Warnings and Cautions Specific to the BL-700

• The BL-700 uses a 5 VDC power supply. Using a different voltage level may damage the unit. When using the KEYENCE power supply unit BL-U1, BL-U2, N-42 or N-48, select the voltage level which can be supplied by the power supply unit. If a nonconforming power supply is connected, the BL-700 may be damaged.

• The BL-700 is a precision instrument. If the unit is dropped or shocked, it may be damaged. Take due consideration when transporting or installing the unit.

• Do not hold the cables when carrying the units. The units may hit each other and become damaged.

• Before installing the BL-700, read “2.4 Installation” of this manual carefully to select a suitable installation site.

• You cannot perform any operation for 5 seconds after turning ON the BL-700. During this time, the motor rotation stabilizes. Wait for a while after turning ON the BL-700, then start reading or another operation.

• At shipment, the protective seals are affixed to the transmitter and receiver to avoid fingerprints when mounting the unit. Be sure to remove the seals before use.

• Do not allow water, oil or dust to adhere to the transmitter and receiver. Adhesion of these materials may cause a reading error. If the surface is contaminated, gently wipe it with a soft cloth moistened with alcohol.

Chapter 1 Laser Safety Precautions

1.4 Safety Consideration

Use of controls or adjustment or the performance of procedures other than those specified herein may result in hazardous radiation exposure.

The laser beam is not harmful to the skin. There is, therefore, no danger in exposing arms or hands to the beam. The only possible health hazard is in exposing the eyes to the laser beam. Damage to the eyes can occur if the operator stares directly into the beam.

Follow the safety precautions below to ensure operator safety:

• Operate the BL-700 Series only according to the procedures described in this instruction manual.

Otherwise, injury may occur due to exposure to the laser beam.

• Do not disassemble the sensor head.

Laser emission from the BL-700 Series is not automatically stopped if the sensor head is disassembled. If you disassemble the sensor head for inspection or repair, you may be exposed to the laser beam. If the BL-700 Series malfunctions, contact KEYENCE immediately.

• Do not look directly at the laser beam.

Looking directly at the laser beam may result in serious eye injury.

• Protective enclosure

We recommend that you install a protective enclosure around the sensor head to prevent any person from getting near the sensor head during operation.

• Protective goggles

We recommend that you wear protective goggles when using the BL-700 Series.

• Stop laser emissions before cleaning the laser emission port.

Failure to stop the laser emission may expose eyes or skin to the laser beam.

• Check the laser beam path.

To prevent exposure to the laser beam due to specular or diffuse reflection, install a screen which offers the appropriate reflectance and temperature characteristics to interrupt the reflected laser beam. Do not install the BL-700 Series in such a way that the laser beam passes at eye height.

1.5 Safety Features Provided with the BL-700 Series

The BL-700 Series is provided with the following safety features. Make sure these features function correctly before operating.

• Laser emission caution LED (LASER ON LED)

During laser emission, the LASER ON LED illuminates. The LED ON status can be

checked through the laser protective glasses.

• Laser forced OFF command

Sending the laser forced OFF command (LOCK, see P.92) to the BL-700 can inhibit emission of laser beams. When working near the laser transmitter, be sure to use the laser forced OFF command to avoid looking into the laser beams.

When this command is selected, the bottom STABILITY LED flashes.

2.1.2 Power supply connections

• Be sure to match the polarities of the power supply when soldering the connections. Reversing the polarities will damage the unit.

• Make sure that the power supply provides a stable 5 VDC ± 5%. If the power supply does not function in the above range, it can damage the unit.

• Do not extend the power cable. A long power cable can cause a voltage drop, preventing the BL-700 from starting properly.

Note: If the power supply is UL rated, it must provide Class 2 output.

2.4 Installation

2.4.1 Operating environment precautions

Ambient environments

This unit is a precision instrument and you must take care in choosing the operating environment. Do not install the unit in place as shown below:

• The unit is exposed to direct sunlight, or the ambient temperature may fall below 0°C (32°F) or exceed 40°C (104°F) (Power supply: 0 to 50°C (32 to 122°F));

• The relative humidity may exceed the range of 35 to 85%, or condensation may occur due to rapid temperature changes;

• Corrosive gas or inflammable gas is present, or a high level of dust, salt, iron particles or soot is present;

• The unit is subject to vibration or impact;

• Water, oil or chemicals may splash the unit;

•A strong magnetic field or electric field is generated.

