The ESH400-K is a single door controller with native interfaces to four inputs, two outputs and a single Wiegand reader. The controller is optimized for interoperability with any Wiegand or Clock-and-Data reader (sold separately). The CAT-5 cable is routed to the ESH400-K which is designed to be located near the door in a secure area, and all door components are wired in a star-network like fashion directly to the controller.
