Figure 7. Skew, Tilt, and Pitch Angles
The Skew angle is represented by the value S shown. Position the reader to assure at least 10° for the Skew angle. This avoids the direct reflection of the laser light emitted by the barcode scanner. For the raster version, this angle refers to the most inclined or external raster line, so that all other raster lines assure more than 10° Skew.
The Tilt angle is represented by the value T shown. Position the reader to minimize the Tilt angle. By using the Reconstruction Reading Mode software parameter, the tilt angle is less critical and can be decoded even if the
scan line doesn’t cross the entire code. The Pitch angle is represented by the value P. Position the reader to minimize the Pitch angle.

5.3.1 Auto Learn
If you are configuring your scanner using SMART-TEACH, you must start with the Auto Learn procedure.
1. Hold the SMART-TEACH push button pressed until the LEARN LED is on.
2. Release the button to enter the Auto Learn function. The reader begins to automatically detect and recognize barcodes (by type and length) that are presented to it4. The laser turns on and the LEARN LED blinks to indicate the ongoing process.
1. Place the desired barcode on the scanline.
2. Wait until the LEARN LED is steady ON (indicating the reader has detected the barcode).
3. Repeat, if needed, the above two steps to program up to 10 different barcodes (the LEARN LED returns to the blinking state for the next code). If more than one barcode is detected in the scan line, the Multi Label mode is enabled (refer to TCNM-AD/EX/SP Family Software Configuration Parameter Guide help file).
3. Exit the process by pressing the SMART-TEACH push button once. The scanner restarts at the end of the process, and then the detected barcodes are automatically configured in the scanner memory.
NOTE: If the barcode cannot be read because of low contrast or excessive ambient light, you can perform the AutoSetup function to optimize the optical parameters. Then you can perform Auto Learn to recognize the barcode symbology.
NOTE: On exit from Auto Learn, the following parameters are forced: Code Combination = Single Label, Reading Mode = Linear. If necessary, these parameters can be changed through GeniusPlus.
5.3.2 Auto Setup (Optional)
At the end of the Auto Learn procedure, you may follow the Auto Setup procedure to set up the reading parameters.
1. Hold the SMART-TEACH push button pressed until the SETUP LED is on.
2. Release the button to enter the Auto Setup function.
3. Once entered, if a barcode label is positioned in front of the scanline, the scanner automatically performs the optimal setup of the reading parameters for that specific barcode.
1. Place the desired barcode on the scanline.
2. Enter the Auto Setup function (the laser turns on and the SETUP LED blinks to indicate the ongoing process).
3. Wait until the SETUP LED stays steady ON (indicating the reader has detected the barcode).
This procedure ends either when the barcode is successfully decoded or after a timeout of about 7 seconds. The scanner restarts at the end of the process, and then the optimized reading parameters for that barcode are automatically configured in scanner memory.
18
NOTE: If your application has been configured using SMART-TEACH, go to STEP 5.
4
In case of Programming Barcodes, refer to the “Setup Procedure Using Programming Barcodes” document in the product CD.
Page 19
TCNM AD/EX Barcode Scanner
5.3.3 Reset Scanner to Factory Default (Optional)
To reset the scanner to the factory default values, hold down the SMART-TEACH push button while powering up the scanner. At the end of the procedure (about 5–6 seconds), the Configuration and Environmental parameters are reset, and all LEDs blink simultaneously three times.
5.4 STEP 4 – Installing GeniusPlus Configuration Program
GeniusPlus is a scanner configuration tool that provides several important advantages:
• Wizard approach for new users
• Multi-language version
• Defined configuration directly stored in the reader
• Communication protocol independent from the physical interface allowing to consider the reader as a remote object to be configured and monitored
To install GeniusPlus, insert the GeniusPlus CD-ROM, wait for the CD to autorun, and follow the installation procedure. The software is compatible with Windows 98, 2000/NT, XP, Vista, Windows 7, and Windows 8.
This configuration procedure assumes scanner connection to a TCNM-ACBB1. GeniusPlus, running on a laptop computer, is connected to the scanner auxiliary port through the TCNM-ACBB1 9-pin connector. To communicate with the scanner, GeniusPlus performs an auto baud rate detection starting from its default parameters, which are 115200, 8, N, 1. These parameters can also be set in the GeniusPlus Tools > Options > Communications window.
5.4.1 Wizard for Quick Reader Setup
After installing the GeniusPlus software program, the following window appears asking the user to choose the desired configuration level.
The Wizard option is advised for rapid configuration or new users because it shows a step-by-step scanner configuration.

