Page 24: Connecting And Slaving A Switcher
“Switcher Setup/Configuration” in chapter three. Connecting and Slaving a Switcher One switcher can be connected (slaved) to the System 7SC to allow for a greater number of inputs. The System 7SC serves as the master switcher, communicating with and providing video output to the projector/display. - Page 25 • SW 6 AR MX HV Computer The System 7SC master connected to a slaved switcher Connect the RS-232 ports of the two switchers. A slave adapter cable (Extron part number 26-386-01), is required for RS-232 connection. This allows the master (System 7), the slaved switcher, and the host device to be connected simultaneously.
