PAGE 10
1.1 BL-180 Connections 1.1 BL-180 Connections 1.1.1 Wire colors and signal types The following wires extend from the BL-180. Solder the required wires to a connector to connect the BL-180 to a computer/controller.
PAGE 11
1.1 BL-180 Connections OK/NG output This output signals whether the readout data is the same as the preset data. When no preset data has been registered, the signal indicates bar code read status. It is an NPN open-collector output. Internal circuit BL-180 1kΩ OK/NG Write/Gray GND Black Load + *Rated load: 24 VDC (100 mA) max. 1.1.4 RS-232C Connections Note This BL-180 setup software applies to port 1 and port 2 only. Communication cannot be performed with another port.
PAGE 12
1.1 BL-180 Connections 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-180 may cause a read error.
PAGE 13
1.1 BL-180 Connections Bar code height The bar code height must be at least 3 mm. However, adjust any bar code of 3 mm or more height so that it is arranged from one end to the other on the lightreceiving axis.
PAGE 14
1.2 Installing the BL-180 Series 1.2 Installing the BL-180 Series Installation method Use the mounting holes on the side panel to install the unit. To prevent dust from entering the unit, seals have been placed over the screw holes. Remove the seals before mounting.

Chapter 2 Functions for Reading Operation
PAGE 18
2.1 Read Operation 2.1 Read Operation 2.1.1 Scanning method There are two methods for triggering the BL-180 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 page 12), which reads one bar code while trigger input turns on once, and uses the “after read” as the data-send mode (see page 11). Level signal trigger When the trigger input turns on, LED emission begins and the the unit begins reading.
PAGE 19
2.1 Read 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 LED 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. Trigger input *1 Bar code Preset input time Preset input time LED beams Communication time OK/NG output OK/NG NG 1.
PAGE 20
2.2 Read modes 2.2 Read modes The BL-180 provides 4 types of read modes. 2.2.1 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 10. 2.2.2 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.
PAGE 21
2.2 Read modes 2.2.3 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 page 48.) The difference between the two modes is that multi 2 modesends all the readout data at one time after the trigger input turns off.
PAGE 22
2.2 Read modes 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 page 32). 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.
PAGE 23
2.2 Read modes 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 Header Note ABCD123 , XYZ3333 , 1234567 , KEYENCE , Delimeter The unit cannot read the bar code having the same content twice while trigger input turns on once.
PAGE 24
2.3 Label orientation mode 2.3 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. Forward orientation Reverse orientation 4 9000000 BL-180 OK/NG STABILITY 4 9000000 Normally, the unit can read bar codes regardless of the orientation.
PAGE 25
2.4 Test Mode 2.4 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. Send the command Enter test mode by sending the serial command for the test mode (TEST1, TEST2). Commands should be entered in all uppercase characters.
PAGE 26
2.4 Test Mode • The read count can be up to 9999. • Although an OK/NG signal is not output, the OK/NG LED lights (see page 19). Note When the unit is running in test mode, the LED beam remains on, which can shorten the LED’s service life. Select the test mode only when you need to perform a test read. Avoid long emission times. When using the “additional information” (see page 21 to 22) in the test mode, the selected data is added in the same manner as in the normal operation mode.
PAGE 27
2.5 STABILITY LEDs 2.5 STABILITY LEDs STABILITY LEDs allows you to easily check reading stability. STABILITY LEDs light only when the test mode gets started or the decode count adding function (see P. 34) is used. Indication of reading stability When reading rate check mode is selected STABILITY LEDs light according to the reading rate shown in the table below. Although, in the test mode, the unit does not output an OK/NG singnal, the OK/NG LED lights as below.
PAGE 28
2.6 Preset Function (Compare with:) 2.6 Preset Function (Compare with:) 2.6.1 What is the preset function? The BL-180 can store one bar codeas 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-180 preset function, you can prevent the wrong products from entering the line without using a PC.
PAGE 29
2.7 Additional Information 2.7 Additional Information When sending the bar code data, you can add the following data to the readout data. Additional information types Decode match count add function 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.
PAGE 30
2.7 Additional Information label orientation add function Adds the orientation of bar code travel before the readout data. Delimiter : r r =F R Readout data :Forward :Reverse If an read error occurs, this information is not added.
PAGE 31
2.8 Max. Code Length (Designated Digit ) Output Function 2.8 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.

