(7/30)3. Operations of the Reader Writer3.1 Outline of OperationsThe Reader Writer receives commands from the High-end device, executes read /write processes on the Tag, and returns a response of the results of the process tothe High-end device. The status of the Reader Writer operations will be reflectedon the Output / LED.n Operations Timing ChartPower ONStatus Initialprocess Waitingcommand Receivingcommand Processingcommand Transmittingresponse WaitingcommandTXD CommandRXD ResponseTagcommunicationsGreenLEDRed3.2 Oscillation ControlThe Reader Writer supplies power to the Tag by oscillating the antenna, and thusconducts communication with the Tag. The Reader Writer may be set on either the“Oscillate Mode” “Stop Mode” depending on whether the Reader Writer shouldoscillate while not in communication with the Tag. The “Stop Mode” conservesdissipation power, and enables the Reader Writer antenna to be installed close tothe Tag to conduct communications on a time sharing basis. The “Oscillate Mode”allows the Reader Writer to constantly supply power to the Tag for FIFO processing.Oscillation Status Operation Mode Switching ConditionsStop Mode(conservesdissipation power)The antenna stopsoscillating while notprocessing commands• When power is start-up• When oscillation OFFcommand is executedOscillation Mode(enables high-speed processing)The antenna isconstantly oscillating • When oscillation ONcommand is executed• When option data of FIFOTrigger / FIFO AutoCommands is executed40~105ms
(8/30)3.3 Memory Management on TagThere are two types of the tag in the memory capacity: 128 bytes (user area 112bytes) and 256 bytes (user area 240 bytes). The memory area recognises every 8bytes as one page, distinguished by such addresses as 00h ~ 07h, 08h ~0Fh, andso on.n Memory Map (00h ~ EFh indicates memory address)Page 8 bytes / page1 00h 01h 02h 03h 04h 05h 06h 07h2 08h 09h 0Ah 0Bh 0Ch 0Dh 0Eh 0Fh3 10h 11h 12h ⋅⋅⋅ ⋅⋅⋅ 17h4 18h 19h 1Ah ⋅⋅⋅ ⋅⋅⋅ 1Fh5 20h 27h6 28h 2Fh7 30h 37h8910 : :11 : :121314 68h ⋅⋅⋅ ⋅⋅⋅ 6Fh15 70h ⋅⋅⋅ ⋅⋅⋅ 77h16 78h ⋅⋅⋅ ⋅⋅⋅ 7Fh: : :: : :29 E0h E1h ⋅⋅⋅ ⋅⋅⋅ E7h30 E8h E9h ⋅⋅⋅ ⋅⋅⋅ EFh112 bytes240 bytes
(9/30)3.4 Processing of Tag Memory(1) Process ContentsThe following three processes are executed on the Tag Memory1) Data ReadReading data from Tag Memory in units of pages. The area to execute theRead command is selected at random up to 16 pages (CR control) / 28 pages(Number of characters control).2) Data WriteWriting data onto Tag Memory. The area to execute the Write command maybe selected at random up to 16 pages (CR control) / 28 pages (Number ofcharacters control). When writing the same data onto all pages (multiple write),there is no limitation on the number of pages. Certain data may be selected inunits of bytes to be written onto the Tag Memory (byte write).3) Write Protection Set/ClearWrite protection is set on the selected pages of Tag Memory. When writeprotection is set, the data may be read, but not be written. Write protectionmay be set on any of the pages. Write protection may be set or turned off bycommands. Set / Clear is conducted by using the write protect command (08).
