Section 1 Introduction and Getting Started
Product Overview
The NLB-9625/9645 Series Fixed Position Scanners are miniature, 33 or 200 scans per second, laser bar code readers designed to be easily incorporated into host equipment. Utilizing a solid state laser diode and a brushless motor results in a minimum of wear on parts and high performance. The scanner is encased in a rugged steel enclosure to assure durability and reliability.
Advanced 16-bit microprocessor technology coupled with Opticons proven decoding algorithms result in 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.
NLB 9625/9645 Series laser scanners are encased in compact, rugged steel enclosures. The compact size permits installation in the tightest areas. Scanners are available in both front and side view configurations allowing great flexibility in mounting and positioning the scanner for optimum performance.
Quick Start-Up Procedure
This section is for those who wish to start using the scanner before reading the complete manual. In only a few steps the scanner will be operable.
1) Turn off the power to your PC and connect the scanner to an RS232 communications port. Note: You must provide +5 Volt DC power to the scanner. This can be accomplished using the power supply and patch cable available from Opticon. Turn on the power to the PC.
2) Using communications software (e.g., Procom), set the communication parameters: 9600 baud, 1 Start / Stop Bit, 8 Data Bits, No Parity, No Handshaking, No Flow Control.
3) If you are operating in a Microsoft Windows 3.1 environment, skip to Step 5.
4) If you are operating in a Microsoft Windows 95 environment, you can set the communication parameters using Hyper Terminal as follows:
Open Hyper Terminal. This can be done from Start→ProgramsAccessories Select Hypertrm.exe to create a New Connection. In the Connection Description dialog screen enter a name for the new file. If desired, select an
Icon. Click OK.
In the Phone Number dialog screen, in the box entitled: Connect using. select the communication
port, for example, Direct to Com 1. Click OK.
In the Com 1 Properties screen, enter the appropriate Port Settings:
Bits per second = 9600 Data bits = 8 Parity = None Stop Character = 1 Handshaking = None Click OK.
The HyperTerminal folder you just created will open. From the File pull-down menu, select
Properties, then click on the Setting Tab.

Series NLB-9625/9645 Mini Laser Fixed Position Scanner
In the Properties Settings dialog screen:
Select Terminal keys for the Function, arrow and control key Select ANSI for Emulation, The Backscroll buffer line can remain at the default 500
Click on the ASCII Setup button. In the ASCII Setup screen, select Echo typed locally so that any key-
board commands you input will appear on your screen. Click OK. This returns you to the Properties Setting. Click OK. Your PC and the scanner should now communicate. Skip to Step 6.
5) In a Microsoft Windows 3.1 environment, set the communication parameters using the Terminal func­tion of Windows.
From Windows Program Manager Main Menu, select Terminal From the Terminal menu, select Settings From the Settings menu, select Terminal Emulation Set the emulation to TTY (generic) From the Settings menu, select Terminal Preferences and select the following:
Terminal Modes: Line Wrap / Local Echo / Sound CR /LF: Inbound, Outbound Columns: 80
From the Settings menu, select Communications. Select the COM port and set communication parameters as shown in Step 2, including no flow
control.
6) To verify that the scanner and the PC are communicating properly, send the following command from your PC keyboard to activate the scanners buzzer.
Send the command: <Escape> V5 <Carriage Return>
Note: Be sure to use capital letters (e.g. V5, not v5).
The buzzer should sound, indicating that good communications have been established.
7) A red laser light should be visible. Do not stare into the laser light. If the light is not visible, the scanner may be waiting for a Trigger Command from the host to activate it. Send the following computer com­mand to place the scanner into the Triggered Disabled mode:
<ESC> S7 <CR>
In this Triggered Disabled mode, the red laser light is always illuminated. You are now ready to scan barcodes.
8) Position the red laser light of the scanner over the bar code symbol to be read. When the bar code symbol is decoded, the scanner will beep and transmit the data to the screen of your PC. You may have to move the scanner closer or farther away from the bar code symbol in order to locate the best distance for reading.
This Quick Start-Up procedure will get you started reading bar code symbols. However, in order to best understand the full capabilities of this scanner, you should read the complete manual.

Section 3 Positioning the Scanner
Getting Optimum Performance
Three items greatly impact scanner 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 NLB-9625/9645 Series fixed position laser scanners, the nominal focal distances are:
9626 Side View3.5 in (88.9 mm) 9627 Front View5.6 in (142.3 mm) 9646 Side View 4.2 in (107 mm) 9647 Front View 5.2 in (132 mm)

Manual No. 25-NLB0045-01
Series NLB-9625/9645 Mini Laser Fixed Position 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 typical depth-of-field (closest to farthest reading distances) for the NLB­9625/9645 Series 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 its focal distance rather than at the extremes of its depth-of-field.

