2-2 Connecting the Control

Source

This section describes how to connect the SR-750 Series and the power source.

Power supply to the SR-750 Series

There are 2 methods employed for connecting power source to the SR-750 Series.

• Connect the power supply wire of the control cable to a 24 V DC power supply device.

• Connect to a PoE (Power over Ethernet) power supply device using the Ethernet port.

Use only one of the above methods to connect to the power source according to the usage.

Make sure to use either one of the connection methods for power supply.

NOTICE

If power is supplied both from the control cable and PoE power supply device at the same time, the unit may be damaged.

Wiring when supplying 24 V to the control cable

• Use a steady power supply voltage of 24 V DC ±10%.

• Do not use a power supply other than 24 V DC. Otherwise, it may cause failure.

• Before connecting or disconnecting cables, make sure to turn off power to the equipment connected to the SR-750 Series. Otherwise, it may cause the failure of the SR-750 Series.

Connection when supplying power from a PoE device

Use the Ethernet cable for the SR-750 Series for connection. Connect the RJ-45 connector of the Ethernet cable to a device (switching hub, etc.) compatible with the PoE power supply feature.

Cable and Wiring

Connect the control cable to the SR-750 Series.

Control cable connection method

1 Align the dent of the cable connector with the marking position next

to the control port.

POWER

2 Tighten the connector screw by turning clockwise. Set the screw

tightening torque to 1.5 - 2.0 N•m.

When connecting the connector, insert it not to lean toward one side and securely tighten it. Under-tightening can lead to loose connector due to vibrations, resulting in poor contact. Insufficient tightening may not meet the requirements of the protective structure. * To get a rough idea, after tightening it by hand, retighten it

approximately 90° - 120° using a tool such as pliers. Do not repeatedly bend the root of the connector of control cable. Loose connection may result.

Control cable color and the meaning of signal

Be sure to connect with a PoE power supply device compliant

3-3 Alternate Function

This section describes the alternate function.

Alternate Function

The SR-750 Series can perform the reading operation while switching between multiple parameter banks that are registered for the code being read. The function that performs reading operation with the most appropriate parameter while automatically switching the parameter bank - this is called "Alternate Function". Even when there are fluctuations in printing conditions or reading distance, since it operates by switching between multiple parameter banks during a single read operation, a stable read operation is provided. By default, read operation is performed using the parameter bank 0 (bank for read quick setup code).

Parameter banks

The SR-750 Series sets parameters necessary for code recognition such as scan conditions and filter conditions. Location where this setting is stored is called a "Parameter Bank". The SR-750 Series has 10 parameter banks. Multiple optimal parameters can be registered according to work conditions and printing conditions.

The following settings are stored in the parameter bank.

• Code type............................Set the version of the code to be read, the number of

codes, and the output length limitation function.

• Internal light/External light... Set whether or not to use internal lighting and external lighting.

• Scan conditions................... Set exposure time, gain, and dynamic range.

• Filter .................................... Set the filter condition to be used.

• Others ................................. Set the alternate, decoding area, algorithm, etc.

4 Click [Calibration] button.

The most appropriate scan condition is automatically set according to the code. Settings are registered with bank, and the operation finishes.

5 Perform the reading test.

Perform the reading rate test and processing time test, and confirm the reading stability of the calibration result.

• Reading rate test display screen • Processing time test display screen

Alternate Function Operations

The following flow chart illustrates operations that occur during the alternate function:

* Reading starts from the bank set as the "Alternate start bank".

Important

Since the alternate function cycles through the parameter banks one at a to determine the optimal settings, overall processing time may increase. (The processing time depends on the decode timeout period setting.) The alternate function is turned off by default. The function is enabled automatically after the Tuning operation has been performed on any of the parameter banks. The alternate function is disabled in the following cases:

• When using the read mode in the burst mode

• When the alternate function is turned off for all parameter banks

• When the bank specify trigger input command (LON01 to 10) is sent to directly specify the parameter bank for reading.

When the alternate setting order is set to "Begin with successful bank", the next reading starts from the parameter bank of the most recent successful reading. When codes with similar conditions are read in sequence, prioritizing according to the last successful bank may result in a shorter reading processing time.

Operation of the bank prioritizing function when parameter banks 1 to 4 are used

The reading order is changed to start reading from the parameter bank of the previous successful reading.

The bank prioritizing function is effective only in Operation mode. The reading order is reset to the default setting when one of the following operations is performed:

• Stopping the power supply

• Entering the test mode

• Entering Setting mode or Test mode

• Changing the alternate setting

 Online mode

Online mode is useful for troubleshooting issues during run-time operation. Online test mode can only be enabled through serial command input.

Test Mode Details

This section describes the advanced details of each test mode.

Reading rate test mode

This test mode scans codes and measures the number of successful reads. The offline mode scans 10 times and outputs the number of successful reads. The offline test mode outputs the reading rate which is obtained from the number of decodes against the number of decodes attempted while the trigger input is ON.

The parameter bank switches while scanning, just as when reading with the alternate function. When reading is successful, the parameter bank used for reading is fixed and the reading rate is calculated. When a read error occurs, the test mode switches to another parameter bank and continues the measurement.