(10/30)(2) Transmission OperationsThe following 6 transmission operations are executed by changing the processprocedure and execution timing. Transmission operations are specified bycommands during command transmission.1) Single TriggerTransmission with Tag is executed immediately after receiving commandand a response is transmitted. After response is transmitted, the ReaderWriter will be on stand by for new commands. During transmission withthe Tag, there must be only one Tag within the transmission area.♦ Operation SequenceProcessing is executed once only after receiving command. If there is noTag, a Tag absent error message will be transmitted.2) Single AutoAfter receiving command, the Reader Writer waits for the Tag to approach,communicates with the Tag, and then transmits a response. Once theresponse is transmitted, the Reader Writer will be on stand by for newcommands. During transmission with the Tag, there must be one Tagwithin the transmission area.♦ Operation SequenceAfter receiving command, the Reader Writer waits for the Tag to approach,then executes process once only after Tag is detected. When the ReaderWriter receives a STOP command, the command will be completed.TagTransmissionTag 1Tag Operation←High-endHigh-end→Command CommandResponse 2(Tag AbsenceError)Command ProcessCommand ProcessResponse 1ResponseTagTransmissionTag 1Tag Operation←High-endHigh-end→CommandCommandSTOP(TerminationProcess)Tag DetectionTagDetectionCommand ProcessResponse
(11/30)3) FIFO TriggerThe Reader Writer will communicate with Tag immediately after receivingcommand and transmit response. After transmission is completed, theReader Writer will prohibit Tag from operating. The Reader Writer will beon stand by for commands after response is transmitted. Duringtransmission with Tag, there MUST BE AN OPERATIONAL TAG (A TAGTHAT IS NOT PROHIBITED FROM OPERATION) within the transmissionarea. When this command is executed, the Reader Writer automaticallyactivates “Oscillation Mode”♦ Operation SequenceUpon receiving command, the Reader Writer will execute process onceonly. If there is no Tag, a Tag absence error will be transmitted. Duringprocessing of the command, Tag will become inoperative, and thus Tagsthat have completed transmissions will not respond to the next command.Oscillation will continue after command is processed.4) FIFO AutoThe Reader Writer will await Tag to approach after receiving command,then communicate with Tag and transmit response. After transmission iscompleted, the Reader Writer will prohibit Tag from operating. The ReaderWriter will be on stand by after response transmission is completed.During transmission with the Tag, there MUST BE AN OPERATIONALTAG (A TAG THAT IS NOT PROHIBITED FROM OPERATION) within thetransmission area. When this command is executed, Moduleautomatically activates “Oscillation Mode.”♦ Operation SequenceAfter receiving command, the Reader Writer waits for the Tag to approach,then executes process once only after Tag is detected. During processingof the command, Tag will become inoperative, and thus Tags that havecompleted transmissions will not respond to the next command.Oscillation will continue after command is processed. When the ReaderWriter receives a STOP command, the command will be completed.However, oscillation after completion of command continues.(Oscillation)Tag 1Command CommandResponseSTOPResponse 11TagTransmissionTag Operation←High-endHigh-end→Tag DetectionTagDetectionCommand Process(TerminationProcess)Tag 1TagTransmissionTag Operation←High-endHigh-end→Command Command(Tag Absence Error)Command ProcessCommand Process(Oscillation)(Oscillation)ResponseResponse
(12/30)5) FIFO ContinueAfter waiting for the Tag to approach, then communicates with the Tagand transmits a response. After transmission is completed, Tag willbecome inoperative. After transmitting a response, the Reader Writer willawait Tag to approach again if it receives [ACK], and CONTINUE UNTILTHE READER WRITER RECEIVES A STOP COMMAND. Whencommunicating with the Tag, THERE MUST BE ONLY ONE ACTIVE TAGwithin the transmission area.♦ Operation SequenceUpon receiving the command, the Reader Writer awaits Tag to approach.When Tag is detected, the Reader Writer executes command andtransmits a response. Afterwards, when [ACK] is received, the ReaderWriter repeats the same operation. Once process is executed on a Tag,the Tag becomes inoperative, and thus a Tag will only be processed once.When the Reader Writer receives a STOP command, processing will stop.6) FIFO RepeatAfter waiting for the Tag to approach, then the Reader Writercommunicates with the Tag and transmits a response. After transmissionis completed, Tag will become inoperative. THE READER WRITER WILLCONTINUE PROCESS UNTIL IT RECEIVES A STOP COMMAND. Whencommunicating with the Tag, THERE MUST BE ONLY ONE ACTIVE TAG(A TAG THAT IS NOT PROHIBITED FROM OPERATION) within thetransmission area.♦ Operation SequenceUpon receiving the command, the Reader Writer awaits Tag to approach.When Tag is detected, the Reader Writer executes command andtransmits a response. Afterwards, the Reader Writer repeats the sameoperation. Once process is executed on a Tag, the Tag becomesinoperative, and thus a Tag will only be processed once.