Readable Bar Code Width (Field-of-View)
The following table shows the field-of-view at various distances from the window. The field-of-view is the max. width that the scanner is capable of reading. A bar code label positioned anywhere within this field-of­view 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 scanner at its focal distance and at the center of the field-of-view. Do not position it near the extremes of the reading range.

2) Avoiding Specular Reflection
Do not position the scanner at an angle that causes the laser scan line 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 +3 degrees off perpen­dicular (See diagram in Section 2). 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.

3) Quality of 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 ON continuously 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 100 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 100 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.
Heres how to perform the Read Rate Test:
1) Program the scanner for Continuous Read (S2) and Trigger Enabled (S8).
2) Instruct the scanner to enter the Read Rate Test mode (ZA).
3) Locate the scanner in the desired position relative to a test bar code then enter a Z command. The scanner will read the bar code once and store it in memory.
4) Enter another Z command. The scanner will scan the bar code 100 times and then transmit the Read Rate Percentage to the host.
5) Steps 3 and 4 can be repeated as often as desired, moving the scanner to new locations before each test.
6) Exit the Read Rate Test mode (ZG).

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 max. 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, 19200 baud. Disable both the hardware and software buzzer functions. If you need a buzzer, use the hardware buzzer rather than the software buzzer.
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.

Manual No. 25-NLB0045-01
Series NLB-9625/9645 Mini Laser Fixed Position Scanner
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 A bar code is scanned but is not
decoded (e.g., print quality was poor) No bar code is present
Decoded data is transmitted
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 that indicates 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 Scanner Transmits Bar code was present and correctly decoded Decoded Data No bar code was present <STX> ? <ETX> Bar code was present but could not be decoded <STX> > <ETX>

Section 4 Configuring The Scanner
Since operation of the NLB 9625/9645 Series laser scanner is microprocessor controlled, it is possible to modify or program its operation to match your specific application. Changes in parameter settings can be changed or programmed in two ways. The first method employs specially designed programming bar codes, which instruct the scanner to modify specific parameters. The second is that the scanner can also be pro­grammed by sending software instructions from the host PC to the scanner via the RS232 connection.
Programming Menus & Commands
Two different methods can be used to program parameters to configure the scanner:
a. Programming via Bar Codes from a menu page; or b. Programming via Computer Commands
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.
Programming via Bar Codes
Use the following steps to program parameters via the bar code menu:
1) Scan the START 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 scanned. Note: Because of the close proximity of bar codes on the menu, approaching the desired bar codes from the side of the page will ensure that the only correct bar code is scanned.
3) Scan the STOP bar code. This instructs the scanner to exit the Programming Mode.
All the parameters that are programmed via bar codes are retained in non-volatile memory and stored perma­nently (even if the scanner is powered down) or until they are changed again.
Page 13
Page 20
Manual No. 25-NLB0045-01
Series NLB-9625/9645 Mini Laser Fixed Position Scanner
Programming via Computer Commands
Various 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:
1) Only upper case letters are recognized, e.g. AB , not ab
2) Each Command normally consists of two characters
3) Downloading of software commands cannot be grouped together. Each command must be preceded by <ESC> and followed by a <CR>
Parameters changed by downloading software commands remain in effect only while power is supplied to the scanner. If power is interrupted or terminated, the parameters return to their original settings. However, parameters programmed by downloaded commands can be stored permanently by transmitting a Z2 Computer Command to the scanner after the commands are sent. This instructs the scanner to store the changed parameter in non-volatile memory. The scanner will then retain the setting permanently or until it is changed.
It is not necessary to send a Z2 command after each parameter is changed. One Z2 command will save all changes. If you want to program the scanner so that it will only decode a Code 128 bar code, you would send the following command:
<ESC> A6 <CR>
The scanner will now only decode Code 128 bar codes. It will ignore any other type of bar code. The scanner will retain this setting until power is shut off. Then it will revert to its original setting. If you want to retain this setting permanently, you would send the following commands:
<ESC> A6 <CR> then <ESC> Z2 <CR>
The Z2 command stores the changed parameter in non-volatile memory. The scanner will now retain that setting even after power is terminated.
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.

Factory Default Settings
Factory default settings are indicated by the word (Default) throughout the Programming menus located in Appendix A.
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, however, the scanner is instructed to return all parameters to default settings, it will return to the factory default settings shown in the following table.

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.

