Section 1  
Introduction and Getting Started  
Product Overview  
The NFT-1125/2135 Series Fixed Position Scanners are miniature, 100/200 scans per second bar code  
readers designed to be easily incorporated into host equipment. CCD scanning technology features 100%  
solid state design with absolutely no moving parts. Durability and reliability are assured.  
Advanced 16-bit 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 NFT-1125/2135 Series 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 following 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 StartProgramsAccessories  
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

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 keyboard 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 scanning 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:  
<Escape> S7 <Carriage Return>  
In this “Trigger Disabled” mode, the red scanner light is always illuminated. You are now ready to scan  
bar codes.  
8) Position the red 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 reading distance.  
This Quick Start-Up procedure will get you started. 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 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 NFT-1125/2135 Series fixed position scanners, the nominal focal distances  
are:  
1126 Side View

Manual No. 25-NFT1121-01  
Series NFT-1121/2135 Mini CCD Fixed Position Scanners  
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. 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 NFT-  
1125/2135 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  
maximum width that the scanner is capable of reading. 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.

2) Avoiding Specular Reflection  
Do not position the scanner at an angle that causes the LED illumination 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 2 to 9 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.

Manual No. 25-NFT1121-01  
Series NFT-1121/2135 Mini CCD Fixed Position Scanners  
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 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 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, 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.

Series NFT-1121/2135 Mini CCD Fixed Position Scanners  
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  
No data is transmitted  
decoded (e.g., print quality was poor)  
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 which 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

No bar code was present

Section 4  
Configuring the Scanner  
Since the operation of the NFT-1125/2135 Series 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 to program the scanner by sending software  
instructions from the host PC to the scanner via the RS232 connection.  
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, however, the scanner is instructed to  
return all parameters to default settings (U4), it will return to the factory default settings shown in the  
following table.

support staff is available to answer any questions or work with you to adapt the scanner to your specific  
situation. We are happy to answer your questions, assist in configuring and positioning the scanner for  
optimum operation, and help resolve any problems you encounter. Call us at 1 (800) 636-0090.  
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.

Manual No. 25-NFT1121-01  
Series NFT-1121/2135 Mini CCD Fixed Position Scanners  
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).  
Note: Where computer commands appear in parenthesis, bar code commands must be used to program the  
scanner.

Manual No. 25-NFT1121-01  
Series NFT-1121/2135 Mini CCD Fixed Position Scanners  
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 inter-  
rupted 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.  
Factory default settings are indicated throughout the following menus by the pointing hand icon (B).

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 program-  
ming mode  
2. Scan “Enable fixation” bar code  
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  
1. Scan “START” to enter the program-  
ming mode  
2. Scan “Enable fixation” 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  
“Fixing the Number of Digits” can only be applied to Code 39, Codabar, 2 or 5 and MSI/Plessey (UPC, Code  
93 and Code 128 are not affected).

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.  
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”

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 #16 (on the standard DB25 female 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.)

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.
