the construction of highly functional, long-distance wireless ID systems for material control and logistics. V720S-BC5D4A (hereinafter called “Reader/Writer”) is the device to communicate with Tag (manufactured by OMRON) of the V720-series that use two kinds of I-CODE chips manufactured by Philips Semiconductor (Product name: SL1 ICS30 01, Common name: I.CODE1; and Product name: SL2 ICS20, Common name: I.CODE2). The chip SL2 ICS 20 is fully conforming to ISO/EC15693. The Reader/Writer can be connected to personal computers (PCs) and Programmable Logic Controllers (PLCs) to process large amounts of data flexibly with simple commands.

In multiple simultaneous access mode, if there is more than one Tag in the communications area, the RFID System reads and writes data from and to all the Tags at one time. In selective access mode, the user can specify the Tags from and to which data is read and written. In FIFO read/write mode, the RFID System reads and writes data to one Tag after another as they come into the communications area. ■Support of off-line EAS Mode The Reader/Writer can operate in EAS mode (see 3-7 in Section 3) as a standalone device, with no need to connect with the host. ■I/O function By issuing commands from the host, the user can operate three input points and four output points. ■Protection Construction The protection construction IP60 has been achieved in the Reader/Writer. 1-2 1-2 System Configuration 1-2 1-2-1 Example of 1-to-1 System Configuration The V720S-BC5D4A has a built-in serial interface conforming to RS-232C and RS-485, thus making it possible to communicate with personal computers and PLCs. All the ordinary communication processes take place via commands from the host.

