Correct Usage 1. Do not install model V690-HMG01, model V690-D8KR01 and model V690-L01 in the following areas: • Place exposed to the direct sunlight. • Humid place where moisture condensation may occur. • Place affected by vibration or impact. 2. Preliminary check of installation site. This device uses the frequency band 2450 MHz for the communication between an antenna and tag. Some of radio equipment, such as wireless LAN, cellular phone, personal handyphone system and transceiver, motor and switching power supply may generate a radio wave (noise) which affects the communication with a tag. If you must use this device near such heater, we would like to ask you to check the influence in advance. To minimize general influence of noise, follow the instructions below: • Ground any metallic material located around this device according to Class D (Class III). • Wire this device keeping away from high voltage and heavy current. 3. Ambient environment and communication range • The communication range varies depending on the installation site environment. This is because a metal material and the ground reflect a radio wave, and water and human body absorb it. Locate an antenna and tag in the communication range and check the radio wave environment in advance. • The Read/Write antenna model V690-HMG01 has a communication test command to check the radio wave environment at a working site. (Refer to Section 3-5.) 4. Be sure to ground any ground terminal according to Class D (conventional Class III). Otherwise, performance may deteriorate. 5.

(Refer to Section 5-9-7.) 2-11 Chapter 3 Functions 3-1 Single/FIFO/Multi Mode Access Function You can use one of the three communication modes according to the number of tags in the communication area and the situation. The communication mode can be specified in the communication designation in a command. (1) Single mode In the Single mode, the communication is made to one tag in the antenna communication area. In the Single mode, only one tag must be placed in the antenna communication area. If two or more tags are in the antenna communication area, a communication error occurs. (2) FIFO mode (First-In First-Out) The FIFO mode enables to access the tags coming in the communication area sequentially one by one. When the communication to one tag has been completed, the tag is prohibited from communicating. So, even if there is any tag, which ended the communication, in the antenna communication area, the communication can be made to the next target tag. When the tag prohibited from communicating has gone out of the antenna communication area, such tag can communicate again. (3) Multi mode When there are several tags in the antenna communication area, the Multi mode enables to access all those tags. By using the Selective Access function, the communication can be made to a specified tag of those in the antenna communication area. Correct Usage When you use the FIFO mode, only one tag must be placed in the antenna communication area. If two or more tags are in the antenna communication area, a communication error occurs. Then, the communication cannot be recovered from failure unless only one tag is in the antenna communication area. 3-1 3-2 Communication 2 m Mode/5 m Mode Switching The communication 2 m mode and 5 m mode can be switched to each other by a command from a host device. Use either one depending on a working site. For the command, refer to Sections 5-9-2 and 5-9-3. The default value is the 2 m mode. For the communication area of 2 m mode and 5 m mode, refer to Section 7-1. 3-2 3-3 Radio Wave Channel Switching In this RFID system, a range from 2437.5 to 2462.5 MHz in the 2450 MHz frequency band can be divided into ten, and 10 channels (at 2.5-MHz intervals) are available. Those channels can be switched by a command from a host device. Use them to prevent the mutual interference between antennas or interference caused by any other devices. For the command, refer to Sections 5-9-2 and 5-9-3. The default value is Channel 5 (2450 MHz). Channel 2450 MHz frequency band Correct Usage Due to dispersion of frequency, the frequencies of adjacent channels may overlap each other. Do not assign consecutive numbers to the channels of adjacent antennas. 3-3 3-4 Simplified Communication Test You can check the communication between an antenna and tag using the antenna only without connecting to a host device. In the simplified communication test, the antenna detects the tag at approximately every 2 seconds and, if the tag responds, it turns on the indicator C. (1) (2) (3) (4) Turn off the power supply. Short-circuit the setting terminals "+P" and "-P". Turn on the power supply. Then, the setting mode is enabled. (Refer to Section 5-1.) The simplified communication test starts. As shown below, the indicator C (Radio wave emission) shows whether the communication to the tag is made successfully. (5) When any command has been sent from a host device to the antenna, the communication test stops. Antenna Indicator (Red) Power supply Radio wave emission Host transmission