Overview

3. Overview
The VS-812 is a unique dual-format switcher and distribution amplifier for
composite and s-Video (Y/C) and balanced stereo audio signals. Each of the
eight inputs can be configured as either composite or s-Video (Y/C) and is
converted to produce composite and s-Video (Y/C) outputs simultaneously.
The VS-812 8x1 Composite / s-Video / Audio Switcher:
•Features high bandwidths of 370MHz (-3dB) for composite video, and
190MHz (-3dB) for s-Video (Y)
•Is a dual format 8x1 switcher with each input able to be selected as
composite or s-Video via the eight INPUT SETUP DIP-switches
•Includes built-in bidirectional format conversion: the two composite and
two s-Video (Y/C) outputs are live at all times regardless of input
configuration
•Features glitch-free transitions when the sources are genlocked
•Features vertical interval switching1
•Is controlled via the eight front panel INPUT SELECTOR buttons or
remotely via RS-232 serial commands transmitted by a touch screen
system, PC, or other serial controller front panel RS-232 (K-Router™
Windows®-based software is included)
•Has a standard 1U 19” Rack Mount Size
To achieve the best performance:
•Use only good quality connection cables2
•Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer VS-812
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).

5. Installing the VS-812 on a Rack
This section describes what to do before installing in a rack and how to rack
mount.
Before Installing in a Rack How to Rack Mount
Before installing in a rack, be sure that the environment is
within the recommended range: To rack-mount a machine:
1. Attach both ear brackets to the
machine. To do so, remove the
screws from each side of the
machine (3 on each side), and
replace those screws through the
ear brackets.
2. Place the ears of the machine
against the rack rails, and insert the
proper screws (not provided)
through each of the four holes in the
rack ears.
Note that:
•In some models, the front panel
may feature built-in rack ears
•Detachable rack ears can be
removed for desktop use
•Always mount the machine in the
rack before you attach any cables
or connect the machine to the
power
•If you are using a Kramer rack
adapter kit (for a machine that is not
19"), see the Rack Adapters user
manual for installation instructions
(you can download it at:
http://www.kramerelectronics.com)
Operating temperature range +5° to +45° C (41° to 113° F)
Operating humidity range 10 to 90% RHL, non-condensing
Storage temperature range -20° to +70° C (-4° to 158° F)
Storage humidity range 5 to 95% RHL, non-condensing
!
CAUTION
!!
When installing on a 19" rack, avoid hazards by taking
care that:
1. It is located within the recommended environmental
conditions, as the operating ambient temperature of a
closed or multi unit rack assembly may exceed the
room ambient temperature.
2. Once rack mounted, enough air will still flow around
the machine.
3. The machine is placed straight in the correct
horizontal position.
4. You do not overload the circuit(s). When connecting
the machine to the supply circuit, overloading the
circuits might have a detrimental effect on overcurrent
protection and supply wiring. Refer to the appropriate
nameplate ratings for information. For example, for
fuse replacement, see the value printed on the
product label.
5. The machine is earthed (grounded) in a reliable way
and is connected only to an electricity socket with
grounding. Pay particular attention to situations where
electricity is supplied indirectly (when the power cord
is not plugged directly into the socket in the wall), for
example, when using an extension cable or a power
strip, and that you use only the power cord that is
supplied with the machine.

To connect1Figure 2the VS-812, as illustrated in the example in , do the
following2
1. Connect up to eight composite video and stereo audio
:
3sources (for example,
composite video players) to the IN BNC connectors and terminal block4
2. Connect up to eight s-Video and stereo audio sources (for example, s-Video
players) to the IN 4-pin connectors and terminal block connectors

3. Connect the two OUT BNC connectors to up to two composite video acceptors
(for example, composite video recorders)
4. Connect the two OUT 4-pin connectors to up to two s-Video (Y/C) acceptors
(for example, s-Video recorders).
5. Connect the two OUT terminal block connectors4to up to two balanced stereo
audio acceptors (for example, balanced stereo audio amplifiers with speakers).
6. If required, you can connect a PC and/or controller to the RS-232 port.
7. Connect the power cord4,5

