The host computer can be locally connected to the reader via RS-232, or at a remote network location. The RFID Reader is delivered with the following components and accessories: One ARL-9640 RFID Reader One RS-232 serial cable (for host computer) One power supply Documentation on CD-ROM HARDWARE SETUP GUIDE DOC. CONTROL # 8001467-000 REVISION B INTRODUCTION CHAPTER 1 Class 1 NanoBlock Tags The ALR-9640 RFID readers are designed to read and program Alien’s Class 1 RFID Tags. These tags comply with the MIT AutoID Center's open specification for RFID. Class I tags are “passive” devices. That is, they do not have an onboard power source. They are powered by the RF energy transmitted by the reader. They communicate with the Reader by means of “Backscatter Modulation”. Examples of Alien NanoBlock tag and antenna designs. That is, they do not actually transmit anything; they merely change their reflective characteristics in a systematic way and reflect RF energy back to the reader. An analogy to this is the way you can use a mirror to transmit information by reflecting light from the Sun. Requirements To interface with the RFID Reader you will need the following: a PC running Windows 98 or higher, with CD-ROM drive and an available RS-232 serial port standard 120 VAC power host software (Alien demo software or your own custom software) RFID Tags (AIDC Class 1 compliant) standard power cord (desired length) with grounded, 3-pronged plugs HARDWARE SETUP GUIDE DOC.

CONTROL # 8001467-000 REVISION B CHAPTER 2 READER HARDWARE INSTALLATION AND OPERATION 5. Plug power cord into power supply. Use the female end of a standard 3-pronged power cord. 6. Plug the power supply cable into the wall outlet and verify power. The LEDs will illuminate when power is on. 7. Plug in the PC (if necessary) and turn it on. 8. Launch the desired host software application. You may use Alien’s demo system software or custom software developed per the reader-host protocol for your specific application. You are now ready to bench test or demonstrate the RFID Reader system. Bench Test Procedure 1. Access an operational mode suitable for bench testing. Select a mode that will allow multiple consecutive reads of a single tag. Refer to the applicable software application user guide for specific instructions. 2. Position the reader to you can see the LEDs. You may also want to position the PC so you can view the monitor simultaneously for later tests. 3. Move a tag slowly into the antenna’s range. Begin with the tag well outside the expected range (~15-20 ft) and move it toward the antenna while observing the LEDs. 4. Verify the Lock LED illuminates when the tag is inside the read window. Lock is the green LED. 5. Verify the host receives the tag data. Refer to indications specified in applicable user guide to verify the tag was read successfully. 6. If bench test conditions are verified, proceed to installation. NOTE: To perform a hard reboot of the system, simply cycle power on the reader. HARDWARE SETUP GUIDE DOC. CONTROL # 8001467-000 REVISION B 11 READER HARDWARE INSTALLATION AND OPERATION CHAPTER 2 Installation This section provides guidance for configuring components in your RFID system. You should consider the overall design of your specific system before permanently mounting the equipment. Installation involves all the same connection steps required for bench test. However, instead of situating equipment on a tabletop, the reader and its accessories are mounted in your application environment. Requirements Before installing your RFID Reader system, you will need the following: a PC running Windows 98 or higher, with CD-ROM drive (for demo system software) and one available RS-232 serial port standard 120 VAC power for the reader and PC host software additional RS-232 cables or antenna coax cables needed to accommodate routing requirements standard grounded, three-pronged power cord of desired length mounting hardware suitable for the surface to which equipment is to be attached (e.g., wood screws, moly-bolts, brackets, etc.) Figure 9 - View of the Reader showing optional mounting kit 0500126-001 12 HARDWARE SETUP GUIDE DOC. CONTROL # 8001467-000 REVISION B CHAPTER 2 READER HARDWARE INSTALLATION AND OPERATION Hardware Installation Procedure 1. Select mounting position for ALR-9640 CAUTION: To meet FCC and Industry Canada RF Exposure guidelines the reader antennas shall be positioned so that personnel in the area for prolonged periods may safely remain at least 23 cm (9 in) in an uncontrolled environment from the antenna's surface. See FCC OET Bulletin 56 "Hazards of radio frequency and electromagnetic fields" and Bulletin 65 "Human exposure to radio frequency electromagnetic fields. The antennas shall not be co-located with other transmitting devices. Mount the ARL-9640 at the periphery of the desired read window (either overhead or at the side), so that the position of the most distant tag passing through the window is no farther from the antenna than the maximum range specified for your system design. Position the ARL-9640 at a height approximately midway between the highest and lowest expected tag position. (For example, a pallet tag may be the lowest tag position to be read, while the top-most case on a fully stacked pallet may represent your highest tag position.) Be sure power is available at the selected reader location. 2. Select location for host PC. Situate the host PC within 50 ft of the reader in a safe location away from vehicular and foot traffic. 3. Connect reader power. Push the power supply connector into the reader port. Plug the female end of the power cord into the power supply. Plug the male end of the power cord into the 120 VAC outlet. 4. Connect reader to host PC. Align the RS-232 connector with the corresponding serial port on the reader and push the connector onto the pins. Finger-tighten the screws to secure the cable to the reader. Align and connect the other end of the RS-232 with the serial port on the PC. 5. Connect power to the PC. HARDWARE SETUP GUIDE DOC. CONTROL # 8001467-000 REVISION B 13 READER HARDWARE INSTALLATION AND OPERATION CHAPTER 2 System Operation: Software Control ARL-9640 is controlled from software running on a host system that communicates with the reader using a text-based protocol. All applications use this protocol to communicate with the reader. You may operate the ARL-9640 from your own application code using this interface, use the example code provided on the CD or use the Alien RFID Gateway application - a demonstration program also included on the CD. For details, refer to either the Reader Interface Guide or the Demonstration Software Guide described briefly below. Reader Interface Guide The text-based interface mentioned above is described in detail in the Reader Interface Guide. Using this interface, the reader can be configured to read tags when queried or after one of a variety of event triggers (e.g., a rising edge on one of the I/O pins, or a timer). Tag data acquired in response to these triggers can be transmitted to the host in a number of formats (e.g., terse, text, XML or custom) and under a number of conditions (e.g., on a new tag being observed, or a tag disappearing from view). If you are a software developer, the Reader Interface Guide provides the information you will need to connect to the reader from a host computer, communicate with it, and customize its performance. Demonstration Software Guide The Demonstration Software Guide describes the installation and operation of the Alien RFID Gateway Application. The Alien RFID Gateway Application is a useful demonstration program that allows users to explore the reader’s functionality and build customizable demos with a user-friendly interface. Using the Gateway, the various operating modes of the reader can be controlled and custom interactive demos can be constructed using sounds, images, and text. 14 HARDWARE SETUP GUIDE DOC.
