
<ESC>7V<CR> followed by <+>2 digit length 1<CR>. 7W would be appropriate for length 2.
Type<+>00<CR> to define either length as no fixed number.
“Fixing the Number of Digits” can only be applied to Code 39, Codabar (NW-7), 2 or 5 and MSI/Plessey.
WPC, Code 93, IATA and Code 128 are not affected.

The scanner can be programmed to transmit a prefix and/or suffix with the decoded data. A Prefix (or a
Suffix) is composed of up to 4 characters. The following steps are used to establish a Prefix that will be
transmitted with the bar code data:
1. Scan Start
2. Scan the bar code representing the symbology to which you wish to add a Prefix
3. Scan the character(s) that will comprise the Prefix. Up to four numeric, alpha or control character(s)
may be used.
4. Scan “STOP” to exit the Programming Mode.
Example: To add the alpha character “A” as a Prefix and “B” as a
Suffix to UPC-A bar code data:
1. Scan “START/END Programming Mode”
2. Scan N1, representing a Prefix for UPC-A
3. Scan 0A, representing the alpha character “A”
4. Scan N6, representing a Suffix for UPC-A
5. Scan 0B, representing the alpha character “B”
6. Scan “START/END Programming Mode”
The same steps are used to establish a Suffix.

Computer Command
The Trigger function is disabled in the default setting. This means that the red scanning light is “ON”
continuously and the scanner is always ready to read. For some applications, you may wish to activate
the scanner only at a specific time. This can be done by enabling the Trigger function. Once in the
“Trigger Enabled” mode, the red scanning light is OFF until the trigger is activated or “pulled.” Either a
hardware trigger or a software trigger pulse may be used to activate the scanner.
The hardware trigger is actuated by pulling Pin #1 (on the standard 9-pin mini-DIN connector) LOW.
The software trigger is actuated by downloading and <ESC> Z <CR> computer command from the host.
(See Scanner Timeout to establish the length of time the scanning light remains ON after the trigger is
activated.)

24. Selecting the Read Mode (continued)
The operation of the scanner in the various read modes is described in the table below. The “Continuous
Read” mode is helpful in positioning the scanner for optimum reading. In “Continuous Read,” the
scanner’s buzzer functions like a Geiger counter, sounding the most active at the position achieving the
greatest number of good reads.

25. Scanner Timeout (Trigger Enabled Mode only)
These commands, which are only applicable in the Trigger Enabled mode, establish the time-out period
after the trigger pulse is received. The Time-out period is the same whether the scanner is operating in
Single, Multiple or Continuous Read mode.

26. Redundant Decoding
The Number of Redundant Decodes determines how many times the scanner must decode a bar code
and obtain the same value before it will transmit the data. For example, if the redundancy is set at three
times, the scanner will not transmit data until it has decoded the bar code and obtained the same values
three times in succession. If it obtains the same value twice in a row, but a different value on the third
read attempt, it will not transmit. If it gets the same value three out of four times, it will not transmit. It
must receive three consecutive, identical reads.
