Keri Systems NXT-4D-MSC Door Reader Controller, 4-Door/8-Reader, 12 Volt DC, 650 Milliampere Input, 24 Volt DC, 1 Ampere Output, With Mercury Firmware
Also known as: NXT4DMSC, KF-NXT4DMSC, KSI-NXT4DMSC
The KERI-SYSTEMS-NXT-4D-MSC Four Door/Eight 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-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 bandwidth. The unit is equipped with a Mercury power system that brings enchanced capabilities to users of the NXT hardware platform.
