4 Ports – Reader/Writer

V740-HS02C Dual Patch Antenna

The OMRON V740 RFID Reader/Writer (herein

after denoted as Reader) uses RFID (radio

frequency identification) technology to read data

stored on RFID tags. The Reader operates

analogous to an SQL (structured query language)

server, providing tag data in response to requests

from another application. A separate software

application may be used to direct its operation and

provide a user interface.

The Reader supports UHF (ultra high frequency)

antennas, which are available separately. The

Reader supports multiple configurations of UHF

antenna ports and transfers data to a remote

computer over a network connection.

Performance Considerations About this Guide Reader performance may be affected by external factors including tag variables and environment. This installation and usage guide explains how to install the V740 Reader, how to use the browserbased interface, and how to control the Reader remotely. . Performance tests conducted under typical operating conditions at your site are recommended to help you optimize system performance.

Setting the Reader RF Power Authorized Antennas During initial installation, the Reader must be properly configured to use the correct RF power to comply with FCC regulations. DO NOT increase the power beyond this level. The only antennas authorized by the FCC for use with the V740 Reader/Writer are listed below. Detailed information on each antenna is available from their respective manufacturers.

Install the Antennas Reader Installation The antennas can be mounted directly to a variety of surfaces. Follow the installation instructions provided with the antennas. The following parts are provided with the Reader: Part Qty.

These setting apply to both the LAN interface and the wireless interface. If you wish to use DHCP select the DHCP? Yes radio button; otherwise, enter the required network settings in the IP Address, Subnet Mask, and Gateway fields. The fields will turn red if the gateway is not on the same subnet as the IP address.

Consider the following guidelines when writing to tags: • Show Raw button displays raw tag data on the Query page. Each entry shows Reader, protocol, antenna, and tag data. • Always place a tag 0.3–0.6m (1–2ft) from the antenna when writing data. The tag may be damaged if it is too close to the antenna. • Only unlocked 915 MHz tags can be used. The write function is not supported for 13.56 MHz tag protocols.

network settings can be modified. Care must be taken to use correct values or you might be unable to connect the Reader without restarting into safe mode. 2. Click the Make Select button. A query designed to read data from the antenna connected to UHF1 appears in the center pane. 3. Place the tag to be read within the detection zone of the antenna. 4. Click the Submit Query button to read tag data. Query results appear in the bottom pane.

Although the browser-based interface pages are displayed in red when operating in Safe mode, the Reader is fully functional. In most cases, the Reader will need to be reconfigured for operation with the Reader application after starting in Safe mode. Help Page Use the Help page to view descriptions of system operations. 1. Disconnect power from the Reader. 2. Depress and hold the Safe Mode button, using a nonconductive object, while restoring power to the Reader.

is made by the Reader to contact the client software to establish a connection. Furthermore, if an extant connection terminates unexpectedly, the Reader will not attempt to contact the client software to re-establish a connection. All responsibility for opening, maintaining, and closing the connection during a session rests with client software. V740 RFID Reader Query Protocol The client software sets up a TCP socket connection on Reader port 8080.
PAGE 15
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. The syntax for querying against this database is derived from SQL syntax. In the simplest case, the client software explicitly requests data by polling the Readers.

PAGE 17
RQL Table Schema As was mentioned before, RQL is derived from the SQL language, which allows the user to define arbitrary tables. RQL has predefined tables according to the schema below. NOTE: Tag_id and Tad_data values are case-sensitive and are all lowercase only.

event (‘\n’) if tags matching the WHERE clause are not present. The first version requests a read from a specific antenna, while the second does not. The second command imposes a time out constraint of 500ms; i.e., the Reader stops reading and returns all collected data after 500ms. The order in which specifying arguments are used is irrelevant. The default timeout if none is specified is 250ms. table and col entries are provided in Table 1.
PAGE 19
Every 500 milliseconds, the Reader spends 250 milliseconds querying for tags. The remaining 250 milliseconds are spent with 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 no less than the value of repeat. DECLARE cursorname CURSOR FOR query cursorname — an arbitrary string. query — a SQL query (SELECT/UPDATE statement), as defined above.
PAGE 20
The constraints on the scheduler in the V740 for the time_out are shown below. Time is equally divided among the specified protocols, and then divided among the antennas. V740 will search 3 protocols for 250 ms: EPC0, EPC1, and ISO18000-6b will each get a 83.3ms slot. This will allow all 20 EPC0 tags to be read, but not all EPC1 tags. For all protocols except EPC0, the antenna arbitration algorithm is optimized for the maximizing the read rate of the tags in the field.
PAGE 21
SET trigger_time c1 = '2004-0214T18:54:50Z'; Use of RQL for Scheduled Reads The V740 uses the Network Time Protocol as a means to establish absolute time on the Reader. With that capability in place the Reader is enabled to execute tag operations that have been scheduled relative to absolute time. Here is how it works.

Protocol Specific Functionality and Parameter Settings While the standard ID_read and anti-collision searches are supported by practically all offered protocols, hence no protocol-specific information is required to issue and 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.

The second Reader will start reading for no less then 350 ms (it will probably run over to roughly 500 ms) starting at time 500ms, and it will repeat the command every 1000 ms.
