3 AWID PROPRIETARY1.0 INTRODUCTION:AWID's Sentinel-Prox LR-911 Reader is a long-range (9 to 11 feet) reader that works withpaper-thin passive windshield mounting tags or credit card size tags. This reader comes with aunique combination of long read range, small size and low power consumption. LR-911 has aninternal power DC/DC converter, allowing it to work with wide range of supply inputs withoutaffecting its performance. With a 16 V DC supply, its current consumption is less than 400 mA,making it possible to be powered directly from the supply in the access control panel, therebyeliminating the need for an external supply. LR-911 has simultaneous Wiegand and RS-232outputs, its primary applications are automated parking garage entrance control, hands-freeaccess control, asset tracking and asset management applications.1.1 General Descriptions:• Wall mount or post mount reader• Indoor or outdoor installation1.2 Special Features:• Thin passive tags with long range performance• Designed for automated operation with tags mounted on automobile’s windshield• Simultaneous Wiegand (Access Control) and RS-232 (transaction control) outputs• Permanently sealed electronics for indoor or outdoor applications• UV stabilized plastic housing1.3 Suggested Applications• Garage Gate Control• Asset Management• Item Tracking• RFID2.0 PRINCIPAL OF OPERATIONThis Radio Frequency Identification (RFID) reader uses radio frequency to identify, locate andtrack people and objects that carry the appropriate transponders. RFID readers can work innone line-of-sight situations and in darkness, bright sun light or through dirt, grime andsmudges.A typical RFID system consists of three components – an interrogator or reader, a transponderor card and a data processing panel and/or computer combination. Most RFID readers have aninternal micro-controller, transmitter, receiver and a shared transmit/receive antenna. The cardis usually passive (no internal battery) and consists of an antenna and RFID ASIC (ApplicationSpecific Integrated Circuit). During operation, the transmitter sends out an electromagneticwave to establish a zone of surveillance. When a transponder enters this zone, theelectromagnetic energy from the reader begins to energize the IC in the
4 AWID PROPRIETARYtransponder. Once the IC is energized, it goes through an initialization process and is ready toaccept further commands. Upon receiving a command to broadcast its identity, the RFID ASICbegins to broadcast its identity through a low energy back-scattering technology that selectivelyreflects or backscatters the electromagnetic energy back to the reader. The receiving circuits inthe reader senses and decodes this back-scattered signal and hence determines the identity ofthe transponder. 3.0 SPECIFICATIONS- Input voltage……………………………. +6V to + 16V DC- Input current……………………………... 1.2 to 0.40 A typical- Read range:Nominal (Line of Sight) 10 feetTransmit frequency……………………… 902-928 MHz- Receiver frequency……………………… 902-928 MHz (Amplitude Modulated)- Operating temperature range…………...-30° C to +55° C- Color……………………………………….

Simultaneous Wiegand & RS-232 (Standard) (Others are available upon request)3.1 Measuring Read DistanceThe transponder for this Reader is designed for windshield mounting. To measure the readrange between the Reader and the transponder, the transponder must be placed behind a pieceof glass of about 0.25 inches in thickness and the transponder must be flat against the glass.Grasp the transponder by the edges and hold the transponder in the same orientation asindicated in the transponder. Move the transponder toward the Reader, with the card surfaceparallel to the Reader, until confirmed data detection occurs. This indicates that the Reader hassuccessfully read the transponder. In order to read again, the card must be fully withdrawn fromthe Reader’s field of view and then approached again.NOTE: FAILURE TO FOLLOW THE INSTALLATION GUIDE MAY RESULT IN POORPERFORMANCE OR EVEN CAUSE PERMANENT DAMAGE TO THE READER,THUS VOIDS THE PRODUCT WARRANTY.4.0 PREPARATION FOR INSTALLATION4.1 Site Survey:Always conduct a site survey before starting installation, avoid any possible sources ofinterference. If the Reader is not installed properly, the performance will be degraded or moreseriously the Reader may be damaged. The following is a list of installation procedures thatshould be followed during installation: AWID PROPRIETARY
5• Do not install the Reader in an area where sources of broadband electromagnetic noisemay exist. Avoid mounting the reader facing a cellular phone tower or in close proximityto the base station of a 900 MHz wireless telephone.• Keep all the Reader wiring at least 12 inches (30 cm) away from all other wiring, whichincludes but is not limited to, AC power, computer data wiring, telephone wiring andwiring to electrical locking devices.• Do not operate the reader in close proximity to any 900 MHz wireless equipments.4.2 Preferred Reader Installation Practices• Avoid mounting reader under direct sun light. Sun light in some locations may cause thereader to be operating at temperatures well above the 55 degrees Celsius limit.• Make sure that the supply voltage of the Reader is within specification.• Use cables with over-all braid or shield.• For best results, run the cable in an individual conduit, at least 12 inches from AC power,computer data cables and cables for electrical locking devices.• Use recommended cable. Do not use any un-shielded "Twisted Pair" type cable.• Use the largest wire gauge possible (22AWG and thicker).• Use a dedicated power supply, where necessary.• Use Single Point Grounding (Earthing) for black wire of cable. No ground loops. Outershield of cable should not be grounded.4.3 Mounting PreferenceThe LR-911 has a unidirectional antenna with an antenna beam width of about 60-70 degrees.The radiation pattern is a cone shaped beam, which should be aimed to the location where thetransponders will pass. For best results, the antenna should be mounted on a post; about 6 to 7feet from pavement with the antenna angled slightly downward.With a vehicle passing through the drive lane, the center of the antenna radiation pattern shouldproject to the windshield directly in front of the passenger side.Be sure to elevate the antenna slightly to accommodate sport utility vehicles and minivans. Fig.4.3-1 is a typical mounting arrangement that should work in most single lane and multi-lanecases.4.4 General Wiring RequirementsAll the Reader wiring must be continuously shielded. AWID recommends using #22 AWG up to#18 AWG, six or seven-conductor shielded cables. Longer distances and higher currentconsumption on the power supply line may require larger gauge wires. Due to system datatermination differences, contact your panel manufacturer for the proper wire sizes to meet theirspecific requirements. AWID PROPRIETARY