• The ambient illumination intensity exceeds the range defined in the specification in P.120.

In-panel installation

To mount the power supply unit BL-U1, BL-U2 or N-42, carefully observe the following instructions.

• Provide enough ventilation space.

• If the ambient temperature may fall below 0°C (32°F) or exceed 50°C (122°F), provide a fan or air conditioner.

• Do not mount this unit in a panel where a high voltage device is installed.

• Place this unit as far away from power lines as possible.

Note: The BL-700 conforms to the protective structure defined in IP-65 (excluding the power supply unit connected). Although installation environments subject to dust and water will not affect the BL-700, adhesion of dust or water drops to the transmitter/receiver may disable readout of bar codes.

Hints on correct use

• Trigger (TIM) input

Set the trigger input to be long enough to allow the laser beam to cover the entire bar code. If the trigger input needs to be on for only a short period of time, select one-shot mode.

• Influence from mirror surface

If a mirror surface (metallic surface) is near the bar code and the laser beam reflects off the mirror, the BL-700 may cause a read error. Protect the unit from the influence of a mirror surface by covering the surface or changing the bar code label position.

Bar code

• Bar code pitch

Do not place several bar codes in the field of the laser beam, unless you are in multi-label read mode (Multi 3).

If you use multi-label read mode (multi 3), the BL-700 can simultaneously read 2 to 4 bar codes in the field of the laser beam.

• Influence from photoelectric sensor

When using a photoelectric sensor to control trigger, block the sensor beam so it does not enter the BL-700 optical pickup. The beam from the photoelectric sensor can interfere with the BL-700, deteriorating reading performance. If this case, reposition the photoelectric sensor.

• Interference between the BL-700 units

When two BL-700 units are placed adjacent to each other with only a small separation, the mutual laser beams result in interference and will cause a readout error. To avoid interference, place the units as far apart as possible.

• When a bar code is stained or partially missing

Use a raster scan reader (BL-701/741/781) when a bar code is stained or partially missing. This raster scan readers scan several portions of the bar code. Normal portions of the bar code, even with stained or missing portions, can be read by the BL-700.

Page 39

Chapter 2 Connection and Installation

2.4.2 Installing the BL-700 series

Installation method

Use the mounting holes on the side panel to install the unit.

■ Installation with no mounting bracket

• Select screws of the proper length by checking the thickness of the plate used for mounting. (The screws provided are for use with the mounting bracket.)

• For the mounting hole diameter, see P.127.

■ Using the supplied mounting brackets

Vertical scanning

Horizontal scanning

• Use the set screw to secure the mounting bracket to the unit.

• For the mounting hole diameter, see P.127.

• When the insulating spacer is mounted, it can reduce the influence of noise from the mounting bracket.

Mounting angle and mounting distance

Set the angle and reading distance by referring to the read range characteristics and angle characteristics described on P.122 to P.124. The allowable reading distance and angle may vary depending on the narrow bar width of the bar code, the bar code size, and the readability of the bar code. Set these parameters after performing a test read of the required bar code using the unit.

Note: Do not set the unit at an angle at which the laser beam is perpendicular to the surface of the bar code. The beam will be fully reflected into the reader, making correct reading impossible (

➮

See P.124

The reading check test mode allows you to set the optimal reading position.

2.4.3 Installing the BL-U1*

There are 2 methods for installing the BL-U1:

■ When installing the BL-U1 directly

Pull out the 4 screw slots on the rear panel and screw them to the base.

■ When installing the BL-U1 to the DIN rail

1. Hook the BL-U1 to the DIN rail groove from its top. Push the BL-U1 bottom against the DIN rail until you hear a click.

2. Check that the DIN rail mounting notch is shaped like notch A below. If not, push the BL-U1 further.

3. To remove the BL-U1 from the DIN rail, pull out the notch until its shape turns from Fig. B to Fig. A. Then, disengage the BL-U1 from the DIN rail.

4. When you want to reinstall the BL-U1 to the DIN rail, return the notch from that of Fig. A to Fig. B.

Note: BL-U1 is not available in Europe.

2.4.4 Installing the BL-U2, N-42

Install the BL-U2 or N-42 using the mounting hole.