Section 6 Scanner Labeling
CDRH Class II
The NLB 9625/9645 Series scanner complies with Center for Devices and Radiological Health (CDRH) regula­tion 21, CFR Subchapter J.
A NLB 9625/9645 Series scanner uses a low-power, visible laser. As with any very bright light source, such as the sun, the user should light beam. Momentary exposure to a CDRH Class II laser is not known to be harmful.
CAUTION
LASER PRECAUTION:
DO NOT ST ARE INTO BEAM
Laser Caution Label
ID/ Certification Label
Required safety label as it appears on the scanner.
Note: Do not open the scanner. The scanner contains 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 you to laser energy. Laser diode power of up to 2 mWatt average could be accessible in the interior of the scanner. If a NLB 9625/9645 Series scanner is incorporated or interfaced to other equipment, that equipment should include an 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.
CAUTION: Use of controls, adjustments or performance of procedures others than those specified herein may result in hazardous visible light exposure.

Introduction
Two different methods can be used to program parameters to configure the scanner:
a) Programming via bar codes from a menu page; or b) Programming via computer commands
Programming via Bar Codes
Use the following steps to program parameters via the bar code menu:
1) Scan the START/END Programming Menu bar code. This instructs the scanner to enter the Program­ming Mode. The scanner will beep intermittently while in this mode.
2) Scan the bar code(s) associated with the desire parameter(s). The scanner will beep when the bar code is scanned. Note: Because of the close proximity of bar codes on the menu, approaching the desired bar codes from the side of the page will ensure that only the desired bar code is scanned.
3) Scan the START/END Programming Menu bar code. This instructs the scanner to exit the Program­ming Mode.
All the parameters that are programmed via bar codes are retained in non-volatile memory and stored perma­nently (even if the scanner is powered down) or until they are changed.
Programming via Computer Commands
Various 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 typically consists of two characters. Downloading of software commands cannot be grouped together. Each command must be pre­ceded by <ESC> (Escape) and followed by <CR> (Carriage Return).
Factory default settings are indicated throughout the following menus by the pointing hand icon (
NOTE: Where computer commands appear in parenthesis, bar code commands must be used to program the scanner.
B
).
Page 22
Page 29
Manual No. 25-NLB0045-01 Series NLB-9625/9645 Mini Laser Fixed Position Scanner
Parameters modified by downloading software commands remain in effect only while power is supplied to the scanner. If power is interrupted or terminated, the parameters return to their original settings. However, param­eters programmed by downloaded commands can be stored permanently by transmitting a Z2 computer command to the scanner after the commands are sent. this instructs the scanner to store the changed parameter(s) in non-volatile memory. The scanner will then retain the setting(s) permanently or until changed.
It is not necessary to send a Z2 command after each parameter is changed. One Z2 command will save all changes.
Example: If programming the scanner to decode only Code 128 bar code were desired, the following command would be used:
<ESC> A6 <CR>
The scanner will now only decode Code 128 bar codes and will ignore other types of bar code. The scanner will retain this setting until power is interrupted or terminated, and will then revert to its original setting. If retaining this setting permanently is desired, the following command would be used:
<ESC> A6 <CR> <ESC> Z2 <CR>
The Z2 command stores the modified parameter in non-volatile memory. The scanner will not retain this setting even after power is terminated.

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:
1. Scan START to enter programming mode
2. Scan Enable fixation bar code
3. Scan a sample bar code of desired length
4. Repeat Step #3, re-scanning the sample bar code
5. Scan STOP to exit programming mode

Manual No. 25-NLB0045-01
Series NLB-9625/9645 Mini Laser Fixed Position Scanner
Creating a Prefix and/or Suffix
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 to enter the Programming Mode.
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 4 numeric, alpha or control character(s) may be used.
4. Scan STOP to exit the Programming Mode.
The same steps are used to establish a Suffix.
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

Buzzer Operation
The buzzer can be activated either by a hardware or software command. The hardware buzzer is faster, allowing greater scanning throughput. But, it is fixed and can not be adjusted. The sound and duration of the software buzzer can be programmed. These commands are useful in verifying that proper communication exists between the scanner and the host. They can only be invoked via 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 if 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 #16 (on the standard DB25 female connector) LOW. The software trigger is actuated by downloading and <ESC> Z <CR> computer command from the host.
Activate the trigger; turns on the
red scanning light

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.

After receiving a trigger pulse, scanner will read multiple, different bar codes in succession until it times out.
Scanner will not read the same bar code twice if they are consecutive.
Scanner will read the same bar code continuously after receiving a trigger pulse until scanner times out.
Scanner will read only one bar code after receiving a trigger pulse.

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.
