Multi-Function Communication Interface

The VC-485 is an RS-232/RS-485 protocol converter primarily used to connect a PC to a KT-200/KT-300 controller. The maximum bus length is 5 km (18,000 feet, when line repeater is used) and 1,2 km (4,000 feet) for EntraPass and WinPass when using Ethernet Grade 3, unshielded, two twisted pair cable (Belden #1227A recommended). Two VC-485’s may be connected back-to-back to be used as a line repeater in order to extend the RS-485 communication bus.
The VC-485 Communication Interface is UL listed if used with a KT-300 and is horizontally mounted on a desk using the Velcro adhesive supplied on the back of the unit.