* The BL-U2 is 21 mm thick and the N-42 is 26 mm thick.

Chapter 3 Functions for Reading Operation

3.1 Read Operation

3.1.1 Scanning method

There are two methods for triggering the BL-700 to read bar codes; the “Level signal” method and the “One-shot signal” method. The example given for these two methods uses the “single label read mode” (

➮

see P.33

), which reads one bar code while trigger input turns on once, and uses the “after read” as the data-send mode (

➮

see P.32

■ Level signal trigger

When the trigger input turns on, laser emission begins and the unit begins reading. The laser turns off after reaching the specified decode count. Then, the unit sends the readout data.

*1. Set trigger input so that it stays on long enough for the laser beam to cover the

entire bar code.

*2. After the trigger input exceeds the preset input time, the laser begins to emit.

➮

See note on the next page.

*3. The communication time can be obtained from the following expression:

*4. The length of time that the OK/NG output is on can be changed to between 10

ms and 2.55 s.

*5. The OK/NG output turns on 5 ms after the data has been read (or trigger input

turns off in case of reading failure).

Note: 5 seconds after the power switch turns on or an UNLOCK command (

➮

see

P.90

) is sent, the unit will not start reading a bar code by turning on the trigger

input.

Chapter 3 Functions for Reading Operation

■ One-shot signal trigger

The unit detects the rising edge of the trigger input and starts reading bar codes for the preset input time. The laser beam turns off after reaching the specified decode count and the unit sends the readout data. The remaining actions are the same as those for level signal trigger.

1. After the trigger input exceeds the preset input times, the laser begins to emit.

Trigger input minimum ON time:

4 ms (when the trigger input value is 2 ms) 13 ms (when the trigger input value is 10 ms)

• The BL-700 can read up to 4 types of bar codes without changing the bar code type

setting (➮ see P.61).

• For general operation, see “Level signal trigger”

Choose “One-shot signal trigger” when the trigger input signal is very short or you want to set the input time.

• To use a one-shot trigger signal instead of trigger input, gently press the TEST switch

once (for less than 3 seconds) (➮ see P.vi).

NOTE: The BL-700 has a built-in AGC (auto gain control) circuit. It requires a maximum of 3 scans (4.3 ms) to adjust gain. The BL-700 generates a maximum of

4.3 ms delay until starting to read the data after the laser beam turns ON.

3.1.2 Data-send mode

In the single label read mode only, you can select from the two data send modes (OK/NG output on trigger) described below: In the multi-label read mode, you can only select the “send after reading” mode.

• Send after read

The unit outputs the communication and OK/NG signals after a successful read (trigger output turns on as many times as the preset decode count). This is the same operation as in the time chart described in “3.1.1 Scanning method”. Normally, this is the method you should use.

• Send at trigger input

The unit outputs the communication and OK/NG signal when the trigger input turns off (or the preset input time has passed if one-shot signal trigger is selected).

3.2 Read Modes

The BL-700 provides 4 types of read modes.

3.2.1 Single label read mode

This mode allows the unit to read one bar code during one trigger input signal. The operation and timing chart are described on page 30 to 32.

3.2.2 Multi-label read mode 1 (Multi 1)

This mode allows the unit to read several bar codes printed on one label as shown below during one trigger input signal. The unit outputs the readout data sequentially.

Multi-label read mode 1 operation

• In the multi-label read mode 1, the unit reads several bar codes continuously,

and outputs them sequentially as it reads while laser beam remains on and trigger input turns on after bar codes have been read (or during the preset input time if one-shot signal trigger is selected).

• To prevent the unit from reading the same bar code twice, the time for one bar

code to pass across the laser beam’s field and read, plus the repeat reading time must be set (100 ms to 25.5 s). During the repeat reading time, the unit cannot read the same bar code repeatedly, but can read different bar codes.

•A reading error is issued only when the unit cannot read any bar code while the

trigger input is on.

• For OK/NG output, “OK” turns on every time the unit reads a bar code and “NG”

turns on if the unit fails to read a bar code. (Comparison to the preset data is not performed.)

3.2.3 Multi-label read mode 2 (Multi 2)

As with multi 1 mode, this mode allows the unit to read several bar codes continuously while the trigger input is on. (The number of bar codes that can be read depends on the buffer capacity. See P.86.) The difference between the two modes is that multi 2 mode sends all the readout data at one time after the trigger input turns off.