Tag transmission Indication C and T blink at approximately every 2 seconds. This shows that there is no tag. C turns on ( ). This shows that there is a tag in the antenna communication area. : Turns on. 3-4 : Blinks at approximately every 2 seconds. (This shows that data is being sent.) : Turns off. 3-5 Communication Test Execute the communication test to check a radio wave environment at a working site. Data (256 bytes) is communicated 256 times between the antenna and tag and the communication status is output. A total of 128 kbytes of data is communicated in two ways. So, it takes a few seconds to execute this test. The communication is not retried. Refer to Section 5-7-8. (1) (2) (3) (4) (5) (6) (7) Create a communication program at a host device. Enable the operation mode. (Disconnect the terminals "+P" and "-P" from each other. Refer to Section 5-1.) Turn on the power supply. Put the tag in front of the antenna. Send a communication test command (Section 5-7-8). If the antenna is 00, the command is [STX]0080T0SU[ETX]. If the antenna responds to the host device, the communication between the host device and antenna has been made successfully. In the response [STX]8000T0000256 [ETX], a radio wave environment value is between 0000 and 0256. If the value is close to 0000, the communication to the tag is stable. Example of response from antenna: * Radio wave environment is good. [ STX] 8 0 0 0 T 0 0 0 0 2 5 6 0 0 0 0 [ ETX ] Number of Radio wave communications environment value * Radio wave environment is poor or no tag is in communication area. [ STX] 8 0 0 0 T 0 0 0 0 2 5 6 0 2 5 6 [ ETX ] Number of Radio wave communications environment value Correct Usage We recommend you to set the radio wave environment value to 50 or less. 3-5 3-6 Write Protect Function You can enable Write Protect for user data (8 kbytes) per page (256 bytes). Write Protect allows to prevent data being destroyed by authorized writing. ♦ Scope of Write Protect The addresses of pages from P0 to P31 are described below. Page 256 Bytes/page P0 0000-00FF (h) P1 0100-01FF (h) P2 0200-02FF (h) P30 1E00-1EFF (h) P31 1F00-1FFF (h) 256 Bytes x 32 pages = 8192 bytes * (h) means that the value is a hexadecimal number. ♦ How to enable Write Protect 32 Bits of Write Protect data (4 bytes) of system data (refer to Section 2-2-3) correspond to each page. By rewriting a bit corresponding to a write-protected page from 0 (disable) into 1 (enable), Write Protect to the page is enabled. To disable Write Protect, rewrite the bit from 1 into 0. Relation between bit of write-protected data and page is described below. Write-Protected Data (4 Bytes) Code Bit A1 P7 P6 P5 P4 P3 P2 P1 P0 A2 P15 P14 P13 P12 P11 P10 P9 P8 A3 P23 P22 P21 P20 P19 P18 P17 P16 A4 P31 P30 P29 P28 P27 P26 P25 P24 P**: Status of Write Protect in page ** (between 0 and 31). 3-6 Description Status of Write Protect 0: Disabled (Default value) 1: Enabled 3-6 Write Protect Function ♦ Example of enabling/disabling Write Protect (1) Enable Write Protect to P3 and P14 in the initial state of the ID tag.

Write-protected data is as follows: Decimal notation Hexadecimal notation An example of the Write command (Section 5-7-4) is as follows: Command code Communication designation Split flag Data designation 3-7 3-7 ID Tag Power-Saving Function The tag has the two power-saving functions below. ♦ Function to prevent battery power loss due to radio wave emitted from any other radio equipment (Enabled always) If any radio equipment is located near a tag, the tag operates (ready to operate) because the tag’s receiving band is wide. As a result, the tag battery may be consumed. (Refer to "Notes on Interference to Second-Generation Low-Power Data Communication System (Wireless LAN), Cellular Phone, etc." at the beginning of this manual.) To prevent this power loss, the tag has a function to enter a sleep state (refer to "Appendix 1 - Glossary") against a radio wave emitted from any other radio equipment. • The V690 antenna sends a wake instruction (refer to "Appendix 1 - Glossary") at every 100 msec after emitting a radio wave and the tag operates (ready to operate). • When the tag receives a radio wave emitted from any other radio equipment, the tag may operate (ready to operate). However, unless receiving a valid wake instruction, the tag returns to a sleep state in 2 seconds. Wake instruction Antenna radio wave emission Even if there is no command from a host device, the antenna sends a wake instruction at every 100 msec while emitting a radio wave. Operates (Ready to operate) Tag Sleep 2 seconds (fixed) If the tag once receives a valid wake instruction in 2 seconds after it started an operation, the tag does not sleep. Operates (Ready to operate) Tag Sleep 2 seconds (fixed) If the tag cannot receive a valid wake instruction in 2 seconds after it started an operation, the tag sleeps. 