5.KRAMER “VS” SERIES SWITCHERS
This section shows you all of the controls and connections of your switcher. Understanding all of the controls and connections helps you realize its full power. All the switchers described in this manual are equipped with RS-232 Connectors (for PC control) and the connector wiring is described in Figure 1. The Kramer VS-1211,VS-1201xl, VS-1011,VS-1001xlm,VS-811,VS-801xlm,VS-611,VS-601xlm,VS-411and VS-401xlmVertical Interval Switchers provide truly effortless switching between twelve, ten, eight, six or four video and balanced/unbalanced audio inputs to one output (video and audio). Switching is done during vertical interval, either of source no. 1 or of the video connected to the external sync socket. The switchers may be controlled in three ways: touch buttons, RS-232/RS-485 and contact closure via a remote socket on the back of the machines. All the units in this line can be interconnected and cascaded, (two VS-1211machines become 24x1, etc.) The machines may also be operated in parallel (three VS-1211machines become a 12x3 video component switcher). Video signal bandwidth is 250MHz (typical), allowing the machines to be used in the most demanding applications.