Online and offline modes

 Offline mode

Offline mode is useful for fine-tuning the installation position, distance or angle during initial setup. Data is continuously output as long as the test is active. The test result data is output in real time.

Function

This section describes the preset/verification function.

Preset/Verification Function

This function allows the SR-750 Series to verify the read code data against the registered code data (preset data), and output an OK/NG signal to indicate whether or not they match. This allows the SR-750 Series to perform simple detection of different codes without a sensor or other devices. One set of preset data can be stored in the SR-750 Series (maximum 494 digits). The starting digit (starting position) and range (number of digits) for the verification can be set in the preset data, so even codes with more than 494 digits can be verified. * If the multi 2 read mode or multiple read mode is set, the preset verification

function cannot be used.

The verification starts at the specified starting position on the preset data and continues for the specified number of digits. Data cannot be verified at multiple points.

Registering preset data

Use one of the following procedures to register preset data with the SR-750 Series:

• Read a target code by turning on the external input terminal. * You need to assign the preset data input function to the external input terminal

in advance.

"3-6 Multi-I/O Function (Page 14)"

• Set with the AutoID Network Navigator "5-4 Details of Settings View (Page

34)"

• Set with a setup command "8-3 Details of Configuration Commands (Page

75)"

 Output data format for the preset registration result

The following output data format is used when the preset data is registered.

PR nn : Result data nn = Preset registration result (00 to 05)

Sequence Verification Function

This function allows verification of codes including numerical values which change in series, such as workpiece serial numbers. When the verification is OK, a value is added to/subtracted from the preset value. When the verification is NG, neither addition nor subtraction is performed. When the sequence verification is set, the first data read after the setup or poweron is used as the preset data, and the numerical data for the number of digits set is verified. When the PRESET input terminal is turned on during the automatic increment verification, the current preset value is cleared, and the data to be loaded next is used as the first load data.

The sequence verification requires the following settings:

• Verification method .........Select "Sequential".

• Starting digit ....................Set the number of digits where the value verification

starts.

• No. of digits ("Length") .... For the numerical verification, the acceptable number

of digits is 1 to 9 digits.

• Increment ........................Enter a value used to add to or subtract from the read

code value. (-9999 to 9999)

The following is the operation example when the starting digit is the third one, two digits are referenced and an increment of +2 is specified:

The following restrictions are placed on the sequence verification function:

• The verification results in NG when a value other than a numerical value is read.

• The preset data cannot be registered through communication.

nn Description Result data

00 Preset registration success Read data

01 Preset read failure Read error data

02 The preset effective digit is specified as 0.

The number of digits of read data is less

than the number of digits for preset start.

The preset registration is not possible

because the operation mode is set to multi 2 or multiple read.

05 Two or more "!" exist in preset data.

[null]

Output terminal operation

The output terminals perform the following operation:

• Reading successful and matches preset data ............. OK is output

• Reading successful but does not match preset data ... NG is output

• Read error .................................................................... ERROR is output

• Preset data is registered successfully.......................... PRESET OK is output

By default, the PRESET OK output is not assigned to any of the OUT1 to OUT3 terminals. To connect the PRESET OK output to an

NOTICE

external device, assign the PRESET OK output to an appropriate OUT terminal.

Functions of "!" and "?" in the preset data (wild cards)

Registering "!" or "?" with the preset data increases the flexibility when comparing and verifying the code data against the preset data.

"!" .......This character represents an unlimited number of digits and can be used

when any character for any number of digits is OK. If the preset data is "A B C!", all codes that begin with "ABC" are verified as a match. If the preset data is "!ABC", all codes that end with "ABC" are verified as a match. A maximum of 1 "!" can be registered with the preset data.

"?" ......This character represents 1 digit and can be used when any one character

is OK. If the preset data is "A B??5 6", any 2 characters positioned in ?? are verified as a match. If the preset data has not been registered, "!" is registered instead. Consequently, OK is output when a barcode is read successfully and ERROR is output when reading fails, regardless of the data of the bar code.

By default, the PRESET output is not assigned to any of the OUT1 to OUT4 terminals. To connect the PRESET OK output to an external device, you need to assign the PRESET OK output to an appropriate

OUT terminal.

3-6 Multi-I/O Function

You can assign various operating conditions to the I/O terminals of the SR-750 Series. This section describes operations available with the Multi-I/O function.

Function and Operation of the Input Terminals (IN1 and IN2)

Functions assigned to the input terminals

Only 1 of the following functions can be assigned to each of the input terminals IN1 and IN2:

• Trigger input: Use as the input terminal to start/stop reading codes.

• Preset data input: Use as the input terminal to register preset data.

• Start test mode: Use as an input terminal to activate the specified test mode. (This function cannot be used to start the online test mode.)

• Clear PLC link error: Use as the terminal to clear the PLC link error.

• Tuning operation: Use the terminal to activate the quick calibration function.

• None: Select this option when the terminal is not used as an input terminal.

Use AutoID Network Navigator or setup command to change the setting or assign the desired function.

