10.14 AVOID …

• “Toll tag mentality”: If the drivers are used to high-speed tollgates with active tags, they will feel restricted by a long-range

reader using passive vehicle tags. Emphasize the desired goal of having the gate at the LR-2000 installation open, by driving

at reasonable speed in a reasonable fashion near the reader. Point out the long-life and the low cost of passive cards and tags.

• Metal in or on vehicle’s windows: Anti-glare tinting … reflective coating … metallic coating for automatic windshield wipers …

embedded wires for defrost or antenna. These metal materials can reduce or block transmission from tags to reader.

(“Lead glass” does not reduce performance.)

• Electronics in the vehicle: Anti-collision sensors and certain communications gear, while they are active, may interfere

with other RF transmission, including LR-2000’s tags and cards. However, most communications devices (cell phones,

portable radios) and GPS have no effect.

11.2 SUMMARY

The following 4 steps summarize the trouble-shooting procedure for the LR-2000 reader, from the simplest combination of products

and test tools, to the complete access control system. The detailed trouble-shooting subjects start at Section 11.3.

1. Bench-testing at your shop

: Test the reader using the instructions in Section 4 with Figure 2. Follow all steps.

Goal: To be confident that the LR-2000 works by itself stand-alone, communicating only with the test tags and the test unit..

2. Interfacing to a PC

: Connect the reader’s RS-232 output to the serial input port of a PC. Run the Microsoft Windows

HyperTerminal program. Watch for a column of data in rows of 18 hexadecimal characters. Do not mount the reader yet.

Goal: To see consistent data from the test tag’s programmed code, at the programmed repetition rate.

3. Interfacing to the system

: Connect the reader directly to the reader input port on the host system’s controller panel.

This bypasses the cable and junctions between the reader and the panel.

Goal: To see the reader transmit the tag’s code to the host system, with correct code consistently, and with access granted.

4. Connecting the complete system

: Test the system as described in Section 7, using all components of the system.

Goal: To confirm proper operation of the system in its final form.

11.3 GOOD IDEAS

 Do not “button up” the system mechanically or electrically until you have tested it thoroughly, and until you are confident

that all components are working as specified.

• Do not make final adjustments on the reader’s mounting yet. Keep the fastener’s accessible.

• Do not cut and trim cables and wires yet. Keep all terminations available for measurements and for changes.

 Identify what the system is doing wrong, or what it isn’t doing right.

• Isolate the system’s components. How does each component work alone? Decide which component is at fault.

 Keep the LR-2000KIT with you. It is absolutely necessary, and it may pay for itself in the first installation.

• The Kit tells you when the reader reads a tag. It helps also in locating tags in the vehicle, and in aiming the reader.