1. Click Create New to create a new configuration
a. Select a barcode and drag it into one of the slots at the bottom. Click Next to configure the selected
barcode(s) on the following screen(s).
b. Select Operating Mode and click Next.
On Line operating mode requires the reader to be connected to an External Trigger/Presence Sensor using I1A and I1B inputs.
Automatic operating mode does not require connection to an external Presence Sensor. When working in this mode, the reader is continuously scanning while the reading phase is activated each time a barcode enters the reader reading zone. The reader stops reading after an N number of scans without a code. Barcode characters are transmitted on the serial interface. In case of a failed reading phase, no message is sent to the host computer.

6.1 SMART-TEACH Human Machine Interface
SMART-TEACH is the intuitive Human Machine Interface designed with the precise goal of improving ease of installation and maintenance.
Status and diagnostic information are clearly presented by means of five colored LEDs, whereas the single multi-function key gives immediate access to relevant functions:
• Autosetup—to self-optimize reading performance in demanding application
• Autolearn—to self-detect unknown barcodes
• Test Mode with bar-graph visualization—to check static reading performance
The colors and meaning of the five LEDs when in the one of the operating modes (On Line, Automatic, or Continuous) are illustrated in Indicators on page 11.

6.1.2 Test Mode Function
In Test Mode, the bar graph on the five LEDs is activated and if the scanner starts reading barcodes, the bar graph shows the Good Read Rate. In case of no read condition, only the STATUS LED is on and blinks.
To exit the Test Mode, press the SMART-TEACH push button once.
6.1.2 AutoLearn Function
In AutoLearn, the reader starts to automatically detect and recognize barcodes (by type and length) that are presented to it. The laser turns on and the LEARN LED blinks to indicate the ongoing process.
The procedure is as follows:
1. Place the desired barcode on the scanline.
2. Wait until the LEARN LED stays steady on (indicating the reader has detected the barcode).
3. Repeat, if needed, the above two steps to program up to 10 different barcodes (the LEARN LED returns to the blinking state for the next code). If more than one barcode is detected in the scan line, the Multi Label mode is enabled.
4. Exit the process by pressing the SMART-TEACH push button once.
The scanner restarts at the end of the process, and the detected barcodes are automatically configured in scanner memory.
6.1.2 AutoSetup Function
In AutoSetup, if a barcode label is positioned in front of the scanline, the scanner automatically performs the optimal setup of the reading parameters for that specific barcode.
The procedure is as follows:
1. Place the desired barcode on the scanline.
2. Enter the AutoSetup function (the laser turns on and the SETUP LED blinks to indicate the ongoing process).
3. Wait until the SETUP LED stays steady on (indicating the reader has detected the barcode).
This procedure ends either when the barcode is successfully decoded or after a timeout of about 7 (seven) seconds.
The scanner restarts at the end of the process, and then the optimized reading parameters for that barcode are automatically configured in scanner memory.

7 TCNM-ACBB1 Electrical Connections
All laser barcode scanners are equipped with a cable terminated by a 25-pin male D-sub connector for connection to the power supply and input/output signals. We recommend making system connections through a TCNM-ACBB1 connection box because they offer the advantages of easy connection, device replacement, and filtered reference signals.
This table lists the pinout of the TCNM-ACBB1 terminal block connectors. Use this pinout when the barcode scanner is connected using the TCNM-ACBB1.

7.2 Main Serial Interface
The signals relative to the following serial interface types are available on the TCNM-ACBB1 spring clamp terminal blocks. If the interface type is not compatible with the current communication handshaking, then the system forces the handshake
to none. Set the main interface type and the relative parameters (baud rate, data bits, etc.) using the GeniusPlus utility program. Details regarding the connections and use of the interfaces are given in the next sections.
7.2.1 RS232 Interface
The serial interface is used for point-to-point connections; it handles communication with the host computer and allows both transmission of code data and the programming of the scanner. This is the default setting.
The following pins are used for RS232 interface connection.

7.4 Inputs
There are two opto-coupled polarity insensitive inputs available on the scanner: Input 1 (External Trigger) and Input 2, a generic input. The electrical features of both inputs are:
Maximum voltage: 30V dc Maximum current: 12 mA (scanner) + 12 mA (TCNM-ACBB1)
An anti-disturbance filter is implemented in software on both inputs so that the minimum pulse duration is approximately 5 milliseconds. This value can be increased through the software parameter Debounce Filter, see the software help file.