* By default, the functions are assigned as follows:

IN1: Trigger input IN2: Preset input

Tuning operation (TUNING) Start quick calibration Quit quick calibration

ON OFF

 Synchronous IN LED

Users can set the SR-750 Series to illuminate its IN LED when the IN1 or IN2 terminal turns on. When both IN1 and IN2 terminals synchronize with the IN LED, the LED illuminates based on the OR condition of the terminal status. (By default, only the IN1 terminal synchronizes with the LED.)

 Input polarity setting

The polarity of the input terminal can be selected from "N.O. (normally open) contact" or "N.C. (normally closed) contact". (By default, "N.O. contact" is selected.) The same input polarity is set for IN1 and IN2.

 Power-on trigger setting

Normally, the input terminal recognizes the change in the input signal (ON/OFF) after the SR-750 Series is turned on and its operation stabilizes. The input terminal does not operate if the input signal turns on before the operation stabilizes (approximately 500 ms after power on). If "Power-on trigger" is enabled, the SR-750 Series recognizes the input ON status during the start-up period, and after the operation stabilizes, it performs the operation specified for the input signal. (By default, "Power-on trigger" is disabled.)

Function and Operation of the Output Terminals (OUT1, OUT2 and OUT3)

Functions assigned to the output terminals

The following functions can be assigned to the output terminals (OUT1 to OUT3). You can assign one or more functions to each output terminal.

 Result output

This function outputs judgment results according to the SR-750 Series operation.

• OK .................... This signal is output when a bar code is read successfully or

when the comparison/verification against preset data matches.

• NG.................... This signal is output when the comparison/verification against

the preset data does not match.

• ERROR ............ This signal is output when a read error occurs.

• STABLE............ This signal is output when reading is stable ("Matching level

assessment function" or "Code quality verification function" is enabled and the matching level or Code quality verification result exceeds the set threshold).

• UNSTABLE ...... This signal is output when reading is unstable ("Matching level

assessment function" or "Code quality verification function" is enabled and the matching level or Code quality verification result falls below the set threshold).

• PRESET OK .... This signal is output when the preset data is registered

successfully.

• TUNING OK ..... This signal is output when the calibration is complete.

 Operation output

This output function notifies that the SR-750 Series is currently running.

• TRG BUSY.......... During the start-up period, trigger input, preset data

registration, calibration, test mode, or while images are being sent to FTP, bank numbers are being displayed, live view data are being sent, monitoring is being performed, while the laser pointer is on, images are being saved to ROM, the quick setup codes are being read or being scripted

• LOCK BUSY ....... Forced trigger lock is being applied.

• MODE BUSY....... The quick setup code is being read, during test mode

• ERR BUSY.......... Error occurred (buffer full, setting save error)

 External light control output

• EXT. LIGHT......... This signal is output to control external illumination.

• The result outputs (OK, NG, ERROR, STABLE, UNSTABLE, PRESET OK, TUNING OK) and the outputs in operation (TRG BUSY, LOCK BUSY, MODEBUSY, ERR BUSY) and EXT.LIGHT cannot be set for the same terminal.

• EXT.LIGHT can be assigned to OUT3 only. Also, when EXT.LIGHT is assigned to OUT3, no other output can be assigned to OUT3.

• Power-on trigger setting

 Required input duration setting

Users can set the "Required input duration", which is the period required for the ON status of the input terminal to be recognized. The function assigned to the input terminal is activated after the input stays on for specified time or longer. (Required input duration setting range: Selectable from 1 ms, 2 ms or 10 ms; default setting is 1 ms.)

Output terminal operation

The output terminals operate differently depending on the assigned function. There are three types of operations as shown below:

 OK, NG, ERROR, STABLE, UNSTABLE, PRESET OK, and

TUNING OK output

The above signals turn on the output for the specified output ON time when the respective event occurs.

* For the above output functions, a higher priority is assigned to the output of the

function which occurred last.

Consequently, when the next operation occurs during the output ON time of the previous operation, the signal is switched to output the signal of the higher priority function.

3-7 Image Saving Function

This section describes the image saving function of the SR-750 Series.

Image Saving Function

The image saving function is used to save the scan image into RAM/ROM of the SR-750 Series based on the image saving mode settings or to send to PC via FTP communication. Saved images can be used for analyzing causes of read error, etc.

• AutoID Network Navigator setting screen

Type of images to be saved

 TRG BUSY, LOCK BUSY, MODE BUSY and ERR BUSY

output

The above signals are retained until the corresponding event ends. (The period is not affected by the period of time set for the output ON time.)

* If multiple BUSY outputs are assigned to one output terminal, the output signal is

turned off when all events finish.

 EXT.LIGHT (external illumination) output

The above signal is output in synchronization with the scan timing. The output polarity can be selected from "N.O. (normally open) contact" or "N.C. (normally closed) contact". The timing diagram shows the operation for the N.O. contact:

• EXT. LIGHT can be assigned to OUT3 only.

• When EXT. LIGHT is assigned to OUT3, no other output can be assigned to OUT3.

 Latest image

The SR-750 Series stores a scanned image to RAM temporarily and performs decoding process for the image data. The image before decoding process is called the "Latest image".

• The "Latest image" saves up to 10 images to RAM in one time reading operation.

