3 Overview
The Kramer VS-121HC is a high-quality 12 x 1:2 Component Video
Switcher / Transcoder designed for home cinema applications. It features:
•Four composite video inputs on RCA connectors
•Four s-Video inputs on 4-pin connectors
•Four sets of component video inputs on RCA connectors
In particular:
•The VS-121HC supports the following video standards when
transcoding: NTSC3.58 and NTSC4.43; PAL B, D, G, H, I, M, N; and
SECAM. The VS-121HC does not support HD
•Composite and s-Video inputs are transcoded to component video, and the
component inputs are switched to two identical component video outputs
•The front panel has 12 input selector buttons, as well as a panel lock
button to prevent unintentional tampering with the front panel
•The VS-121HC has a high video bandwidth, ensuring that it remains
transparent even in the most critical applications
•The VS-121HC can operate in tandem with the VS-121HCA
The VS-121HC can be operated using the front panel buttons, or remotely via:
•RS-232 and RS-485 serial commands transmitted by PC, a touch screen
system, or other serial controller
•The ETHERNET
•The Kramer infrared remote control transmitter
The VS-121HC is housed in a 19” 1U rack-mountable enclosure, and is
powered by a 100-240 VAC universal switching power supply.
To achieve the best performance:
•Use only good quality connection cables1
•Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your
VS-121HC away from moisture, excessive sunlight, and dust
to avoid interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables)

6 Connecting the VS-121HC Switcher/Transcoder
To connect devices to the VS-121HC, as illustrated in the example in
Figure 2, perform the following1
1. Connect the following video input sources (up to 12 input devices can
be connected
:
2
One composite video source (for example, composite video player
1) to the CV IN 1 RCA connector
):
One s-Video source (for example, s-Video player 1) to the s-Video
IN 8 4-pin connector
One component video source (for example, composite video player
1) to the Y, Pb/Cb, Pr/Cr COMPONENT INPUT 12 RCA
connectors
2. Connect the output to an acceptor (1 or 2 output devices can be
connected1):
COMPONENT OUTPUT B (Y, Pb/Cb, Pr/Cr RCA connectors) to a
display3
3. Connect the power cord (not shown in Figure 2).
4. Optionally, you can connect a PC or controller to the RS-232, RS-485,
or Ethernet ports (see section 7) and/or an IR remote transmitter (see
section 7.5).
1 Switch OFF the power on each device before connecting it to your VS-121HC. After connecting your VS-121HC, switch on
its power and then switch on the power on each device
2 Not all input or output ports need to be connected
3 In this example an LCD TV display is used, but you can also connect separate outputs such as video recorders, and so on
