1.1.2 Performance Considerations 1.1 Before You Begin Reader performance may be affected by external factors including tag variables and environment. 1.1.1 Installation Requirements • The reader is shipped with a certified limited power source with a cable length of 1.8m (6ft). Performance tests conducted under typical operating conditions at your site are recommended to help you optimize system performance. • Use only authorized antennas and cables to maintain FCC approval (see page 4).
PAGE 5
1.2.3 Setting the Reader RF Power 1.2 Authorized Antennas The antenna authorized by the FCC for use with the V740 Reader is described below. IMPORTANT: No other antennas may be used with the V740 Reader without violating FCC regulations. It is the responsibility of the user to comply with this requirement. 1.2.1 Antennas OMRON Mono-static Antenna(Options) During initial installation, the reader must be properly configured to use the correct RF power to comply with FCC regulations.

1.4 Reader Configuration In some cases, the application software may provide support for reader configuration. If so, follow the instructions provided with the application. The following procedure describes how to configure the reader directly from a network PC using the browser-based interface. The reader is shipped to use DHCP by default but will fall back to the following static network configuration if it does not get a DHCP lease: IP Address: Subnet Mask: Gateway: 10.0.0.101 255.255.255.0 10.0.0.1 6.

1.5 Reader Service Navigation menu 1.5.1 Using the Browser-Based Interface The browser-based interface communicates directly with the V740 reader. It includes several tools that enable you to monitor reader performance, change reader settings, and upgrade reader firmware. A navigation menu provides access to the following pages: • Status—Displays current operational settings. • Query—Allows the user to set timing of operation, set antennas, set RF air interface protocols, and read tags.
PAGE 11
Status Page Query Page The Status page shows the current settings of the reader. Use the Query page to monitor reader performance (read rags). The Query page is useful for verifying performance when installation is complete and for troubleshooting performance issues. The Query field includes a drop-down list (at the bottom-right of the screen) that enables you to specify the operating mode.
PAGE 12

1.6 Tag Fundamentals Class 1B Tags Class 1B tags contain 128 bits of programmable memory. The format is almost the same as the Class 1 tags. Bit count of EPC code is 96. Tag Memory Structure Protocols and the tag memory structures supported by the V740 reader are described below. For additional information regarding tag operation, refer to each tag specification. Class 0 Tags Class 0 tags contain 112 bits of read only memory. It consists of EPC Code and Check Code data.

2. Query Protocol 2.1 Transport Protocol Reference Guide In the current implementation, TCP/IP is used as the transport protocol. TCP is a connection-oriented protocol that provides a reliable, in-order data transport layer with end-to-end checksums and flow control. This chapter lays the groundwork for the communication protocol between client software running on a remote computer and the V740 Reader. The client software may be a database system, enterprise software, or user software.
PAGE 23
2.2 Event/Query Protocol The client software can control the reader using RQL via TCP connection and can acquire data from the readers in two modes: 1) by requesting specific data or 2) by automatically receiving events. The two modes are discussed in further detail in the following subsections. In order to keep the protocol comprehensive and easy to use, we specify a small set of commands that allow the client software to fully configure the readers and exploit their capabilities.
PAGE 24
2.2.2 General Observations, Commands, and Syntax We note that a reader behaves very much like database wherein each individual tag represents an entry in the database with a given set of attributes. Due to memory constraints of the reader, the system will remove entries from the database as they are queried. 2.2.3 Extended RQL Command Structure supported by the V740 Reader Extended Command Set for Data and Write, and Lock operations ID Read : Identify tags, including anti-collision.
PAGE 25
[id1] [id2] .....[idn] 2.2.4 Detailed Command Structure 2.2.4.1 ID Read The client software would use the SELECT command to read IDs of tags. The SELECT command is for querying the tag population of the reader as well as static variables such as firmware version. The structure of a SELECT command is as follows: The response includes the check code and ID. The first 4 digits are the check code, and the ID follows for the EPC1/1B protocols.
PAGE 26
• • To query a specific sub class of tags, given a range of tag ID values: When the client software reads tags of the 'EPC0' protocol, it should indicate 'read_count>1' in the 'where_specification'. SELECT id FROM tag_id WHERE protocol_id='EPC1' AND tag_id>=min_tag_id AND tag_id<=max_tag_id; For example, the command is as follows: The reader returns the tag ID values for all the present tags between min_tag_id and max_tag_id, which are hexadecimal values.
PAGE 27
(See 3.2 Communications Time) The constraints on the scheduler in the reader for the time_out are shown below. Time is equally divided among the specified protocols. The reader searches sequentially for each antenna in the time provided for the protocol. When the last antenna completes searching, the reader returns to the first antenna again. Following chart shows an example of time schedule given by the model command as below.

PAGE 29
2.2.4.2 ID Write The UPDATE command is used to write new data to a tag. This can be used to write a new tag_id. The structure of an UPDATE command is as follows: If wrong data is written to the tag, the tag may be unreadable. In this case, write correct tag ID again, after that, the tag would turn to be readable. UPDATE table_expression set_specification where_specification; table_expression and entries specified in set_specification are provided in Table 3.

2.2.4.3 Reader Control The client software can register a command with a cursor name to the reader. This section describes Cursors(Stored Procedures or Aliases ) and Reader settings. daemon to its initial state; that is, resets the reader, deletes cursors used clears memory. ii. Execution Commands stored as cursors can be executed in 3 ways as described below. i.
PAGE 32
milliseconds are spent with cursor idle(RF off). This syntax can be used for controlling the duty cycle of the reader. For full reader utilization, ensure that the value of time_out is less than the value of repeat, if not the cursor is executed continuously. The second form runs during the specified interval. The start and stop time are specified in ISO8601 time strings, of the form Auto Mode can be terminated by sending the command: YYYY-MM-DDTHH:mm:SS.
PAGE 33
If the current time has passed the start time and the stop time specified in the future, the cursor is executed immediately and finished at the specified stop time.

Table4 : Table Schema - Reader Control Keyword DECLARE Entry - Table n/a Arguments cursorname, Range Example Value Comments - cursor1 Defines the cursor name for the query. query FETCH - n/a cursorname - cursor1 Executes a cursor and sends the data CLOSE - n/a cursorname - cursor1 Deletes a defined cursor RESET - n/a - - - Resets the reader, deletes cursors, clears memory SET tirgger_time n/a cursorname, - - Set a cursor to run at the specified time once.
PAGE 35
2.2.4.4 Get Information The client software can get the information about the status of the reader. For example, firmware version and current time of the system. To get firmware version information,The format is as follows: SELECT entry FROM table_expression Table5 : Table Schema - Get Information Keyword SELECT FROM Entry Table Arguments Range Example Value Comments version Firmware String - 2.0.
PAGE 36
2.2.5 Errors If the reader is unable to execute a command issued by the client software, the reader issues an error message, which has the basic form: Error error_code : string where error_code is an integer. Error codes and strings are documented in Table 6. For example: DECLARE cursor9 CURSOR FOR SELECT id FROM tag_id; FETCH cursor10; Would result in the error message: Error 0100: Cursor does not exist V740 RFID READER/WRITER, ANTENNA OPERATION MANUAL 2005-07, REV.

2.2.6 Protocol Specific Functionality and Parameter Settings While the standard ID_read and anti-collision searches are supported by practically all offered protocols, therefore no protocol-specific information is required to issue RQL search. More specific commands, such as data_read and data_write require protocol specific information when formatting the query and interpreting the results. The tables below provide that information. 2.2.6.
