NXT-2D - 2 Door/4 Reader Controller
Now with the ability to manage 4 readers for In/Out requirements when using Mercury Powered firmware option and NXT Readers
The NXT-2D Two Door/Four Reader Controller is built for today's IT environments. With all Ethernet functionality built directly into the controller, Keri's proprietary MAC address allows for reliable hardware discovery and true 1 button autoconfiguration. By using an existing TCP/IP network, controller cabling costs can be eliminated, or by using inexpensive unshielded CAT5 cable if building a new network they can be reduced up to 50% over traditional hard-wired access systems. The NXT-2D 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 bandwidth.
