KERI SYSTEMS 2 DOOR XTREME CONTROLLER
Product Info
The NXT-2D 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, CAT-5 cable. The NXT-2D 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 proprietary MAC addressing scheme allows for reliable hardware discovery and true one-button auto-configuration.
To expand the system’s flexibility, up to two 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 capability (4 Readers), or any reader with a st
