Good Read Led - Newland NLS-EM2096 Integration Manual

Good Read LED

The EM2096 provides a pin (LED, PIN 10) on the host interface connector that can be used by an external
driver circuit to drive an LED to indicate a Good Read status. When a good read occurs, the LED pin
produces a high level output and then the signal is back to a low level. This Good Read LED output is not
strong enough to drive an LED, so an LED driver circuit is needed.
The following LED driver circuit is provided for reference.
