4 TESTING READER AND TAGS BEFORE INSTALLATION

4.1 INTRODUCTION

Careful preparation is important for successful installation of AWID’s long-range readers and credentials. Simple bench-testing

gives the installer confidence in the performance of the reader and the credentials, before the products are taken to the site.

This testing isolates the reader and credentials from all other factors that contribute to performance of the final assembly.

4.2 ITEMS FOR BENCH TESTING

AWID’s long-range reader and credentials are tested easily using only the items listed below. It is not necessary to interface the reader

to a controller panel or reader-input module while conducting this test.

• LR-2000 reader (It does not contain an LED.) • PS-12-3.3A power module, cable with 2 clips *

• Wiring diagram, Figure 2 (below)

* A component of the LR-2000KIT Test & Set-up Kit

• HT-UHF hangtag (26-bit code), or other tag *

• SP-6820-LR test unit, cable with 3 clips *

4.3 SUPPORTING THE READER

The reader’s effective RF field, in which the long-range credentials can be detected, is maximized when there is no material in front

of the reader or immediately to the sides of the reader. See the LR-2000 Effective RF Field diagram (Figure 1 on page 4).

• Cut off the connector from the LR-2000 reader’s cable. Prepare the pigtails for the planned installation. Keep the

unused wires separated from each other.

• Hang the reader on a clear vertical surface in an open space, about 4 feet above the bench top, 4 feet from a side wall,

and 4 feet below the ceiling.

4.4 WIRING FOR QUICK TEST

• Connect the wires as shown in the wiring diagram, Figure 2 (below).

• Be sure that unused wires are touching nothing. Do not cut off unused wires yet.

• The first connection made is the reader’s black (negative power) wire. The last step is to plug in the DC power module.

4.5 HOLDING THE TAG

• Hold the test tag by the fingertips, with the hand behind the tag. Hold the tag at arm’s length, to the side of your body. Or …

• Attach the test tag to a non-metal stick. Stand to the side of the reader’s RF field, and extend the tag into the reader’s field.

• Hold the tag so that the face of the tag is approximately parallel with the reader’s face. (The reader is circular-polarized,

so the credentials may be held at any angle – up-and-down, or side-to-side, or diagonal.)

• Move the tag slowly though the effective RF field in front of the reader. Observe the edges of the zone and the point

of maximum read range. The widest part of the zone is at about half of the maximum range.
