NXT-4D-UL Keri Systems 4 Door NXT Controller with Enclosure - UL-294

The NXT-4D Controlleris built for today’s IT environments. By using an existing TCP/IP network, controller cabling costs can be eliminated. Or, if building a new network, they can be reduced up to 50% over traditional hard-wired access systems by using inexpensive, shielded CAT-5 cable. The NXT-4D is designed to be extremely intelligent with little reliance on network tra c for decision making, allowing it to be thrifty with any network’s valuable bandwidth. With Ethernet functionality built directly into the controller. Keri’s propriatary MAC addressing scheme allows for reliable hardware discovery and true one-button autocon guration.