3-8 3-7 ID Tag Power-Saving Function ♦ Function to prevent battery power loss due to neglect when tag works (Enabled always) When you use the antenna with a repeat command (refer to (3) in Section 5-2-1), due to a trouble in a working site, the tag may be left in front of the antenna which is emitting a radio wave, although the tag operates (ready to operate). Then, the tag battery is consumed. To prevent this power loss, the tag has a function to enter a sleep state when a waiting time for sleep (refer to a chart below) has passed. If the tag cannot receive a valid command within a waiting time for sleep after receiving a valid command, the tag enters a sleep state. A default value of waiting time for sleep is 480 seconds (8 minutes). To change waiting time, specify "SLEP" as address in the Read/ Write command. (Refer to Sections 5-7-1 and 5-7-3 to 5-7-5.) To recover the tag from the sleep state: • Turn OFF the power supply transmission of the antenna and turn ON it again. • Take the tag out of the communication area and place it in the communication area again. Antenna radio wave emission (A radio wave is being emitted) Command process Tag Operates (Ready to operate) Sleep Waiting time for sleep 3-9 Chapter 4 Installation and Connection 4-1 Read/Write Antenna and ID Tag 4-1-1 Installation Environment (1) Antenna and tag Install the antenna and tag so that those front faces can face each other. Confirm the front side and the reverse side of them. The front faces must face each other. Tag Antenna Front face Front face (2) Antennas Keep sufficient space between the antennas according to Section 7-5. If sufficient space cannot be obtained: • Assign the most different channel numbers to the radio channels of adjacent antennas. (Refer to Section 3-3.) • Permit only one of antennas to transmit a radio wave so that those antennas do not transmit radio waves simultaneously. (3) Tag rotating position to antenna The antenna and tag use "circularly polarized wave" as radio wave to communicate with each other. So, the tag can communicate with the antenna at any rotating angle. The maximum communication range varies depending on the rotating angle of the tag. Refer to Section 7-3. • Conceptual diagram of circularly polarized wave The arrows show the directions of vibrating surface. The radio wave propagates while the vibrating surface is rotating. Tag Antenna * A hatched area on the tag shows the "omron" logo. 4-1 4-1 Read/Write Antenna and ID Tag (4) Influence of external objects • Radio wave absorbers: water, human body, water screen, water-absorptive material, etc. A radio wave (microwave) penetrates anything (solid body and liquid) other than metal, but it is attenuated while penetrating. In particular, water absorbs a radio wave extremely. When a radio wave penetrates the water, the radio wave is absorbed considerably. Also, the radio wave is attenuated remarkably in a human body which contains much water. So, any solid body and liquid must not exist between the antenna and tag. A general-purpose plastic plate with thickness of or glass plate a few millimeters does not absorb the radio wave, and the radio wave attenuation is not a serious problem in this case. However, the radio wave attenuation varies depending on a type of material and/or thickness of external objects which the radio wave penetrates. Execute the communication experiment in a working site in advance. When the communication is performed through the plastic plate or glass plate which absorbs the radio wave so much, such plastic plate or glass plate may be covered with water due to rain. The radio wave may be attenuated by this water screen and the communication may fail. Execute the communication experiment in a working site in advance and take great care not to get out of the communication range during an operation. Dry wood and paper do not attenuate the radio wave so much. However, wood and paper absorb water easily. The wet wood and paper may attenuate the radio wave considerably. Execute the communication experiment in a working site in advance using both of dry materials and wet ones. A part of radio wave is reflected. Radio wave transmitted from an antenna Object Absorbed in an object and attenuated. Tag Radio wave transmitted from a tag. • Radio wave reflectors: metal, ground, etc. Metal reflects a radio wave (microwave) like a mirror reflects light. If there is a metal near an antenna communication area, the communication area is affected by the metal. If a metal is put between an antenna and tag, the communication between the antenna and tag may fail. Metal, whether metal plate or wire netting, may affect the communication. Also, the ground affects the communication like metal. As shown below, a radio wave absorber or reflector can be used to interrupt a radio wave. When you interrupt the radio wave, execute the communication experiment in a working site in advance. Example of radio wave absorber: ECCOSORB AN75 (61 x 61 cm, E&C Engineering) Incoming Outgoing Communication area Radio wave interrupt Antenna Tag that you want to process data Tag that you do not want to process data 4-2 4-1 Read/Write Antenna and ID Tag • Communication area affected by the ground If an antenna is installed near the ground, radio