Multi-label read mode 2 operation

• Multi 2 mode allows the unit to read several bar codes while the trigger input is

on (or during the preset input time if one-shot signal trigger is selected) and sends all the readout data at one time after the trigger input turns off (or after the preset input time is expired if one-shot signal trigger is selected).

• To prevent the unit from reading the same bar code twice, the time for one bar

•A reading error is issued only when the unit cannot read any bar code while the

trigger input is on.

• For OK/NG output, after trigger input turns off, “OK” turns on if the unit reads at

least one bar code and “NG” turns on if the unit fails to read a bar code. (Comparison to the preset data is not performed.)

Reading data format

• Each data packet is separated by a comma (, : 2CH) (intermediate delimiter).

• The unit sends as many data packets the number of bar codes read.

3.2.4 Multi-label read mode 3 (Multi 3)

As described in multi-label read modes 1 and 2, this mode also allows the unit to read several bar codes (up to 4 codes) while the trigger input is on. The unit sends the readout data at one time according to a specified sequence after the trigger input turns off. When up to 4 codes are in the laser beam’s field, the unit can simultaneously reads all of them.

Operation of multi-label read mode 3

This mode allows the unit to continuously read each one of 4 bar code types “Code 1”, “Code 2”, “Code 3”, and “Code 4” as specified in the “code setup” of the setup software (

➮

see P.61

). If 3 types are specified in the “code setup”, the unit reads 3

bar codes (each of 3 types). If 2 types are specified, the unit reads 2 bar codes.

The following time chart is given.

* The above example chart is with all 4 codes specified in the “code setup” of the

setup software.

• The bar code reading sequence is not fixed.

• The unit communicates the readout data in the order of Code 1 to Code 4. After

the trigger input turns off, the unit sends all the data at one time.

• For OK/NG output, “OK” turns on if the unit reads all the specified Codes 1 to 4

and “NG” turns on if the unit fails to read at least one bar code. (Comparison to the preset data is not performed.)

Reading data format

• Each data packet is separated by a comma (, : 2CH) (intermediate delimiter).

• If an read error occurs on any one of Codes 1 to 4, or the corresponding bar

code does not exist, “ERROR” (➮

see P.87 for the reading error codes

), instead

of the read data is sent.

Suppose that the following codes are specified: Code 1: CODE39, 10 digits Code 2: EAN/UPC, 13 digits Code 3: None Code 4: CODE39, 8 digits When the unit successfully reads all 3 types of codes:

When the unit fails to read Code 1 (CODE39, 10 digits)

When the unit fails to read Code 1 (CODE39, 10 digits) and Code 4 (CODE39, 8 digits)

• When the same type of data having the same digits is specified to all Codes 1

to 4, the unit sends the data in the reading order.

Example

Suppose that the following codes are specified: Code 1: CODE39, 7 digits Code 2: CODE39, 7 digits Code 3: CODE39, 7 digits Code 4: CODE39, 7 digits

Note: The unit cannot read the bar code having the same content twice while trigger input turns on once.

3.3 Label Orientation Mode

As shown below, this mode allows the unit to read bar codes only in the specified orientation when bar code labels are moving both in the forward and reverse orientations.

* Normally, the unit can read bar codes regardless of the orientation.

• An reading error is issued when the unit reads a bar code label running in the

orientation which is not specified.

• The above chart applies to the single label read mode. You can also use this

mode together with the desired multi-label read mode. However, in any case, the unit reads bar codes running in the specified orientation only.

• You can specify the orientation individually for Codes 1 to 4, such as specifying

“forward orientation” for Code 1, and “reverse orientation” for Code 2.

3.4 Test Mode

Test mode can be used for the bar code reading test. Because trigger input is not required, this mode allows you to perform a reading test easily. You can select one of the following 3 methods to enter the test mode.

3.4.1 Reading rate check mode

The unit scans a bar code100 times and analyzes how many times it can decode the scanned data (reading rate). This mode is useful in the following cases:

• When adjusting the mounting distance and angle

• When verifying the reading stability of the bar code to be used

This mode is enabled when the bar code label stays in the given position.

■ Operation

Follow the instructions below:

1. Hold down the TEST switch for 3 seconds. (Release the switch when one

STABILITY LED illuminates.)

