3. Test the tag at different locations inside the windshield. Try high and low, several inches from the vehicle’s door pillar, in
“portrait” and “landscape” orientation. Avoid embedded wires, metal coating, dark tinting, RF emitting devices. If reading
distance is too short, use a different AWID UHF card or tag.
4. Peel the plastic film off the tag. Press the tag’s adhesive flat against the inside of the windshield. This is a one-time
application. The tag will not work after it is pulled from its original position. The tag can not be moved between vehicles.
5. WS-UHF tags will not read if held in the fingers, or carried, or taped. It reads only when adhered to the windshield glass.
6.7 MT-UHF-0-0 METAL-MOUNT TAG
1. Mount the reader so that it faces the MT tag at the “sweet spot” reading location. See Figure 6 for an example at the left side.
2. The MT tag may be hand-held, or attached inside or outside the vehicle. Attachment may be permanent or temporary. Inside
the vehicle, use Velcro dots or the tag’s adhesive. Outside, use plastic screws or rivets, or adhesive, or sealant at the edges.
3. The tag must remain flat when held or attached. Do not hold or cover the tag between the two lines molded in the plastic.
4. Try vertical and horizontal orientation. Outside, vertical orientation may give best reading. Face the tag parallel to the reader.
5. Test the tag. Then finish installation by snapping the screw-hole plugs in place, for security and good appearance.
7 TESTING THE INSTALLED SYSTEM
7.1 INTRODUCTION
Install the system’s components, and apply power to all components. The LR-2000 reader and the UHF credentials may be tested in
several ways that look at isolated parts of the system, and at the integrated system. This helps to assure that the complete system is
functioning normally, and to identify a problem area, if any. (See Section 11 – Trouble-Shooting for solutions to particular problems.)
7.2 TESTING AWID’S PRODUCTS (ISOLATED)
At any time the LR-2000 reader may be disconnected from the other components of the system, and the performance of the reader
and the credentials tested by themselves.
1. Disconnect the power supply cable and the data cable from the reader. Break these circuits at the reader, not at the
power supply or at the controller panel, so that problems with the cables and junctions can be detected also.
2. Use the LR-2000KIT Test & Set-up Kit at the LR-2000 reader. Follow the instructions in Section 4, but keep the reader
installed and the cards and tags mounted normally.
3. If the test unit indicates normal reader performance using the hand-held test tag, continue testing using the UHF cards
and tags that are mounted in the vehicles.
4. If the reader is not operating, contact your source of the AWID products for a Return Material Authorization (RMA).
5. When the LR-2000KIT indicates normal operation of the reader and credentials, connect other components of the application
system one-by-one, watching for recurrence of the problem. Continue to use the LR-2000KIT as an indicator for the LR-2000
reader while the system is reconnected.
7.3 TESTING OUTPUT OF THE LR-2000 READER
The LR-2000 reader has two data outputs – Wiegand and RS-232. Wiegand is commonly used for access control systems
including automated vehicle identification. RS-232 is suited for commercial systems like truck scales and supply chain management.
There are simple techniques that show the condition of the reader’s data interfaces
1. To test the reader’s Wiegand output:
• Interface the reader’s 3 Wiegand data lines to this system’s controller, or
• Interface the reader’s 3 Wiegand data lines to a different access control system that works normally with other readers
and cards, or
• Connect a test, display or enrollment device, such as Cypress Computer Systems’ WDG-5912 Keyboard Data Wedge, or
• Connect the leads for a dual-trace oscilloscope suitable for AWID’s data output (40 microseconds pulse width,
2,000 microseconds interpulse spacing) between the reader’s Data-0 and Data-Common wires, and between Data-1
and Data-Common wires.