You have to set either of the Chip Operating Modes in accordance with the Tag you choose. The functions or command types/formats vary, depending on the Chip Operating Mode. The factory default is ISO Mode (I.CODE 1 Mode for Ver1.10 and lower). The mode is set by the Chip Operating Mode Switch Command (TY). Operating Mode ISO Moed I.CODE１ Mode Operation Processes the Tags with ISO/IEC15693 Standard Chips (I.CODE SLI). I.CODE1-Mode specific functions or commands are disabled. Processes the Tags with I.CODE1 Chips. ISO-Mode specific functions or commands are disabled. 3-1-2 Online Mode /Offline Mode The Reader/Writer operates in either Online Mode, in which commands are given by the host, or in Offline Mode, in which the EAS function (refer to SECTION 3-7) performs the configuration, when the host is disconnected and the communication test between the antenna, the Reader/Writer and the Tags. The factory default is set to Offline mode. To change the mode to the Online Mode, connect the host and execute the Stop Command (ST). To always start the Reader/Writer in the Online Mode, the default mode is disabled using the Offline Mode Setting Command (FL). When the Reader/Writer is turned on in Online Mode, it remains in a stand-by state, until commands from the host are received. In the Offline Mode, the Reader/Writer starts detecting the EAS-enabled Tags (the EAS function mounted on the Tags is not disabled) from the moment it is turned on in this mode the COMM LED remains flashing. At the entrance of an EAS-enabled Tag into the antenna communication area, the external output turns ON for the specified time. The OUT1 LED light indicates normal communication between the Reader/Writer and the Tags . To check the communication status in the Offline Mode, the EAS on the Tags must be enabled in advance. Note: ●If the type of Tags used and the chip operating mode setting do not match, the Reader/Writer will not respond to the Tags. The No Tag Error （code: 72） results. ●Specifying the commands or functions unavailable in the specified Chip Operation Mode will result in a Format Error (code: 14). ●The communication test in Offline Mode is performed with the EAS on the Tags enabled. The communication by the EAS function takes longer compared to Read/Write operations performed by other functions. The communication distance in the Online Mode should be checked using the actual commands. 3-2 3-2 Communication Modes 3-2 This Reader/Writer has five communication modes to be selected by each command corresponding to the number and/or state of Tags in the communication area. Each mode is activated by specifying the communication in the command data. 3-2-1 Single Access Single Access is used to read data from or write data on the only Tag that exists in the Antenna Communication Area. The execution timing can be selected from Trigger, which executes immediately, Auto, which waits for the Tag to enter the communication area and executes, or Repeat, which repeats the execution for the Tag in the communication area. Be sure to have only one Tag in the communication area. Multiple Tags in the Antenna Communication Area prevents the antenna from communicating normally. ：In the I.CODE1 Mode, the Tag is processed only once at the entry into the communication area. It can be reprocessed once it is outside the area again. 3-2-2 FIFO Access FIFO Access is used to read data from or write data on the Tags sequentially in the same order they entered the antenna communication area. (FIFO First In First Out). The execution timing can be selected from Trigger, which executes immediately, Auto, which waits for the Tags to enter the communication area and executes, or Repeat, which continues to wait for the Tags to enter the communication area. Since every Tag finished with communications is set to access prohibit, communications will be possible if only one Tag newly arrives in the communication area of the Antenna where more than one Tag exists. An error results, however, if two or more Tags arrive in the communications area simultaneously. Once an access-prohibited Tag leaves the communications area, access to the Tag is enabled again. 3-3 3-2 Communication Modes 3-2-3 Multiple Access 3-2 Multiple Access is used to read data from or write data on the Multiple Tags in the Antenna Communication area simultaneously. Communications with Multiple Tags in the communications area is available. (This function is also called 1:N Access or Multiple Tag Simultaneous Access). The execution timing can be selected from Trigger, which executes immediately, or Repeat, which continues to wait for the Tags to enter the communication area. In I.CODE1 Mode, specify the appropriate tag-number code in command data according to the number of Tags that exist in the communication area (refer to SECTION 5-2-5). The Duplicate Communication Protecting Function is useful for unstable Tags in the Antenna Communication Area (refer to SECTION 3-8 for details). 3-2-4 Selective Access Selective Access is used to read or write data on specified Tags among the multiple Tags in the communication area. In ISO Mode, communication with specific Tags is achieved by first reading the Tag UIDs (unique codes) in Multiple Access Mode and then by specifying them. It is recommended that the UID/SNR addition option of the Command Processing Procedure Setting should be used. It is especially convenient since data readouts and UID acquisitions are performed by a single command. In I.CODE1 Mode, the Tag Detection Command that assigns numbers to the Tags in the communication area in Multi Access Mode is performed first, and then the Tag Designation Command that specifies the assigned numbers is performed to launch the communication with the specific Tags. 3-4 3-2 Communication Modes 3-2 3-2-5 Fast Read Access: I.CODE1 Mode Only The Fast Read Access speeds up the data readout in I.CODE1 Mode. The execution timing can be selected from Trigger, which executes immediately, Auto, which waits for the Tag to enter the communication area and executes, or Repeat, which repeats the execution for the Tag in the communication area. The function operates the same way as in Single Access mode when the Tag number code is set to 0; in other cases it is the same as in Multiple Access Mode. [When the Tag number code is set to 0 (Single Access Mode)] By selecting the Trigger or Auto execution timing, the function executes the same operation as that in normal single access mode but in a shorter period of time. When the Repeat execution timing is selected, the function continuously returns data while the Tags are present in the communication area, this is useful in confirming the communication area. [When the Tag number code is set to those other than 0 (Multiple Access Mode)] The only execution timing available is Repeat, since the function employs a simple version of the communication sequence, some Tag data may be unreadable under the condition where the responses from the Tags collide frequently. In addition, the function processes and responds to the same Tags repeatedly while they are present in the communication area. This function should be used when there is a low number of Tags in the communication area. When there are a greater number of Tags, the Multiple Access Mode should be used. The Duplicate Communication Protecting Function is useful to avoid multiple responses returned to the same Tag. (Refer to SECTION 3-8). Note: ●For the I.CODE1 Communication Modes used under the conditions, where Multiple Tags exit in the Antenna Communication Area (Multiple Access, Selective Access, or Fast Read Modes), the Tag Number Code must be specified. The maximum number of Tags allowed in the communications area is set previously. (Refer to SECTION 5-2-5 for details). 3-5 3-3 Memory Check Function I.CODE1 Mode Only 3-3 By adding a check code to the data in the Tag, you can detect data errors due to the Tag memory (EEPROM) being overwritten, service life, and unforeseen factors. The check code uses the CRC code of the generating polynomial X16 + X12 + X5 + 1. A memory check is performed using the Memory Check Command (MC), which writes the check code, and the Memory Calculation Command (MK), which verifies the check code. In the check block defined using the header page and the number of pages, the target calculation area is the area except for the last page of the block, and the last page is the check code area. The check code uses two bytes in the check code area. When a check code write command is sent, the CRC code for the data in the target calculation area is calculated, and written to the check code area. When the data verification command is sent, the CRC code for the data in the target calculation area is calculated, and compared with the data in the check code area. If these match, the number 75 is returned in the response code to show that the data is normal. If they do not match, the number 76 is returned to show that there is a data error. Example: Memory check is performed when check block header page is 00 and the number of check blocks is 0B. 00 01 ・ ・ ・ 09 0A Check code Calculation area Check code area 3-3-1 Usage After writing the data, calculate and write the check code using the Memory Check Command (MC), and before reading the data, verify the check code using the Memory Calculation Command (MK). You can detect data corruption in advance within the Tags that are not being accessed. Write data Write stage Calculate check code Verify check code Read stage Read data ： This Command is for I.CODE1 Mode Only. The command is not available in ISO mode: 3-6 3-4 Lock Function 3-4 The Lock function protects data from being erased due to unintentional overwriting on the fixed data in the Tags. ■ Lock setting in ISO mode For the lock setting in ISO mode, you can write-protect any given areas by the page of Tag memory. If you execute Write command on a write-protect page, a write processing error (code:79) will occur. You can make the lock setting by executing the Lock command (LK) that enables access to the lock setting area. For the details, see 5-4-7 “Lock Setting: ISO Mode.” ■ Lock setting in I.CODE1 mode There is a lock setting area in the system area of I.CODE1 chip, and you can write-protect any given areas by page. If you execute Write command on the write-protect page, the write processing error (code:71) will occur. The lock setting consists of 12 bits of data in total, giving one bit to each page. Lock setting can be made by using the Lock command (LK). For the details, see 5-5-9 “Lock Setting: I.CODE1 Mode.” ●Lock setting area of I.CODE1 chip: “FDh page” Lock Setting Area b5 Page 04 Page 03 Page 02 Page 01 Page 00 1 byte b4 b3 b2 b1 b0 SNR b6 SNR b7 Write Protect b0 QU IET EAS b1 Family code, application ID b2 Page 05 Page 07 Page 06 b5 Page 08 Page 10 b6 Page 09 b7 1 byte b4 b3 Note: ●The write protection cannot be canceled by the V720-series lock function. Data can never be re-written into write-protected pages; be careful in setting write protection. ●Be extremely careful when setting write protection in the system area. ●Tag-specific codes (UID on I.CODE SLI/SNR on I.CODE1) are write-protected when manufactured. 3-7 3-5 Discriminating Access to Tag Function 3-5 The ID codes set in the Tags are utilized in identifying the target chips in the antenna’s application fields. Responses are returned only when the ID code in the command from the antenna and the ID code on the Tag are matched. The factory default of the Reader/Writer ID codes are all set to 00h, which means communications are available regardless of ID codes on the Tags. ■I.CODE1 mode The I.CODE1 chip has two kinds of one-byte ID codes called the Family Code and Application ID. The Tag ID code can be set/modified by the Write Command (WT) with the Family Code/Application ID area (FF page) specified. The ID codes for the Reader/Writer can be set/modified by the Reader/Writer Family Code Setting (FC)/Reader/Writer Application ID Setting (AI) Command. In I.CODE1 mode No. (1) (2) (3) Reader/Writer set value Family code Application ID 00h 00h 55h 00h 55h AAh No Tag set value Family code Application ID 55h AAh 55h 11h 00h 00h Reader/writer setting (1) This setting enables communication with Tag A, B, and C, as both of the family code and application ID are set to “00h.” Reader/writer setting (2) This setting enables communications with Tag A and B as their family codes match. Communication with Tag C is not possible. This identification code has nothing to do with identifying Tags as the application ID is “00h.” Reader/writer setting (3) The communication with Tag “A” is possible as the family code and application ID match. The communication with Tag B and C are not possible. ■ISO Mode Both the I.CODE SLI and ISO/IEC Chips have a one-byte ID code called AFI (Address Family Identifier). To use this function, the AFI’s must be set for the Reader/Writer and Tags, and the function must be enabled on the Reader/Writer as well. The Tag ID codes are set/modified using the System Write (SW) Command. The ID codes for the Reader/Writer are set by the Reader/Writer AFI Enable/Disable Changeover (AE) Command or the Reader/Writer AFI Value Setting (AF) Command. In ISO mode No. (1) (2) (3) Reader/Writer AFI set value 00h 0Ah 5Ah No. Tag AFI set value 5Ah 0Ah 00h Reader/writer setting (1) This setting enables communication with Tag A, B, and C as AFI is set to “00h.” Reader/writer setting (2) This setting enables communication with Tag A and B of which the AFI’s 4 least significant bits “Ah” match. As the 4 most significant bits are “0h,” the part of this identification code has nothing to do with identifying a Tag. Reader/writer setting (3) The communication with Tag “A” is possible as AFI matches. 3-8 3-6 External I/O Function 3-6 The I/O connector has three external input ports and four external output ports to which such devices as sensors or actuators are connected to build a more efficient system. The external output may be dedicated to the antenna control, depending on the Reader/Writer settings. 3-6-1 External Input [Online Mode] The status can be obtained by the I/O Control Command (CC). Sequenced operations such as those for starting and terminating the communication with Tags by external triggers are available. [Offline Mode] Not available. The I/O Control Command (CC) is rejected. To perform the function, the mode must be switched to the Online Mode by the Stop Command (ST). 3-6-2 External Output [Online Mode] The output status can be modified or read-out by the I/O Control Command (CC.) Read-out data can be evaluated by the host and output as a control signal for Lamps or sounds. When the I/O Automatic Changeover Setting is enabled, the external outputs 3 (OUT3) and 4 (OUT4) are dedicated to the antenna control and thus unmodifiable. However, the output status can be read-out. [Offline Mode] The external output is dedicated to the control from the Reader/Writer in this mode. Modification/Reading out of the output status by the I/O Control Command (CC) is unavailable. The external output 1 (OUT1) is turned ON for a specified period of time (modifiable) when Tags with the uncanceled EAS is detected. The external outputs 3 (OUT3) and 4 (OUT4) are dedicated to antenna control when the I/O Automatic Changeover setting is enabled. 3-9 3-7 EAS Function 3-7 The Reader/Writer supports the EAS (Electronic Article Surveillance) system applied for anti-theft and other devices. The Reader/Writer identifies the unique data string returned by the EAS-bit enabled Tags and detects the existence of the Tags in the communication area. Multiple EAS-bit enabled Tags that exist simultaneously can also be detected. The Reader/Writer stops detecting the Tags by disabling the EAS bit on the Tags. This is useful in preventing unauthorized removal of properties or giving caution. The function operates in either Online Mode, where the function is executed by the commands issued by the connected host, or Offline Mode where the function is executed by the Reader/Writer alone. [Offline Mode] In the Offline Mode, the EAS-bit enabled (non-disabled) Tags are continuously detected. When the EAS-bit enabled Tags enter the Antenna Communication Area and their EAS-response concordance rate exceeds the specified value (=EAS threshold), the external output 1 (OUT1) will turn ON for the specified time. The operation state is visibly identified by the OUT1 LED light. The EAS threshold and external output time are specified by the Offline Mode Setting (FL) Command. ●EAS threshold The Tags return 256-bit fixed data. The concordance rate at which the Tag is recognized as one with non-disabled EAS (EAS-bit disable processing is not performed) is specified by a percentage. The smaller the concordance rate, the more lax the criteria becomes. The initial threshold is 75%. ●The ON-time of the external output 1 (OUT1) The ON-time is specified according to the output time of the lamp or buzzer. The initial output time is 500ms. [Online Mode] The EAS Check (EA) Command is executed from the host. (Refer to SECTION 5-5-10). The EAS-response concordance rate is returned, which is compared to the threshold in the host and evaluated for the existence of the EAS-enabled Tags. ■EAS Setting for the Tag The EAS on the Tag is enabled by a specific command that enables EAS-bit. For the ISO/IEC chip (I.CODE SLI chip), it is done by the System Write (SW) Command and for I.CODE1 chip, it is done by the EAS Setting (ES) Command. 3-10 3-8 Duplicate Communication Protecting Function 3-8 The Duplicate Communication Protecting Function prevents the command that processes multiple Tags serially from performing multiple Read/Write processing for each Tag. This function controls the command so that it performs the processing only once per Tag and returns a single response, even in situations where a Tag is recognized more than once as shown below. The processing load is reduced because the response receiving or duplication check by the host is unnecessary. The communication performance speed is also improved since unnecessary processing is eliminated in the following: 1. The situation where the Tag enters the Antenna Communication Area several times due to its vibration, irregular operation, or stop on the boundary, or because the Tag is in the antenna’s side lobe area. 2. The situation where the Tag is stopped in the boundary zone or enters the Antenna Communication Area several times because of the moved antenna. 3. The situation where the Tag passes an antenna with a discontinuous communication area such as the gate antenna. The enabled function is activated when the commands using the following communication modes are executed: ・FIFO Repeat Mode (FR) ・Multiple Trigger Mode (MT) ・Multiple Repeat Mode (MR, UR[I.CODE1 Only]*) When the function is enabled, the unique number (UID/SNR) given to the processed Tag is recorded in the table of the processed Tags after the command has been executed. When a new Tag is detected and its UID/SNR is obtained, the system refers to the table and processes the Tag only when the UID/SNR is not found in the table. After the Tag has been processed normally, the system records the UID/SNR in the table. The table is initialized at the start of command. * As to UR, the page on which the processing is started must be FB, and the pages must be 2 and more. The function is set by the Duplicate Communication Protecting Function Setting (MX) Command (disabled by factory default.) To enable the function, specify the maximum number of UID/SNRs recorded in the table of the processed Tags. The number of tables can be selected from 1, 4, 8, 16, 64, 128, or 256. Usually, the closest number above the maximum number of Tags that can co-exist in the communication area of the antenna being used is specified. Example) When the maximum number of the co-existing Tags are 6: The number of tables = 8 The table of the processed Tags: 1: Tag０ 2: Tag１ 3: Tag２ 4: Tag３ 5: (Vacant) 6: (Vacant) 7: (Vacant) 8: (Vacant) In this case, Tag 0 is not processed for re-entry in the communication area. When the Tag 4 enters the area it is processed and recorded in row 5: of the table. 3-11 SECTION 4 From Start-up to Operation 4-1 Operation of Reader/Writer ................................................................................. 4-2 4-1-1 Offline Mode..................................................................................................... 4-2 4-1-2 Online Mode ..................................................................................................... 4-3 4-2 Trial Operation ..................................................................................................... 4-4 4-3 Reader/Writer Setting .......................................................................................... 4-5 4-3-1 Host Communications Setting (COM Port Setting) ...................................... 4-5 4-3-2 Chip Operating Mode Setting ......................................................................... 4-6 4-3-3 Command Processing Procedure Setting ....................................................... 4-7 4-3-4 Antenna and Tag Communications Setting ................................................... 4-8 4-3-5 Offline Mode Setting........................................................................................ 4-9 4-3-6 Initialization of settings .................................................................................. 4-9 4-3-7 Fixing of Settings............................................................................................. 4-9 4-4 Installation Environment .................................................................................... 4-10 4-4-1 Installation....................................................................................................... 4-10 4-5 Mounting Method ................................................................................................. 4-11 4-5-1 Mounting Dimensional Drawing .................................................................... 4-11 4-6 Wiring Method...................................................................................................... 4-12 4-6-1 Power Supply and Grounding Wires .............................................................. 4-12 4-6-2 Host Communications Cabling ....................................................................... 4-13 4-6-2-1 RS-232C Interface Cabling.......................................................................... 4-13 4-6-2-2 RS-485 Interface Cabling ............................................................................ 4-15 4-6-3 Assembly of Connector .................................................................................... 4-18 4-6-3-1 Assembly of Host Communications Connector and I/O Connector .......... 4-18 4-1 4-1 Operation of Reader/Writer 4-1 The V720-series RFID system has two operation modes: Offline Mode and Online Mode. The functions and control methods by the host vary, depending on the Operation Mode. One of the two modes must be selected at system setup. 4-1-1 Offline Mode In the Offline Mode, the EAS-enabled Tags (the EAS function mounted on the Tags is not disabled) are always detected (1). When the EAS-enabled Tags enter the antenna communication area, the output results (OUT1) turns ON for the specified time (2). The control from the host is unnecessary. The PCs used for setup are connected as needed when the operating conditions must be specified. Some outputs are exclusively used for antenna control, depending on the settings. During setup with PC Reader/Writer Antenna Tag (1) Setup command (2) Results output Antenna control output Response Communication Radio communication between antenna and tag ●Detecting Tags In the state where the EAS-enabled Tags (the EAS function mounted on the Tags is not disabled), are being detected, the COMM LED flashes in this state. ●Detection of the EAS-enabled Tags In the state where the EAS-enabled Tags are present in the Antenna Communication Area. OUT1 turns ON for the specified time. OUT1 stays ON while the Tags are present in the area. ■LED/Output state in each operating status Item Detecting Tags (EAS) Detection of the EAS-enabled Tags ○:ON, ●:OFF, :Flashing LED state RUN ○ ○ COMM NORM ● ○ Output ERROR ● ● OUT1 OFF ON If an error occurs to the value specified in the EEPROM at power-ON, the status enters the specified-value error state. When this occurs, the factory default value is employed. Note: ●The factory default is Offline Mode. ●To specify Offline Mode operations (Chip Operation Mode, EAS threshold, OUT1 output time, receiving antenna settings, antenna control settings, I/O automatic changeover, etc.), the mode must be switched to Online Mode. ●To switch the Offline Mode to Online Mode, connect the host and execute the Stop Command (ST). ●To switch the operation mode at power-ON, disable the mode by the Offline Mode Setting Command (FL). 4-2 4-1 Operation of Reader/Writer 4-1 4-1-2 Online Mode Communication with Tags (2) is performed according to the command (1) from the connected host. The result is returned to the host as a response (3). The I/O can be read or controlled using commands. The input can be used as a command execution trigger, and the output can be used as a result-based control signal for peripherals. Some outputs are exclusively used for antenna control, depending on the settings. Host device (PC) Reader/writer Antenna （1) Command Tag (2) (3) Response Multipurpose Multipurpose output input (antenna control output) Communication Radio communication between antenna and tag. ●Command Standby State The Command Standby State is where the Reader/Writer is not processing but can accept any command other than AK or NK, which are used for ACK/NACK control. When the Reader/Writer accepts a command, it enters the command processing state. ●Command Processing State When a command is accepted, other commands are ignored until the accepted command has been processed. However, the Stop (ST) and Reset (XZ) Commands are always accepted. When a command that performs continuous processing is executed, the processing state continues until completed or stopped. The COMM LED is lit (flashed) while communication with the Tags is in progress. The Reader/Writer enters a special command processing state in the following situations, although it is not actually communicating with the Tags. The COMM LED is not lit in these cases. ・After the commands have been executed in FIFO trigger or FIFO auto mode FIFO continuation state where the antenna oscillates continuously: Only the FIFO access commands are accepted. ・After the Tag Detection Command has been executed (I.CODE1 Mode only).） Selective state where the simplified numbers of Tags are stored, only the Tag specification commands are accepted. ●Normal/abnormal completion of command processes The NORM LED is turned on when the command from the host has been completed normally, and ERROR LED is turned on if the command has been completed abnormally, for a short period of time at the returning of the response. ■LED/Output state in each operating status Operation state LED state COMM NORM ● ● ○ ● ●／○*2 ○ ●／○*2 ● RUN Command standby ○ Processing with Tags ○ Normal completion of command processing ○ Abnormal completion of command processing ○ ○: ON, ●:OFF, : Flashing , −: Unchanged *1 Specified by I/O Control Command (CC.) *2 Stays lit (flashed) when the communication with Tags is continued.

Section-Item SECTION 4-6 SECTION 4-6 Refer to the Instruction Manual for your antenna. ■ Procedure for Trial Operation Power ON ･Check the voltage and power source terminal connections. ･Check that the Reader/Writer RUN LED is lit. Check the communication between the antenna and Tags with the Host disconnected. Offline Test Online Test using the Host Check the communication between the host and Reader/Writer using the test command. Trial Operation of the System Check the total system operation using the commands. Complete ●Offline test ●Communication test between the Reader/Writer and the host ●Trial Operation of the System Offline Mode is set by the Offline Mode Setting Command (FL). The default mode is set for Offline Mode. By setting the Test Mode, the communications between the Antenna and Tag can be tested without connecting the host. You can exit the Offline Mode by connecting to the host and sending a Stop Command (ST) By using Test Commands(TS), the communications between the Reader/Writer and host can be tested. This test allows the checking of the cable connection and the processing operation of communications before the trial operation of the whole system. It is recommended that RS-232C be connected to COM2 where the communication condition is fixed. ・Prepare a simple communications program on the host and transmit Test Commands. ・If the communications line is normal, the Reader/Writer returns the data received. Check the operation on the real system using the setting commands under the actual operating conditions defined by the system design. When using COM1, the RS-232C cable connection must be modified. :Conduct the test of the final installation positions of both the antenna and Tag after the lapse of standby time (15 minutes). Standby time means the time that elapses after turning the power on to getting the product ready for stable communications 4-4 4-3 Reader/Writer Setting 4-3 The Reader/Writer has been designed for the user to make all the settings by issuing commands from the host. The user can use either the COM1 or COM2 port to make settings. However, we recommend use of the COM2 port because its communications settings have been fixed at factory to survive a power reset. In order to fix the information set for the Reader/Writer to survive a power reset, it is necessary for the user to execute the setting write command (EW) (refer to 10) in 5-７-14 of Section 5). (This does not apply to the communications settings for the COM2 port). 4-3-1 Host Communications Setting (COM Port Setting) Make settings for host communications by using the communications port setting command (CP) Setting name (command name) Baud rate setting *1 (CP command) Data length setting *1 (CP command) Parity bit setting *1 (CP command) Stop bit setting *1 (CP command) BCC bit setting *1 (CP command) ACK/NACK setting *1 (CP command) Timeout setting *1 (CP command) Port Default set value COM1 38400 bps COM2 9600 bps COM1 7bits COM2 7 bits COM1 Even COM2 Even COM1 2bits COM2 2 bits COM1 Enabled COM2 Enabled COM1 No COM2 No COM1 0.5 sec.

None Odd Even This command sets the parity bit for use in communications with the host. 1bit, 2 bits This command sets the stop bit for use in communications with the host. Disabled Enabled No Yes 0.5 sec. 5 sec. This command sets whether the BCC for command frames and response frames for communications with the host will be enabled or disabled. Using the BCC is referred to as "BCC enabled." This command sets whether or not ACK/NACK control is performed between the host and the Reader/Writer. If this control is not performed, it is referred to as "no ACK/NACK control." This command sets the timeout period for ACK/NACK control. This setting will be meaningless unless this command (ACK/NACK control) is set to ON. ：(*1) The communications settings for the COM2 port can also be changed but will return to the Default set values on resetting the power of the Reader/Writer. 4-5 4-3 Reader/Writer Setting 4-3 1) Communications type setting for COM1 port Set whether COM1 will be used as RS-232C or RS-485 by using the communications type setting command (CT) Setting name (command name) Communications type setting *1 (CT command) 2) Node No. setting Default set value RS-232C RS-485 RS-232C If more than one Reader/Writer is connected to a single host, each Reader/Writer needs an ID number so that the host can discriminate one Reader/Writer from another. Such an ID number is called node number. Each Reader/Writer must be assigned a unique node number. Each command or response includes the node number of the Reader/Writer. Communications will not be possible if the node number is wrong. The setting can be saved by executing the setting write command. Use the node number setting command (NM) to set a node number. Setting name (command name) Node No. setting (NM command) 3) Terminal resistance setting Setting range Default set value Setting range 00∼31 00 ：Communications through COM2 are possible regardless of the node number setting. This setting is necessary when COM1 is used as RS-485. If more than one Reader/Writer is connected to a single host, terminal resistance must be turned on for both the host and the Reader/Writer connected to either end of the host in order to ensure stable operation. The setting can be saved by executing the setting write command. Use the terminal resistance setting command (TM) to set the terminal resistance. Setting name (command name) Terminal resistance setting (TM command) Default set value Setting range OFF ON/OFF ： For more information, refer to 4-6-2-2 RS-485 Interface Cabling. 4-3-2 Chip Operating Mode Setting This Reader/Writer consists of 2 types of operating modes (hereinafter called: Operating Mode) in accordance with a type of the Tag (an incorporated IC chip). Both operating modes must be set in accordance with the Tag you choose. Execute the Operating Mode Switch Setting Command (TY).

