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

Scanner

♦

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.

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:

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.

Page 9


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.

Decoded data is transmitted

A bar code is scanned but is not decoded

(e.g., print quality was poor)

No bar code is present

No data is transmitted

No data is transmitted

In some applications, when no data is transmitted, it may be important to know why. Was there a bar code present that could not be decoded, or was no bar code present at all?

This requirement is common in applications such as automated blood analysis equipment. Test tubes containing blood samples from many different people are loaded into a rack for automatic analysis. The bar code on each tube ties that sample and the results back to a specific individual. If no bar code data is transmitted it is critical to understand the reason.

Your Opticon scanner, when operated in the Trigger Enabled mode, can be programmed to transmit an error message indicating whether or not a bar code was present. 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 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.

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 (

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.

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.

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.

Page 16


Scanner

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.

This command will return all settings to the defaults that were installed in the factory

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:

1. Scan “START” to enter the programming mode.

2. Scan “Enable length setting

(H1) for all symbologies”.

3. Scan a sample bar code of the desired length.

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 programming mode

To set one or two lengths for selected symbologies:

1. Scan “START” to enter the programming mode

2. Scan “Enable length setting

(HK) for selected symbologies”.

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 programming mode

“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.

Page 38


Scanner

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.

Example: To add the alpha character “A” as a Prefix and “B” as a

The Trigger function is not enabled in the default setting. This means that the LEDs are “ON” and ready to scan until the trigger mode is set by the S8 command.

Once in the trigger mode, the host can trigger the unit by sending a <ESC> Z <CR> command. (See

Scanner Timeout to establish the length of time the scanning light remains ON after the trigger is activated.) A hardware trigger can also be used to turn the scanner ON.

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.

Read

(S1)

After receiving a trigger pulse, scanner will read multiple, different bar codes in succession until it times out. (Each read will reset the scanner’s time out)

Scanner may not read the same bar code twice if they are consecutive.

28. Scanner Timeout (Trigger Enabled Mode only)

These commands, which are only applicable in the Trigger Enabled mode, establish the time-out period after the trigger pulse is received. In Single Read Mode, the time out is terminated upon a good read.

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.
