Revision history Revised date Revised item β β²98/ 7/ 17 New issue β²00/ 7/ 07 βApplicable Standardsβ is added on the page 2 (2/23) Applicable Standards FCC (USA) Part 15 subpart B and C This device complies with part 15 of the FCC Rules. Operation is subjected to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. FCC ID : E4E6CYAID7000100 FCC NOTICE This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment dose cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -Reorient or relocate the receiving antenna. -Increase the separation between the equipment and receiver. -Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -Consult the dealer or an experienced radio / TV technician for help. FCC WARNING Changes or modifications not expressly approved by the party responsible for compliance could void the userβs authority to operate the equipment. Properly shielded an grounded cables and connectors must be used for connection to host computer and / or peripherals in order to meet FCC emission limits. AC adapter with ferrite core must be used for RF interference suppression. Precautions of Use This device uses a frequency of 125 kHz to communicate with a tag. Some transceivers, motors, monitor units, and power supply (power IC) emit noise that adversely affects this communication with the tag. If this product is to be used in an environment close to such devices, please check the effects from these devices prior to use.

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. R/W Module Page 1 User Board Page 2 User CPU Tag Page n n Operations Timing Chart Initial process Status Waiting for command Receiving command Processing command Transmitting response Waiting command Command TXD Response RXD Tag communications COMM β Output / NORM LED β ERR β RUN β 3.2 Oscillation Control The R/W Module supplies power to the Tag by oscillating the antenna, and thus conducts communication with the Tag. The Module may be set on either the βOscillate Modeβ βStop Modeβ depending on whether the Module should oscillate while not in communication with the Tag. The βStop Modeβ conserves dissipation power, and enables the R/W Module antenna to be installed close to the Tag to conduct communications on a time sharing basis. The βOscillate Modeβ allows the Module to constantly supply power to the Tag for FIFO processing. Oscillation Status Operation Mode Switching Conditions Stop Mode (conserves dissipation power) The antenna stops oscillating while not processing commands β’ Mode switching conditions at start-up β’ When oscillation OFF command is active Oscillation Mode (enables high-speed processing) The antenna is constantly oscillating β’ When oscillation ON command is active β’ When option is active in FIFO Trigger / FIFO Auto Command (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. However, if writing of the command in process requires more than one page, not all pages may be completely rewritten. 3.4 Memory Management on Tag The Tags used to conduct communication with the R/W Module may be one of the following two types depending on memory capacity: 128 bytes (user area 112 bytes) or 256 bytes (user area 240 bytes). The memory area recognizes every 8 bytes as one page, distinguished by such addresses as 00h ~ 07h, 08h ~ 0Fh, and so on. n Memory Map (00h ~ EFh indicates to address) Page 8 bytes / page 00h 01h 02h 03h 04h 05h 06h 07h 08h 09h 0Ah 0Bh 0Ch 0Dh 0Eh 0Fh 10h 11h 12h β β β β β β 17h 18h 19h 1Ah β β β β β β 1Fh 20h 27h 28h 2Fh 30h 37h 10 11 112 bytes 12 13 14 68h β β β β β β 6Fh 15 70h β β β β β β 77h 16 78h β β β β β β 7Fh 29 E0h E1h β β β β β β E7h 30 E8h E9h β β β β β β EFh 240 bytes (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. Certain data within a page may be selected in units of bytes to be written onto the Tag Memory (byte write). 3) Write Protection Set/OFF Write protection may be set on the selected pages of Tag Memory. When write protection is set, the data may be read, but not re-written. Write protection may be set on any of the pages. Write protection may be set or turned off by commands. (2) Communication Operations The following 6 communications operation may be executed by changing the process procedure and execution timing. Communication operations may be specified by commands during command transmission. 1) Single Trigger Communication with Tag will be executed immediately after receiving command and a response will be transmitted. After response is transmitted, the Module will be on stand by for new commands. During communication with the Tag, there may only be one Tag within the communication area. β¦ Operation Sequence Processing will be executed once only after receiving command. If there is no Tag, a Tag absent error message will be transmitted. User β Command User β Command Response 1 (Tag Absence Error) Tag Communication Command Process Tag Operation Response 2 Tag 1 Command Process (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. β¦ Operation Sequence After receiving command, the Module waits for the Tag to approach, then executes process once only after Tag is detected. When Module receives a STOP command, the command will be completed. User β Command STOP Command User β Response Tag Communication Response Command Process Tag Detection Tag 1 Tag Operation 3) Tag Detection (Truncation Process) FIFO Trigger Module will communicate with Tag immediately after receiving command and transmit response. After communication is completed, Module will prohibit Tag from operating. Module will be on stand by for commands after response is transmitted. During communication with 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 βOscillation Modeβ β¦ Operation Sequence Upon receiving command, Module will execute process once only. If there is no Tag, a Tag absence error will be transmitted. During processing of the command, Tag will become inoperative, and thus will not respond to the next command. Oscillation will continue after command is processed.

After transmitting a response, Module will await Tag to approach again if it receives [ACK], and CONTINUE UNTIL MODULE RECEIVES A STOP COMMAND. When communicating with the Tag, THERE MUST ONLY BE ONE ACTIVE TAG within the communication area. β¦ Operation Sequence Upon receiving the command, Module awaits Tag to approach. When Tag is detected, Module executes command and transmits a response. Afterwards, when [ACK] is received, Module 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 Module receives a STOP command, processing will stop.
