Main Features 英語内容確認
(1) Various communication performances and functions for various customers’ applications.
1) Selective communication modes to meet various applications.
Multi-access: optimizes a sequence automatically according to the number of tags existing in the read field.
Single-access: reads a tag in high speed if there is a single tag in the read field.
2) Wide-choice communication condition setting.
Multiple communication conditions can be combined for suitable usage..
3) Self-operation function that can build system at low cost.
Using two function; command register function and programmable function, the Reader/Writer can implement
simple judgment or processing without instruction from the host.
Command setting function
Can set the commands so that the command starts when power is on or input terminal signal is ON.
Programmable output terminals
4 outputs can be used for output terminals to show reader status or communication test results judgment.
When the output terminal is used for communication test resultsjudgment, the judgment conditions can be
changed by choosing criteria objective such as data value or tag numbers.
(2) Various Maintenance Functions and On-site Verification Functions.
1) Monitoring and Setting via Web browser.
Via Web browser, you can set functions to display an operation state or setting conditions or to set the
operation parameters easily by using PC.
2) Communication monitoring function that reduces the time to verify the system.
A tag communication test (Query), an on-site environmental monitoring function (a noise check, Channel, radio
wave monitor), and error logging function are equipped. This function shows the status of radio waves and
enables you to verify performance of tag-reader or analyze phenomenon that may change depending on on-
site RF environment.
3) Multiple LED operation displays
The multiple LED lamps show the reader operation state clearly and simply so that you can understand the
reader’s status and handle an error quickly if the error occurs.
4) Automatic antenna detection.
This function enables you to check the connection status of antennas and the R/W when a command is
executed. It helps to detect an error or problem of antenna(s) or wiring.
(3) Extendibility applicable to broad usage
1) Firmware upgradeable.
Via an Ethernet port, you can upgrade its software. It means that countermeasures can be taken easily against
an error and future functions are expandable. In addition to this, Safe Mode is also equipped so that the
reader/writer can recover from the upgrade error.

FCC WARNING
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s
authority to operate the equipment.
NOTICE
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to
part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment.
This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the user will be required to
correct the interference at his own expense.
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.

1. Installation and Usage Guide
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 2006-06, REV.C
OPERATION MANUAL 16 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.

V750 RFID READER/WRITER, ANTENNA 2006-06, REV.C
OPERATION MANUAL 17 of 110 ©OMRON CORPORATION 2006
1.2 Authorized Antennas
The antenna authorized by the FCC for use with the V750 Reader is described below.
IMPORTANT: No other antennas may be used with the V750 Reader without violating FCC regulations. It is
the responsibility of the user to comply with this requirement.
1.2.1 Antennas

1.2.2 Antenna Cables
The only cables authorized by the FCC for use with the V750 Reader are listed below:
Short cable (Options) Long cable
(Options)
Model: V740-A01-3.0M Model: V740-A01-10M
Length: 3.0m (9.8') Length: 10m (32.8')
Insertion Loss: 1.5 dB min. Insertion Loss: 1.5 dB min.
Cable Type: 3D-2V Cable Type: 5D-SFA
Connector: Reverse TNC to Type N Connector: Reverse TNC to Type N
Cable Diameter:5.5mm (0.22’’) Cable Diameter:7.6mm (0.30’’)
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.
Recommended Power Settings
Antenna Type Short Cable/Long Cable
V740-HS01CA