waves (microwave) emitted from the antenna and ones reflected by the ground overlap each other. Therefore, an outline of the communication area becomes ragged and complex. In this case, dead zones may be formed frequently, where no communication can be made to the tag. Antenna Tag Ground Communication area affected by the ground Tag Communication area not affected by the ground Antenna Ground Correct Usage Depending on a working site, a special point may be generated in the communication area above and the communication to the tag cannot be made at the point. So, be sure to execute the communication check with a communication test (refer to Section 3-5), etc. 4-3 4-1 Read/Write Antenna and ID Tag (5) Installation environment Do not install the antenna and tag at any place below: • Place where the ambient temperature is out of the range between -20 and +60°C for the antenna and -25 and +70°C for the tag, where the temperature fluctuates considerably and where moisture condensation occurs frequently. • Place where the relative humidity is out of the range between 35 and 85%RH. • Place where there is corrosive gas, flammable gas, dust, salt or iron powder. • Place affected by vibration or impact. • Place splashed with water, oil or chemicals 4-1-2 How to Install Antenna Install an antenna on a flat plane taking care not to bend it by force. As shown below, mount the antenna with four M5 screws, spring washers and flat washers. Tightening torque is 2.0 N•m (approximately 20 kgf•cm). Do not use any lock paint to fix screws. Spring washer Flat washer (Unit: mm) Correct Usage Do not disassemble it nor touch the inside when the power supply turns on. Otherwise, trouble may be caused. 4-4 4-1 Read/Write Antenna and ID Tag 4-1-3 Rainproofing of Antenna The antenna is not waterproof structure. So, do not install the antenna. If you must install the antenna outdoors, protect the antenna against rain with a plastic rainproof box. To prevent the water droplet coming in the antenna through a cable, be sure to turn the antenna cable section downward. Example of plastic rainproof box: Model WB-5AJ (Outside dimensions: 571 (H) x 412 (W) x 210 (D) mm, Mirai Industry) Gap between the antenna surface and window plate is 10 to 20 mm. Example of protection box Cover the window with an acrylic plate, etc. 3 mm in thickness which a radio wave can penetrate easily. Size enough to cover the entire antenna including a connector. If the box is metallic, make a window on the box. The window size shall be the same as the antenna. Drill a large hole for ventilation and drainage. Clamp it to prevent the connector being pulled directly. Correct Usage Protective structure IP62 of the antenna is the protection against the drop of water. If the antenna is splashed with water spray or water jet flow, cover the antenna with a protection plate. (Refer to "Appendix 3 - Protective Structure".) 4-5 4-1 Read/Write Antenna and ID Tag 4-1-4 How to Install Tag ♦ Installation Install a tag on a flat plane taking care not to bend it by force. As shown below, mount the antenna with two M4 screws, spring washers and flat washers. Tightening torque is 1.2 N•m (approximately 12 kgf•cm). Do not use any lock paint to fix screws. Spring washer Flat washer (Unit: mm) ♦ Influence on communication performance, adhesive, metal tape, water screen, etc. • When you apply adhesive, etc. on the tag surface, a radio wave (microwave) is attenuated and the communication area may be affected. Execute the communication experiment with anything used actually in advance. • If a metallic tape, etc. is put on the tag surface, a radio wave is interrupted and the communication to the antenna fails. • If the tag is put on a glass plate with double-sided adhesive tape as shown below, a gap between the glass plate and tag sweats easily. Moreover, a water screen may be generated. In this case, please note that a radio wave is absorbed and the communication range may become small. Double-sided adhesive tape, etc. ID tag Glass plate, etc. 4-6 4-1 Read/Write Antenna and ID Tag 4-1-5 How to Connect Connecting Cable to Antenna To connect an antenna and host device, use a connecting cable (unbundled). RS-232C connecting cable V690-A4! * Refer to Section 2-4. RS-422A/485 link unit connecting cable V690-A5! * Refer to Section 2-4. (1) When you connect a connector of dedicated cable and connector of antenna, be sure to hold those connectors and insert them into each other completely. (2) When you have connected the connectors, turn a ring completely as shown below. Antenna side Dedicated cable Ring Correct Usage • Do not connect nor disconnect the connectors when the power supply turns on. Otherwise, a trouble is caused. • Do not pull the cable by force. • Do not touch a connecting terminal of the connector. • Do not touch the connector during an operation. 4-7 4-2 How to Wire to Host Device 4-2-1 How to Wire RS-232C Interface (1) Using RS-232C connecting cable To connect an antenna and IBM PC compatible machine, use a dedicated RS-232C connecting cable model V690-A4!.

