If you cannot discover an HID access control unit using the Unit enrollment tool, you can troubleshoot the cause of the issue.


  1. In the Advanced Setup of HID VertX web page, make sure the Host Name is set, and that is does not have more than 15 characters.

    The Host Name must be set, and it must have less than 15 characters to be discovered.

  2. Make sure the unit is on the same network subnet as the computer where Config Tool is running.

    Discovery only works within the same broadcast domain.

  3. Make sure the unit firmware is up to date.

    For a list of supported firmware versions, see the Security Center Release Notes.