7.4.1 Code Verifier
If the barcode scanner is used as a Code Verifier, the verifier code can be configured in software through the GeniusPlus configuration program. However it is also possible to use one of the inputs to trigger when the scanner should store a code read as the verifier code.
To read the verifier code:
1. Enable the Code Verifier parameter, and
2. Save the configuration parameters to allow correct Code Type reading to the scanner.
When the selected input is activated, the next read code is stored as the verifier code in the scanner's non-volatile (Flash) memory. For more details see the Verifier Parameters in the TCNM-AD/EX/SP Family Software Configuration Parameter Guide help file.

The meaning of Output 1 and Output 2 can be defined by the user (No Read, Right, Wrong, etc.). By default, Output 1 is associated with the No Read event, which activates when the code signaled by the external trigger is not decoded. Output 2 is associated with the Complete Read event, which activates when all the selected codes are correctly decoded.
The output signals are fully programmable being determined by the configuration of Activation/Deactivation events, Deactivation Timeout or a combination of the two.

8 Typical Layouts
The following typical layouts refer to system hardware configurations. Dotted lines in the figures refer to optional hardware configurations within the particular layout. These layouts also require the correct setup of the software configuration parameters.
8.1 Point-to-Point
In a serial interface layout, data is transmitted to the Host on the main serial interface.
• In Local Echo communication mode, data is transmitted on the RS232 auxiliary interface independently from the
• When On Line Operating mode is used, the scanner is activated by an External Trigger (photoelectric sensor) when

8.2 Pass-Through Mode
Figure 32. Pass-Through Layout
Pass-through mode allows two or more devices to be connected to a single external serial interface. Each barcode scanner transmits the messages received by the Auxiliary interface onto the Main interface. All messages are passed through this chain to the host.
When On Line Operating mode is used, the scanner is activated by an External Trigger (photoelectric sensor) when the object enters its reading zone.
Applications can be implemented to connect a device such as a hand-held reader to the Auxiliary port of the last scanner in the chain for manual code reading capability.

9 Reading Features
9.1 Advanced Code Reconstruction
The traditional way of barcode reading could be called “Linear Reading”. In this case, the laser beam crosses the barcode symbol from its beginning to its end as shown in the following figure:
Figure 33. Linear Reading
In Advanced Code Reconstruction (ACR) mode it is no longer necessary for the laser beam to cross the label from beginning to end. With just a set of partial scans on the label (obtained using the motion of the label itself), the scanner is able to “reconstruct” the barcode. A typical set of partial scans is shown in the figure below:
None of the partial scans contains the whole label. The decoder aligns each partial scan correctly and combines them to obtain the entire code. The alignment is performed by calculating the time difference from one partial scan to another using a reference code element. ACR therefore has an intrinsic ability to increase the reading percentage of damaged codes as in the examples below:

Figure 35. ACR Readable Codes
ACR is disabled by default but can be enabled for the following code types:
• Code 25 Interleaved
• Code 39 Family
• Codabar
• GS1 DataBar
• Code 128/EAN128
• EAN/UPC (without Add-Ons)
• Code 93
• GS1 DataBar Expanded
9.1.1 Important Advanced Code Reconstruction Reading Conditions
• Do not use Advanced Code Reconstruction (ACR) for omni-directional reading stations
• Code concatenation and ACR are not compatible and therefore cannot be enabled simultaneously
• Stacked codes and ACR are not compatible
• Codes shorter than 4 digits, while readable linearly, cannot be reconstructed in ACR
NOTE: To maximize scanner performance in Advanced Code Reconstruction Reading applications:
• Enable only the code symbologies used in the application and disable any code symbologies not used in the application
• Reconstruct only one code label at a time
• Use conveyor speeds less than or equal to 1.0 m/s
9.1.2 Tilt Angle for Advanced Code Reconstruction
The most important parameter in Advanced Code Reconstruction is the value of the maximum tilt angle (α maximum) under which the code reconstruction process is still possible.

NOTE: Although tilt angles of 45° can be obtained, barcode scanners are not designed to create omni­directional reading stations using two scanners in an X-pattern.
9.1.3 Advanced Code Reconstruction Reading Conditions
The following tables describe the minimum code height requirements (in mm) for standard ACR applications depending on the code symbology and the given reading conditions.

