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 three 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, • Reader network components (readers, antennas, cables, connectors, power supplies, etc.) that power and communicate with the tags, and • The Matrics Visibility Manager (MVM) software that runs on your choice of host computer and collects tag data automatically. Product Description The Matrics Long Range Reader (PN: RDR-090) is an industrial strength fixed Reader targeted to indoor applications, such as warehouses. The Reader offers superior and robust read range capabilities, anti-collision features, and very high data read rates unmatched by other systems. It can be easily mounted in areas of ingress and egress where large numbers of tagged objects are inbound or outbound in a logistics process. It is packaged ready to be interfaced to your host computer, and can easily be programmed to perform specific tasks. The Reader provides all of the RF and control functions required to power and communicate with Matrics passive RFID tags (PN: SDR-001 and DDS-001.) It sends digital data to the tag (through one antenna at any given time) on a pulse width modulated On Off Keyed (OOK) transmitter signal, demodulates the identification signal received from the tag, and then sends the data to your host computer. The Matrics Reader network is structured to allow for flexibility in system configurations and in the arrangement of read points to optimize coverage at a low overall cost. A typical configuration consists of up to four (4) high performance antennas attached directly to a single Reader. The system also employs a unique, patented reader-driven interrogation protocol that allows several hundred tags to be read each second. This powerful read rate supplies the muscle to overcome interference in noisy environments, and to guarantee the accuracy of reads when tags are moving at high velocities. It also assures acceptable data collection timing when reading large volumes of inventory. Readers can be powered either locally or through the network cable in the event there is not a local power source near by, and to minimize overall network infrastructure costs. 2 Long Range Reader User’s Manual  2002 Matrics, Inc.

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. CAUTION: If the Reader is not installed properly, it could be damaged and your system performance diminished. Long Range Reader User’s Manual  2002 Matrics, Inc. 7
To mount the Reader: 1. Position the Reader (PN: RDR-090) at the desired mounting position on the wall, shelf, or enclosure. 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. 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 for more information. Regardless of the software you use to do it, you must change your Readers’ factory-assigned xFF address to a unique address for communicating with your host computer. Power On (and Off) the Reader 1. Connect a 24V DC power supply (such as PN: PWR-001, available from Matrics) to the Reader’s Unit Power port. 2. To power on the system, insert the plug end of the power supply into a power outlet. The Power/Activity LED on the Reader should light red, indicating that the Reader is powered on and the system is live. 8 Long Range Reader User’s Manual  2002 Matrics, Inc.
3. To power off the Reader, unplug the power supply from the power outlet. The Power/Activity LED on the Reader should turn off, indicating that the Reader is powered off and the system is not operational. Verify the Reader Installation Reader On? After you have installed the 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 Power/Activity LED on the Reader should light red, indicating that the Reader is powered on and the system is operational. Test Read Range After you have installed the Reader as described in this User’s Manual, you should test the read distance of your hardware configuration to verify that it meets your needs. To do so, you’ll need a tag, and access to an application (such as the one provided in Matrics’ Evaluation System) that can communicate with your Reader to process tag data in a continuously polling mode of operation. 1. Remove all but one tag from the 50-foot test area. 2. Load and run your application that will communicate with (and process tag data from) the Reader. 3. Verify that the Reader’s LED is flashing, indicating that it is properly communicating with your application. 4. Hold a tag in front of you (with the tag face parallel to the Reader face) close to the Reader antenna. 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 Reader, as that may cause inconsistencies in your test results. 5. Using your application, verify that Reader has detected and read the tag. 6. Walk slowly with the tag, moving it around to the extreme edges of the test area. 7. Using your application, adjust the Reader’s power output to ensure desired areas read the tag and undesired areas do not. 8. Repeat this procedure for each antenna on all Readers in your system.