Use the EEPROM write command (EW) to fix your setting Setting name (command name) EEPROM write (EW command) Precautions on setting modifications ●The execution of the setting commands only modifies the S-RAM (volatile memory) on the Reader/Writer. The modifications are not reflected immediately; they are reflected only after the Reset Command (XZ) has been executed. ●To apply the modified settings at the next startup, fix the settings and reset the power supply. If the settings are not fixed, the modifications will be reset to the original status after the power supply reset. This does not apply to the communication settings for COM2. ●If Reset Command (XZ) is executed without fixing the settings, the settings are reset to original status after the power supply reset. ●The default mode is Offline mode. To change the settings, the mode must be switched to Online mode. Connect the host and execute Stop Command (ST.) 4-9 4-4 Installation Environment 4-4 The V720S-BC5D4 Reader/Writer is a highly reliable control device withstanding tough environments. In order to ensure the full, reliable performance of the RFID system, however, observe the following. 4-4-1 Installation Do not install the Controller under the following conditions. • The ambient temperature is not within a range between -10℃ and 50 ℃ or there are radical temperature changes resulting in condensation. • The humidity is not within a range between 35% and 85%. • There is corrosive gas, flammable gas, dust, salt, or metal powder. • The Reader/Writer is affected by direct vibration or shock. • The Reader/Writer is exposed to direct sunlight. • Oil, or chemical is sprayed onto the Controller. • Do not install the Reader/Writer close to heaters, transformers, or resistors that radiate excessive heat. • If power lines or high-tension lines with large currents are located close to the Reader/Writer, be sure to test the Reader/Writer carefully and make sure that wires connected to the Reader/Writer are not affected by the noise of power lines or high-tension lines. Note ●Be sure to abide by the above before installing the Reader/Writer and carefully test the Reader/Writer. ●Be sure to wire antenna cables separately from other cables. For the antenna cable, be sure to use V720-A41 3.35M or V720-A41 10.33M that is specially designed for this product. Using any other cable may affect adversely the communications performance, waterproof performance, etc. ● For wire power and I/O cables as well, wire them separately wherever possible in order to avoid malfunctions. Caution Ensure that a solid (Class D) grounding is established for the “GR” on the Reader/Writer power connector. 4-10 4-5 Mounting Method 4-5 The Reader/Writer must be mounted using a mounting plate. When mounting, be sure to secure it onto the mounting plate with M6 screws, spring washers and flat washers. Do not apply organic solvent, e.g., screw lock solvent, to the screws to secure the Reader/Writer. If you do, the Reader/Writer body and the mounting plate may be damaged. 4-5-1 Mounting Dimensional Drawing 235.5±0.2 102±0.2 4-M6 or 4-φ6.5 4-11 4-6 Wiring Method 4-6 4-6-1 Power Supply and Grounding Wires ● Power cable Power side Reader/Writer side Connector plug Connected to Name Pin No． 24 VDC + 24 VDC GR FG 0V GND ● Recommended Compact DC Power Supply (OMRON) Model S82K-03024 Output capacitance 24VDC at 1.3A Input voltage 100/200V Attach the ferrite core (accessory) for the cable to supply 100VAC.

When you use the recommended power supply, S82K-03024, and a cable with a thickness of AWG16, the cable can be extended to 7 meters at maximum. If a longer power wire is desirable, use a power supply with remote sensing function. ● The maximum power consumption of the Reader/Writer is 25 W. An inrush current of approximately 30 A at 24 VDC, however, flows when the Reader/Writer is turned ON. Take this into consideration when preparing the power supply. ● Provide a power wire with a thickness of AWG16 in order to prevent the dropping of voltage. It is recommended that twisted-pair wire be used for the power line. The thickness of AWG16 is the maximum wire diameter that can be used with the power connector of the Reader/Writer. ● Use Class D grounding (previous Class 3 grounding) for the Reader/Writer for improved noise resistance. ● Use the ferrite core enclosed to the Reader/ Writer for the 100VAC side of the recommended compact DC power supply S82K-03024. WARNING ● Be sure to connect to a power supply with a maximum power supply capacity of 24V 4.2A (100 W) or less. In case a short-circuit failure should occur within the Reader/Writer, a burnout in the power cable may result. 4-12 4-6 Wiring Method 4-6 4-6-2 Host Communications Cabling 4-6-2-1 RS-232C Interface Cabling V720-HS04 PC RS-232C cable V720-A62 Antenna cable V720-A41 RUN COMM NORM ERROR AC100V RU CO MM NO RM ER RO Power supply S82K-03024 Power supply cable V720-A51 Host computer Reder/Writer (COM1, COM2) Pin layout when cable connector on Reader/Writer is viewed from engaging face FG SG SG SD SD RD RD ＋ − Shield wire Caution ● The shield wire must always be grounded on the host side. ● Leave the pin for RS-485 unconnected. ● Cables must not be longer than 15 meters. 4-13 4-6 Wiring Method 4-6 1) Connection to a DOS/V Host with 9-pin Port (Pin layout when cable connector is viewed from engaging face) Reader/Writer リーダライタ COM1, COM2 SG SD RD ＋ − Connecting 接続機器Device Connector of cable ケーブルに付いたコネクタ DOS/V PC DOS/Vパソコン 9-pin, female 9ピン、メス GR SG SD RD RS CS （シールド線） Shield wire ：Connect the shield wire to the connector cover on the PC side. 2) Connection to Host through NEC 98 or Compatible Computer, 25-pin Port (Pin layout when cable connector is viewed from engaging face) 14 Reader/Writer リーダライタ COM1, COM2 COM1、COM2 13 SG SD RD ＋ − Connecting Device 接続機器 Connector of cable ケーブルに付いたコネクタ 25 NEC98 Compatible PC 98互換パソコン 25-pin, male 25ピン、オス GR SG SD RD RS CS Shield wire （シールド線） 3) Connection to OMRON C200H PLC (Pin layout when cable connector is viewed from engaging face) 1 2 3 Reader/Writer リーダライタ CCOM1, O M 1 、COM2 CO M 2 4-14 SG SD RD ＋ − Connecting Device 接続機器 Connector of cable ケーブルに付いたコネクタ Shield wire （シールド線） C200H ASC02 形 C200H-ASC02 male 9 9-pin, ピン、オス GR SG SD RD RS CS 4-6 Wiring Method 4-6 4-6-2-2 RS-485 Interface Cabling PC RS232C/485 converter V720-HS04 V720-HS04 V720-HS04 Antenna cable Setup V720-A41 ・Node NO. 01 Setup ・Node NO. 00 Setup ・Node NO. 31 ・Terminating resistor OFF ・Terminating resistor OFF RU CO MM NO RM ER RO RS-485 DC24V power supply AC100V ・Terminating resistor ON RU CO MM NO RM ER RO RS-485 connection cable DC24V power supply RU CO MM NO RM ER RO RS-485 connection cable DC24V power supply AC100V AC100V Note On the host side, send the following commands after confirming that the Reader/Writer responds normally.