• The type of image of the "Latest image" is set to "L" for the file name.

• To confirm the "Latest image", use the image view function and file view function of the AutoID Network Navigator.

Refer to "5-10 ImageView (Page 52)""5-11 FileView (Page 53)"

 Judged image

An Image for which decoding process is performed and the read result is judged is called "Judged image". The "Judged image" can be set for each judged result.

• Read OK, Verification NG, Unstable image

: Not save or FTP transmission

• Read error : Not save, RAM save, ROM save or FTP

transmission

The "Judged image" is saved according to the following rules.

•

The number of judged images to be saved varies according to the reading operation and image saving mode. (Max. 10)

•

The type of image for the file name of the "Judged image" is set as follows according to the judged result.

Reading success : S Reading error : E Verification NG : N Unstable image : W

: X....... The image was scanned in the burst read mode,

but the decoding process was not performed.

• To confirm the "Judged image" saved into RAM/ROM, use the image view function and file view function of the AutoID Network Navigator.

Refer to "5-10 ImageView (Page 52)""5-11 FileView (Page 53)"

 Capture image

This is an image scanned using the capture function of the SR-750 Series. One image is saved with one-time capture operation. You can select either RAM or FTP transmission as the save destination for capture images.

• Capture operation can be performed using the image view function or operation command.

• The type of image is set to "C" for the file name of the "Capture image".

• To confirm the "Capture image" saved into RAM, use the image view function and file view function of the AutoID Network Navigator.

Image save mode

The following 3 image save modes are available:

• Save final bank image

• Save images after timing input ON

• Save images of the specified number before trigger input OFF This section describes each mode.

 Read OK/Comparison NG (When the preset/comparison

function is used)/Unstable image

(1) When the reading mode is the single read mode or multi 1 read mode

Only successfully read images of both the latest images and judged images are saved. (This is the example of when the parameter banks 1 to 3 are used.)

(2) When the reading mode is the multi 2 read mode

Judged images and parameter bank images successfully read are all saved. For the latest images, only the image obtained last is saved. (This is the example of when the parameter banks 1 to 3 are used.)

(3) When the reading mode is the burst read mode

For the latest images, all burst scanned images are saved. For the judged images, only the images that can be decoded are saved. (This is the example of when the burst execution bank is 1 and the number of burst scans is 5.)

Save the latest bank image

In this mode, the SR-750 Series performs reading operation and saves the image at the timing when the read result is judged. Depending on the reading mode of the SR-750 Series, saved images and the determination timing for images to be saved are as follows. Refer to "4-4 Read Mode (Page 28)"

 Read error

(1) When the reading mode is the single read mode or multi 1 read mode

When a reading error occurs, all parameter bank images used for reading operation are saved one by one as judged images. For the latest images, only the image obtained last is saved.

TRG BUSY output

In the multi 2 read mode, if reading judgments (Success or Failed) differ among parameter banks, the judged images of parameter banks that were judged as reading error are saved. For the latest images, the image obtained last is saved.

Save images of the specified number before trigger input OFF

When the read result is judged or the trigger input turns OFF, the SR-750 Series saves images of the specified number before then.

 Image saving timing

The timing when images to be saved are determined is the same as the timing when Read OK/Verification NG is determined, or the trigger input turns OFF and Read error is determined. The number of images to be saved can be specified by using AutoID Network Navigator or setting commands for both the latest images and judged images. (Max. 10 for each)

(3) When the reading mode is the burst read mode

If a read error occurs in the burst read mode, the judged images for the save target burst numbers are only saved. For the latest images, all burst scanned images are saved.

If the trigger input turns off before the decoding process for scanned images are not complete, the judged images as save targets are saved with the type of image "X" (Decoding process not performed).

NOTICE

Save images of the specified number after trigger input ON

When the read result is judged, the SR-750 Series saves images of the specified number after the reading operation began.

 Image saving timing

The timing when images to be saved are determined is the same as the timing when Read OK/Verification NG/Read error is judged. The number of images to be saved can be specified by using AutoID Network Navigator or setting commands for both the latest images and judged images. (Max. 10 for each)

·····

• Image number is counted in the obtained order as 1, 2, 3···.

• When the reading mode is the multi 1 read mode, image saving is impossible with this operation.

• When the reading result can be judged before reaching the specified number, the images until that point are saved.

• When the reading mode is the burst read mode, up to 8 images are saved. In the burst read mode, the SR-750 Series saves images of the specified number (burst scan count) for both the latest images and judged images.

3-8 Silent Mode

This section describes the silent mode of the SR-750 Series.

Silent mode

A typical code reader outputs data of the result when the code is read or the read error code when it is not read. The SR-750 Series can be configured to restrain data communication and not to output the result data to the host computer. This function is called "Silent mode". For example, if the application only uses the OK, NG or Read Error terminal outputs, this information can be suppressed. By configuring the SR-750 Series not to send all data, it eliminates the time required for data transmission to/from the host computer. As a result, overall reading time can be reduced.

 Timing diagram (when OK/NG/ERROR data is restrained)

NOTICE

E SR-750 UM

·····

• When the reading mode is the multi 1 read mode, image saving is impossible with this operation.