2. The BL-700 then enters the mode in which the laser emission is always ON.

Attempt to use the BL-700 to read bar codes.

3. Depending on the reading rate, the BL-700 displays the STABILITY LEDs as

listed. By checking the display, adjust the reading distance and angle so that the reading rate reaches the highest level.

4. In the test mode, the unit outputs the serial communication data in the following

format every 100 scans. By connecting the BL-700 to a PC and using a BL setup software terminal, the following data can be displayed on the PC screen.

➮

See P.79 for details of operation.

* ON/NG LED turns ON but OK/NG output does not turn ON.

5. Press the TEST switch again to exit the test mode.

Gently pressing the TEST switch once (for less than 3 seconds) will cause the BL-700 to read a bar code once. (It also performs serial output and OK/NG output.)

3.4.2 Tact check mode

In this test mode, the unit counts how many scans can be decoded (the decode count) while reading one bar code. This mode is useful when testing which line speed can be expected when actually implementing the BL-700 system on the line. This is enabled when the bar code label is moving.

■ Operation

Follow the instructions below.

1. Hold down the TEST switch for 5 seconds. (Release the switch when two

STABILITY LEDs illuminate.)

2. The BL-700 then enters the mode in which the laser emission is always ON.

Attempt to use the BL-700 to read bar codes moving on the line.

3. Depending on the decode count, the BL-700 displays the STABILITY LEDs as

listed below 0.2 seconds after the last bar code has passed the laser emission range. By checking the display, you can recognize how much stability the BL700 ensures during readout. To display the readout count, follow the procedure in 4 to display the data on the PC screen.

Tips

Page 54

Chapter 3 Functions for Reading Operation

The BL-700 continues to read the data while the laser beams scan the bar codes. Thus, the STABILITY LEDs are not ON. When the bar code reading stops for 0.2 seconds, the BL-700 stops scanning and turns ON the STABILITY LEDs.

4. In the serial communication mode, the BL-700 outputs the data in the following

format. By connecting the unit to a PC and using the BL setup software terminal, the following data can be displayed on the PC screen.

➮

See P.77 for details of operation.

* ON/NG LED turns ON but OK/NG output does not turn ON.

*A value greater than 9999 cannot be added.

5. When reading the same bar codes continuously within 0.2 seconds, the BL-700

cannot separate the data and continues scanning to add the readout count. When reading different bar codes within 0.2 seconds, continuous scanning is enabled.

6. Press the TEST switch again to exit the test mode.

Note 1: When the unit is running in test mode, the laser beam remains on, which can shorten the laser’s service life. Select the test mode only when you need to perform a test read. Avoid long emission times.

Note 2: When using the “additional information” (

➮

see P.46 to 47

) in the test mode, the selected data is added in the same manner as in the normal operation mode. However, only when selecting the reading rate check mode, the decode count and scan count are not added to the analyzed results.

To start the test mode, the following alternative method is available in addition to the method of using the TEST switch.

• Start the test mode using the serial commands (➮ see P.89)

Send the test mode start command (TEST1, TEST2) to start the test command. By entering TEST1 or TEST2 and pressing [RETURN] from the provided setup software terminal, the test mode is started.

• Start the test mode by turning the trigger input ON (➮ see P.58)

Turning the timing input ON enables the setting to start the test mode. When this is set, the trigger input cannot function normally. Also, startup using the serial command is disabled. Use the setup software to perform the settings.

• Start the test mode by turning power ON (➮ see P.58)

Setting is available to start the test mode immediately at power-ON. Use the setup software to perform the settings.

3.4.3 Online test mode

When the BL-700 always reads the bar codes, the reading stability can be displayed in real time using the STABILITY LEDs. This mode is called online test mode.

■ Setting

1. To set the online test mode, send the following command from the BL setup

software terminal. To use the terminal,

see P.77

Command to be sent: #TEST1 Send-data: OK

When OK is returned to the command sent, it indicates the mode is set. This setting is valid only when power is ON. The setting data is reset after power is turned OFF.

2. According to the setting, start the BL-700 to read bar codes normally. In the

online test mode, the send-data and STABILITY LEDs are displayed after the trigger input turns OFF.

3. The STABILITY LEDs turn ON as shown below, indicating how many times the

unit can read the data correctly.

