Connect the SP-6820-LR test unit, which is part of the LR Installation Kit, to the
Reader cable. Use the wiring list in the Installation Instructions. Apply power to
the reader and the test unit, using the plug-in DC power module in the Installation
Kit.
Use either a Prox-Linc WS tag that is attached firmly by its adhesive to a
rectangle of windshield glass, or a Prox-Linc MT tag for verification. Hold the tag
so that the hand does not interfere with direct line-of-sight between the tag and
the Reader.
Move the tag into the field. Observing the SR-6820-LR test unit, there is a brief
LED color change and a beep to indicate each read of the tag by the Reader.
Reads will repeat at a rate that is determined by the Reader’s firmware.
Move the tag from side to side, and at varying distances from the front of the
Reader housing, to determine the space in which the tag and Reader are active.
4.2.2 Aiming of Antenna
Antenna Pattern
MPR-2010-2.7E4-CN reader comes with a circular polarized antenna to ensure reading
tag with random orientation. Most circular polarized antenna has a horizontal to vertical
differential of up to 3 dB, this will cause the antenna pattern to deviate from a true circle.
AWID’s antenna has a horizontal to vertical differential of typically less than 0.5 dB,
making its pattern as near to a circle as possible.