Chapter 4 Serial Communication (RS-232C/RS-422A)
PAGE 54
4.1 Serial Communication 4.1 Serial Communication The BL-180 communicates with the PC via the RS-232C serial port. This enables you to change the BL-180’s settings from your PC. Communication Types The BL-180 provides the following two communication types: Data communication Sends read bar code data from the BL-180 to the PC. Command communication Changes the BL-180’s settings by sending a command from the PC to the BL180. All communication is performed using ASCII codes. 4.1.
PAGE 55
4.2 Details on Data Communication 4.2 Details on Data Communication 4.2.1 Communication Protocols(Hardware handshaking) The BL-180 supports the following four handshaking protocols. No Handshaking The BL-180 sends read data to the PC without using any handshaking protocol. Read data PASS/RTRY Handshaking After sending the read data, the BL-180 waits for a response from the PC. The response is either a PASS command or a RTRY command.
PAGE 56
4.2 Details on Data Communication RTS/CTS Handshaking When the PC’s RTS (BL-180’s CTS) signal turns off, the BL-180 becomes ready for data transmission. When the PC’s RTS signal turns on, the BL-180 starts data transmission. When the PC’s RTS signal is off, the BL-180 can still read. In this case, data is stored in the BL-180’s transmission buffer (see 4.2.2 below).
PAGE 57
4.2 Details on Data Communication 4.2.4 Read Error Code If the BL-180 fails to read a bar code, the B-500 sends back a read error code. The initial setting of the read error code is as follows: Header ERROR Delimiter The read error code can freely be changed (within 8 characters). The BL-180 can be set to send no error code (see page 38).
PAGE 58
4.3 Command Communication 4.3 Command Communication The BL-180 includes commands to directly operate the BL-180 (direct control commands) and the commands used to change or confirm the BL-180’s settings (parameter setting commands). 4.3.1 Setup of Direct Control Commands Communication procedure Command Response 1. Send a direct control command from the PC to the BL-180. 2. After receiving the command, the BL-180 sends back an OK response and executes the required operation.
PAGE 59
4.3 Command Communication 4.3.2 Explanation of Direct Control Commands The following describe direct control commands in details. Read operation control This command specifies the data read timing. [LON] Trigger on Command: LON Response: None [LOFF] Trigger off Command: LOFF Response: None • Even when the read operation is controlled with these commands, the BL-180 performs the same operation as with the trigger input (see page 10 to 12).
PAGE 60
4.3 Command Communication Clearing transmission buffer [BCLR] Clears data stored in the transmission buffer. Command: BCLR Response: OK Shift to setting mode [SSET] Enters the setting mode (see page 51). Command: SSET Response: OK 4.3.3 Details on Parameter Setting Commands The following describes how to change the BL-180’s settings through command communication. You can use the setup software to change the BL-180’s settings instead of these commands. Communication Details 1.
PAGE 61
4.3 Command Communication 4.3.4 Response Error Code When an incorrect command is sent to set parameters, the BL-180 sends back data indicating the cause of the error (error code). For the commands corresponding to the error codes, see the error code column given in the table on the following pages. Error code Cause of error 00 01 02 03 Undefined command. Command format is incorrect. Nothing corresponds to the number in the command. “m” value (codes 1 to 4) is other than 0 to 3.

Power Supply BL-U1 5 Communication 5.1 Outline of Communication types You can perform all multidrop link communication by sending commands from the host computer to the BL series. The communication of the multidrop link is classified into the following two types: Data communication For sending read data from the BL-series to the host computer. When data receive commands (polling commands) are sequentially sent to each BL series connected to the host computer, the read data is sent to the host computer.

Power Supply BL-U1 6 Precautions for Programming • Since the multidrop link requires communication of many commands, the host computer must have high processing ability. As the number of connected BL series increases, the host computer needs higher data processing speed. When the host computer’s processing speed is insufficient, the BL series’ transmission buffer will become full, and the BL series will send back the following response.