Host Device Communication line ID Tag Read/Write antenna Command Communication between the antenna and tag Response ♦ Operation mode and setting mode of antenna Two modes are available in the operation of antenna. Available commands vary depending on the mode. Refer to Section 5-4. Host communication Antenna Mode How to change mode Description condition station number Operation mode Setting mode Disconnect the two antenna terminals "+P" and "-P" and reset the power supply (turn off the power supply once and turn on it again). Use for a normal operation. Setting can be changed. (Refer to Section 5-97.) 00 to 31 (Initial value 00) Short-circuit the two antenna terminals "+P" and "-P" and reset the power supply. • A simplified communication function (without connection to a host device) is available. Refer to Section 3-4. • A tag communication command and radio wave transmission ON/ OFF command cannot be used. Fixed. (Refer to Section 5-97.) Use when the host communication condition is unknown. 99 ♦ Tag status after a command has been executed Two modes are available after a command has been executed. Mode How to change mode Description Sleep state Specify S! or R! in communication designation with a command. • Tag battery power can be saved. • A tag cannot be started in 0.2 seconds immediately after sleep. • Use for FIFO (First-In First-Out). Refer to (3) of Section 5-2-1. Standby state Specify W! or C! in communication designation with a command. • Use when several commands are executed consecutively to one tag. 5-1 5-2 Communication Operation Sequence Operation sequence, such as communication to a tag and response return timing, varies depending on the designation with a command. You need to use properly according to the tag status in an antenna communication area and a type of communication with a host device. 5-2-1 Communication Mode with Command (1) Trigger Communication is performed to a tag in an antenna communication area when a command has been received. Therefore, check that the tag is in the antenna communication area and then execute a command. If there is no tag in the antenna communication area when a command has been executed, the antenna returns an error response. When a command is executed, the tag is in a sleep mode or standby mode. • Sleep mode (Communication designation SU or SN) The tag battery power can be saved in the sleep mode. The tag cannot be started in 0.2 seconds immediately after sleep. • Standby mode (Communication designation WU or WN) To execute several commands consecutively to one tag, enable the standby mode. (Host device) (Antenna) (Tag) Not yet approached Trigger command (1)The host device must check that the tag is in the antenna communication area and then execute a command. Tag Communication process (2)The antenna communicates to the tag according to the command. Tag Sleep or standby Response Command process ended Correct Usage Trigger, check that a tag is in the antenna communication area. 5-2 (3)When the process has completed, the antenna returns a response of the process end to the host device and becomes ready to accept a command. 5-2 Communication Operation Sequence (2) Single Auto An antenna waits until a tag approaches the communication area and then communicates with the tag. To terminate Single Auto: • When an auto repeat cancel command (C2) is issued, the antenna discontinues Single Auto and becomes ready to accept a command. • When any other command is issued, the antenna discontinues Single Auto and executes the new command. If the command format is wrong, the antenna returns the format error response 14 and discontinues Single Auto. • If a waiting time for tag (refer to Section 5-9-4) is set, when the waiting time for tag has been passed, the antenna returns the no-tag error response 72 and discontinues Single Auto. When a command is executed, the tag is in a sleep mode or standby mode. • Sleep mode (Communication designation SU or SN) The tag battery power can be saved in the sleep mode. The tag cannot be started in 0.2 seconds immediately after sleep. • Standby mode (Communication designation WU or WN) To execute several commands consecutively to one tag, enable the standby mode. (Host device) (Antenna) (Tag) Single Auto command Waits for tag approaching Not yet approached Waits for tag approaching Not yet approached Communication process Tag Sleep or standby (1)The Single Auto command is sent from the host device. (2)The antenna does not return a response until the tag approaches. So, the host device waits for a response. (3)When the tag passes the front of the antenna, the antenna communicates with the tag according to a command. Response Command process ended Pass (4)When the process has completed, the controller returns a response of the process end to the host device and becomes ready to accept a command. 