Kantech USB-485 Communication Interface

Easily bridge modern PCs with legacy door controllers to streamline access control and security monitoring. The Kantech USB-485 Communication Interface protocol converter connects a workstation's USB port to the RS-485 bus on Kantech controllers (KT-1, KT-200, KT-300, KT-400), delivering a dependable link for surveillance, monitoring and facility security management. By supporting up to 32 controllers on a single segment, the USB-485 reduces the need for additional serial hardware and simplifies cabling and system architecture.

Powered directly from the host USB port, the unit provides plug-and-play operation and extends communications up to 1,200 m (4,000 ft) over Ethernet Grade 3 unshielded twisted pair (UTP) cable—Belden 1227A recommended—making it easy to position controllers across large sites. Its USB-to-RS-485 conversion ensures consistent, low-latency communication for alarm transmission, event logging and remote monitoring. Ideal for integrators and IT teams deploying access control, perimeter security and integrated surveillance systems.
