6.1 Rack Mounting

The Kramer VS-55 series switchers may be rack-mounted in a standard 19” (1 or 2U) EIA rack assembly,

through the BNC connectors (VS-55V), through the RCA connectors (VS-55, VS-55A), or through the 4P

connectors (VS-55YC) located on the back of the unit. The active inputs should be terminated by the

connecting source. The output signal format should match that of the input signal format, (e.g.: if

Composite video is input, then Composite video is output.) The signals supported by the various models

are video, s-video, RGB/YUV and audio signals.

8.1 Connecting and Controlling the Switchers

electronic switchers without Vertical Interval switching.

be done by using two machines of the same type, e.g., two VS-55Vs or two VS-55YCs, etc. In order

to do so, you should connect both EXT connectors to each other using a screened cable (an audio

cable will do the job well). Then connect outputs of both machines to each other using a "T"

connector. The combined output should then be connected to your acceptor. The concept of

operation is as following: the machines "sense" each other's status via the EXT connector, and when

a certain machine "senses" that the other is active, it shuts off it's own output circuitry, so in every

given instance, only one machine is actively connected to the acceptor.

interconnected "VS-55" units and the system will reset.

The VS-55 family allows remote controlling the switcher(s) using the LINK connector. Connect a

DB9 male plug with 9 wires leading from it to the remote location. A momentary touch of one of the

relevant pins (see table 1) to the common VCC pin (pin no. 8) forces the switcher to activate the

corresponding connection.
