Replacing an NXT-MSC 2D or 4D Controller

If you need to replace an NXT-MSC (Mercury-Powered) 2-door or 4-door controller in the Doors.NET software, such as if it has been damaged, please use the following procedure to minimize the amount of system down-time:

  1. Right-click the old controller in the hardware tree (Setup >> Hardware Setup >> All) choose Disconnect.
  2. The controller will immediately go offline.
  3. Or simply down-power the old controller.
  4. In the controller properties locate the controller's MAC address (ensure that Advanced View is enabled). The MAC address begins 00-14-34.
