AWID PROPRIETARY 1.0 INTRODUCTION: AWID's Sentinel-Prox LR-911 Reader is a long-range (9 to 11 feet) reader that works with paper-thin passive windshield mounting tags or credit card size tags. This reader comes with a unique combination of long read range, small size and low power consumption. LR-911 has an internal power DC/DC converter, allowing it to work with wide range of supply inputs without affecting its performance.
AWID PROPRIETARY transponder. Once the IC is energized, it goes through an initialization process and is ready to accept further commands. Upon receiving a command to broadcast its identity, the RFID ASIC begins to broadcast its identity through a low energy back-scattering technology that selectively reflects or backscatters the electromagnetic energy back to the reader. The receiving circuits in the reader senses and decodes this back-scattered signal and hence determines the identity of the transponder.
• • • Do not install the Reader in an area where sources of broadband electromagnetic noise may exist. Avoid mounting the reader facing a cellular phone tower or in close proximity to 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, which includes but is not limited to, AC power, computer data wiring, telephone wiring and wiring to electrical locking devices.

When installing the Reader, it is crucial to assure that the earth ground is the best ground available.
1.) 2.) 3.) 4.) 5.) Installation Procedure Position the Reader (Item b on Parts List) at the desired mounting position on a mounting post or a mounting surface. Use Figure. 1 as guide. For straight mounting, drill four small holes for mounting screws, and one clearance hole for reader cable. The installer determines the size of the mounting holes and the clearance hole. For straight mounting, insert both cable slot plugs (item g on Parts List) to bottom cover.

5.4 Mounting a. Check to ensure all connections are secure. Feed all wires through the cable access hole to the rear or the side of the mounting position. b. Mount the Reader with the four #6-32 x 1” Machine screws, P/N: 0616MPP and the four #6-32 Hex Machine Screw Nuts, P/N: 06NH (Item c and d on Parts List). c. Insert the Screw hole plugs (Item d on Parts List) into the screw clearance holes to conceal the screws.

When troubleshooting, try to identify the source of the problem to a unit level. “Is the problem originating from the panel?” Or “is the problem originating from the Reader? “ Maybe the problem “is the power supply?” All AWID’s readers will need only a power supply and a valid card to work properly. If the reader 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.
