Introduction
The AR400 Reader 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.

RFID Components
Symbol’s 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 AR400 RFID Reader
The Symbol AR400 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).
Figure 1-2. AR400 Reader, Top and Side Views
The AR400 provides a wide range of features that enable implementation of complete, high-
performance, and intelligent RFID solutions.
Multiple Connection Options
The AR400 provides flexibility for connecting to networks via Ethernet or serial connection. Because
each AR400 is identified by its unique IP address, it is accessible from anywhere on the network. The
AR400 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 AR400. 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 AR400 is easy to reconfigure for an application via the Setup Wizard. The AR400 can also accept
new firmware and configuration under host control.
Tag Management
Ad Hoc Querying
Use ad hoc querying to send a query about tag visibility. The AR400 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 AR400 offers two types of filtering:
• Pre-Processing: The AR400 restricts its ability to read tags as directed by the include or exclude filtering
specification.
• Post Processing: The AR400 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 AR400 supports sending exception notifications via Simple Network Management Protocol
(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 Administrator Console.
SNMP Integration
The AR400 can send real-time notification of specific events and failures to the SNMP server.
Security
Trusted Hosts
The AR400 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 AR400 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.
Use this feature to assign different access levels to users, allowing them to perform necessary tasks
without compromising security.
Logging
The AR400 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.
LEDs
The AR400 LEDs indicate reader status as described in LED Indications .

Use only the parts provided with the AR400 reader or recommended by Symbol.
Substituting other cables or parts can degrade system performance, damage the AR400,
and/or void the warranty.
Installing the AR400
Mounting Tips
Consider the following before selecting a location for the AR400 reader:
• Mount the AR400 indoors, in operating range, and out of direct sunlight, high moisture, or extreme
temperatures.
• Mount the AR400 in an area free from electromagnetic interference. Sources of interference include
generators, pumps, converters, non-interruptible power supplies, AC switching relays, light dimmers, and
computer CRT terminals.
• Mount the AR400 within 15 feet of the antennas.
• Ensure the AR400’s power cord can reach the power source outlet.
• Mount the AR400 onto a permanent fixture, such as a wall or a shelf, where it won't be disturbed,
bumped, or damaged. Allow a minimum of five inches of clearance on all sides of the AR400.

When installing the antenna, ensure a minimum separation distance of 9.1 in (23
cm) between the antenna and human beings.

Mounting the AR400
1. Position the AR400 on the wall or shelf, ensuring 5 inches (12.7 cm) of clearance on all sides.
2. Using the pre-drilled holes at the corners of the AR400 as a guide, drill four holes in the wall or shelf
for mounting the AR400.
3. Secure the AR400 to the wall or shelf using four 1-inch long #10 screws.
Connecting Antennas to the AR400
Power off the AR400 before connecting the antennas. Never disconnect the
antennas while the AR400 is powered on or reading tags (when the yellow LED is lit).
Doing so can damage the AR400.
Do not turn on the antenna ports from a host to which antennas are not connected.
1. Attach the N-Male plug (large end) of an antenna connector cable to antenna 1.
2. Attach the DIN 1.0/2.3 jack connectors (small ends) of the cable to the TX1and RX1connectors on
the AR400.
3. Secure the cable using wire ties. Do not bend the cable.
Repeat these steps to connect antenna 2 to Tx2/Rx2, antenna 3 to TX3/RX3, and antenna 4to TX4/RX4.
Portal Setup
In portal situations such as dock doors, ensure the TX for an antenna on one side of the portal faces
the TX of the opposing antenna. Similarly, ensure the antennas’ respective RXs face each other, as
shown in Portal Alignment .Antenna Pair 1 Antenna Pair 2
Figure 2-2. Portal Alignment
Powering the AR400
Connect the antennas before supplying power to the AR400.

To power on (and off) the AR400:
1. Connect the provided 24 VDC power supply to the AR400’s power port.
2. Plug the power supply into a 24 V power outlet. The green Power LED on the AR400 lights to
indicate the AR400 is powered on.
3. To power off the AR400, unplug the power supply from the power outlet. The green Power LED
turns off to indicate that the device is powered off and the system is not operational.
Do not power off the AR400 until the yellow LED is off, indicating that reads are not in
process.
Verifying Hardware Functionality
Power On Test
The red Error LED lights when power is supplied to the AR400, then turns off. The green Power LED
lights when the AR400 completes power-up and is operational.
Read Test
After the AR400 powers up, test the read range to verify that it meets requirements.
1. Enable polling using the Web-based AR400 Administrator Console.See Scan Control on page 3-6.
2. Control the AR400 through a real-time application such as TagVis. Refer to the TagVis User Guide.
3. Present a tag so it is facing the antenna.
4. Walk slowly toward the antenna until the AR400 lights the yellow Read LED to indicate that it
detected and read the tag. The distance between the tag and the antenna is the approximate read
range.
For optimal read results, do not hold the tag at an angle or wave the tag, as this can
cause the read distance to vary.
Connecting the AR400 for Communication
Connect the AR400 to a host or network via Ethernet or RS232.

Ethernet Connection
The AR400 communicates to the host via a 10/100Base-T Ethernet cable and receives power via a
Symbol AC power supply. Ethernet connection allows access to the AR400’s Administrator Console,
used to change AR400 settings.
To connect the AR400 via Ethernet:
1. Connect the RJ45 Ethernet cable to the 10/100Base-T Ethernet port on the AR400. See AR400
Parts . Ensure the Ethernet cable is terminated according to Table A-2 on page A-5.
2. Plug the other end of the Ethernet cable into the host system’s LAN port.
If not connecting to an Ethernet network, connect one end of an Ethernet crossover cable (not
provided) to the Ethernet card on the computer, and the other end to the TCP/IP port on the AR400.
3. On a networked computer, open an Internet browser and enter the IP address of the AR400 (the
default IP address of the AR400 is 192.168.127.254). The Administrator Console login window
appears.
4. Log in to the AR400 Administrator Console. If desired, change settings for the AR400, such as the
IP address. See Chapter 3, Administrator Console.
RS232 Connection
Serial communication allows accessing the AR400’s Administrator Console using terminal software in
order to change AR400 settings. Use this method of administration rather than the Web-based method
in the following situations:
• When the IP address of the AR400 is unknown.
• When the AR400 obtains its IP address via DHCP but you need to know the IP address.
• When crossover cables are not available and you need to change the IP address of the AR400 as per the
network's addressing scheme.
• Other situations when AR400 administration is necessary without connecting to the Web-based Administrator
Console.
• The Web-based Administrator Console is disabled.
To connect the AR400 via RS232:
1. Connect a DB9 serial cable to the AR400’s RS232 port. See AR400 Parts. Ensure the cable is
terminated according to Table A-3 on page A-5.
2. Plug the other end of the cable into the host computer.
3. On the host computer, launch a terminal emulation program (such as HyperTerminal) and configure
it as follows:
• Terminal Type: VT-100
• Port: COM 1-4 (depending on the COM port used)
• Terminal Settings:
• 38400 bps transfer rate
• 8 data bits
• no parity
• 1 stop bit
• no flow control
