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.