4. The BL-700 sends the data in the following format.

The information on the scan count during one trigger-ON and the correct readout count is appended to the data. The scan count includes the cases where no bar code is set.

5. To quit the online test mode, send the following command.

Command to be sent: #QUIT Send-data: OK

When OK is returned to the command sent, it indicates the mode is canceled.

Online test mode operation is the same as when setting the following from the BL-700 setup software. To save the online test mode setting in the BL-700, set the following using the setup software.

• Data adding function — Add decode count.

Add scan count.

• STABILITY LED — Display the data.

Note: When you try to enter the test mode by turning on trigger input, you cannot use the serial command to enter the test mode. Commands should be entered in all uppercase characters.

3.6 Preset Function (Compare with:)

3.6.1 What is the preset function?

The BL-700 can store one bar code as preset data. It compares the preset data to the bar code data actually read and outputs an OK/NG signal to whether there is a match. Using the BL-700 preset function, you can prevent the wrong products from entering the line without using a PC.

If no preset data is registered, the unit outputs OK when it successfully reads a bar code and NG when it fails to read a bar code.

➮

See P.30 to 37 for output timing.

Use the setup software and serial command to register the preset data (

➮

See

P.68 and P.101

Note: The bar code actually read can be compared to the preset data only in the single label read mode.

➮

See P.136 if you want to use CODE93.

➮

See P.137 if you want to use CODE128.

Chapter 3 Functions for Reading Operation

3.6.2 Wildcard Symbols (“!” and “?”)

Using “!” and “?” in the preset data allows for flexible settings.

?: Does not define numeric values (characters) of certain digit(s) of the bar code.

!: Ignores numeric values and symbols within the dot box and recognizes the bar

codes as the same group.

Setting examples

1. “ABC?” ABCD (OK), ABC3 (OK), ABC (NG), ABCDE (NG)

2. “ABC!” ABCD (OK), ABC3 (OK), ABC (OK), ABCDE (OK), AB (NB)

3. “?????” Any 5-digit bar code will be OK.

4. “!CDE” ABCDE (OK), 3CDE (OK), CDE (OK), ABBDE (NG), ADE (NG)

5. “A!E” ABCDE (OK), A3CE (OK), ABCD (NG), AE (OK)

Note: You can use “!” only once in the setting.

If you do not register preset data, “!” is automatically registered. Therefore, when the unit successfully reads a bar code, “OK” is output; when the unit fails to read, “NG” is output.

49123456 49125256 4912AB56

49123456 4912C 4912

When using “?” data as “4912??56”, 2 digits positioned in “??” can contain any numeric values (or characters), expanding the allowable range. Identifies all the bar codes to be OK as long as the beginning or ending strings match.

When using “!” as “4912!”, any bar code which begins with “4912” will be OK. When using “!” as “!4912”, any bar code which ends with “4912” will be OK.

Adds the number of successful scans during one bar code reading (decode count) to the end of the readout data (up to 9999 count). However, this decode count is never less than the preset decoding match count. This function can be used to check reading stability and code label quality.

* The value is zero-suppressed.

When using this function, output turns on at a different time from normal operation.

• In single label read mode, output turns on after one bar code has been read

(after trigger input turns off). Even if you set the data send to “after read”, the data is forced sent after trigger input turns off.

• In multi-label read mode 1, a bar code passes across the laser beam’s field,

after repeat read time, and is finally output.

• In multi-label read mode 2 or 3, operation is the same as when you do not use

the decode match count adding function.

■ Scan count add function (valid only when using the read count add func-

tion)

Adds the number of scans, including when no bar code exists, to the end of the decode count (up to 9999).

* The value is zero-suppressed.

3.8 Max. Code Length (Designated Digit ) Output Function

This function allows you to output the designated digit(s) as desired from the readout bar code data. For example, from bar code data “49123456”, you can extract “1234” for output.

Setting digits to be output

Set the digits to be output as shown below. Individually set the digits for codes 1 to

1. Set the direction to designate.

* Set from which direction you want to start counting.

2. Set how many digits you want to designate for output starting from the designa-

tion start digit in (2) (designation effective digits).

* The actual setting order is (1) (3) (2).

3. Set from which digit you want to begin designation (destination start digit).

Example

Designating and outputting “34” from bar codes “158423421” and “58423421”

Designate 2 digits starting from 3rd digit by counting reversely.