Be sure to use a twisted-pair wire for the signal line. Be sure to use a wire with a thickness of AWG20 for the signal line. When you use a shielded cable, be sure to ground on the host side. Make sure that the total cable length for 1-to-1 and 1-to-N connection is not longer than 300 m. Note When you connect more than one Reader/Writer, give special attention to communications timing between Reader/Writers. To ensure proper timing, you will need to perform both theoretical calculation of timing and verification of communications on real machines. 1) The Reader/Writers cannot operate simultaneously except through polling-related commands. This means that, even when you connect more than one Reader/Writer, only one Reader/Writer can communicate with the host at a time. Multiple Reader/Writers can access the host only in a time-phased manner. 2) When you use an Auto command, the Reader/Writer will not return a response but continue to wait if there are no Tags in the communications area. In this state, if you send a command to another Reader/Writer, no command will be accepted until a response is returned. To avoid this, you must abort the Auto command using the STOP command before sending any command. 3) Polling-related commands do not support any commands but Auto commands. These commands are not available in Multiple Access Mode (which permits access to multiple Tags) to avoid processing complexities. 4-17 4-6 Wiring Method 4-6 4-6-3 Assembly of Connector 4-6-3-1 Assembly of Host Communications Connector and I/O Connector 1) Disassemble the connector as follows: (1) Loosen the set screw and remove the barrel from the end bell (by turning it counterclockwise).

5-67 5-2 5-1 Control by Commands 5-1 5-1-1 Control by Commands The Reader/Writer operation is controlled by the commands from the connected host. The result of the command execution is returned as a response. In Online Mode, all the operations, such as Tag-data Reading/Writing, Tag-function setting, operating condition setting, or Reader/Writer function control, are controlled by the commands. In Offline Mode, the Reader/Writer functions controlled by the commands are restricted to those controlled by Stop and Reset commands. The operating conditions for Offline Mode are set in Online Mode. Host device (PC) (2) Operation condition setup Command (direction) Reader/Writer Antenna Tag (1) Response (result) Communication with tag General input General output (3) Function control （ functions such as process stop or output setup) 5-1-2 Command-Response Flow In Online Mode, the host sends an instruction command and the Reader/Writer returns the result as a response. The command-response flows vary, depending on the types of commands and specified communications, as shown below. 1-to-1 Response One response is returned per command for Single Trigger (ST), Single Auto (SA), FIFO Trigger (FT), FIFO Auto (FA), UID Select (SL), or Tag Designation is specified for the command that performs the communication with the Tag, or when a command that does not perform the communication with the Tag is specified. Command Host Reader/Writer Response Multiple Response Multiple Responses are returned per command for Single Repeat (SR), FIFO Repeat (FR), Multiple Trigger (MT), Multiple Repeat (MR), or Tag Detection (LT) is specified for the command that performs the communication with the Tag. Host Reader/Writer Command Response Response Response Response No response When the Reader/Writer receives the Reset Command(XZ), it is reset without returning a response and waits for the next command. Host Reader/Writer Command Reset 5-3 5-1 Control by Commands 5-1 5-1-3 ACK/NACK Control When using ACK/NACK control, if the host does not receive a normal response, the Reader/Writer will resend the response by either (1) when the host sends a NACK command to the Reader/Writer or (2) when there is no response within a set period of time. Consequently, a response can be received without communicating with a Tag again. The host checks that responses have been received normally using the ACK/NACK commands, so response data can be communicated dependably. ■Using ACK/NACK Control If the host receives a normal response, it sends an ACK command to the Reader/Writer. The Reader/Writer judges that the host has received a normal response, and enters a command-waiting state. If, after the Reader/Writer has sent the response, an ACK is not received normally within the time set using the time out setting, or a NACK is received, the Retry Flag is set and the last response is sent again. The maximum number of response retries that can be made is nine. Host Receives a Normal Response and Sends ACK Command Host Command ACK Response Reader/Writer Host Cannot Receive a Normal Response and Sends a NACK Command Host Reader/Writer Command NACK Response ACK Response Error occurs Retry Host Did Not Send an ACK/NACK Command within the Timeout Period Host Reader/Writer Command ACK Response Timeout Response Retry 5-4 5-2 Control Procedures for Each Communication 5-2 The operating sequences including the communication with the Tag or timing for returning the response vary, depending on the communication mode. The communication mode is set by specifying the communication mode in the command data. The access and mode specified as the communication settings must be those specifiable for each Tag status in the specified antenna’s communication area or the connection topology with the host. This section describes these access and mode settings. 5-2-1 Single Access In single access, a single Tag can exist in the communications area. The presence of two or more Tags in the communications area causes a communications error. 5-2-1-1 Single Trigger mode Single Trigger mode is used when a single Tag is present in a resting condition in the antenna communication area. If the Tag does not exist in the antenna communication area, No Tag Error is returned.

