In a Single Controller System, the RS-485 interface option would be used if the Control Module is located at
a distance greater than 50 feet from the Host PC. Since most PC’s do not come with an RS-485 board pre-
installed, you will have to install an RS-485 board in an open slot in your PC, or purchase an RS-232 to RS-
485 converter, such as the CV-3222 sold by IMS, to use this connection interface. For wiring and connection
information please use the following table and diagram:
