EXHIBIT 8 - UHF RFID READER USER MANUAL 109.DOC PAGE 9 OF 27 Figure 4 RS 232 to RS 485 Converter connection (optional) Note: The RS 232 to RS485 converter is used to increase the distance between the reader and the host controller (typically a PC). Distances between the reader and host can be up to 1.2 km with baud rates not exceeding 100kbps. In case the host is not equipped with a 25Pin (male) secondary serial port, a 25 to 9 pin adapter must also be used to connect to the host. This connection allows for full-duplex, point-to-point communication only. The converters supplied by IPICO are optically isolated. The optically isolated converter, at the PC, must be powered from an external power supply (included). The readers do not support a RS 485 multi-drop protocol due to the amount of data throughput. Up to 4 readers can be clustered and connected via RS232 to a iP-DIMI-SA-4 controller that support a wired and wireless (optional) Ethernet connection. The iP-DIMI-SA-4 also supports 4 isolated inputs and 4 potential free N/O outputs. Readers may also interface to the outside world via RS232/Ethernet converters. This allows the readers to communicate to an iP-DIMI-SA-8 or iP-DIMI-SA-32 via hubs for intelligent local control/buffering as well as clustering/zoning of readers. Other medium and protocol converters are available on request. They include but are not limited to 802.11b Wireless LAN, Wiegand, Lonworks™, RS232-to-fiber optic etc. In the latter case, the DATA connection will be two ST-ST bulkhead connectors for multimode fibers. Please refer to IPICO support for more information regarding these options.

Operations overview The IPICO reader is designed as a read/write (RW) reader. The reader modulates READ commands to the tags in order to interrogate the tag. Depending on the application new DATA can be updated on the tag using a modulated WRITE command. Read commands will typically be 5ms in duration with a response from the tag in 300us for 64bits. A WRITE command will typically be longer and will average around 35ms. During a read event, the reader will energise a tag(s) (can be a few milliseconds i.e 7ms), followed by modulating a READ command in order to ‘get’ DATA from the tag. The reader decode the incoming signal and place a time/date stamp on it, whilst buffering the data temporarily until such time it can be send, on the communication port, to the host. If multiple DATA pages are received from the same tag before the packet is send to the host, a hit counter is increased. This hit count is included in the communication packet to the host. The RF unit does a full quadrature down conversion, and both in-phase and quadrature phase signal (I and Q) are decoded. 5. Reader overview Figure 7 UHF Integrated Reader Overview RS 232

EXHIBIT 8 - UHF RFID READER USER MANUAL 109.DOC PAGE 13 OF 27 6. Installation and Set-up Note: The following set-up is for demonstration purpose only. Installation and applications will be site dependant. 1. Install ShowTags on the controlling PC running on Windowsä 95,98 NT or 2000. It consists of a single .EXE file, which can be copied from the supplied 3.5” disk to any directory on the controlling PC and run from that directory. From time to time updates are available on the Web at http://www.IPICO.com 2. Start ShowTags. Check the serial port settings. The readers’ serial port factory setting is 9600bps, no flow control, no parity, but it will remember the last setting used. The default setting for ShowTags is the same, but the setting can be changed and saved. 3. Mount the reader on an overhead structure facing downwards (height depending on reader range and tagged object size) or vertically on a pole to such height that the horizontal centreline of the reader is inline with the tags on the objects. 4. Connect the RS 232 serial cable (default option) from the reader to a serial port on the controlling PC. Refer to Figure 4 for RS 485/422 connection. 5. Connect the Power cable from the reader to the correct power source. Remember there are two Input power supply options – Mains AC or external DC 12V – Refer to Figure 2.or Figure 3 for the correct wiring diagram. 6. Apply power to the RF unit. Refer to the technical specification regarding the Input voltage requirements for the reader. 7. Present tags into the reader beam. 8. Use ShowTags as a debugging tool to view the tag reading results and to evaluate the different reader commands. 9. The User’s application software can now be implemented. 10. Standard HP readers must be mounted in a Vertical orientation to comply with an IP 65 rating.

EXHIBIT 8 - UHF RFID READER USER MANUAL 109.DOC PAGE 14 OF 27 6.1 Quick start (Ethernet communication) Connect the Ethernet cable to J20 on the Registration Reader and proceed as follows: Note: The default factory settings are IP = 192.168.1.31 port 6543 In case the user wants to change IP/port settings of the reader, edit the file in Appendix 1 and upload the file to the reader by doing the following procedure: a. Open the Moxa SDK tool. (Download from support at www.IPICO.com) b. Do a broadcast search and select the reader that is found c. Right click on selected reader and go to “Import Configuration”

EXHIBIT 8 - UHF RFID READER USER MANUAL 109.DOC PAGE 15 OF 27 d. Click on OK and wait for the upload to finish. e. Default values in the .txt file are uploaded. Click on OK, accept the changes made and Exit the configuration tool.

EXHIBIT 8 - UHF RFID READER USER MANUAL 109.DOC PAGE 16 OF 27 8. Application notes 1. Some of the IPICO tag antenna formats are dipoles. Like dipoles, they have nulls end-on. 2. Tags should always be orientated in a plane orthogonal to the direction to the reader. 3. Reading speed depends on the tag version used. Please consult IPICO’s support team or your local dealer regarding these specifications. 4. Up to 30 tags can be read per second. This depends however on the total number of tags present in the reader beam at the same time The reading speed will reduce when more than 30 tags are present simultaneously. 5. V3 tags are recommended when a small numbers of fast moving tags are scanned (< 30 tags @ > 15 m/s). When a large numbers of tags must be scanned simultaneously, it is recommended to use V5 tags (> 120 tags @ < 3 m/s). Please consult your local dealer regarding these options. 6. Read ranges in excess of 20 m are achievable at 30 W EIRP (USA site licensed). At 4 W EIRP (USA unlicensed) the read range is about 8 m and at 500 mW, ERP (Europe) the read range is about 3 m. 7. Readers operating in small confined spaces can “jam” themselves due to unwanted reflections. Two readers operating simultaneously in close proximity from each other may also influence each other. Please consult IPICO’s support team or your local dealer regarding possible multiplexing/screening strategies. 8. The standard dipole tags must be mounted at least 18 mm away from a metallic or conductive surface, fluids and human bodies. Refer to IPICO’s range of packaged tags in order to plan an application. 9. Reflections from nearby conducting surfaces and multi-path propagation in particular can lead to nulls in the reader field. 10. Readers can be ordered with different data interfaces. Standard is RS232. Optional are Ethernet, Isolated Wiegand, Isolated RS485. Please consult your local dealer regarding such a configuration. 11. Please take note that EVI readers are fitted with 2 Linear polarised antennas and must be mounted correctly, namely horizontally. An arrow on the data plate shows the UP orientation. Note that there are 3 drainage holes on the bottom edge of the dome. Figure 8 EVI Reader Orientation Drain holes Antenna Polarisation This side UP

Surrounding structures may cause unwanted reflections or extended read capabilities. The installer needs to test and re-adjust for best performance.