• When the reading result can be judged before reaching the specified number, the images until that point are saved.

Only data is not sent as shown above, but the OUT output terminal performs normal operation. * Even with the silent mode set, images can be saved with the condition set using

the image save function. Refer to "3-7 Image Saving Function (Page 16)"

Users can print the settings specified with AutoID Network Navigator as 2D code and read the code with the SR-750 Series to change all the settings at once. When printing the quick setup code, use the AutoID Network Navigator quick setup code printing function. Since the settings of the SR-750 Series can be changed by reading the quick setup code, you can easily change the settings even in a location where a computer cannot be used.

 Print image

 Sending the quick setup code reading commands

Send the quick setup code reading command (RCON) to read the quick setup code.

1 Send the "RCON" command from the control device.

When the SR-750 Series receives the command normally, it returns "OK, RCON", and "C" and "0" are displayed alternately on the multiple LED indicator of the SR-750 main unit.

2 Read the quick setup code.

According to the code reading status, values displayed on the multiple LED indicator of the SR-750 main unit change.

3 When all quick setup codes are read, "d" is displayed on the multiple

LED indicator of the SR-750 main unit.

4 Send the "RCOFF" command from the control device.

When the SR-750 Series receives the command normally, it returns "OK, RCOFF", and the quick setup code reading operation finishes. (After the setting is reflected, "d" on the multiple LED goes off.)

• While reading the quick setup code, the TRG BUSY and MODE BUSY outputs turn ON.

• To cancel the quick setup code reading operation, send the "RCOFF" command.

When reading the quick setup code with the high-resolution type unit (SR-750HA), you must use a printer with high print quality. When a printer with low print quality is used, the cells in the 2D code may bleed and become unreadable.

Setting method for the Code quality verification function

To use the Code quality verification function, you need to enable the verification settings you wish to use. (1) Setting using the AutoID Network Navigator.

Press the "Code quality verification" button on the "Operation" tab in the Settings view, and then check the desired verification standard.

(2) Setting using the setup commands

Send commands that enable the verification functions you wish to use.

"8-3 Details of Configuration Commands - Reading operation setting (Page 77)"

When the Code quality verification function is enabled, the decode time becomes longer than when it is disabled. Perform calibration after enabling the Code quality verification function or set the decode timeout period required for reading. Use the tact measurement test mode to confirm there is no problem with reading time for operation. ( "3-4 Test Mode" (Page 12))

Append Code quality verification result data

To append the Code quality verification result data, the additional data setting and data format setting are required.

 Additional data setting

Select "Operation" - "Additional data" on the "Table" tab in the Settings view, and then set verification results you wish to append as data to "Enable".

"5-4 Details of Settings View - [Table] tab (Page 43 or later)" "3-11 Code quality verification function - Verification items description (Page 21

or later)"

 Data format setting

Make the setting relating to the data format. Set the following three items.

• Select expression of grades : Set the grade indication of the verification result to either Alphabet or Numeric. (ISO/IEC15415 and ISO/IEC TR 29158 (AIM DPM-1-2006) only)

• Append detailed verification result : Set whether to append verification items of each standard to the total grade. (ISO/IEC15415, ISO/IEC TR 29158 (AIM DPM-1-2006) and SAE AS9132 only)

• Append values : Set whether to append evaluation values of each verification item used for verification result evaluation. (ISO/IEC15415, ISO/IEC TR 29158 (AIM DPM-1-2006) and SAE AS9132 only)

"7-2 Data Communication Format (Page 63)"

Code quality verification function Evaluation standard

Evaluation by the Code quality verification function is made for the total evaluation grade. Evaluation standards are as follows.

 ISO/IEC15415, ISO/IEC TR 29158 (AIM DPM-1-2006)

High: Verification result >= Threshold value Low: Verification result < Threshold value

 SAE AS9132

High: Verification result = Pass Low: Verification result = Fail

Important

SEMI T10-0701 does not offer total evaluation grade and cannot make evaluations. This means that functions that can be used after evaluation cannot be used with SEMI T10-0701.

Functions that can use evaluation results of the Code quality verification function

 STABLE terminal output, UNSTABLE terminal output

STABLE terminal output......... This is output when the total evaluation grade is the

UNSTABLE terminal output ... This is output when the total evaluation grade is less

( "3-6 Multi-I/O Function (Page 14)")

threshold value or more.

than the threshold value.

 Saving images of unstable reading

When the total evaluation grade is less than the threshold value, scanned images are saved according to the setting (If the FTP transmission is set, images are sent to the connection destination.). ( "3-7 Image Saving Function (Page 16)")

 Silent mode

When the total evaluation grade is more or less than the threshold value, data communication can be restrained using the silent mode. ( "3-8 Silent Mode (Page 18)")

Point

When multiple verifications are in process, these functions operate in priority to the result which is less than the threshold value.

Note when using the Code quality verification function

Code quality verification results may change according to the setting of the parameter bank for scanning. If the color or contrast of the 2D code and background change, consider preparing the parameter bank setting used as standard and performing the Code quality verification using the setting.

