(7/30) 3. Operations of the Reader Writer 3.1 Outline of Operations The 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 to the High-end device. The status of the Reader Writer operations will be reflected on the Output / LED.
(8/30) 3.3 Memory Management on Tag There are two types of the tag in the memory capacity: 128 bytes (user area 112 bytes) and 256 bytes (user area 240 bytes). The memory area recognises every 8 bytes as one page, distinguished by such addresses as 00h ~ 07h, 08h ~0Fh, and so on.
(9/30) 3.4 Processing of Tag Memory (1) Process Contents The following three processes are executed on the Tag Memory 1) Data Read Reading data from Tag Memory in units of pages. The area to execute the Read command is selected at random up to 16 pages (CR control) / 28 pages (Number of characters control). 2) Data Write Writing data onto Tag Memory. The area to execute the Write command may be selected at random up to 16 pages (CR control) / 28 pages (Number of characters control).
(10/30) (2) Transmission Operations The following 6 transmission operations are executed by changing the process procedure and execution timing. Transmission operations are specified by commands during command transmission. 1) Single Trigger Transmission with Tag is executed immediately after receiving command and a response is transmitted. After response is transmitted, the Reader Writer will be on stand by for new commands.
(11/30) 3) FIFO Trigger The Reader Writer will communicate with Tag immediately after receiving command and transmit response. After transmission is completed, the Reader Writer will prohibit Tag from operating. The Reader Writer will be on stand by for commands after response is transmitted. During transmission with Tag, there MUST BE AN OPERATIONAL TAG (A TAG THAT IS NOT PROHIBITED FROM OPERATION) within the transmission area.
(12/30) 5) FIFO Continue After waiting for the Tag to approach, then communicates with the Tag and transmits a response. After transmission is completed, Tag will become inoperative. After transmitting a response, the Reader Writer will await Tag to approach again if it receives [ACK], and CONTINUE UNTIL THE READER WRITER RECEIVES A STOP COMMAND. When communicating with the Tag, THERE MUST BE ONLY ONE ACTIVE TAG within the transmission area.
(13/30) 4. Controlling the Reader Writer from High-end Devices 4.1 Communication Frame Frame format consists of 16 different types of data, “0” ~ “F,” in units of evennumber characters and a terminator [CR] (ASCII Code: 0Dh). Data section: within 272 characters (in even numbers) Data 1 Data Text Data 2 ...
(14/30) Write Multiple Write Byte Write Write Protection ACK NACK STOP Oscillation ON Oscillation Off Test 02 03 04 08 11 12 13 14 15 10 Writes data onto Tag Memory in unit of pages Writes the same data onto Tag Memory in unit of pages Writes data onto Tag Memory in unit of bytes Specifies setting or releasing write protection per page Is sent when High-end device successfully receives data Is sent when High-end device does not receive data successfully Stops processing of command being executed Activate
(15/30) (3) Completion Code The Reader Writer will return the response to the high-end unit by transmitting a completion code. The definitions of the completion codes are as follows: Class Completion Code Name Details Normal end 00 Normal end Normal operations completed. Communication Error between high-end unit and Reader Writer 10 Parity error ∗ 11 Framing error There is a framing error in the command received. 12 Overrun error There is an overrun error in the command received.
(16/30) 4.3 Commands Types and Responses (1) Read Read command is used when data is to be read from the Tag. Data for any specified page may be read. The maximum number of pages that may be read at one time is 16. n Command The pages to be read as parameters will be transmitted. Page specifications shall be made by specifying the bit indicating the page as “1” and the other bytes as “0”. This binary is converted to a hexadecimal and transmitted as a command. Pages can be specified at random.
(17/30) (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. The maximum number of pages onto which data may be written at one time is 16. n Command The pages to be written on, as parameters and the data to be written onto each page will be transmitted. Page specifications shall be made by specifying the bit indicating the page as “1” and the other bytes as “0”.
(18/30) (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 as parameters and the data to be written onto each page is transmitted. Page specifications shall be made by specifying the bit indicating the page as “1” and the other bytes as “0”.
(19/30) (4) Byte Write The Byte Write command is used when data is to be written onto the Tag in unit of Bytes. Data of any bytes can be written from the specified address. An area spanning over more than one page may be specified, but a maximum limit of 16 pages applies. n Command The area’s leading address and the data to be written as parameters will be transmitted. The address may be specified within the range of 00h ~ EFh.
(20/30) (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 as parameters will be transmitted. Page specifications shall be made by specifying the bit indicating the page as “1” and the other bytes as “0”. This binary is converted to a hexadecimal and transmitted as a command. If set and turn off were specified for the same page, the set command will have priority.
(21/30) (6) ACK ACK is transmitted after receiving the response during FIFO Continue operation, and it allows reading of the following: n Command Command “1” “1” Terminator CR n Response There is no response. (7) NACK When the High-end device was not able to receive a response correctly, NACK is transmitted to demand the response to be transmitted again. When the Reader Writer receives this command, the most recent response will be transmitted again.
(22/30) (9) Oscillation ON / OFF The Oscillation ON / OFF command specifies the oscillation of the antenna. n Command Oscillation ON Command “1” Oscillation OFF Terminator “4” Command CR “1” Terminator “5” CR n Response Completion Code “0” Terminator “0” CR (10) Test The Test command is to conduct transmission tests on the communication to the High-end device. When the Reader Writer receives this command, it transmits the same command to the High-end device.
(23/30) 5. Transmission Specification (Reference Values) 5.1 Transmission Distance The transmission distance specifications are as follows. Please take note that transmission distance is subject to change, depending on installation requirements. Please refer to “6. The Influence of Requirements of Use on Transmission Distance.” Tag Model V700-D13P31 Transmission Distance Still In motion Model V700-D13P21 Still In motion 8 ∼ 43 mm 20 ∼ 43 mm 8 ∼ 43 mm 20 ∼ 43 mm Note 1.
(24/30) 5.2 Transmission Area • Reader Writer: Model V700-HMD11 • Tag: Model V700-D13P31 / Model V700-D13P21 The transmission area diagram going through the center of the antenna and indicated on a flat surface vertical to the antenna surface is as indicated below. Read / write are the same area.
(25/30) 5.3 Communication Time The Model V700 Series has two communication times: the transmission time and the TAT (Turn Around Time). (1) Transmission Time This is the transmission processing time between the Reader Writer and the Tags. This time varies in accordance with the number of pages to be read / written. The transmission time values are as indicated below.
(26/30) 6. The Influence of Requirements of Use on Transmission Distance (Reference Values) When using the Reader Writer, transmission distance varies in accordance with the requirements of use (the existence / non-existence of metal objects in the vicinity, the use /non-use of multiple Reader Writer, power voltage value, etc.). This section indicates how such requirements and changes in them affect communication distance. Please use the following figures for your reference.
