The OMRON V740 RFID Reader (herein after
denoted as the V740 Reader) uses RFID (radio
frequency identification) technology to read data
stored on RFID tags. The V740 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.
The V740 Reader is powered by ThingMagic LLC
Mercury4®technologies.

OPERATION MANUAL 8 of 56 ©OMRON CORPORATION 2005
1.1 Before You Begin
1.1.1 Installation Requirements
•The reader is shipped with a power source with
a cable length of 1.8m (6ft).
•Use only authorized antennas and cables to
maintain FCC approval .
•Properly shielded a grounded cables and
connectors must be used for connection to
host computer and / or peripherals in order to
meet FCC emission limits.
（AC adaptor）with ferrite core must be used
for RF interference suppression.
•Provide strain relief for all reader connections.
•The minimum screw size for mounting the
reader is #12 (M5). Use suitable wall anchors
when mounting to drywall or masonry.
•A Shielded Ethernet cable must be used to
communicate with other devices.
•Multiple readers and antennas can be used in
combination to enhance detection at specific
locations provided the software application is
able to synchronize antenna operation.
•Recommended minimum configuration for a
computer running an application that interfaces
with the V740 Reader:
– Pentium® 400 MHz processor
– 128MB memory
– 10 GB hard disk drive
– Base-T-10/100 Ethernet® port
1.1.2 Performance Considerations
Reader performance may be affected by external
factors including tag variables and environment.
Performance tests conducted under typical
operating conditions at your site are recommended
to help you optimize system performance.
Tag Variables
There are several variables associated with tags
that can affect reader performance:
•Application surface — Some materials interfere
with tag performance including metal and
moisture. Tags applied to items made from or
containing these materials may not perform as
expected.
•Tag orientation — Reader performance is
affected by the orientation of the tag in the
antenna field.
•Tag model — many tag models are available.
Each model has its own performance
characteristics(refer to Chapter 3).
Environment
Reader performance may be affected by the
following:
•Metal surfaces such as desks, filing cabinets,
bookshelves, and wastebaskets may enhance
or degrade reader performance.
Mount antennas as far as possible from metal
surfaces that are adversely affecting system
performance.
•Devices that operate at 900 MHz, such as
cordless phones and wireless LANs, can
interfere with reader performance.
These devices may degrade performance of
the reader. The reader may also adversely
affect performance of 900 MHz devices.
•Antennas operating in close proximity may
interfere with one another, thus degrading
reader performance.
•Interference from other antennas may be
eliminated or reduced by using either one or
both of the following strategies:
– Affected antennas may be synchronized by a
separate user application using a time-
multiplexing strategy.
– Antenna power can be reduced by reconfiguring
the RF Transmit Power setting for the reader.

V740 RFID READER/WRITER, ANTENNA 2005-09, REV0.1
OPERATION MANUAL 9 of 56 ©OMRON CORPORATION 2005
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.

1.2.3 Setting the Reader RF Power
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
the recommended power setting as calculated below.
The maximum RF power is determined from antenna
gain and antenna cable loss using the formula:
Pmax = 36 dBm - Antenna Gain + Cable Loss
For example, if the antenna has a maximum gain of 6
dBi, and the cable has a minimum loss of 1.5 dB, the
maximum RF power that may be set is (36- 6 + 1.5) =
31.5 dBm.
The Reader RF Power is set through the Settings
Page as described on Page18.
Note that in no case may the power be set higher than
31.5 dBm.

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: 10.0.0.101
Subnet Mask: 255.255.255.0
Gateway: 10.0.0.1
If you are not using DHCP, you must know the IP
address and subnet mask settings for the network
environment in which the reader will be running. If you
are using DHCP, you must have a means of finding
the reader, typically by having a DHCP server update
a DNS server. Another way of finding readers on a
network is to use the Zeroconf protocol, which Apple
calls Bonjour™. (formerly called Rendezvous. Apple
provides a downloadable Bonjour plug-in for Windows
Internet Explorer at their web site:
http://www.apple.com/macosx/features/bonjour/).
Note: Please contact Apple about operating the
Bonjour ™ technology.
1. Exit any reader applications that are running on
the network.
IMPORTANT: Running another reader application
while using the browser-based interface may
cause a reader error. If this happens, reboot the
reader or restart the system using the browser-
based interface.
2. Verify that the reader is operational. All LED’s
should be out except for the green power LED
which should be pulsing.
3. Start a Java-enabled web browser from any
network-enabled PC. This PC must be configured
with an IP address and subnet mask compatible
with the reader’s settings. For example:
IP address 10.0.0.10
Subnet mask 255.255.255.0
4. Browse to…
http://v740 (dhcp name) or
http://10.0.0.101
The V740 reader browser-based interface to the
reader is displayed.
5. Click the Settings link in the navigation menu.
The Modify Settings page appears.
6. If you wish to use DHCP, modify the “Use
DHCP?” setting by selecting the “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. Then, click the [Save Changes] button.
IMPORTANT: Do not disconnect power until the
save process is completed.
7. Set the reader RF power per instructions on page
to correspond to antenna and cable types.
8. Verify that the settings shown are correct. Then,
restart the reader by disconnecting the power
cable and then reconnecting it.
It may take about 60 seconds for the reader to
restart. If the reader IP address was changed, you
must type the new address into the PC browser
address field to communicate with the reader.
IMPORTANT: Do not disconnect and connect
power cable at the DC cord. Always disconnect
and connect power cable at the AC cord.
9. Once the system restarts, click Settings. You are
taken to the Modify Settings page. Your changes
will be saved and then applied. After the reader
reconfigures its network interfaces, it will
automatically redirect you to its status page.
There is no need to restart the reader.
IMPORTANT: Do not disconnect power while the
reader is saving its new configuration.
The reader is now ready to receive commands
from the network.
10. Use the Query page of the browser-based
interface to verify the reader and antenna
operation by reading tags.
11. Close the browser window. Start an application to
control the reader on the network.