If a function equivalent to ISO mode, i.e., a function that always returns a response, is required for the area confirmation and other purposes, a single command (Tag code = 0) by Fast Read Access should be used. (If the function is executed in I.CODE1 mode, the Reader/Writer will perform the process only once at the Tag’s entry to the communication area and return a response. Multiple Tags in the communication area may result in a response with abnormal read data). 5-6 5-2 Control Procedures for Each Communication 5-2 5-2-1-4 Polling Auto Read If an Auto command is used when a single host controls more than one Reader/Writer, the communications path between the host and one of the Reader/Writers to which the command is sent becomes busy, disabling the host to control other Reader/Writers. On the other hand, when a Polling Auto command is sent instead, the Reader/Writer returns a response according to the request from the host. The communications line with the host will not remain busy, allowing the host to send a command to other Reader/Writers. When Polling Auto command is executing, the only commands accepted and executed are Polling Check (PC), Polling End (PE), Reset Command (XZ), and Stop Command (ST). An example of Polling Auto Command executed for two Reader/Writer devices are shown below. (Host) (Reader/Writer) (Tag) Polling Auto Command Node 1 (1) The host sends the Polling Auto Command to the Node 1 Reader/Writer. Response (2) Immediately after command reception, Node 1 returns a response indicating the acceptance of the command. Polling Auto Command Node 2 Polling subcommand Referring to Node 1 Polling subcommand Referring to Node 2 Response Yet to enter Node 2 Response pass Node 1 Yet to enter. Response Yet to enter Node 2 Yet to enter Response Node 1 Polling subcommand Referring to Node 1 Tag(2) Passing in front of Node 1’s antenna (3) The host sends the Polling Auto Command to Node 2. (4) Immediately after command reception, Node 2 returns a response indicating acceptance of the command. (5) The host inquires after the progress of the communications processing or stops the Polling Auto processing using the Polling sub command. When the communications processing is not yet complete, the Reader/Writer returns a response indicating unfinished processing in reply to the inquiry of the Polling sub command. (6) The Node 1 communicates with a Tag entering the communications area. Response Communications processing by Node 1 is complete. (7) Node 1 returns a response indicating the results of communications with the Tag in reply to the Polling subcommand. 5-7 5-2 Control Procedures for Each Communication 5-2 5-2-2 FIFO Access In FIFO (first-in, first-out) access, communications with Tags entering the communications area one after another are carried out in sequence. Once communications with Tags are completed, access to them is prohibited. Consequently, even if Tags with which communications are already completed exist in the communications area, a newly entering Tag can be accessed. Simultaneous entering of two or more Tags causes a communications error. Once an access-prohibited Tag leaves the communications area, access to the Tag is enabled again. 5-2-2-1 FIFO Trigger Mode FIFO Trigger Mode is used for communications when the Tag is present in a resting condition in the antenna communication area. The Reader/Writer prohibits access to the Tag after the communication has been completed, and keeps the antenna oscillated to maintain the FIFO access. Under such conditions, the Reader/Writer can issue another FIFO command and communicate with the next Tag that enteres the communication area, where the previous Tag with which the communication has been completed is still present. (The commands other than FIFO Access are rejected). When there are no accessible Tags in the antenna communication area, the No Tag Error is returned.To exit the FIFO state, execute Stop Command (ST).

The Reader/Writer prohibits access to the Tag after the communication has been completed, and keeps the antenna oscillated to maintain the FIFO access. Under such conditions, the Reader/Writer can issue another FIFO command and communicate with the next Tag that entered the communication area where the previous Tag with which the communication has been completed is still present. (The commands other than FIFO Access are rejected). When the Reader/Writer receives Auto Command, it enters the busy state until the communication with the Tag has been completed, during which it does not accept any commands other than Stop Command (ST) and Reset Command (XZ).

FIFO access is maintained. Note: Note, that in Auto mode, the communication path between the Reader/Writer and the host are busy until the Tag is close to the area; the host cannot send the next command under such conditions. 5-9 5-2 Control Procedures for Each Communication 5-2 5-2-2-3 FIFO Repeat Mode The Reader/Writer waits until the Tag has entered the antenna communication area and starts communicating. It communicates with the Tags serially as they enter the antenna communication area, and returns the responses. When the communication has been completed, the Reader/Writer makes the Tag inaccessible, so that it can communicate with the next Tag that entered the area although the Tags with which the Reader/Writer has completed the communication are still present in the same area. This state continues until the communication has been terminated by Stop Command (ST), or Reset Command (XZ), and other commands are rejected. （上位機器） (Host) （リーダライタ） (Reader/Writer) （タグ） (Tag) Waits forタグ接近待ち a Tag to approach Yet to 未接近 approach Waits forタグ接近待ち a Tag to approach Yet to 未接近 approach 交信処理 process Communication タグ（1） Tag (1) リピートコマンド Repeat Command ビジー状態 Busy (1) Waits for a Tag to enter the ①R/W アンテナの交信領域内にタグが入る Reader/Writer antenna のを待ちます。 communication area. ビジー状態 Busy レスポンス Response 通過 Passes レスポンス受信 Receives a response (2)When a Tag enters the Reader/Writer R/W アンテナの交信領域内に入る ②タグがcommunication antenna area, the とリーダライタはタグと交信を行います。 Reader/Writer communicates with the Tag. ③交信が終了するとレスポンスを返信しま (3)When the communication has been completed, the す。 Reader/Writer returns a response.

In this case, enable the Duplicate Communication Protecting Function (Table number = 1). The function will prevent the Reader/Writer from communicating with the Tags already communicated with, and allows proper and sequential Tag processing.［Software Ver 1.20 and higher only］ Note To send another command from Repeat Mode, be sure to use either the stop command or reset command, and make sure that the Reader/Writer has finished processing commands and is in command waiting status before sending the new command. 5-10 5-2 Control Procedures for Each Communication 5-2 5-2-3 Multiple Access In Multiple Access, the Reader/Writer can communicate with all of the multiple Tags present in the antenna communication area. In I.CODE1 Mode, the Tag code corresponding to the number of Tags present in the communication area must be specified. For the Tag number specifications, refer to SECTION 5-2-5. When the Tag is on the boundary of the communication area or enters the communication area more than once because of swing, the normal operation may be interrupted because the Tags are processed more than once. In this case, it is recommended that UID/SNR addition setting be enabled to evaluate the Tags on the host side. In addition, one processing per Tag is available by enabling the Duplicate Communication Protecting Function. For Duplicate Communication Protecting Function,, refer to SECTION 3-8. 5-2-3-1 Multiple Trigger Mode Read Command (RD) Write Command (WT) with UID/SNR addition setting enabled (Excluding I.CODE1 Mode). At the reception of the command, the Reader/Writer communicates with all the Tags in the communication area and returns communication results with each Tag, as responses. After communicating with all the Tags, it returns Detection End Response (Response Code: 72). When no Tag is present in the communication area, it returns to Detection End Response (Response Code: 72).

At the completion of communicating with all the Tags, it returns Detection End Response (Response Code: 00) once. The number of Tags with which the communication has been normally completed is added to Detection End Response. When no Tag is present in the communication area, it returns Detection End Response (Response Code: 72).