When installing the Reader, it is crucialto assure that the earth ground is the best ground available. If you elect to use the AC mainpower ground, conduct a test by measuring its resistance relative to a known good ground, suchas a cold water pipe or a structural steel that is in direct contact with the ground. The resistanceshould be less than 50 ohms. If you find that the AC main power does not provide adequateearth ground, try using a solid connection to a cold water pipe.Outer shield of cable should not be grounded.For multiple Reader installations, it is critical that all Readers are connected to the samegrounding system. Using different grounding systems will create secondary current paths orground loops that can affect the performance and cause damage to the Reader.4.8 Wiring DiagramsSee Fig’s 5.2-1,2,35.0 INSTALLATION PROCEDUREVerify that all item listed in Section 5.1 of this manual are present before starting the installation.5.1 Parts ListA.

AWID PROPRIETARY5.5 FCC RF Exposure complianceCaution: to meet FCC RF Exposure compliance, operator(s) shouldnot be closer than 10.27 inches to a transmitting antenna. Antennas must be labeled indicating minimum separationdistance per FCC RF Exposure requirements . If theinformation on the label is not clearly visible, a sign with the sameinformation must be posted within 36 inches of the antenna.Radio Frequency (RF) exposureIn order for this device to comply with FCC-adopted RF exposure limits, precautions must betaken. To meet the requirements of the FCC’s Maximum Permissible Exposure (MPE)guidelines, persons should not be closer than 10.27 inches (26.1 cm) to a transmitting antenna.For installations where an operator must handle a tag or diagnostic tool closer than 9.88 inchesto the transmitting antenna, the operator should ensure that the RF antenna is not transmittingprior to positioning the tag or tool. Once the operator has positioned the tag or diagnostic tool,and moved away a minimum of 10.27 inches from the antenna, the antenna can be re-activated.For all installations labels must be placed on individual antennas, or signs must be displayed,indicating “CAUTION: A minimum separation distance of 10.27 inches must be maintainedbetween an antenna and persons for meeting FCC RF Exposure compliance. See Usersmanual for details on operation requirements.” For more information on RF Exposure, whereincidental exposure may exceed the above guideline, please refer to the FCC Office ofEngineering and Technology Bulletin 65, Supplement C, Guidelines for Human Exposure toRadio Frequency Electromagnetic Fields, available online at:http://www.fcc.gov/oet/info/documents/bulletins/ AWID PROPRIETARY6.0 WARRANTY

AWID PROPRIETARY
13When troubleshooting, try to identify the source of the problem to a unit level. “Is the problemoriginating from the panel?” Or “is the problem originating from the Reader? “ Maybe theproblem “is the power supply?”All AWID’s readers will need only a power supply and a valid card to work properly. If thereader is connected with RED (+6…16V) and BLACK (Ground), and presented with a valid card,the reader will successfully display valid data at the test computer.To check the validity of the output data in the absence of a panel, you will need to build a patchcable between the reader and a PC. Call AWID’s Technical Support for details.If a problem persists, consult the system manufacturer. If problem is the reader, consult AWID’sTechnical Assistance Department.
