3 Overview
The VS-42HC is a true 4x2 matrix switcher for YUV (Y, Pb/Cb, Pr/Cr) component
video and digital audio (S/PDIF) signals. The high quality VS-42HC lets you
simultaneously route any of the 4 inputs to either one or both of the outputs. The
component video and S/PDIF input and output signals are on RCA connectors, and
the S/PDIF channel 2 is also available on optical (TOSLINK1) input/output
connectors.
The VS-42HC 4x2 Home Entertainment Matrix Switcher features:
A video bandwidth of 200MHz that ensures transparent performance
An audio channel sampling rate of up to 192kHz, including multi-
channel audio (suitable for multi-channel applications, like AC3)
A built-in digital audio delay time, which corrects lip sync errors so that the
audio delay will match the video delay
DC coupled video inputs and outputs
A LOCK button to prevent tampering with the front panel
Control the VS-42HC using the front panel buttons, or remotely via:
RS-232 and RS-485 serial commands transmitted by a touch screen
system, PC, or other serial controller
The Kramer infra-red remote control transmitter
The ETHERNET
To achieve the best performance:
Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables)
Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer VS-42HC
away from moisture, excessive sunlight and dust

5 Installing the VS-42HC on a Rack
This section describes what to do before installing on a rack and how to rack
mount.
Before Installing on a Rack
Before installing on a rack, be sure that the environment is
within the recommended range:
Operating temperature range +5 to +45 Deg. Centigrade
Operating humidity range 5 to 65 % RHL, non-condensing
Storage temperature range -20 to +70 Deg. Centigrade
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 supply
connections other than direct connections to the branch
circuit (for example, the use of power strips), and that
you use only the power cord that is supplied with the
machine.
How to Rack Mount
To rack-mount the 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

6 Connecting the VS-42HC
This section describes how to connect the VS-42HC. In particular, how to:
Connect the VS-42HC rear panel (see section 6.1)
Connect the audio signals (see section 6.2)
Set the dipswitches (see section 6.3)
6.1 Connecting the VS-42HC Rear Panel
To connect the VS-42HC, as the example in Figure 3 illustrates, do the
following1:
1. Connect up to four component video sources2 (for example, four DVD
players) to the three IN RCA connectors Y, Pb/Cb and Pr/Cr (from IN 1
to IN 4) and connect the corresponding digital audio sources to the
S/PDIF3 RCA connectors (see section 6.2).
2. Connect4 the three OUT 1 RCA connectors Y, Pb/Cb and Pr/Cr to the
video acceptor (for example, a plasma display) and connect the
corresponding OUT 1 S/PDIF RCA connector (see section 6.2) to the
digital audio acceptor (for example, an AV receiver).
3. Connect the three OUT 2 RCA connectors Y, Pb/Cb and Pr/Cr to the
video acceptor (for example, a plasma display) and connect the
corresponding OUT 2 S/PDIF RCA connector and OUT 2 (TOSLINK)
connector (see section 6.2) to the digital audio acceptor (for example, the
audio connector on the digital display).
4. Set the dipswitches (see section 6.3).
5. If required, connect a PC and/or controller to the RS-232 port (see
section 7.1) and/or the RS-485 port (see section 7.2) and/or the
ETHERNET port (see section 7.3).
6. Connect the power cord5.
1 Switch OFF the power on each device before connecting it to your VS-42HC. After connecting your VS-42HC, switch on
its power and then switch on the power on each device. DO NOT push in the rear panel Flash Program “Flash Upgr.” button
(see Table 3) and DO NOT switch the ETH Flash switch. These are only used for upgrading to the latest Kramer firmware
(see section 9)
2 Although in this example four inputs are connected, you can connect less inputs
3 Or TOSLINK connector for IN 2
4 You do not need to connect both outputs
5 We recommend that you use only the power cord that is supplied with this machine
