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

♦ 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.

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.

20 mil 0.8 2.0 1.2
40 mil 0.9 2.4 1.5

* measured from front edge of scanner

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.

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:

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.

Scanner

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.

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 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.

The scanner can be programmed by sending software commands from the host PC to the scanner via

1.
the RS232 connection. Most commands will be immediately active, but are not stored into non­volatile 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.

The second method employs specially designed programming bar codes referred to as menu

2.
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 (

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 [phone], and ask
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.

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-of­warranty 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 left­hand 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.

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.

Scan the “Start/End” bar code. This instructs the scanner to exit the Programming Mode.

3.

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.

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
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.
