Chapter 5 Control from Host Device 5-1 Operation Status of Read/Write Antenna and ID Tag The V690 Series REID system communicates with a tag according to the instruction of a command (1) sent from a host device and returns the result to the host device as the response (3). 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.
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.
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.
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.
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.
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.
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.
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.
