So that a Morpho Sigma reader displays a message when access is granted or denied, you must configure the feedback settings on the reader.

What you should know

If the user interface described in this topic differs from what you have, ensure that you are running a compatible version of the software.


  1. Open the reader's configuration web page.
  2. Under Control Configuration, click Controller Feedback.
  3. Under Controller Feedback Settings, do the following:
    1. Set Remote Message Feedback Interface to Feedback over TTL.
    2. Set Feedback lines to One feedback line.
    3. Set Timeout to 2000ms.
  4. Configure the pulse settings as shown in the following table.
    Settings   Pulse width (ms) Pulse interval (ms)
    Granted High 100 100
    Denied None 200 200
  5. Click Save.
  6. Clear the Display User ID on Access Granted check box.
    IMPORTANT: The User ID is the entire credential as configured in Security Center, so it must never be displayed.