• Regardless of the designated direction, the data is output forward in the communica-

tion application.

• When the bar code group includes those having different digits, take special care on

the designated direction when setting the digits to be output.

• When comparing to the preset data, all the digits of the bar code are used.

4.4 Sending/Receiving Settings

To send the updated settings to the BL-700 and to read the settings from the BL700, perform the following procedure.

Sending updated settings to the BL-700

To send updated settings to the BL-700, perform the following procedure.

1. Press the BL-700 TEST switch for 8 seconds. When the 1st, 3rd and 5th STA-

BILITY LEDs from the top flash simultaneously, the communication protocol is temporarily set as indicated below (this status is called “setting data send/ receive waiting status”).

• Baud rate: 9600 bits/s

• Data length: 7 bits

• Parity: Even

• Stop bit length: 1 bit

• PLC link: Disabled

• Multi-drop link: Disabled

If you know the current communication parameter settings of the BL-700, this step is not necessary. You can send data to the BL-700 by setting the communication parameters of the host computer using [COM PORT] so that they conform to the current settings of the BL-700. However, if PLC link is enabled, you cannot send data to the BL-700 without performing this step because the handshaking protocol is set for PLC link only.

2. Click on [COM PORT] to set the communication parameters of the host com-

puter according to the values listed in the step 1. (above procedure). Select an RS-232C port, and click on [OK].

3. Click on [Send settings (Save in BL EEP-ROM)]. The updated settings are then

sent to the BL-700.

4. If the settings were successfully sent to the BL-700, the following message

appears.

If the host computer failed to send the data to the BL-700, the following message appears.

If this message is displayed, check the following points:

• Check that [COM PORT] is set as shown in (1) when the 1st, 3rd and 5th STABILITY LEDs from the top flash simultaneously (when in “setting data send/receive waiting status”).

• Check that the power to the BL-700 is ON.

• Check that the RS-232C cable pin assignment of the BL-700 is the same as that of the host computer.

Page 89

Chapter 4 Installing the Setup Software

Reading the current settings of the BL-700

To read the current settings of the BL-700, perform the following procedure. (This procedure is almost the same as the procedure for sending settings.)

1. Press the BL-700 TEST switch for 8 seconds. When the 1st, 3rd and 5th STABILITY LEDs from the top flash simultaneously, the communication protocol is temporarily set as indicated below (this status is called “setting data send/ receive waiting status”).

• Baud rate: 9600 bits/s

• Data length: 7 bits

• Parity: Even

• Stop bit length: 1 bit

• PLC link: Disabled

• Multi-drop link: Disabled

If you know the current communication parameter settings of the BL-700, step 1. is not necessary. You can send data to the BL-700 by setting the communication parameters of the host computer using [COM PORT] so that they conform to the current settings of the BL-700. However, if PLC link is enabled, you cannot send data to the BL-700 without performing step 1., because the handshaking protocol is set for PLC link only.

2. Click on [COM PORT] to set the communication parameters of the host com- puter according to the values listed in step 1. Select an RS-232C port and click on [OK].

3. Click on [Send settings (Save in BL EEP-ROM)]. When you click on [Read BL settings], the settings of the BL-700 can be read on the host computer.

Chapter 5 Serial Communication

5.1 Serial Communication

The BL-700 communicates with the PC via the RS-232C serial port. This enables you to change the BL-700’s settings from your PC.

Communication types

The BL-700 provides the following two communication types:

• Data communication Sends read bar code data from the BL-700 to the PC.

• Command communication Changes the BL-700’s settings by sending a command from the PC to the BL-

700.

* All communication is performed using ASCII codes.

Communication setup

Configure the setup for BL-700 and the PC before attempting serial communication.

• Setup of BL-700 Set the following parameters for the BL-700 using the setup software.

• Baud rate, Data bits, Parity, Stop bit

• Communication protocol

• Header/Delimiter

• Read error code

• PC setup Based on the BL-700’s settings, set the communication parameters on the PC using the “Ports” setting in the Windows Control Panel/System/Device Manager.

• The following communication parameters are the default settings for the BL-700:

• Baud rate: 9600 bps

• Data bits: 7 bits

• Parity: Even

• Stop bit: 1 bit

Set the PC according to the above settings before attempting communication.

