Section 1  
Introduction and Getting Started  
Product Overview  
The NFT 2100 Fixed Position Scanner is a miniature, 200 scan per second, CCD barcode reader designed  
to be easily incorporated into host equipment. The small physical size makes 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 scanner is 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 scanner is encased in a compact, rugged, yet lightweight steel enclosure. The compact size permits  
installation in the tightest areas 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.  
Turn off the power to your PC and connect the scanner to a RS232 communications port. Note: You  
must provide +5 Volt DC power to the scanner. If you are using our standard LHA2107RR1S-054, you  
can utilize power supply, P/N 32-00907-01, by plugging its connector directly into the power jack on the  
DB9 connector. If the power supply is obtained from another source verify that it is identified with the  
CE mark. Turn on the power to the PC.  
1) If you are operating in a Microsoft Windows 95/98/ 2000/ XP environment, you can set the  
communication parameters using Hyper Terminal as follows:  
♦
Open Hyper Terminal. This can be done from Start→Programs→Accessories/  
Communications  
♦
♦
Select Hypertrm.exe to create a New Connection  
In the Connection Description dialog screen enter a name for the new file, like "Opticon". If  
desired, select an Icon. Click OK  
♦
♦
♦
♦
In the Connect To (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 hyper-terminal folder you just created will open. From the File pull-down menu, select  
Properties then click on the Setting Tab  
In the Properties Settings dialog screen, Select Terminal keys for the Function, arrow and  
control key; then Select ANSI for Emulation; the Back scroll buffer line can remain at the  
default 500

Click on the ASCII Setup button. In the ASCII Setup Sending screen, select Line ends with  
line feeds and Echo typed locally so that any keyboard commands you input will appear on  
your screen. In the ASCII Setup Receiving screen, select Append line feeds to incoming line  
ends and Wrap lines that exceed terminal width. Click OK. This returns you to the  
Properties Setting. Click OK  
2) Your PC and the scanner should now communicate. To verify that the scanner and the PC are  
communicating properly, send the following command from your PC keyboard which will request  
software settings to be displayed.  
Send the command in four keystrokes: <Esc> Z3 <Enter>  
Note: Be sure to use capital letters, e.g. “Z3”, not “z3”.  
A series of software setting should be displayed, indicating that good communications have  
been established  
3) A red LED light should be visible. If it is not visible, the scanner may be in a mode that requires  
a “Trigger” Command from the PC to activate it. You can exit that mode by sending the  
following command from your PC keyboard:  
<Esc> S7 <Enter>  
4) The “Trigger” mode will now be deactivated and the red LED light will be continuously  
illuminated.  
This Quick Start-Up procedure will get you started. However, to best understand the full capabilities of  
this scanner, you should read the complete manual.

NFT 2100 CCD Fixed Mount Barcode  
Section 3  
Positioning the Scanner for Optimum Performance  
Achieving Optimum Performance  
Four items greatly impact performance:  
1) Distance (from the scan window) to the bar code  
2) Field of View  
3) Specular Reflection  
4) Quality of Bar Code Labels  
1) Distance to the Bar Code and 'Depth of field'  
The ideal location of the bar code relative to the scanner is at its focal distance, about 1.4" from the front  
of the unit. A bar code located either too near or too far from the scanner will be out of focus for the  
scanner camera causing the scanner to have difficulty decoding what appears to be fuzzy bars and  
spaces.  
Just as with any camera, the scanner has a working depth-of-field (DOF). It can read bar codes that are  
not precisely at its focal distance - maybe a little closer, or a little farther away. The DOF varies based  
on the density of the bar code, i.e., the thicker the bars and spaces the more DOF. Very high density bar  
codes (which have very narrow bars) are readable over a much shorter DOF 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  
NFT 2100 scanner. 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.

2) Reading width or Field of View of the scanner  
The table below shows the field-of-view (FOV) at various distances from the window. The FOV 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. For the NFT 2100, the FOV will be 3.1" at its focal distance of 1.4". Any part of a bar  
code label that is positioned outside of the FOV will make the label unreadable. Good design policy is to  
position the barcode at the center of the FOV where the camera sees best.  
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.

3) Avoiding Specular Reflection  
Do not position the scanner at an angle that causes the LED 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. For optimal performance we recommended pitching the scanner ±13º off the  
perpendicular to the barcode label surface.  
If the bar code label is located on a flat surface, specular reflectivity occurs in the region between ±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, specular reflection may occur at some point along the movement. This is OK, as long as  
there is sufficient regions on the test tube label where the label is out of the specular angle. The  
following diagram indicates the region to avoid:  
α
Aviod this region

±10º  
4) 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  
A method for properly positioning the unit is to program the scanner for Trigger Disable (S7) and  
Continuous Read (S2) modes. The scanner will now 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 position.  
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 creates delay before decoding  
begins, slowing down throughput rate.  
♦
♦
♦
♦
♦
Only enable those symbologies that you will be decoding.  
Eliminate all suffixes and prefixes to reduce transmission time.  
Minimize the number of redundant reads required before transmitting data.  
Transmit the decoded data at the highest baud rate.  
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, 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.

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:  
Decoded data is  
A bar code is scanned and decoded.  
transmitted  
A bar code is scanned but is not decoded  
(e.g., print quality was poor)  
No data is transmitted  
No bar code is present  
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. See Section 33 of Appendix C of this  
manual for details.

