NXT Controllers
The NXT-2D/4D Xtreme Door Controller is built for today’s IT environments. With Eth-
ernet functionality built directly into the controller. Keri’s proprietary MAC addressing
scheme allows for reliable hardware discovery and true one-button auto-configuration.
Networking between NXT-2D/4D controllers use peer-to-peer standards. The NXT-
2D/4D is designed to be extremely intelligent with little reliance on network traffic for
decision making, allowing it to be extremely thrifty with any network’s valuable band
width.
To expand the systems capabilities, up to four companion 4x4 Input/Output boards
(NXT-4x4) can be added - one to each of the controller’s RS-485 trunks (busses). Cus-
tomers can choose between Keris new line of highly secure, 4-wire NXT Series Prox-
imity Readers with reader supervision, or any reader with a standard Wiegand output or
Keri’s MS Series Proximity Readers via the NXT-RM3 Reader Interface Module.
Doors.Net, with its Client/Server architecture, is a leap forward in functionality from Keri's
acclaimed Doors
TM
software, but still has the intuitiveness and usability for which
Doors
TM
is renowned.