Duplicate reading prevention interval reset

The duplicate read prevention function is equipped with the Multi1 reading mode not to read codes again that have been read once. The working time of this duplicate reading prevention function is set by the duplicate reading prevention interval. Two types of the duplicate reading prevention interval reset operation have been prepared with the SR-750 Series.

Types of the duplicate reading prevention interval reset

Two types of the duplicate reading prevention interval reset

• Reset when a code is read.

• Do not reset during duplicate reading prevention interval.

This section describes each operation.

Reset when a code is read.

The duplicate reading prevention function works for one data most recently read. If different codes are read, the duplicate reading prevention interval is reset and the duplicate reading prevention function works for the newly read code data. The duplicate reading prevention interval count starts at the timing when the last code is read.

 Timing chart

(1) (1) (2) (1) (2) (2)

Duplicate reading

(1) (2) (1) (2) (2)

• When reading is successful, reading continues using the successful bank until a reading error occurs.

• If codes with the same contents are read in series, adjust the passing time longer than the time set with the duplicate reading prevention interval (setting range: 100 to 25500 ms). Codes with different contents can be read in series.

• The timing to start measuring the duplicate reading prevention interval is when the code that was read is outside the field of vision.

Do not reset during duplicate reading prevention interval.

The duplicate reading prevention function works for all codes read within the set duplicate reading prevention interval from when the timing input was done and the first code is read. The duplicate reading prevention function works again when the next code is read after the duplicate reading prevention interval finishes.

 Timing chart

Important

If multiple codes in the same type are seen in the field of view at the same time, take one of the following methods.

• Prepare multiple parameter banks with the read length restricted, and make the setting so the parameter banks are switched for each code.

• Prepare multiple parameter banks with the decoding area restricted, and make the setting so the parameter banks are switched for each code.

* When Multi read (setting within 1 parameter bank) is set to

Enable, if the code data that was read once matches with any of the multiple read code data in 1 scan, not all code data read in the scan are not output.

Edit data function/Edit image file name function

With the edit data function, read data can be edited into a desired data format. With the edit image file name function, when sending image files to upper ranks via FTP, the image file names can be edited into desired file names.

The edit data function and edit image file name function can do the following.

 Edit data (Basic)

• Four arithmetic operations (add, subtract, multiply and divide)

• Conditional branching

• Adding arbitrary characters

• Extracting and combining arbitrary digits

 Edit data (Advanced)

Various types of data can be built using four arithmetic operations, conditional branching, etc. from appended data information, etc. [Example]

• Code rotation angle (Calculated from top coordinates)

 Edit image file name

• Time stamp*

• Append read data

Important

• The edit image file name function is available only for images sent via FTP. This does not function for images saved in RAM and ROM.

• This does not support quick setup codes.

* When using the time stamp, enable the SNTP function of SR-750

and connect to the SNTP server. (For SNTP setting items, refer to Page 48.)

Procedure for setting the edit data function and edit image file name function

The edit data function and the edit image file name function can be used by sending the file which contains the program of Script to SR-750 and enabling the "Use script file" setting.

This section describes the reading conditions of the SR-750 Series.

Steps of Read Operation

The SR-750 Series follow the read sequence below:

(1) Trigger input processing : Trigger input is verified and light is

controlled.

(2) Scanning + image transfer : The image is scanned within the specified

exposure time and the image is transferred.

(3) Decoding processing : The captured image is filtered and the code

is processed (decoded).

(4) Data communication processing : The decoded results are output as data.

Internal bank retry count

When the internal bank retry count is set, 1 parameter bank is repeated. When decoding cannot be complete within the specified internal bank retry count, operation to switch to the next parameter bank is possible. If reading operation becomes unstable due to vibration of the workpiece, setting the internal bank retry count enables stable reading.

 Timing Chart

Since (2) and (3) above are based on the settings registered with the parameter banks, operation is repeated using alternate banks until a code is read or the trigger input is turned off.

Specify the following operations for the above processing:

• Timing Mode Specify from level trigger or one-shot trigger.

• Data Transmission Select "Send after read" or "Send after timing OFF".

• Read mode Specify from Single, Multi1, Multi 2 or burst.

Timing Chart

This section describes the steps of basic operations of the SR-750 Series. Operating conditions are as follows:

• Timing Mode : Level trigger

• Timing to send data : Send after read

• Read mode : Single

• Parameter bank : Set 2 banks, alternate mode

A: Input time constant + Scan delay time B: Exposure time set for each parameter bank (max. 9.99 ms) C: Image transfer time (approx. 16 ms) D: Decode time out period set for each parameter bank (Max. 2550 ms) F: Decoding time when reading is successful

• The above is the image when reading is successful. For read error, B, C and D are repeated continuously and read error data is output when the trigger input is turned off.

Scan delay time

• The internal bank retry count can be set within the range from 0 to 32. (Factory setting: 0)

• If a large number is set for the internal bank retry count and multiple parameter banks are registered, reading time per time will become longer. Secure sufficient reading time so that reading can be stable.

4-2 Timing Mode

This section describes the timing mode of the SR-750 Series.

Type of timing mode

The SR-750 Series provides the following 2 types of timing mode.

