NXT-MSC Controller Troubleshooting

NXT-MSC Controller Troubleshooting


1.0 When I scan for a controller it does not Appear

  • If the controller has a DHCP address, ensure the host machine is also on the same DHCP network.
  • If there is no DHCP network the controller will configure itself with an IP address starting with 169.254.x.x
    - ensure the host is also on this 169.254.x.x IP subnet.
  • Check the controller's network status LEDs are on: D21 should be solid green, D22 should be solid red and D33 should be flashing red.

 

2.0 After Importing the controller it shows as offline

  • Verify that the PC is on the same subnet as the controller. If they are on different subnets, ensure the controller has been configured with the correct gateway IP address.

 

3.0 Not getting live events from any of the readers

  • Check the reader is showing as online (reader properties).
  • Ensure the Manufacture Model is set correctly
  • See if there is a filter assigned to the reader suppressing the events.

 

4.0 Cardholder is getting 'Access Denied - Not in File'

  • Ensure the door is added to the cardholder's access group.
  • Check if the cardholder's name is appearing in live events. If so, then check a valid access group has been selected.
  • Verify that the controller is not requiring an update (it may have been offline when card information was changed).

    Update Pending

 

5.0 When the door contact is active the reader does not go into alarm state

  • Go into the reader settings and verify that 'Beeper Control' is enabled and you have specified for the reader to go into alarm state for Door Forced, Door Held - or both alarm conditions.


6.0 The controller is generating NAK errors in live events

If you are seeing NAK events in live events then this indicates the controller requires a firmware upgrade. Click here for the controller firmware upgrade instructions.