9.2 Linear Code Reading
The number of scans performed on the code by the barcode scanner and therefore the decoding capability is influenced by the following parameters:
• Number of scans per second
• Code motion speed
• Label dimensions
• Scan direction with respect to code motion
At least five scans during the code passage should be allowed to ensure a successful read.
9.2.1 Step-Ladder Mode
If scanning is perpendicular to the code motion direction, the number of effective scans performed by the reader is given by the following formula:
SN = [(LH ÷ LS) × SS] – 2
where:
SN = number of effective scans LH = label height (in mm) LS = label movement speed in (mm/s) SS = number of scans per second
42
Page 43

TCNM AD/EX Barcode Scanner
Figure 38. "Step-Ladder" Scanning Mode
For example:
TCNM-EX (800 scans/sec.) for a 25 mm high code moving at 1250 mm/s performs: [(25 ÷ 1250) × 800] – 2 = 14 effective scans
TCNM-AD (500 scans/sec.) for a 25 mm high code moving at 1000 mm/s performs: [(25 ÷ 1000) × 500] – 2 = 10 effective scans
9.2.2 Picket-Fence Mode
If scanning is parallel to the code motion, the number of effective scans is given by the following formula:
SN = [((FW - LW) ÷ LS) × SS] – 2
where:
SN = number of effective scans FW = reading field width (in mm) LW = label width (in mm) LS = label movement speed (in mm/s) SS = scans per second

For example:

TCNM-AD (500 scans per sec.), for a 60 mm wide code moving in a point where the reading field is 160 mm wide at a 1500 mm/s speed, performs: [((160 – 60) ÷ 1500) × 500] – 2 = 31 effective scans

11 Troubleshooting
11.1 General Guidelines
When wiring the device, pay careful attention to the signal name (acronym) on the TCNM-ACBB1 spring clamp connectors. If you are connecting directly to the scanner's 25-pin connector, pay attention to the pin number of the signals.
If you need information about a certain reader parameter, refer to the GeniusPlus program help files. Either connect the device and select the parameter you are interested in by pressing the F1 key, or select Help > Parameters Help from the command menu.
If you are unable to fix the problem and need to contact Banner Engineering Corp, provide (if possible) the Device Configuration files (*.ddc). Connect through GeniusPlus and click the Save icon from the toolbar. Also note the device's model, serial number, and order number.
11.2 Troubleshooting Guide
Problem Power On: the “Power On”/”Ready”
LED is not lit
On Line Mode: TRIGGER LED is not lit (when external trigger activates)
On Line Mode: TRIGGER LED is correctly lit but nothing happens (no reading results)
Serial On Line Mode: the reader is not triggered (no reading results)
On Line Mode and Serial On Line:
Reader doesn’t respond correctly to the expected external signals end
SMART-TEACH functions do not work. LEDs light up but do not allow access to the functions
Solution
• Is power connected?
• If using rail power, does the rail have power?
• If using TCNM-ACBB1, does it have power (check the switch and LED)?
• Measure voltage either at pin 13 and pin 25 (for 25-pin connector) or at spring clamp V dc and GND (for TCNM-ACBB1).
• Is the sensor connected to I1A and I1B spring clamps (for TCNM-ACBB1) or to pins 18 and 19 (for 25-pin connector)?
• Is power supplied to the sensor?
• Are the sensor LEDS working correctly?
• Is the sensor/reflector system aligned?
• Is the software configuration consistent with the application condition (operating mode, etc.)?
• In the GeniusPlus program select the Operating Mode branch and check for related parameters.
• In the GeniusPlus program select the Operating Mode branch and check if Serial On Line is selected in the On Line Options.
• Are the Start – Stop characters correctly assigned?
• Is the serial trigger source correctly connected and configured?
In the GeniusPlus program select the Operating Mode branch and check the Reading Phase Timeout parameter.
The SMART-TEACH functions do not work if the scanner motor or laser are turned off. Check if the motor or laser are turned off through the following parameters:
• Beam Shutter = enabled
• Scan Speed = Motor Off
• Energy Saving > Serial Motor Off has been sent
Reading: Not possible to read the target barcode (always returns No Read) or the Auto Setup procedure Fails
50
Check the synchronization of reading pulse with object to read: Is the scan line correctly positioned?
Place the barcode in the center of the scan line and run Test mode (selectable by GeniusPlus as an Operating Mode). If you still have trouble, check the following:
• Is the reading distance within the allowed distance (see reading diagrams)?
• Is the Tilt angle too large?
• Is the Skew angle less than 10° (direct reflection)?
• Choose the Code Definition branch and enable different Code Symbologies (except Pharmacode). Length = Min and Max (variable).
• Is the barcode quality sufficient?
• If you had no success, perform the test using the BARCODE TEST CHART included with the product.