• Level trigger

• One-shot trigger

For the remainder of this section, assume the following settings are used:

• Read mode : Single

• Data Transmission : Send after read

• Output terminal settings OUT1 = OK

OUT2 = NG + ERROR

OUT3 = TRG BUSY * Output terminal settings "3-6 Multi-I/O Function (Page 14)" * For convenience sake, the timing chart does not indicate the input pulse width +

scan delay time.

Level trigger

When the trigger input turns on, the SR-750 Series turns on the illumination to start scanning. When a code is read successfully, it stops illumination and sends the data. If the SR-750 Series fails to read a code, it stops illumination when the trigger input turns off and sends a reading error.

 Timing Chart

When the entry timing of the target to be conveyed is shifted from the input timing of the timing sensor, set the "scan delay time". This makes it possible to start scanning under optimum read conditions by setting the delay for the timing at which emission of light of the SR-750 begins.

• The time can be set between 0 and 255 ms in increments of 1 ms (Default: 0 ms).

• Set the scan delay period for the parameter bank.

E SR-750 UM

OK/NG ERROR

• Set the trigger input so it stays ON from the reading start time until reading end

time.

• The illumination of the SR-750 Series turns on after the trigger input has been

activated for the specified input time constant.

• The input time constant for the trigger input can be changed to 1 ms, 2 ms, or 10

ms.

• The RS-232C data communication time can be obtained using the following

equation:

Data communication time= × (Number of digits of data to be sent +

Number of characters of header and terminator)

• The ON time for the OK/NG/ERROR output can be set within the range of 10 to

2550 ms (Default: 500 ms).

Refer to "Page 15 Function and Operation of the Output Terminals (OUT1, OUT2 and OUT3)".

The TRG BUSY output turns on from the time the trigger input turns on to the time the code reading is complete or the trigger input is turned off.

One-shot trigger

When the SR-750 Series detects that the trigger input is on, it turns on the lighting for the specified one-shot trigger duration to scan a code. When a code is read successfully, it stops illumination and sends the data. Other operations are the same as those for the level trigger. Use the one-shot trigger if the ON time of the trigger input is extremely short or if you want to fix the read time.

 Timing Chart

4-3 Data Transmission Timing

This section describes the data transmission timing of the SR-750 Series.

Type of data transmission timing

The SR-750 Series offers the following 2 options for outputting the read data and OK/NG/ERROR signals:

• Send after reading

• Send after timing OFF Select the appropriate type for your application. * For the sake of simplicity, Input time constant + Scan delay time is not shown in

the timing chart.

Send after reading

The SR-750 Series outputs read data and an OK/NG signal as soon as it completes reading codes. If the SR-750 Series fails to read a code, it outputs a read error code and an ERROR signal at the point when the timing signal turns off. The timing charts are the same as those shown in "Timing Mode".

"4-2 Timing Mode (Page 26)"

Send after timing OFF

When "Send after timing OFF" is selected, the SR-750 Series outputs read data and an OK/NG/ERROR signal at the next timing point for the specified trigger type. Use this type to output data and output signals with the same timing.

 Timing Chart for the level trigger

When the trigger input turns off, read data and OK/NG/ERROR signal are output.

• When the trigger input stays on for the specified input time constant, the illumination of the SR-750 Series turns on and the scanning begins. When the reading is complete, the illumination stops.

• The input time constant for the trigger input can be changed to 1 ms, 2 ms, or 10 ms.

• The one-shot trigger duration can be changed within the range of 100 to 25500 ms.

• If the SR-750 Series fails to read a code within the one-shot trigger duration, it stops illumination and outputs a reading error.

• Other operations and precautions are the same as those for the level trigger.

The ON state of the trigger input is recognized after the input stays on for at least the specified input time constant. The OFF state of the trigger input is recognized after the input stays off for at least the specified input time constant. Consequently, when the line speed is fast and fast pulse signals are used as trigger input signals, be careful to make the ON/OFF time of the pulse signals longer than the specified input time constant.

Trigger input time constant = when a, if a becomes larger than b, the OFF state of the trigger input is not recognized. When a ≤ b, the ON/OFF state of the timing signal can be recognized.

OK/NG ERROR

• When a code is read successfully, the read operation stops.

• The TRG BUSY output continues until the trigger input turns off.

 Timing Chart for the one-shot trigger

When the specified one-shot trigger duration elapses, the read data and OK/NG/ ERROR signal are output.

OK/NG ERROR

• When a code is read successfully, the read operation stops.

• The TRG BUSY output continues until the one-shot trigger duration elapses.

Duplicate reading prevention interval

The SR-750 Series offers 4 types of read modes. Select the appropriate type for your application. For most applications, use "Single read mode". * For the sake of simplicity, Input time constant + Scan delay time is not shown in

the timing chart.

Single read mode

In this mode, the SR-750 Series reads a single code while the trigger input is turned on once, and then outputs data. Scanning will not begin again until the timing input is first turned off, then back on again.

 Timing Chart

* The above timing chart shows the case where "Level trigger" and "Send after

reading" are selected.

• In single read mode, the data transmission timing can be selected from "Send after reading" or "Send after timing off".

