Farpointe Data - Delta3 LED Status


Overview

The Farpointe Data Delta3 readers may not correctly change LED state (red to green) during Card Access Grant cycles. This issue has been verified by Farpointe Data and a revision is being made to correct the situation for future production.

Meanwhile, to correct the behavior, wire a 10K resistor (R1) in series with the input (brown wire) as diagrammed below. By adding the resistor, it will drop the switching threshold to near 3VDC.