Problem Solution Communication: Device is not
transmitting anything to the host
• Is the serial cable connected?
• Is the correct wiring respected?
• Are serial host settings equivalent to the serial device setting?
• If using TCNM-ACBB1, make sure that the RS485 termination switch is positioned to OFF.
Communication: Data transferred to the host are incorrect, corrupted, or incomplete
• In the GeniusPlus program select the Data Communication Settings/Data Format/Standard Parameters branch and check the Header, Separators, and Terminator values
• Check the Code Field Length and Fill Character values.
• Are the COM port parameters correctly assigned?
Communication: Always returns the Reader Failure Character (<BEL>

14 Glossary
A
ACR (Advanced Code Reconstruction)
This powerful code reconstruction technology considerably increases the code reading capability in the case of damaged or very tilted barcodes.
Barcode
A pattern of variable-width bars and spaces that represents alphanumeric data in machine­readable form. The general format of a barcode symbol consists of a leading margin, start character, data or message character, check character (if any), stop character, and trailing margin. Within this framework, each recognizable symbology uses its own unique format.
Barcode Label
A label that carries a barcode and can be affixed to an article.
CDRH (Center for Devices and Radiological Health)
This organization (a service of the Food and Drug Administration) is responsible for the safety regulations governing acceptable limitations on electronic radiation from laser devices. Banner devices are in compliance with the CDRH regulations.
Decode
The process of translating a barcode into data characters using a specific set of rules for each symbology.
EAN
European Article Number System. The international standard barcode for retail food packages.
FLASH
An on-board non-volatile memory chip.
Half Duplex
Transmission in either direction, but not simultaneously.
Aperture
Term used on the required CDRH warning labels to describe the laser exit window.
B
Baud Rate
A unit used to measure communications speed or data transfer rate.
C
Code Positioning
Variation in code placement that affects the ability of a scanner to read a code. The terms Pitch, Skew, and Tilt deal with the angular variations of code positioning in the X, Y and Z axes. Variations in code placement affect the pulse width and therefore the decoding of the code. Pulse width is defined as a change from the leading edge of a bar or space to the trailing edge of a bar or space over time. Pulse width is also referred to as a transition. Tilt, pitch, and skew affect the pulse width of the code.
D
Decoder
As part of a barcode reading system, the electronic package that receives the signals from the scanner, performs the algorithm to interpret the signals into meaningful data, and provides the interface to other devices. The decoder is normally integrated into the scanner.
E
F
Full Duplex
Simultaneous, two-way, independent transmission in both directions.
H
Host
A computer that serves other terminals in a network, providing services such as network control, database access, special programs, supervisory programs, or programming languages.

I
Interface
A shared boundary defined by common physical interconnection characteristics, signal characteristics and meanings of interchanged signals.
L
LED (Light Emitting Diode)
A low power electronic device that can serve as a visible or near infrared light source when voltage is applied continuously or in pulses. It is commonly used as an indicator light and uses less power than an incandescent light bulb but more than a Liquid Crystal Display (LCD). LEDs have extremely long lifetimes when properly operated.
M
Multidrop Line
A single communications circuit that interconnects many stations, each of which contains terminal devices. See RS485.
P
Parameter
A value you specify to a program. Typically parameters are set to configure a device to have particular operating characteristics.
Picket-Fence Orientation
When the barcode’s bars are positioned vertically on the product, causing them to appear as a

The position of a scanner or light source in relation to the target of a receiving element.
Protocol
A formal set of conventions governing the formatting and relative timing of message
exchange between two communicating systems. picket fence. The first bar will enter the scan window first.
Pitch
Rotation of a code pattern about the X-axis. The normal distance between center line or adjacent characters.
R
Raster
The process of projecting the laser beam at varied angles spaced evenly from each other. Typically, the mirrored rotor surfaces are angled to create multiple scan lines instead of a single beam.
Resolution
The narrowest element dimension, which can be distinguished by a particular reading device or
RS232
