Section 2. System Description

Matrics develops and markets Radio Frequency Identification (RFID) solutions that are effective and affordable by offering a combination of low cost, long read range, and a very high read rate unmatched by other RFID systems. A Matrics RFID System gives you real-time, end-to-end visibility of products and assets in your factory, distribution center, retail outlet, or other facility. A typical Matrics RFID system consists of these main components:

•Silicon-based RFID tags that can be attached to vehicles, trailers, containers, pallets, boxes, etc., to create a “people-free” wireless environment for tracking assets; and

•Reader network components (readers, antennas, cables, connectors, power supplies, etc.) that power and communicate with the tags.

Product Description

The Matrics AR 400 Reader is a true multi-protocol reader providing real-time, seamless tag processing for all EPC-compliant tags: Class 0 (Read), Class 0+ (Read/Write), and Class 1 (Read/Write). This operational flexibility is useful in protecting customers’ RFID infrastructure investment.

The AR 400 is architected to be an intelligent reader. It provides a rich feature set for tag management such as tag filtering, reconciliation, user defined association and selective visibility. The AR 400 also provides timely and pertinent information to customers’ Network Management platform by real-time reporting of events and status using SNMP. To address security concerns, it provides security and privilege controls and full traceability of operator actions.

The AR 400 is a ready-to-connect network element that provides a variety of options for connecting to customers’ corporate networks via Ethernet or Serial connections and wirelessly via 802.11. A configuration Setup Wizard makes commissioning tags extremely easy.

All these new capabilities further enhance Matrics’ industry-leading performance. With improved dynamic range, AR 400 remains Best-in-Class in RF performance with a typical read range in excess of 25 feet. Matrics’ patented contention-free protocol to communicate with tags provides unmatched read rates of up to 1,000 tags per second for Class 0/0+ tags. Using advanced digital signal processing techniques, the AR 400 allows superior interference management to operate in noisy environments.

Other key features include:

•Up to four (4) individually addressable antennas (read points), reducing cost per read point;

•Allows read point grouping;

•Local tag buffering;

•Tag filtering;

•Ad-hoc tag querying;

•Event notification and real-time reporting; and

Mount the Reader

Before mounting the Reader, you must select a location for it. For best results, consider the following when determining the optimal placement for your Reader:

Mount the Reader indoors, in operating range, and out of direct sunlight, high moisture, or extreme temperatures.

Mount the Reader in an area free from electromagnetic interference. Such sources of interference may include: generators, pumps, converters, non-interruptible power supplies, AC switching relays, light dimmers, computer CRT terminals, etc.

Mount the Reader within 15 feet of your antennas (antenna connector cables from

Matrics are 15-feet long.)

Make sure the local power supply cord, when attached to the Reader, can reach the power source outlet.

Do not mount the Reader within 12 inches of a computer CRT terminal.

Make sure that you will be mounting the Reader onto a permanent fixture (wall or shelf) where it won’t get disturbed, bumped, or damaged. Keep in mind that you will need five

(5) inches of clearance on all sides of the Reader.

WARNING: The antenna must be installed in a manner that ensures a minimum separation distance of 23 centimeters between the antenna and human beings.

CAUTION: If the Reader is not installed properly, it could be damaged and your system performance diminished.

To mount the Reader:

1.Position the AR 400 Reader at the desired mounting position on the wall or shelf. Make sure that there are five (5) inches of clearance on all sides of the Reader.

2.Using the pre-drilled holes at the corners of the Reader to guide you, drill four holes for mounting the reader.

3.Securely affix the Reader to the wall of shelf using the four screws that you provided.

10	AR 400 Reader User’s Manual 2003-2004 Matrics, Inc.

Connect Antenna(s) to the Reader

Attach your antenna(s) to the Reader in sequential order (first connecting Antenna 1 to Reader connectors Tx1 and Rx1, then Antenna 2 to Reader connectors Tx2 and Rx2, Antenna 3 to the Tx3/Rx3 connectors next, and Antenna 4 to the Tx4/Rx4 connectors last.)

1.Attach the large ends of your antenna connector cables to the large connectors on the antenna.

2.Attach the small ends of the cables to the corresponding connectors on the Reader (Antenna 1 to Reader connectors Tx1 and Rx1, etc.)

3.Secure your cables using wire ties (do not bend the cables.)

WARNING: Do not disconnect antenna cables when actively reading tags (if the LED is lit on the Reader, don’t disconnect the antenna cables.) You could severely damage your Reader. Make sure that you unplug the power supply to power off the system first before disconnecting cables.

Connect the Reader to a Host Computer

The steps you must follow to interface the Reader with your system depend upon the software package you choose to use. Contact Matrics (refer to the “Contact Us” section in this User’s Manual) for more information.

Power On (and Off) the Reader

1.Connect the provided 24vDC power supply to the Reader’s Unit Power port.

2.To power on the system, insert the plug end of the power supply into a 24v power outlet. The green Power/Link LED on the Reader should turn on, indicating that the Reader is powered on and the system is live.

3.To power off the Reader, unplug the power supply from the power outlet. The green Power/Link LED on the Reader should turn off, indicating that the Reader is powered off and the system is not operational.

AR 400 Reader User’s Manual 2003-2004 Matrics, Inc.

11

Verify the Reader Installation

Reader On?

After you have installed the AR 400 Reader as described in this User’s Manual, test that the Reader is on by following the instructions provided above in the “Power on (and Off) the Reader” section.

To verify that the Reader is operational, power it on by plugging the power supply (attached to the Reader) into the appropriate power outlet. The green Power/Link LED on the Reader should turn on, indicating that the Reader is powered on and the system is operational.

Test Read Range

After you have installed the AR 400 Reader as described in this User’s Manual, test the read distance of your hardware configuration to verify that it meets your needs.

1.To measure the read distance between the Reader and a tag, hold a tag in front of you (with the tag face parallel to the antenna face.)

2.Walk slowly toward the antenna until the Reader responds by lighting the yellow Read LED. This indicates that the Reader has detected and read the tag.

NOTE: For purposes of this test, we recommend that you do not hold the tag at an angle, or wave the tag in front of the antenna, as that may cause the measured read distance to vary.

3.In order to read the same tag again, first remove the tag completely from the Reader’s read field, and then perform Step 2 again.

12	AR 400 Reader User’s Manual 2003-2004 Matrics, Inc.

Create Read Point Classes

A read point is an individually addressable antenna. Every read point must have a read point class associated with it, which is where you define certain parameters in an effort to fine tune the performance and characteristics of the read point.

Multiple read points may share a single read point class. So, once you define a read point class, you can re-use it many times without re-entering the same parameters over and over again.

You can add a new read point class from scratch (naming it and specifically setting its parameters), or you can use an existing read point class as a template (copying its settings, and renaming it.)

1.If you haven’t already done so, launch and log in to the Reader Administrator Console.

2.Click the Read Point Class link on the left-hand side of any page. The Read Point Classes page displays.

3.To add a new read point class, enter the following information:

•A unique Class Name (one that does not already exist in the system),

•The antenna Type--AREA (long range), SHELFv1 (existing short range shelf type), SHELFv2 (next generation short range shelf type), COMBINED1, or COMBINED2,

•Set the Scan Period to tell how often the read point is to be checked for tags,

•Set the Gain (as a percentage) to designate the antenna’s power setting,

18	AR 400 Reader User’s Manual 2003-2004 Matrics, Inc.

•Set Retry to tell the Reader how many times to repeat the read command each time a scan is to be performed,

•Set Air Protocol to All, Class 0, or Class 1 to tell the Reader which protocol to use to interrogate tags, and
