(9/23) 3. Operations of the R/W Module 3.1 Outline of operations The R/W Module receives commands from the User board, executes read / write processes on the Tag, and returns a response of the results of the process to the User board. The status of the R/W Module operations will be reflected on the Output / LED.
(10/23) 3.3 Input STOP When a STOP signal is input to the R/W Module, receiving and processing of commands and command processing will stop and then, after the STOP signal is deactivated, the Module will be on stand by for new commands. When the STOP signal is input, oscillation will stop regardless of the setting of the oscillation control mode. If a STOP signal is input more than 50 msec prior to shut down, writing of unstable data to the Tag may be prevented.
(11/23) 3.5 Processing Tag Memory (1) Process Contents The following three processes may be executed on the Tag Memory 1) Read Reading data from Tag Memory. The area to execute the Read command may be selected at random up to 16 pages. 2) Write Writing data onto Tag Memory. The area to execute the Write command may be selected at random up to 16 pages. When writing the same data onto all pages (multiple write), there is no limitation on the number of pages.
(12/23) 2) Single Auto After receiving command, the Module waits for the Tag to approach, communicates with the Tag, and then transmits a response. Once the response is transmitted, Module will be on stand by for new commands. During communication with the Tag, there must be one Tag within the communication area. ♦ Operation Sequence After receiving command, the Module waits for the Tag to approach, then executes process once only after Tag is detected.
(13/23) 4) FIFO Auto Module will await Tag to approach after receiving command, then communicate with Tag and transmit response. After communication is completed, Module will prohibit Tag from operating. Module will be on stand by after response transmission is completed. During communication with the Tag, there MUST BE AN OPERATIONAL TAG (A TAG THAT IS NOT PROHIBITED FROM OPERATION) within the communication area. When this command is executed, Module automatically activates “Oscillation Mode.
(14/23) 6) FIFO Repeat After receiving command, the Module waits for the Tag to approach, then communicates with the Tag and transmits a response. After communication is completed, Tag will become inoperative. MODULE WILL CONTINUE PROCESS UNTIL IT RECEIVES A STOP COMMAND. When communicating with the Tag, THERE MUST ONLY BE ONE ACTIVE TAG (A TAG THAT IS NOT PROHIBITED FROM OPERATION) within the communication area. ♦ Operation Sequence Upon receiving the command, Module awaits Tag to approach.
(15/23) 4.2 Command/Response Format n Command The frame consists of an operation option, parameters, and terminator. Communication options can be attached to commands No. 01 through 08 only. Command Option Parameter 1 ~ Parameter n Terminator Cr n Response The frame consists of a completion code, parameters, and terminator.
(16/23) (2) Options Specifies communication operations when command is one of 01 through 08.
(17/23) n Response The completion code (“00”when successful) and read data will be transmitted. The read data will be transmitted continuously according to the order of page specification. Completion code “0” “0” Read data* ⋅⋅⋅ (Data 1) Terminator (Data n) Cr *Data number n = specified page × 8 (2) Write The Write command is used when data is to be written onto the Tag Memory in units of pages. Data can be written on any specified page.
(18/23) (3) Multiple Write The Multiple Write command is used when the same data is written in units of pages. Pages may be specified at random. There is no limit on the number of pages that may be written at one time. n Command The designated pages to be written and the data to be written onto each page is transmitted as parameters. Page specifications shall be made by specifying the bit indicating the page as 1 and the other bits as 0.
(19/23) (5) Write Protection The Write Protection command is used to set or turn off write protection on Tag. n Command The pages to set or turn off write protection on will be transmitted as parameters. Page specifications shall be made by specifying the bit indicating the page as 1 and the other bits as 0. If set and turn off were specified for the same page, the set command will have priority.
(20/23) (7) NACK When the User board was not able to receive a response correctly, NACK is transmitted to demand that the response to be transmitted again. When the R/w Module receives this command, the most recent response will be transmitted again. n Command Command “1” Terminator “2” Cr n Response The most recent response will be transmitted again. (8) STOP The STOP command is used to stop the R/W Module from executing a command.
(21/23) (10) Test The Test command is to conduct transmission tests on the transmission to the User board. When the R/W Module receives this command, it transmits the same command to the User board.
(22/23) 5. Error Code List (1) Transmission Between User board and R/W Module Completion Code Name Details 10 Parity error • There is a parity error in one of the characters among the command received. 11 Framing error • There is a framing error in one of the characters among the command received. 12 Overrun error • There is an overrun error in one of the characters among the command received.
