Wiring Diagram with KT-200 Controllers

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 & 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.