Query Page
The Query page is mainly used to set up and run anti-
collision searches quickly and gives you immediate
feedback, which can be useful for verifying
performance when installation is complete and for
debugging.
At the bottom of the screen is the Query field in which
RQL search statements can be entered or selected
from the stock queries found in the drop-down list to
the right of the Query field. The RQL search statement
in the Query field specifies which tag protocols will be
read, which antenna ports are to be used, how long
the query is to be run, and other read operation
parameters. The query can be run once or
continuously.
Note: The selected settings DO NOT affect reader
performance associated with other applications.
The following stock queries are available from the
drop-down list:
Each mode provides the most suitable time out value
for the protocols and the number of tags to be read.
zfewer than 10 EPC1 tags
zfewer than 50 EPC1 tags
zfewer than 100 EPC1 tags
Note: Only the modes that contain EPC1are
available on this type of V740 reader.

Write Page
Use the Write page to replace the id or data that is
encoded on a tag.
Consider the following guidelines when writing to tags:
•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 tags can be written.
•The id or data to be written must match exactly
the number of hexadecimal characters (numerals
from 0-9 and letters from A-F) specified by the
tag’s protocol. For example: 64-bit EPC1 tag ids
are 16 hexadecimal characters long.
•To write one tag, place the tag in the antenna field.
If multiple tags are present, they will all be
encoded with the same EPC data.
•Use the antenna connected to port 1 of the reader
To write ids or data to a tag:
1. Click the Write link on the navigation menu. The
Write page appears.
2. In the middle pane, type or paste a hexadecimal
tag id to be written to the tag in the RQL
statement after tag_id=0x. ( For example: 16 hex
characters for 64-bit tags, 24 characters for 96-bit
tags, etc.)
3. Select the checkbox for EPC1.
4. Click the Make Update button. A query designed
to write the highlighted data to the tag appears in
the center pane.
5. Place the tag 0.3–0.6m (1–2ft) from the antenna
connected to the port 1.
Verify that no other tags are in the antenna’s field.
6. Click the Submit Query button to write the data. If
the write was successful, the new tag id appears
in the bottom pane.
If the write is not successful, the response will
include an error message.
To read data from a tag:
1. Display the Write page (click the Write link on the
navigation menu).
2. Click the Make Select button. A query designed
to read data from the antenna connected to the
port 1 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.

Settings Page
Use the Modify Settings page to change RFID
protocol, network and reader security settings. The
page is divided into five sections: RFID Protocol
Settings; Network Settings: All Interfaces; Network
Settings: Ethernet Interface; Boot Options and
Security Settings.Instructions for Modifying the
Settings.
1. Click the Settings link on the navigation menu.
The Modify Settings page appears.
2. Enter the required settings.
3. Click the Save Changes button to save the new
settings.
IMPORTANT: Do not disconnect power until the
save process is complete.
(see 1.5.2 Restarting the Reader on page 25).
Instructions for Modifying the Settings
Changing these parameters changes the reader’s
settings used on startup. RFID protocol settings, boot
options and 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.
IMPORTANT: Do not disconnect power until the save
process is complete.
Static network settings are ignored when in DHCP
mode, and DHCP related settings are ignored when in
static IP mode. Please note that your network needs
to have properly configured DNS servers if you wish
to connect to the reader via its hostname. Usually
when using DHCP, the DHCP server will add the
hostname to the DNS server’s database.
The reader adjusts time by NTP only once when it
starts up. You should confirm if the time is correct
using Get information command (Ref. Section
2.2.4.4).
Note that new RFID, network and security settings
take effect after saving. Boot-related options are
saved but DO NOT take effect until the reader is
restarted. Therefore, to ensure that all new settings
take effect, it is recommended that you restart the
reader whenever reconfiguring and after saving the
new settings.
Note: Please ask the network administrator about the
network settings in your environment.