Section 4  
Configuring the Scanner  
Since the operation of the NFT 2100 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 commands from the host PC to the scanner via  
the RS232 connection. Most commands will be immediately active, but are not stored into non-  
volatile memory until the store command, Z2, is sent. A few commands, such as changing the  
communication parameters will not be active until they are stored via the Z2 command.  
2. The second method employs specially designed programming bar codes referred to as menu  
commands. Scanning these bar codes instructs the scanner to modify specific parameters. These  
commands are stored into non-volatile memory as soon as the menu command mode is exited.  
Once stored in non-volatile memory, these settings will remain even after powering the unit OFF and  
ON.  
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 non-volatile memory, even if power is interrupted or terminated. If for any reason the  
scanner is instructed to return all parameters to default settings (U2), 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.

for technical support.  
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 paper background is not white, but some color like dark blue, causing poor contrast.  
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 is 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.  
♦
If the com port setting is set to Handshaking, the scanner will not transmit until the CTS signal (RTS  
from Host) is activated.  
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 connector 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.

The NFT 2100 has been examined and found to be a CE Class 1 LED Device according to the relevant  
requirements of IEC 825-1 and corresponding EN 60825-1 (1993-11) including amendment 1 (1997-09)  
and amendment 2 (2001-01).  
The NFT 2100 scanner uses low-power visible LEDs. As with any very bright light source, such as a  
flashlight, you should avoid staring into the light. Momentary exposure to an IEC 825-1 Class 1 LED is  
not known to be harmful.  
A manufacturer’s label, as shown below, indicating the manufacturer, product model, ordering number,  
serial number, CE mark and place of manufacture is affixed to each scanner.

Scanner Servicing and Maintenance  
The NFT 2100 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.  
The NFT 2100 is warranted for 7 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 NFT 2100. 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> or <STX> and followed by a <CR> or <ETX>  
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 that 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 is 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 non-volatile memory and are stored permanently  
(even if the scanners is powered down) or until they are changed again.

NFT 2100 CCD Fixed Mount Barcode  
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 become 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. Note, while you are in the programming mode the scanner will not read  
regular bar codes.  
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 changes you have made, including any changes that were made during previous  
programming.  
Reset All Defaults U2 Command  
This command will return all settings to the defaults that were installed in the factory

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 before the stop character.  
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 be read.

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 modulo seven of the data string. IATA is an acronym for International Air

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 set one or two lengths for all  
symbologies:  
To set one or two lengths for selected  
symbologies:

3. Scan a sample bar code of  
the desired length.  
1. Scan “START” to enter  
the programming mode  
2. Scan “Enable length setting (HK)

3. Scan a sample bar code of  
the desired length #1  
4. Repeat Step #3, re-scanning  
the sample bar code length or a  
different bar code length to get 2  
lengths.  
5. Scan “END” to exit the

“Setting the Number of Digits” can only be applied to Code 39, NW-7, 2 of 5, and MSI/Plessey. WPC,  
Code 93, IATA, and Code 128 are not affected.  
Setting Minimum/Maximum Length  
This option modifies the default minimum length table. To use this option, perform the following steps:  
1. Scan “START” to enter the programming mode  
2. Scan “Enable minimum length for selected codes” (HL)  
3. Scan bar codes of the required type and length.  
4. Scan “END” to end the programming sequence.

For example, if a Code 39 label containing 2 characters were scanned in Step 3 then only Code 39 labels  
would be checked for a minimum length of 2 characters. If a second label had been read in Step 3  
(immediately following the first), then that particular symbology would have been set to its associated  
minimum character length.  
In a similar manner, the maximum length for selected codes can be established by using the “Enable  
maximum length for selected codes” (HM) command.

The Z3 command can be used to instruct the scanner to provide a list of its current software settings  
including prefixes and suffixes.  
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  
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”  
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/Suffix  
3. Scan the character(s) that will comprise the Prefix/Suffix. Up to four numeric, alpha or control  
character(s) may be used. Scanning no characters will delete the Prefix/Suffix  
4. Scan “STOP” to exit the Programming Mode.  
In addition, the scanner can be programmed to transmit a preamble and/or postamble with the decoded  
data. A Preamble and/or postamble can be composed of up to 8 characters each and will apply to all  
symbologies. The following steps are used to establish a Preamble and/or postamble that will be  
transmitted with the bar code data:  
1. Scan Start  
2. Scan the MZ for preamble or PS for Postamble  
3. Scan the character(s) that will comprise the Preamble/Postamble. Up to eight characters may be  
used. Scanning no characters will delete the Preamble/Postamble.  
4. Scan “STOP” to exit the Programming Mode.

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.

30. Quiet Zone Options  
With this option the scanner can decode bar codes that have smaller quiet zone margins than specified  
for the symbology. Be careful when using this option as its use may increase the possibility of partial and  
ghost reads. Do not use smaller margin checks than necessary. If possible, replace the bar codes labels  
with others that have the correct quite zone margins.

31. 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 completed three consecutive, identical “good reads”.  
In the case of a poor label which generates an intermediate “no decode” within a sequence of four scans  
where three of the four have resulted in “good reads”, the scanner will transmit the data after the fourth  
scan. In other words, a “no decode” does not restart the sequence.

33. No read error messages.  
The scanner can be programmed to transmit an error message when no barcode is read. The unit must  
be in trigger mode, then, the error message will be sent at the end of a trigger time out. 2 types of  
messages can be sent. The first type will indicate that no label was present or that nothing was in front  
of the scanner. The second type will indicated that a barcode was present but could not be decoded.  
To program an error message, scan the appropriate command below then scan up to 4 direct input  
characters. To remove the error message, scan the appropriate command below but do not scan any  
direct input characters.