5-3 5-2 Communication Operation Sequence (3) Repeat When an antenna receives a command from a host device, the antenna waits for tag approaching, communicates with the tag whenever the tag passes the antenna communication area, and returns a response to the host device. After the command is executed, by specifying the sleep state (S!) as the communication designation, FIFO (First-In First-Out. Refer to Section 3-1) is enabled. To terminate repeat state: • When an auto repeat cancel command (C2) is issued, the antenna discontinues Repeat and becomes ready to accept a command. • When any other command is issued, the antenna discontinues Repeat and executes the new command. If the command format is wrong, the antenna returns the format error response 14 and discontinues Repeat. If a waiting time for tag (refer to Section 5-9-4) is set, when the waiting time for tag has been passed, the antenna returns the no-tag error response 72 and continues Repeat. (Host device) (Antenna) (Tag) Repeat command (Waits for tag approaching) (Waits for tag approaching) Not yet approached (1)The Repeat command is sent from the host device. (2)The antenna does not return a response until the tag approaches. Not yet approached (Waits for a response) Communication process Tag (1) Sleep Response Receives a response (3)When the tag passes the front of the antenna, the antenna communicates with the tag according to a command. (4)When the process has completed, the antenna returns a response of the communication end to the host device and waits for the next tag approaching. Pass (Waits for tag approaching) Pass (Waits for a response) Communication process Tag (2) Sleep Response Receives a response (Waits for tag approaching) Pass (Waits for a response) Waits for tag approaching 5-4 Not yet approached (5)When the tag passes the front of the antenna again, the antenna communicates with the tag. (6)When the process has completed, the antenna returns a response of the communication end to the host device. 5-2 Communication Operation Sequence 5-2-2 Communication Mode with Communication Designation (1) Polling When one host device controls several antennas, if a normal auto command is used, a response is returned when the tag communication has completed. In this case, several antennas return a response. For polling, the antenna returns the response at the request of the host device. So, some responses are not returned simultaneously and several antennas can be controlled. To terminate polling: • When an auto repeat cancel command (C2) is issued, the antenna discontinues Polling Auto/Polling Repeat and becomes ready to accept a command. • When any other command is issued, the antenna discontinues a polling mode and executes the new command. If the command format is wrong, the antenna returns the format error response 14 and discontinues Polling Auto/Polling Repeat. • If a waiting time for tag (refer to Section 5-9-4) is set, when the waiting time for tag has been passed, the antenna returns the no-tag error response 72 and discontinues Polling Auto. For Polling Auto, the antenna returns an error response and continues Polling Repeat. When a command is executed, the tag is in a sleep mode or standby mode according to the communication designation (C!, R!). 5-5 5-2 Communication Operation Sequence (Host device) (Antenna) (Tag) (Antenna) (Tag) Polling Auto command Station No. 00 Polling response Not yet approached Receives a response Polling Auto command Station No. 01 (Waits for tag approaching) Polling response Not yet approached Receives a response Requests a response Station No. 00 (Waits for tag approaching) Response of "Not yet approached" Not yet approached Receives a response Requests a response Station No. 01 (Waits for tag approaching) Response of "Not yet approached" Not yet approached Receives a response Communication process Tag Pass (Waits for tag approaching) Receives a response Requests a response Station No. 01 Receives a response 5-6 Response of "Not yet approached" (Waits for tag approaching) (6)When the tag passes the front of the antenna station No. 00, the antenna station No. 00 communicates with the tag. (7)When the response request is sent to the antenna which ended the communication with the tag, the antenna returns a response of process result and becomes ready to accept a command. Requests a response Station No. 00 Response (1)The Polling Auto command is sent from the host device to the antenna station No. 00. (2)Immediately after receiving the command, the antenna returns a response that the command has been accepted. (3)The Polling Auto command is sent from the host device to the antenna station No. 01. (4)Immediately after receiving the command, the antenna returns a response that the command has been accepted. (5)The host device can inquire the progress of process using a response request. If the tag has not yet approached, a response of "Not yet approached" is returned to the response request. Not yet approached 5-2 Communication Operation Sequence (2) Multi The communication to all the tags in the antenna communication area can be made. Multi Trigger and Multi Repeat commands are available: In Multi Trigger, the antenna communicates with all the tags in the communication area when it receives a command. When the process has completed, the antenna returns the communication end response (termination code 72). In Multi Repeat, the antenna waits for a tag when it receives a command. The antenna continues to communicate with all the tags coming in the communication area. To terminate Multi Repeat: • When an auto repeat cancel command (C2) is issued, the antenna discontinues Multi Repeat and becomes ready to accept a command. • When any other command is issued, the antenna discontinues Multi Repeat and executes the new command. If the command format is wrong, the antenna returns the format error response 14 and discontinues Multi Repeat. If a waiting time for tag (refer to Section 5-9-4) is set, when the waiting time for tag has been passed, the antenna returns the no-tag error response 72 and continues Multi Repeat. When a command is