Networking between NXT-4D controllers and/or its sister NXT-2D Xtreme 2 Door Controller also utilize peer to peer Ethernet standards. The NXT-4D is designed to be extremely intelligent with little reliance on network traffic for decision making allowing it to be extremely thrifty with any networks valuable bandwidth.
To expand the systems capabilities, up to four companion 4 x 4 Input/Output boards (NXT-4X4) can be added - one to each of the controllers RS-485 trunks (busses). Customers can choose between Keris new line of highly secure, 4-wire NXT Proximity Readers with reader supervision, and any reader with a standard Wiegand output or Keris MS Series Proximity Readers via the NXT-RM Reader Interface Module.
To manage the system, Doors NetXtreme software has much of the same look and feel as Keris acclaimed original DoorsTM software, but with the added functionality of Client/Server architecture.
