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-411 and VS-401xlm
Vertical 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-1211 machines become 24x1, etc.) The
machines may also be operated in parallel (three VS-1211 machines become a 12x3 video component switcher).
Video signal bandwidth is 250MHz (typical), allowing the machines to be used in the most demanding
applications.
