Access Control System
RS-485 must be used where the distance between the controller
and the PC is greater than 30 meters or for installation of
multiple controllers. The PC will require a 311 converter to
interface between RS-232 and RS-485. The drawing below
shows a typical connection of multiple controllers with a 311-30
converter.
