5.3 WIRING THE READER (FOR WIEGAND INTERFACE -- Figure 3)

1. The cable between the LR-2000 reader and the controller panel should be (see complete specifications in Section 2.3) –

• 5 conductors for data & power

• 18 gauge for 2 power wires;

22 gauge for 3 Wiegand data wires

• Stranded wire

• “Bunched” (not twisted-pair) *

• Color-coded insulation

• Overall 100% shielded

• High quality

• Maximum length – 500 feet

If the cable is twisted pair, combine negative (black wire) with one data line (green or white wire) in one twisted pair,

and combine DC power (red wire) with the other data line in a second twisted pair. This reduces crosstalk on the data lines.

2. From reader to power supply – Black wire for DC negative (first connection), and red wire for DC positive (last connection).

Each reader’s power supply must be a separate supply (see specifications in Section 2.4) that is connected to nothing else.

3. Arming circuit – For continuous RF from the reader, connect its yellow wire to the black wire at the reader permanently.

For control of the reader’s RF transmission by a vehicle sensor, connect the yellow wire to the relay contacts of the

vehicle sensor. To disarm the reader (no RF transmission from the reader), let its yellow wire float.

4. From reader to panel’s reader input port – Green wire to Data-0, white wire to Data-1, and blue wire to Data-Common.

For Data-Common, use a terminal with this name if available. If not, use this reader port’s “Common” or “Ground” terminal.

5. Drains for shields – Tie the reader’s uninsulated wire to the shields of the power and data cables. Do not ground the drain.

6. Grounds – Connect the panel’s ground to earth-ground only if instructed by the panel’s manufacturer.

The LR-2000 reader and its power supply have no ground connection. Do not connect black, blue and drain wires together.

7. Unused wires – Keep the reader’s orange wire available to connect the LR-2000KIT’s test unit during set-up and tests.

Wrap or cap the violet and brown wires separately.

8. Testing – While the cable terminations and junctions are still accessible, test the system for full function and performance.

Then seal the terminations.

5.4 AIMING THE READER

This step should be taken before the credentials are installed in or on the vehicles. From the LR-2000KIT Test & Set-up Kit,

use the test unit, and one of the hand-held test tags, and the wiring diagram in Figure 2 on page 6. The reader does not have to be

interfaced with the host system (but they may be connected together). Use the DC power module from the LR-2000KIT Test & Set-up

Kit only if the independent DC power supply is not yet connected.

1. With no vehicle present, hold the hand-held test tag approximately where the vehicles’ credentials will be located

when they are read. This is typically at about 10 feet or 15 feet from the reader, depending upon the selected tag type.

2. With the test tag held at this “sweet spot”, adjust the pan and tilt angles of the reader until the test unit indicates most robust

reading. (Occasional reads will be missed normally because of the frequency-hopping feature of the LR-2000 reader.)

3. Map the outer limits of the reader’s effective RF field by moving the tag side-to-side slowly through the field, and

along the axis from the reader’s face to the point of maximum range.