• The BL-700 is set, temporarily, to the default settings for 5 seconds after the power switch is turned on.

When the current settings of BL-700 is not certain, send the command “SSET” and a [CR] to the BL-700 from your PC with 5 seconds after power-up. This causes the BL700 to remain at its default settings and you can communicate with the BL-700 at the default settings. For information on checking the BL-700’s current settings, see “Details on Parameter Setting Commands” on page 92. For information on changing the above communication parameters see “Description of Parameter Setting Commands” on page 94. When the BL-700 TEST switch is pressed for 8 seconds, the 1st, 3rd and 5th STABILITY LEDs from the top flash, indicating that the communication parameters are set as above. (Press the TEST switch again to reset the settings.)

Note: All commands should be entered in all uppercase characters. The BL cannot accept lowercase characters.

5.2 Details on Data Communication

Communication protocols (Hardware handshaking)

The BL-700 supports the following four handshaking protocols.

■ No Handshaking

• The BL-700 sends read data to the PC without using any handshaking protocol.

■ PASS/RTRY Handshaking

• After sending the read data, the BL-700 waits for a response from the PC. The response is either a PASS command or a RTRY command. The PASS command (quit) indicates that the PC has successfully received one data packet. The BL-700 then prepares for the next data transmission.

• The RTRY command (request to re-send) indicates that the data was not transmitted successfully. The command is a request to the BL-700 to re-send the data. The BL-700 sends the same data again and then waits for the response.

After the BL-700 once receives PASS, the BL-700 sends back no data even if RTRY is sent to the BL-700.

• The BL-700 can continue to read while waiting for the PASS command. The data is stored in the BL-700’s transmission buffer.

➮

For the capacity of the transmission buffer, see P.86.

If the amount of stored data exceeds the capacity of the transmission buffer, the BL-700 sends back [Header]OVER[Delimiter] to the PC, and clears all data stored in the transmission buffer. The BL-700 stops operation while clearing data. It recovers by sending PASS to [Header]OVER[Delimiter].

• PASS and RTRY can be received in either communication format: PASS <CR> or <STX> pass <ETX>. You can also add <ESC> to the beginning, or <LF> to the end of the format.

Note 1: The BL-700 can receives other commands while waiting for the PASS command. In this case, the BL-700 sends back an immediate response (e.g. OK).

Note 2: When the SSET command (

➮

see P.92

) is sent to the BL-700 while the BL-700 is waiting for the PASS command, the BL-700 clears the data stored in the transmission buffer, and enters the setting mode.

Chapter 5 Serial Communication

■ ACK/NAK Handshaking

The ACK/NAK handshaking uses <ACK> (06H) and <NAK> (15H) instead of PASS and RTRY used in the PASS/RTRY handshaking, respectively. With these protocols, the BL-700 sends back different characters, but performs the same operation.

■ RTS/CTS Handshaking

• When the PC’s RTS (BL-700’s CTS) signal turns off, the BL-700 becomes

ready for data transmission. When the PC’s RTS signal turns on, the BL-700 starts data transmission.

• When the PC’s RTS signal is off, the BL-700 can still read. In this case, data is

stored in the BL-700’s transmission buffer (see below). If the amount of stored data exceeds the capacity of the transmission buffer, the BL-700 sends back [Header]OVER[Delimiter] to the PC, and clears all data stored in the transmission buffer. The BL-700 stops operation while clearing data. It recovers when the RTS of the computer turns ON.

Note 1: The RTS/CTS handshaking cannot be used for RS-422A communication.

Note 2: The RTS/CTS protocol can be used together with other handshaking

protocols.

Note 3: When the PC’s RTS signal is off, the BL-700 does not sends back a response to the PC.

Capacity of transmission buffer

The BL-700’ s transmission buffer can store 400 bytes (400 characters). The number of characters stored in the transmission buffer for each data packet is the number of characters in the data (including additional data such as the number of decoding match count) plus an additional five characters indicating the data’s attributes. When multi label reading mode 2 or 3 is used, these five attribute characters are added to each data packet.

Example 1

When the number of bar code digits is 10 (with no additional data) 400 ÷ (10 + 5) = 26 The transmission buffer can store 26 pieces of data.

Example 2

When the number of bar code digits is 20 (with no additional data) 400 ÷ (20 + 5) = 16 The transmission buffer can store 16 pieces of data.