In addition (when using the Kramer Control software or other controller), you
can choose to connect several independent VS-812 units to a PC, as section
6.2 describes, and/or to connect a set of VS-812 units to a PC, as section 6.3
describes.
6.2 Connecting Several Independent VS-812 Units to a PC
This section describes preparing the RS-232 connectors (see section 6.2.1),
adjusting Jumpers JMP4 and JMP5 (see section 6.2.2), and setting the
DIP-switches on an independent VS-812 unit (see section 6.2.3).
6.2.1 Connecting via RS-232 Using a PC
To connect a PC to an independent1
•Connect the RS-232 9-pin D-sub rear panel port on the VS-812 unit to the
Null-modem adapter and connect the Null-modem adapter with a 9-wire
flat cable to the RS-232 9-pin D-sub port on your PC
VS-812 unit, using the Null-modem
adapter provided with the machine (recommended):
To connect a PC to an independent1VS-812 unit, without using a
Null-modem adapter:
•Connect the RS-232 9-pin D-sub port on your PC to the RS-232 9-pin
D-sub rear panel port on the VS-812 unit, as Figure 6illustrates (depending
on whether the PC has a 9-pin or 25-pin connector)

6.3.1 Preparing the RS-232 Connectors
To connect a PC to a set of VS-812 units, do not use a Null-modem adapter.
Do the following:
1. Prepare the RS-232 9-pin D-sub connector (A), by connecting PIN 4 to
PIN 6 and connecting PINS 8, 7, and 1 together.
2. Attach the RS-232 9-pin D-sub connector (A) to another RS-232 9-pin
D-sub M connector (B) by connecting PIN 5 to PIN 5, PIN 3 to PIN 2,
and PIN 2 to PIN 3.
3. Connect the RS-232 9-pin D-sub connector (A) to your PC’s RS-232
9-pin D-sub M port.
4. Attach the RS-232 9-pin D-sub M connector (B) to another RS-232 9-pin
D-sub M connector (C), by connecting PIN 5 to PIN 5, PIN 8 to PIN 3,
PIN 9 to PIN 2.
5. Connect the RS-232 9-pin D-sub M connector (B) to the RS-232 9-pin
D-sub port on the first VS-812 unit.
6. Attach the RS-232 9-pin D-sub M connector (C) to another RS-232 9-pin
D-sub M connector, if required, by connecting PIN 5 to PIN 5, PIN 8 to
PIN 3, PIN 9 to PIN 2.

6.3.2 Shorting Jumpers JMP4 and JMP5
When connecting a PC to a set of VS-812 units you need to adjust the factory
default by opening each VS-812 unit, shorting (closing) Jumpers JMP4 and
JMP5, and then closing each VS-812 unit. Figure 11 illustrates the location of
Jumpers JMP4 and JMP5:

unit (with DIP 4 OFF), which are controlled by one RS-232 port.
To connect the set of three looped VS-812 units:
1. Connect the CV OUT 1 connector and the OUT 1 Audio (CV) connector on
the first VS-812 unit to the CV video acceptor.
2. Connect the Y/C OUT 1 connector and the OUT 2 Audio (Y/C) connector on
the first VS-812 unit to the Y/C video acceptor.
3. Connect the CV OUT 1 connector on the second VS-812 unit to the CV IN 8
connector on the first VS-812 unit and connect the OUT 1 Audio (CV)
connector on the second VS-812 unit to the IN 8 Audio (CV) connector on the
first VS-812 unit.
4. Connect the Y/C OUT 1 connector on the second VS-812 unit to the Y/C IN 8
connector on the first VS-812 unit and connect the OUT 2 Audio (Y/C)
connector on the second VS-812 unit to the IN 8 Audio (Y/C) connector on the
first VS-812 unit.
5. Connect the CV OUT 1 connector on the third VS-812 unit to the CV IN 8
connector on the second VS-812 unit and connect the OUT 1 Audio (CV)
connector on the third VS-812 unit to the IN 8 Audio (CV) connector on the
second VS-812 unit.
6. Connect the Y/C OUT 1 connector on the third VS-812 unit to the Y/C IN 8
connector on the second VS-812 unit and connect the OUT 2 Audio (Y/C)
connector on the third VS-812 unit to the IN 8 Audio (Y/C) connector on the
second VS-812 unit.
You can switch any one of the 21 CV inputs to the CV video acceptor and any
one of the 21 Y/C inputs to the CV video acceptor.
