DS-K2700 Series
Master and Distributed Access Controller
The Hikvision Master and Distributed Access Controller is composed of a master access controller and three distributed access controllers. The master access controller supports TCP/IP communication (with dual network interfaces) and RS-485 communication with the client software. It supports 4 RS-485 loops when communicating with distributor access controllers. AES encryption ensures the data security in the communication among devices. The distributed access controllers support the SPOF (Single-Point of Failure) and the redundancy processing of the card reader, so as to ensure the system stability. The master and distributed access controller is available for the industries of subways, airports, banks, and enterprises, etc..

MAIN FEATURES
Main Features of Master Access Controller
 Equipped with 2 TCP/IP interfaces and 1 RS-485 interface for the uplink communication with the client software. The TCP/IP communication and RS-485 communication can be the redundant backup for each other. 10M/100M/1000M adaptive network interfaces are supported, and up to 256 links can access.
 Equipped with 1 10M/100M TCP/IP network interface and 8 RS-485 interfaces for the downlink communication with distributed access controllers. The TCP/IP communication and RS-485 communication can be applied at the same time. The controller can adopts one kind of communication mode when another one breaks down. 8 RS-485 interfaces can form 4 RS-485 loops. Up to 16 distributed access controller can be mounted on each RS-485 loop.