executed, the tag is in a sleep mode according to the communication designation (S!). An example of Multi Trigger is shown below. (Host device) (Antenna) (Tag) Multi Trigger command Communication process Tag (0) Response Receives a response Communication process Tag (1) Response Receives a response "Communication End" response "72" Receives a response Multi S/M/L Time Slot method (refer to "Appendix 1 - Glossary") is used to detect several tags. Select S, M or L to optimize the Multi communication time. Code Number of communicated tags Number of time slots Approximately 4 tags Approximately 8 tags Approximately 16 tags 16 32 5-7 5-2 Communication Operation Sequence 5-2-3 Other Communication Mode (1) Selective Access Every tag has an inherent ID code which cannot be rewritten. By using this ID code, communication can be performed to a particular tag of those in an antenna communication area. Executes ID Code Read (I!) Refer to Section 5-7-2. Reads an ID code of a tag in the communication area. Executes Tag Designation Read command Refer to Sections, 5-7-3, 5-7-5 and 5-7-7. Uses an ID code and executes a command to a designated tag. (2) Radio Wave Transmission ON mode Usually, an antenna transmits a radio wave after receiving a command from a host device. When the Radio Wave Transmission ON mode of antenna is enabled, regardless of any command from a host device, the antenna transmits a radio wave always. In the Radio Wave Transmission ON mode, an application that the ID tag moves fast may be available. Executes Radio Wave Transmission ON (A1) Refer to Section 5-9-1. Executes Read/Write Mode Initial value How to change mode The antenna does not transmits a radio wave when it waits for a command. When the antenna accepts a communication command, the antenna transmits a radio wave and communicate with a tag. When the communication has ended, the antenna stops transmitting a radio wave. Radio Wave Transmission OFF mode Radio Wave Transmission ON mode 5-8 Radio wave transmission status Radio Wave Transmission ON (A1) Refer to Section 5-9-1. How to switch to the Radio Wave Transmission OFF mode • Radio Wave Transmission OFF command (A0) Refer to Section 5-9-1. • Reset command (C0) Refer to Section 5-9-2. • Reset the power supply. Regardless of any command from a host device, the antenna transmits a radio wave always. 5-3 Communication Response Format (1) Command A text section of command consists of a command and option section which specifies information. The antenna receives a range from STX receiving to ETX correctly and, only when the antenna station No. and DA match, executes a command. After receiving STX, when the antenna receives STX again by the time the antenna receives ETX, the second STX shall be the beginning of the command. You can specify whether BCC is enabled or disabled. By default, BCC is disabled. How to specify whether BCC is enabled or disabled, refer to Section 5-9-7. • Disabling BCC *A value below shows the number of characters.

Command Response Communication time (1) One tag The communication designation is SU. N is the number of bytes. In case of Trigger, Auto and Repeat command. Command Communication time (ms) Read Write (without verification read) t = 11 + 0.03 * N Write (with verification read) t = 13 + 0.06 * N ID code read t = 10 Communication test t = 1,100 Communication time (msec) Write (with verification read) Read Write (without verification read) kbyte Correct Usage Communication speed (a maximum of 115.2 kbps) between a host device and antenna is faster than that between an antenna and tag. So, if the tags move to the front of the antenna one after another, use the polling command. 7-4 7-4 Communication Time (Reference) (2) Multi (several tags) The communication time of Multi command varies depending on the number of processed bytes, the number of tags and designation of communication designation S/M/L. Average values are shown below. Communication designation Number of tags Average communication time (ms) 17 Approximately 4 65 Approximately 8 128 Approximately 16 256 (3) How to calculate maximum movement speed of tag The maximum movement speed of tag moving at the front of antenna is calculated as follows: Travel Tag Travel in communication area Maximum movement speed = Communication time Antenna Example of calculation (1) Calculate the movable speed of tag, based on the distance 1 m between the antenna and tag and 32-byte read. If the distance is 2 m in the communication range 2m mode, the area width is 0.8 m. The communication time of 32-byte read is 12 ms. Maximum movement speed = 0.8 m 0.8 m = 4 km per minute (= 240 km per hour) 12 ms 0.012 x 1 / 60 (minutes) Example of calculation (2) Calculate the movable speed of tag, based on the distance 4 m between the antenna and tag and 256-byte read. If the distance is 4 m in the communication range 5 m mode, the area width is 1.5 m. The communication time of 256-byte read is 19 ms. Maximum movement speed = 1.5 m 1.5 m = 4.7 km per minute (= 280 km per hour) 19 ms 0.019 x 1 / 60 (minutes) Correct Usage The tag movement time above is a value of the best example. In an actual operation, taking into consideration peripheral objects and radio wave environment at the working site, design a system that a margin was removed from the calculated value and execute a test in the working site. 7-5 7-5 Mutual Interference Between Antennas (Reference) • If several antennas are used, the communication may fail due to mutual interference.