• The timing mode can be selected from "Level trigger" or "One-shot trigger".

• Scan interval is automatically set so that decoding processing can be implemented efficiently.

"4-1 Reading Operations (Page 26)"

Multiple Code Reading in Single Read Mode

Normally, the single read mode is used to read 1 code from 1 timing input signal. When the following read setting conditions are specified, multiple codes within the field of view can be read with 1 timing input signal.

 Setting "Multi read" in the code detail settings

When "Multi read" is selected in the code detail settings, multiple codes can be read in 1 reading operation.

• Use the AutoID Network Navigator or setting command to set.

• The number of codes for multiple readings can be set between 2 and 16

• When "Allow reduced detection count" is selected, the reading is considered successful if at least 1 code is read successfully.

Multi 1 Read Mode

In this mode, the SR-750 Series reads multiple codes in succession while the trigger input is turned on once. In Multi 1 read mode, the SR-750 Series sends out data and outputs an OK signal every time it reads 1 code (or an OK/NG signal when preset data is registered). The SR-750 continues to scan while the trigger input is on even if no code is present. ERROR will only be output if no code is read after the trigger signal is turned off.

 Timing Chart

• The SR-750 Series reads codes in succession for the following duration: Level trigger : While the trigger input is turned on One-shot trigger : During the specified one-shot trigger duration

• The duplicate reading prevention operation changes according to the setting of the duplicate reading prevention interval reset. "3-12 Duplicate reading prevention interval reset" (Page 24)

• When codes with the same contents are read in succession, adjust the moving speed so that the codes pass at intervals longer than the specified duplicate reading prevention interval (Setting range: 0 to 25500 ms). Codes with different contents can be read at shorter intervals.

• Each time scanning is performed in Multi 1 operation, the laser pointer lights up. The lighting period for the laser pointer is set on "Laser-aimer blinking duration (0 to 990 ms)" and the scanning is not performed during this period.

• The data transmission timing for Multi 1 is "Send after read" only.

• In Multi 1 operation, the availability of the image save function is as follows. Saving images

• Read OK/NG ...Cannot be used

• Error image .....Can be used

Point

When Multi 1 read mode is selected using the AutoID Network Navigator, the decode timeout is set to 500 ms. To shorten the decode timeout period, change the decode timeout setting of each parameter bank manually.

• In this setting, multiple codes of different types cannot be read in 1 read action.

• Codes are output in order starting from the code coordinates above the upper scan screen (if the height is the same, from the left).

• The output data format is as follows:

Multi 2 read mode is used to read the codes in the parameter banks with registered settings in order while the trigger input is turned on once. After reading all codes (max. 10 types) registered with the parameter bank, this function sends the read data in the order of parameter number and outputs OK/NG signals. If no code is read while the trigger input is turned on or if even one code set for a parameter bank is not read, the SR-750 Series sends a reading error and outputs an ERROR signal for the unread code in the parameter bank after the trigger input turns off.

 Timing Chart

Timing charts when registered with the parameter banks 1, 2 and 4 are as follows:

Burst Reading Mode

The burst reading mode is a function to repeat scan up to a maximum of 8 times in succession and perform decoding after the scanning is complete. When, for example, the line speed is fast and accurate positioning is difficult, this function ensures scanning without missing codes by repeating scans only for the period during which the target is expected to pass.

Point

• The alternate function cannot be used in Burst reading mode. Decoding is performed with the specified parameter number.

• In Burst reading mode, the No. of repeat read attempts setting is ignored.

 Timing Chart

The following is the timing chart when the Burst reading mode is used. (Burst scan count: 3)

No. of burst scans

• The SR-750 Series reads codes in succession for the following duration: Level trigger : While the trigger input is turned on One-shot trigger : During the specified one-shot trigger duration

• An OK signal is output when all of the codes of the set parameter banks are read.

• An ERROR signal is output when even 1 specified code could not be read.

• Even when there are multiple codes within the reading range, all codes can be read simultaneously.

• Each time scanning is performed in Multi 2 operation, the laser pointer lights up. The lighting period for the laser pointer is set on "Laser-Aim pulse duration (0 to 990 ms)" and the scanning is not performed during this period.

 Output data format

The following output data format is used for the read data.

• Each read data is separated with "," (0x2C: Intermediate delimiter).

• The data for the read bar codes is saved in the send buffer of the SR-750 Series once and then is output when all configured banks have been read or the timing input is turned off. The size of the send buffer of the SR-750 Series is 10 KB.

• If reading fails for any of parameter banks 1 to 10 or if the specified code is not found, ERROR is sent as the read data of the corresponding parameter bank number.

• In Burst reading mode, the scanned data is decoded in the order in which it was obtained. If decoding fails after the decode timeout period elapses, the decoding is shifted to the next scanned data.

• The data communication is output when the decoding is successful or decoding of all scan data is failed. The decoding time when decoding succeeds for the third scanned data is as follows:

• If the trigger input turns off with the decoding processing unfinished, reading error occurs. Secure longer time for the trigger input ON than the time calculated by (scan + burst scan interval + decoding timeout time) x burst scan count.

• The data transmission timing for the Burst reading mode is "Send after read" only.