At the completion of communicating with all the detected Tags, it returns the Detection End Response and terminates the command processing. In I.CODE1 Mode, the Response Code is set to 00 only after the communications with all the detected Tags have been completed successfully. When the number of Tags detected exceeds the number specified by the Tag code in command data, the Response Code is replaced with a warning code (Code: 0□), (Refer to SECTION 5-3-7). If data writing process in even one Tag has failed, the Reader/Writer returns to Write Process Error (Response code: 71), and terminates the command processing. Note: In processing Multi-Trigger Command, some Tags may not be processed due to their conditions (including the distances between the antenna and Tag, or those between the Tag and another Tag). The operating system must be configured to check the number of processed Tags based on the number of returned responses or normally processed Tags, and match them against the actual number of the Tags. 5-12 5-2 Control Procedures for Each Communication 5-2 5-2-3-2 Multiple Repeat Mode Read Command (RD) Write Command (WT) with UID/SNR addition setting enabled (Excluding I.CODE1 Mode).

However, the operation may become highly complicated, depending on the Tag status. 5-13 5-2 Control Procedures for Each Communication 5-2 5-2-4 Selective Access Selective Access is a function to communicate with the specified Tags among multiple Tags in the antenna communication area. The processes vary depending on the Reader/Writer’s mode. 5-2-4-1 ISO Mode First, the Reader/Writer reads out the UID of the Tag in the communication area using Read Command (in multiple processing modes). The UID is readable when UID/SNR addition setting option is enabled in advance using the respective command (SN). When the UID is already identified, the execution of Read Command can be skipped. Then, the Reader/Writer communicates with the specified Tag based on the obtained UID. (1) The Reader/Writer reads the UID of the Tag using Read Command. It reads out UID data of the Tag by executing a Multiple Trigger Mode command with its UID/SNR addition setting enabled. (2) The Reader/Writer communicates with the specified Tag (No. 2 in the figure below) by specifying the UID obtained in 1 using UID Select Read/Write command. The ReaderWriter communicates with the Tag specified by the UID. For UID Select Command, specify SL for the communication, and specify the UID of the communication target Tag in the UID area in hex number, 123. Note: Some Tags detected by UID read (Tag detection) may not be communicated with Selective Access mode using UID Select (Tag designation) command, depending on the Tag conditions (the distances between the antenna and tag, or those between the Tag and another Tag). This is especially true when the Tag exists in the boundary area of the communication area. The operating system must be configured to check the number of detected Tags against the number of Tags the Reader/Writer communicated with (or the number of the actual Tags). 5-14 5-2 Control Procedures for Each Communication 5-2 ■Selective Access Operation: In ISO Mode (Host) (Reader/Writer) (Tag) (1) The Reader/Write receives a command.

The Tag code must be specified as command data according to the numbers of the Tags present in the communication area. For Tag number specifications, refer to SECTION 52-5. 1. Numbers are allocated to the Tags by Tag Detection Command. Tag Detection Command, the state enters the Select State, where the mapping of the Tags in the antenna communication area and their Temporary numbers are stored. In Select State, all the commands are rejected except the Tag Designation Command. The Select State is valid until Stop Command (ST) has been executed. 2. After allocating the numbers to the Tags, the Reader/Writer communicates with the specified Tag (No.2 in the figure below) using Tag Designation Command. The ReaderWriter communicates with the Tag specified by the Temporary number. It can communicate with the Tags repeatedly in the Select State. Tag Detection Command/Tag Designation Command For Tag Detection Command, specify LT as the communication method of the command. For Tag Designation Command, specify 00 to 7F as the communication method of the command.

This setting must be set according to the number of Tags with which to communicate simultaneously. Refer to the table below for the relationship between the number of Tags and this setting. Specifying a Tag Code Max. No. of Tags with which simultaneous communication is possible ∼2 ∼4 ∼8 ∼16 ∼32 ∼64 ∼128 Example: If the number of Tags is seven, select Tag Number setting 3. Note: ● For the Multi Trigger(MT) and the Multi Read(MR), if more Tags than have been set using the timeslot setting enter the communications range, a "70" error (warning) may occur. (e.g., When the timeslot setting is "2" and there are five Tags in the communications area.) ●For the Special Read (refer to 5-2-1-6) command, the anti-collision process is not performed. Therefore, read data will be returned even If there are more Tags than the timeslot setting in the communications area.If a collision occurs, such data will not be returned. ● The higher the timeslot setting is, the longer the communications time is required. Consequently, setting a higher timeslot setting than required for the number of Tags in use unnecessarily lengthens communications time, so select a suitable setting. 5-18 5-3 Command-Response Format 5-3 5-3-1 Command Frame Structure The Reader/Writer continuously receives signals from STX through ETX, and executes the command when the correct node number is received (*1).

The host communications time varies depending on the communications settings and the codes that you specify. Example of calculation: when operating in Single Access Mode and Trigger Mode to read 1 page (4 bytes) data ■Code-specified in ASCII: The total number of characters is 29, i.e., 15 characters in the command part and 14 characters in the response part. From this, the host communications time would be 29 * 11 bits /38400(bps) * 1000 = 8.3 (ms). The communications time would be14 ms for Fast Mode and 92.9 ms for Standard Mode. TAT, therefore, would be 8.3 + 14 = 22.3 ms for Fast Mode and 8.3 + 92.9 = 101.2 ms for Standard Mode. ■Code-specified in HEX: The total number of characters is 33, i.e., 15 characters in the command part and 18 characters in the response part. From this, the host communications time would be 33 * 11 bits /38400(bps) * 1000 = 9.5 (ms). The communications time would be14 ms for Fast Mode and 92.9 ms for Standard Mode. TAT, therefore, would be 9.4 + 14 = 23.5 ms for Fast Mode and 9.4 + 92.9 = 102.4 ms for Standard Mode. ： ・ The provided TAT graph data shows an example in which the V720S-BC5D4 Controller is used with the following communications specifications for host communications: The data is continuously sent with no space between characters, at a baud rate of 38,400 bps, in a data length of 7 bits with 1 start bit, 2 stop bits and even parity. 7-5 7-2 Calculating the speed of the Tag 7-2 When communicating with a Tag in motion, select Auto or Repeat for the communications method. The maximum speed at which the Tag can travel can be obtained easily, using the formula below. Max. traveling speed = D (travel distance in communications area) T (communications time) x Safety factor (0.5) Calculate D from the communications area drawing between the Antenna and the Tag or from the actual measurement. Communications area Direction of travel ：The formula above is for communications with one Tag. Be sure to check the traveling speed of multiple Tags in advance. Notes on the passing speed evaluation: 1） As a precaution to ensure minimal noise, the Reader/Writer performs retransmission tests in the event of a communication error between the Tag and antenna. Since the transmission time is dependent on the noise conditions in each environment, a transmission test using the actual device must be conducted in advance. The calculation formula for the communication time does not assume retransmission. 2） The calculation formula above assumes the communication Tags in transit must be tested in advance.
