Use this signal to wait a controller “ACK” before granting the access.
1. If the user is recognized the MorphoAccess
TM
sends the user
identifier to the controller.
2. The MorphoAccess
TM
waits for a GND signal on LED1 or LED2. A
timeout can be defined.
3. The controller checks the user rights.
4. The controller sets LED1 to GND to authorize the access or sets
LED2 to GND to forbid the access.
This feature improves integration in an Central Security Controller (ACS).
The ACS through LED IN signals validates result of biometric matching.
LED IN mode activation
app/led IN/enabled 1
When the ACS validates the control a timeout must be specified: it defines
the time during which the MorphoAccess
TM
will wait for an
acknowledgement signal from the ACS through LED IN signals.
LED IN acknowledgement timeout in 10 ms
app/led IN/controller ack timeout 300
(0 to 3000)
If the controller has only one LED signal dedicated to “access authorized”,
this signal must be connected to LED1 input. In this case “access
forbidden” signal will be based on a timeout. "controller ack timeout" value
must be defined as short as possible in a range corresponding to
controller reply delay.
A controller with distinct outputs (one for “access forbidden”, one for
“access authorized”) will be connected to LED1 and LED2.

LED1 to GND: Access authorized.
LED2 to GND: Access refused.
