NXT - 4D 4 Door / 8 Reader TCP/IP Controller Note: Controller shown without included enclosure. • 4 Door/8 Reader Controller for Keri’s NXT product line • On-board TCP/IP connectivity – no network adapters required • Manages 4 doors with In/Out capability when using NXT Readers • Utilize existing LAN/WAN/Ethernet or pull your own dedicated CAT-5/6 Network • Embedded MAC Address for one button Auto-Configuration • Standard 4 Pin Block and RJ-45 Jack built-in for network connection • Re-assignable Inputs and Outputs • Quick Disconnect Connectors • 50,000 Cardholders, 10,000 Event Buffer • Locking Metal Enclosure (no-enclosure option) • 128 Bit Encryption • Keri offers NXT Controllers with optional Mercury Firmware to provide enhanced functionality The NXT-4D Controller is 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 traffic 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 autoconfiguration. To expand the system’s capabilities, up to four companion 4X4 Input/Output boards (NXT-4X4) can be added - one to each of the controller’s RS-485 trunks (buses). Customers can choose between Keri’s line of highly secure, 4-wire NXT Series Proximity Readers with reader supervision that also provide In/Out reading capaiblity (8 readers), or any reader with a standard Wiegand output or Keri’s MS Series Proximity Readers via the NXT-RM3 Reader Interface Module. To manage the system, Doors.NET software has much of the same look and feel as Keri’s acclaimed original DoorsTM software, but with the added functionality of a Client/Server architecture. 2305 Bering Drive San Jose, California 95131 408-435-8400 Toll Free: 800-260-5265 Fax: 408-577-1792 NXT 4D - 4 Door / 8 Reader TCP/IP Controller DATA SHEET, Page 2 of 2 Specifications: NXT-4D Installation Drawing Power Ground Size (Enclosure): 13.125” H x 10.625” W x 3.06” D (33.34 cm x 26.99 cm x 7.77 cm) Input Voltage: + 12 VDC nom.