If the antenna and/or tag are inclined, the communication range becomes small. Install the tag paying attention to the tag angle. • For the tag rotating angle 0 degrees and 90 degrees, deterioration characteristic of communication range depending on the tag angle is shown below. • Because of antenna position in the tag, communication range deterioration varies depending on the installation angle (whether "+" or "-"). • Horizontal installation angle of tag Upward Tag rotating angle 90 degrees Tag rotating angle 0 degrees Antenna Antenna Tag Tag * A hatched area on the tag shows a logo.

Microwave This product uses 2450 MHz which is recognized as IMS band (for industrial, medical and scientific purpose) in the world. N•m Unit of torque based on SI (International System of Units). N is Newton. The old unit is "kgf•m". 1 kgf•m = 9.807 N•m. Appendix-1 Appendix 1 Glossary Response In this manual, this refers to a response returned by the Read/Write antenna after a host device issued an instruction to the Read/Write antenna. RFID Radio Frequency Identification, i.e., automatic identification with radio system. Data about object is stored in the ID tag memory and the data is read/written by a reader/writer without contacting. RS-232C Common physical interface standard of EIA (Electronics Industries Association). Communication speed 9600 bps can be achieved in communication range 15 m. RS-422A Common physical interface standard of EIA (Electronics Industries Association). RS-422A is more excellent in noise resistance than RS-232C and a maximum of 3000 m of communication range is available. Communication is performed through four wires. Two wires are for sending and the others are for receiving. RS-485 Common physical interface standard of EIA (Electronics Industries Association). The same line is used for both of sending and receiving. So, communications can be made through two wires. Second-generation low-power data communication system Remarkably applicable wireless LAN which was legislated in 1999. A wide range of frequency band 2400 to 2483.5 MHz can be used by the SS (Spread Spectrum) system and multiple channels are available. ARIB RCR STD-33 (1999) is the Standard. Sleep, sleep state The state that any communication to the Read/Write antenna is not performed. In this state, battery power is used only to back up data in SRAM and the power consumption is 1/100 or less of the state that the ID tag operates or communicates. Therefore, to extend the life of the battery of ID tag, we recommend you to put the ID tag in the sleep state whenever the ID tag does not work. When the ID tag receives a radio wave from the Read/Write antenna, the ID tag quits the sleep state and works. Specified low-power radio station A radio station that the antenna power is 10 mW or less. A user is not required to apply a license for radio station. This product is verified by Technical Regulation Conformity Certification of an official organization before shipment. SRAM Static RAM (Random Access Memory). Volatile memory. Data is backed up by battery. Standby, standby state The state that all the circuits in a tag are ready to operate after a command is executed. The battery power consumption is the same as that at an operation such as communication. As a period of the standby state becomes short, the life of the battery can be extended. Start-stop synchronization Asynchronous data communication system which does not use synchronizing clock. Communication line is only one. Use it when synchronizing clock cannot be sent. Tag In this manual, this refers to ID tag which is memory media accessed by the Read/Write antenna of the RFID system. As accurate technical term, this is referred to as "Transponder". We call it "Tag" because "Transponder" is hard to say. Terminating resistance Put at both ends of communication line to prevent reflection in the communication line in RS-422A/RS-485. Time slot One of the systems that the Read/Write antenna accesses several ID tags. This system adopts the time slot. For example, if "M" (the number of time slots = 16) is specified in the data exchange designation of a command, the antenna informs the ID tag that there are 16 time slots and every ID tag returns a response according to timing of any of 16 time slots. If responses of several ID tags collide with each other, the time slots for those tags are rearranged. For "M", if the number of tags are approximately 8, probability of rearrangement is reduced and the total data exchange time is not prolonged so much. Appendix-2 Appendix 1 Glossary Wake instruction A command for identification transmitted at every 100 msec when the Read/Write antenna transmitted a radio wave. The ID tag only can identify it. When the ID tag receives the wake instruction, the ID tag continues an operation. If the ID tag cannot receive the wake command, the ID tag enters the sleep state. The ID tag power-saving function described in Section 3-7 is achieved by utilizing this function.
