Overview
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

Installing the VS-42HC on a Rack
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
(you can download it at:
http://www.kramerelectronics.com)

Operating the VS-42HC
8 Operating the VS-42HC
You can operate your VS-42HC via:
The front panel buttons
RS-232/RS-485 serial commands transmitted by a touch screen system,
PC, or other serial controller
Infra-red remote control transmitter
This section describes:
How to use the front panel buttons
How to set and adjust the audio delay time
8.1 Switching OUT-IN Combinations
There are two sets of INPUT SELECTOR buttons, the first set, TO OUTPUT
1, for switching an input (from 1 to 4) to OUT 1 and the second set, TO
OUTPUT 2, for switching an input (from 1 to 2) to OUT 2.
To switch a video/audio input to a video/audio output, press any of the
INPUT SELECTOR buttons (from 1 to 4) TO OUTPUT 1 or TO OUTPUT 2,
as required.
For example, press INPUT SELECTOR button 4 TO OUTPUT 1 and INPUT
SELECTOR button 1 TO OUTPUT 2. Now IN 4 is switched to OUT 1 and
IN 1 is switched to OUT 2. The corresponding buttons illuminate.
To turn off an output channel, press that channel’s illuminated button once
more.
8.2 Setting and Adjusting the Audio Delay Time
You can adjust the audio delay time for OUT 2 to correct lip sync errors so
that the audio delay will match the video delay. The delay time can be set and
stored separately for each input channel.
To set or adjust the audio delay, do the following:
1. Press the DELAY button on the front panel.
The DELAY button blinks
2. Press the + and – buttons to increase or decrease the delay time1
respectively.
The + and – buttons illuminate.
1 Press and hold the + or - buttons for speedy increase or decrease of the audio delay time respectively
21
Operating the VS-42HC
Decrease or increase the delay time by looking and listening, until you see
that the audio is synchronized with the video.
3. Once the delay time is set, press the DELAY button again to accept the delay
time value.
The DELAY button illuminates.
The maximum delay time is set according to the input sampling rate1, as
described in Table 10:

64 IN 3 I6 83 84 81
127 IN 4 I6 84 FF 81
For Command
For delay times exceeding 127ms, you need to send two commands (eight bytes).
The first command includes the most significant bits:
Byte 1 should be 63 (7FH)
Byte 2 should be 128 (80H) plus Most Significant bits of required delay
Byte 3 should be 128 (80H)
Byte 4 should be 128 (80H) plus machine number (from 1 up to 15)
The second command includes the less significant bits as described
previously for command 22.
Table 15 describes the hex code examples for setting the audio delay time for
delays more than 127ms:
