(4ports) V740-HS01CA Mono-static Antenna (Circular)
V740-HS01LA Mono-static
Antenna (Linear)
The OMRON V750 RFID Reader (herein after denoted as the reader) uses RFID (radio frequency
identification) technology to read data stored on RFID tags.
The reader supports UHF (ultra high frequency) antennas, which are available separately. The reader receives
tag data through the UHF antenna and transfers data to a remote computer over a network connection.
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 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.

Main Features
(1) Well-tuned communication performance and functions for customers’ applications
1) Selective communication modes for various applications
Single access mode: reads a tag in high speed if there is a single tag in the communication field.
Multi access mode: optimizes a sequence automatically according to the number of tags existing in
the communication field.
2) Various communication condition setting
Multiple communication conditions suit user’s optional usage.
3) Self-operation function
Using two function; command entry function and programmable output function, the reader can
implement simple judgment or processing without instruction from the host.
- Command entry
Can set a command so that the command starts when power is turned on or input terminal
signal is on.
- Programmable output
4 outputs can be used for output terminals to show reader status or communication results.
When the output terminal is used for communication results, the result conditions can be set by
choosing criteria objective such as data value or tag count.
(2) Rich maintenance functions and on-site verification functions
1) Monitoring and setting via Web browser.
Via Web browser, you can get an operation status or setting conditions and set the operation
parameters easily.
2) Communication monitoring function that reduces the installation time
A tag communication testing function, an on-site environmental monitoring function (a noise check for
each channel), and an error logging function are equipped. These functions show the status of radio
waves and enable you to verify performance of tag-reader or analyze phenomena that may change
depending on on-site RF environment.
3) Multiple LED operation displays
The multiple LED indicators show the reader operation status clearly and simply so that you can
understand the status and handle an error quickly if it happens to occur.
4) Automatic antenna detection
This function enables you to check the connection status of antennas when a command is executed.
It helps to detect an error or problem of antenna(s) or wiring.
(3) Expandability applicable to broad usage
Firmware upgradable
Via Web browser on the PC, you can upgrade its firmware. It means that the functions are
expandable.

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 DC cable whose length is 2.9m (9.6ft).
•Use only authorized antennas and cables to conform to the local laws and regulations.
•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 1.4.1 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 detectability 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 to
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 2.5).
Environment
Reader performance may be affected by the following:
•Metal surfaces such as desks, filing cabinets, bookshelves, and waste cans 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.

15 of 135 ©
•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.

19 of 135
1.3.3 Setting the reader RF Power
During initial installation, the reader must be properly configured to use the correct RF power. 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:
Maximum RF power = 35dBm (3.28W e.i.r.p 2W e.r.p) - 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 (35 – 6.0 + 1.5) = 30.5 dBm.
The reader RF Power is set through the Communication Settings Page as described on Page107.
Recommended Power Settings
Antenna Type Short Cable/ Long Cable/ Super Long Cable
V740-HS01CA
V740-HS01LA 30.5 dBm
NOTE: Make sure the power setting is within the local low and regulation concerning radio.
