Introduction
The XR400 is a ready-to-connect network element that offers a variety of options for connecting to corporate networks via Ethernet
or serial connections. A Setup Wizard facilitates reader configuration.
RFID Technology
Radio Frequency Identification (RFID) is an advanced automatic identification (Auto ID) technology that uses radio frequency signals
to identify “tagged” items. A typical RFID system consists of transponders called tags, readers, and antennas, which function as
follows:
• An RFID tag contains a chip that can store a limited amount of data. This data may be pre-encoded or can be encoded in the
field. Tags come in a variety of shapes and sizes.
• A reader sends out radio frequency waves using attached antennas. This RF field powers and charges the tags, which are
tuned to receive radio waves. The tags use this power to transmit data back to the reader, which the reader converts to a
format for computer storage. The computer application translates the data into an understandable format.
Figure 1-1. RFID System Elements
RFID Components
Symbol’s Radio Frequency Identification (RFID) solutions offer low cost, long read range, and a very high read rate, providing real-
time, end-to-end visibility of products and assets in the factory, distribution center, retail outlet, or other facility. A typical Symbol
RFID system consists of the following components:
• Silicon-based RFID tags that can be attached to vehicles, trailers, containers, pallets, boxes, etc.
• Different types of antennas to support applications such as dock door (area antennas), conveyor and, in the future, Smart
Shelf (Shelf Antennas)
• Readers that power and communicate with the tags for data capture and provide host connectivity for data migration.
Tags
Tags contain embedded chips that store information unique to the objects to which they are applied. Available in various shapes and
sizes, tags, often called transponders, receive and respond to requests for their data. Tags require power to send data, and are
available with two power options:
• Active Tags: typically powered by light-weight batteries and have limited life.
• Passive Tags: powered by the reader’s RF field. Passive tags are much lighter, less expensive, and have a much longer life
than active tags.

Antennas
Antennas transmit and receive radio frequency signals under the control of a reader. Antennas do not perform processing. A read
point is the RF range of an antenna.
Readers
Readers are devices that provide a means for communicating with the tags and transferring their data to a host computer. Readers
also provide features such as filtering, parity checks, and tag writing.
The XR400 RFID Reader
The Symbol XR400 is an intelligent, multi-protocol reader that provides real-time, seamless tag processing for all EPC-compliant tags:
Class 0 (Read Only), Class 0 (Read/Write, also known as Class 0+), and Class 1 (Read/Write). Class 0 and Class 1 protocols are run in
the Ultra-High Frequency range (~900MHz).
The XR400 offers a variety of options for connecting to corporate networks via Ethernet or serial connection. A Setup Wizard
simplifies configuration.
Figure 1-2. XR400, Top and Side Views
The XR400 provides a wide range of features that enable implementation of complete, high-performance, and intelligent RFID
solutions.
Multiple Connection Options
The XR400 provides flexibility for connecting to networks via Ethernet or serial connection. Because each XR400 is identified by its
unique IP address, it is accessible from anywhere on the network. The XR400 can also be configured to obtain its IP Address from a
DHCP server, automating the IP address and default Gateway configurations.
Flexible Read Point Configurations
Connect up to eight antennas (four transmit and four receive) to a single XR400. This decreases the per-read-point cost. Logically
combine antennas to create a single, “wide” read point with a much greater range than that of a single antenna.
Configuration and Upgrading
The XR400 is easy to reconfigure for an application via the Setup Wizard. The XR400 can also accept new firmware and configuration
under host control.

Tag Management Features
Ad Hoc Querying
Use ad hoc querying to send a query about tag visibility. The XR400 replies with either “Tag(s) Visible,” “Not Known” (never seen or
imported), or “Not Visible” (previously seen but now missing, with last seen timestamp).
Tag Filtering
Use tag filtering to apply filters during read operations. A filter can include or exclude a tag based on the specified bit pattern. The
XR400 offers two types of filtering:
• Pre-Processing: The XR400 restricts its ability to read tags as directed by the include or exclude filtering specification.
• Post Processing: The XR400 reads all tags it sees, and applies its filters before it reports these tags to the host computer.
Tag List
Use the tag list feature to send information about tags from the host to the reader. The host can purge the tag list to remove this
information from the reader when it’s not needed.
Event Management
Event Notification
Use event notification to receive notification about certain events. For example, receive immediate notification of a tag visibility
change, or bundle all notifications and receive them later.
Exception Notification and Heart Beat Notification
The XR400 supports sending exception notifications via SNMP. The "heart beat" notification feature sends periodic messages that
indicate whether or not the reader is functional.
Device Management
Quick Backup and Recovery
To back up and restore reader configuration, use any Web browser to download the configuration XML file, then download the file to
the reader using the Reader Administrator console.
SNMP Integration
The XR400 can send real-time notification of specific events and failures to the SNMP server.
Security Features
Trusted Hosts
The XR400 allows specifying the IP addresses of hosts that are allowed to connect to the reader. Use this security feature to prevent
unauthorized network hosts from communicating with the reader.
User Level Security
The XR400 recognizes three access levels to assign to users:
•View - view reader configuration settings.
•Edit - view and edit configuration settings.
•Maintenance - view and edit configuration settings, and perform administrative tasks such as updating reader firmware.

XR400 RFID Reader Integrator Guide1-6
Use this feature to assign different access levels to users, allowing them to perform necessary tasks without compromising security.
Logging
The XR400 keeps a log of all system-related activities for security and troubleshooting. Use the log, which includes time-stamped
system activities such as good and bad tag reads, login attempts, hardware failures, and other events, to pinpoint problems to
facilitate quick resolution, and to identify administrators who require additional training to prevent future problems.
LED Indicators
The XR400 LEDs indicate reader status as described in Table 1-1.
