About this Guide
This installation and usage guide explains how to install the V750 Reader, how to use the browser-based
interface, and how to control the reader remotely.
1.1 Before You Begin
1.1.1 Installation Requirements
•
The reader is shipped with a power source with a cable length of 4.2m (13ft9in).
•
Use only authorized antennas and cables to maintain FCC approval .
•
In order to comply with FCC requirements for RF exposure safety, a separation distance of at least 23 cm
(9.1 in) needs to be maintained between the radiating elements of the antenna and the bodies of nearby
persons.
•
Provide strain relief for all reader connections.
•
The minimum screw size for mounting the reader is M4. Use suitable wall anchors when mounting to
drywall or masonry whose thickness is 16mm or more.(Refer to 1.3.1 Install the Reader)
•
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.
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.
V750 RFID READER/WRITER, ANTENNA
OPERATION MANUAL
2006-06, REV.C
15 of 110
©OMRON CORPORATION 2006
•
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.

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 32.0 dBm.

2. Functions and Control
Reference Guide
This chapter lays the groundwork for the communication protocol between client software running on a remote
computer and the V750 reader.
2.1 System Interface
2.1.1 Command I/F function
Via 10/100BaseT Ethernet or RS-232C, the host issues a command to control the R/W. As the control method,
V750 employs original procedures. Same commands are used for Ethernet and or RS-232C.

Operating Mode
Operating Mode contains two modes, Operation Mode and Safe Mode.
Operation Mode: The R/W works as R/W normally.
Safe Mode: The R/W is being under recovering or being maintained after error.
The R/W will start up under Safe Mode if you push the Mode Switch for 1 second or more and release the
switch while the system is running, or if the R/W detects an error (ex. Hardware error or a failure of firmware
update) and it can not start up normally due to this error. Under Safe Mode, you can check the Status via Web
browser, initialize the setting, and write firmware.

2.1.2 Ethernet Protocol
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.
2.1.2.1 TCP Connection Setup and Teardown
A session between client software and the reader consists of connection setup, data transactions, and
connection teardown.
At present, all connections are initiated only by the client software. If, for example, the reader is configured to
automatically forward events and/or data to the client software but the client software has not established a
connection, then no attempt 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.
The client software sets up a TCP socket connection on reader port 7090. After connecting successfully,
communication between the client software and the reader can proceed as described below. Once the client
software has determined that communication has concluded, the connection must be terminated at the TCP
level. In order to prevent synchronization issues, each reader will support only one TCP connection.
Other transport protocols may be used to communicate between the client software and its subjugate readers.
The application-level protocol discussed below is neutral with respect to the transport layer.
2.1.2.2 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 browserbased interface.
The reader is with a static IP address which is default setting '192.168.1.200'. At first you can connect to the
reader using the default IP address and change IP address to adjust it to your network environment.
Default network setting:
IP Address:
Subnet Mask:
Gateway:
192.168.1.200
255.255.255.0
192.168.1.254
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.
How to change network settings is as the following:
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:
V750 RFID READER/WRITER, ANTENNA

IP address 192.168.1.100
Subnet mask 255.255.255.0
4. Browse to…
http://192.168.1.200 or
http://v740 (dhcp name)
The V750 reader browser-based interface to the reader is displayed.
5. Click the Set Reader 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.

under the Multi access mode. This is suitable for the place where the
reader reads a single tag at a time and the place which requires speed
and prompt control such as production process line.
Single Once
“SOC” This is used for communicating with single tag in the read field. Just
after the communication transaction, the result is returned promptly.
Single Repeat
“SRP”
2.Multi access
Multi Once
“MOC”
Multi Repeat
“MRP”
V750 RFID READER/WRITER, ANTENNA
OPERATION MANUAL
This is used for communicating with the single tag existing in the read

This method is used for communicating with one or more tag(s) in the
read field. It is suitable for the place where the reader reads various
numbers of tags existing in the read field such as logistics distribution
area.
This is used for communicating with multiple tags existing in the read
field. Just after the communication transaction, the result is returned
promptly.

< Operation timing of communication sequence>
(1)Single Once
The reader communicates with a single tag at a time (1:1 communication). When an antenna detects first tag, the reader
returns response and terminates transaction (1 response/ 1 transaction). If the reader does not detect any tag, it repeats the
transaction until timeout. In this case, the response indicates “0” as the tag number. If the timeout is specified as “0”, the
transaction will repeat until the termination command has been sent.

The reader communicates with a single tag at a time (1:1) and repeats the communication transaction. When the reader
detects first tag, it returns response to the host and still repeats its transaction. Whenever it detects unread tag, it returns
read results to the host. It repeats the sequence until the termination command has been sent.

The reader reads multiple tags repeating the reading transaction until timeout. Upon timeout, it returns results of
communication with tags to the host and it starts another time period to repeat the transaction until termination command
has been sent. At each timeout, the reader returns all read tag’s results to the host. If it does not read any tag during each
time period, it returns response meaning the number of tag = 0.

2.3.3 Session Setting
Following table shows 4 flags as a session flag for communication command. S0 is set as factory default
setting for Once command, and S2 is set for Repeat command.
Communication option
Flag
Description
Factory default setting.
Once
S0
In this setting, the reader communicates with all tags existing
・Single Once
in the read field whenever a command is executed.
・Multi Once
S1/S2/S3 In this setting, the reader communicates with un-read tags (it
ignores once-read tags.)
If S1 is set, tag refreshes its S1 flag when a specified time has
passed after flag setting (after communication transaction)
regardless of whether tag energized or not. It means that the
tags are read repeatedly in a certain interval.
If S2 or S3 is set, tag refreshes its S2 or S3 flag when a
specified time has passed after tag energizing stopped. It
means that the tag is not re-read unless the tag stays out of
the read field for the specified time.
Factory default setting.
Repeat
S2
In this setting, the reader communicates with new-detected
・Single Repeat
tags existing in the read field during the command execution.
・Multi Repeat
S0
When there is a tag the reader can not read because of flag
conflict with other readers, this setting enables the reader to
read the tag.
S1/S3
If another reader set in the near process line uses S2 flag, the
reader same flag may encounter the flag conflict. S1 and S3
flags are used to avoid this conflict.
Setting S3 provides same operation as S2 setting.
If S1 is set, tag refreshes its S1 flag when a specified time has
passed after flag setting (after communication transaction)
regardless of whether tag energized or not. It means that the
tags are read repeatedly in a certain interval.

2.3.4 Communication Data Control
(1) Filtering function
Filtering function enables the reader to communicate with selected tags that are suitable for pre-specified
conditions.
【Application examples】
- To read pallet tags selectively when item tags and pallet tags are existing together (EPC data).
- To read only the selected vender’s tag if there are various kind of venders’ tags (EPC data).
- To read the tags that has exclusive data format (the number of PC+EPC bit, NSI).
- To selectively read the specified tags that have certain supplier’s IC (Mask-designer identifier of TID).
(2) Smoothing function
Smoothing function consists of following three types. Using this function, the reader can reduce the quantity
of data transferred between the host and the reader.
1) Prevention of response duplication.
Under this function setting, the reader can prevent duplicated responses of same tag ID in a single
response frame.
2) Prevention of reread.
Under this function setting, the tag that has been already read does not reply in the transaction period
during the communication sequence (Single Repeat, Multi Repeat) which repeats its transaction,
3) Omission of No tag Response
This function enables the reader to omit the responses if it does not read any tag in the communication
sequence (Single Repeat, Multi Repeat) which repeats its transaction.

Note:
A parameter that an Interrogator uses to regulate the probability of Tag response. An Interrogator commands
Tags in an inventory round to load a Q-bit random (or pseudo-random) number into their slot counter; the
Interrogator may also command Tags to decrement their slot counter. Tags reply when the value in their slot
counter (i.e. their slot . see below) is zero. Q is an integer in the range (0,15); the corresponding Tag response
probabilities range from 20 = 1 to 2.15 = 0.000031.
Session
An inventory process comprising an Interrogator and an associated Tag population. An Interrogator chooses
one of four sessions and inventories Tags within that session. The Interrogator and associated Tag population
operate in one and only one session for the duration of an inventory round (defined above). For each session,
Tags maintain a corresponding inventoried flag. Sessions allow Tags to keep track of their inventoried status
separately for each of four possible time-interleaved inventory processes, using an independent inventoried
flag for each process.

Examples given in this chapter are provided as a guide for the user in determining suitability and does not
constitute a warranty. Users must verify operation in their specific environment and application.
3.2.1 Example １
To read tags attached to cases passed through a gate on a conveyer, the client software finds tags using 2
antennas. For the example pictured below, the command is as follows:
SELECT id, antenna_id FROM tag_id WHERE (antenna_id=1 OR antenna_id=2) AND
protocol_id='GEN2' AND read_count>1 SET time_out=500;
Then the reader continues to read tags through the gate.

time_out=300;
SET auto_time cursor_one = '2005-02-01T13:00:00Z', repeat=1000;
The first reader will start reading for no less than 300 ms at just 13 o’clock, and it will repeat the command
1000ms.
On Reader 2:
DECLARE cursor_two CURSOR FOR SELECT id FROM tag_id WHERE protocol_id='GEN2' AND
read_count>1 SET time_out=300;
SET auto_time cursor_two = '2005-02-01T13:00:00.5Z', repeat = 1000;
The second reader will start reading for no less than 300ms starting at time 0.5 second after 13 o’clock, and it
will repeat the command every 1000ms.
The effect will be that each reader will have a almost 50% duty cycle with each one only active when the other
one is off.

4.3 Safe Mode
Use the recessed Safe Mode button on the reader connector panel to recover from errors which prevent the
reader from operating in normal mode. In Safe Mode the reader is configured with a static IP address of
192.168.1.200. Safe mode operation restores factory default settings as follows:
IP Address:
Host Name:
192.168.1.200
Mercury4
Although the browser-based interface pages are displayed in red when operating in safe mode, the reader is
still functional, although it cannot read or write tags. In most cases, the reader will need to be reconfigured for
operation with the reader application after starting in Safe Mode.
1. With the reader running, hold down the recessed Mode Switch button for 1 seconds, using a nonconductive object.

Mode switch
2. Release the button
3. The green LED should turn solid as soon as the button is released, indicating the reader is rebooting. It
should take approximately 30 seconds to boot into Safe Mode. The web server, telnet server and SSH
server run in Safe Mode, however none of the RFID features are activated. To communicate with the
reader in Safe Mode, a PC must have an IP address and subnet mask that are compatible with the reader
settings, for example:
IP address 192.168.1.200
netmask
255.255.255.0
There are two main reasons to enter Safe Mode. One is to perform a firmware update to repair a corrupted
file system. The second is to change settings that are preventing the reader from operating normally.
Both of these tasks can be performed via the web interface.
4. Once the maintenance has been performed, restart the reader to activate the changes. Disconnect power
from the reader.

*. There are no RF reflection objects around the Antenna and Tag in the measurement environment.
*. There are some areas where communication is possible outside the communications range shown in the graph by the effect of
reflection off of the ground.
For example, radio anechoic chamber.
*. Class1b:3dB attenuator is attached at the time of measurement with a Antenna.
*. GEN2:DRM off mode

5.2 Communications Time
The following charts show communication time on each protocol. It is influenced on practical matters, for
example radio noise, distance between tags, materials tags are on and other environmental matters.
These charts are generated by plotting and linking average of actual communication time on every 5 tags.
Communication time is measured in shielded room with one reader, so that no reflection and no interference
are considered.
You can refer these charts on determining time out value of RQL command. But you must keep in mind actual
communication time on your environment may not correspond to these charts because of the reasons already
described.
