VC-485

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.

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.
