Kantech VC-485 Multi-Function RS-232 to RS-485 Communication Interface

The Kantech VC-485 Multi-Function Communication Interface delivers reliable protocol conversion to connect a PC running EntraPass or other management software to RS-485-based KT-100/KT-200/KT-300 controllers, streamlining access control and security monitoring. As a compact RS-232 to RS-485 converter, the VC-485 supports up to 32 Kantech controllers and extends the communication bus up to 1,200 m (4,000 ft) using Ethernet Grade 3 unshielded twisted pair (Belden #1227A recommended). For even longer runs, two VC-485 units can be connected back-to-back to reach up to 5,486 m (18,000 ft), minimizing the need for additional networking hardware.

Designed for security integrators and IT teams, this multi-function communication interface uses standard UTP cabling and offers 5 VDC or 12 VDC power options for flexible installation. It improves system uptime and simplifies troubleshooting for surveillance, monitoring, and access control deployments. Ideal for retrofits and new installations where reliable RS-485 communication is critical—add the Kantech VC-485 to your next security project to enhance connectivity and scalability.
