3 Overview
The VS-4x4YCxl is a true 4x4 matrix switcher for s-Video signals and
balanced stereo audio signals. The high quality VS-4x4YCxl lets you
simultaneously route any or all of the 4 inputs to any or all of the 4 outputs.
The VS-4x4YCxl 4x4 s-Video Audio Matrix Switcher includes:
 Video bandwidth of 75MHz that ensures transparent performance
 Easy-to-connect detachable terminal block connectors for the audio signals
 Glitch-free transitions, which are produced when sources share a common
reference sync
1
 DC coupled inputs and outputs
 Audio-follow-video and breakaway options
 Storing and recalling setups
 “Take” button for precise switch control
 “Lock” button to prevent tampering with the front panel
 The ability to control via the front panel buttons, via the Infra-red remote
control transmitter, and remotely by RS-485 or RS-232 serial commands
transmitted by a touch screen system, PC, or other serial controller
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-4x4YCxl
away from moisture, excessive sunlight and dust

5.2 Controlling via RS-232 (for example, using a PC)
To connect a PC to the VS-4x4YCxl unit, using the Null-modem adapter
provided with the machine (recommended):
 Connect the RS-232 DB9 rear panel port on the Master VS-4x4YCxl unit
to the Null-modem adapter and connect the Null-modem adapter with a 9
wire flat cable to the RS-232 DB9 port on your PC

5.3 Controlling via RS-485
You can control a VS-4x4YCxl unit via an RS-485 controller, for example, a
PC (equipped with an RS-485 interface) or a Master Programmable Remote
Control system such as the Kramer RC-3000
1
.
To connect an RC-3000 to a VS-4x4YCxl unit (see Figure 5):
1. Connect the RS-485 terminal block port on the RC-3000 to the RS-485
port on the VS-4x4YCxl unit, as follows:
 Connect the “ A” (+) PIN on the RS-485 rear panel port of the
RC-3000 to the “ A” (+) PIN on the RS-485 rear panel port of the
VS-4x4YCxl unit
 Connect the “ B” (-) PIN on the RS-485 rear panel port of the
RC-3000 to the “B” (-) PIN on the RS-485 rear panel port of the
VS-4x4YCxl unit
 If shielded twisted pair cable is used, the shield may be connected to
the “ G” (Ground) PIN on one of the units (for example, on the
RC-3000)
2. Set the VS-4x4YCxl unit as MACHINE # 1, according to Table 4 (that
is, DIP 1, DIP 2, DIP 3, and DIP 4 OFF), and set the other dipswitches
on the VS-4x4YCxl unit, as follows:

5.5.1 Setting the MACHINE #
The MACHINE # determines the position of a VS-4x4YCxl unit, specifying
which VS-4x4YCxl unit is being controlled when several VS-4x4YCxl units
connect to a PC or serial controller. Set the MACHINE # on a VS-4x4YCxl
unit via DIPS 1, 2, 3 and 4, according to Table 4.
When using a stand-alone VS-4x4YCxl unit, set the MACHINE # to 1. When
connecting more than one VS-4x4YCxl unit, set the first machine (the
Master) that is closest to the PC, as MACHINE # 1

You can cascade up to 16 VS-4x4YCxl units with control from a PC or serial
controller.
To cascade up to 16 individual VS-4x4YCxl units, via RS-232 and RS-485,
do the following:
1. Connect the s-Video sources and acceptors, as well as the appropriate
stereo audio sources and acceptors, as section 5.1 describes.
2. Connect the RS-232 port on the first VS-4x4YCxl unit to the PC using
the Null-modem adapter provided with the machine (recommended), as
section 5.2 describes.
3. Connect the RS-485 terminal block port on the first VS-4x4YCxl unit to
the RS-485 port on the second VS-4x4YCxl unit and so on, connecting
all the RS-485 ports.
4. Set the dipswitches, as section 5.5 describes. In particular:
 Set the first VS-4x4YCxl unit as MACHINE # 1 and the following
15 VS-4x4YCxl units as MACHINE # 2 to MACHINE # 16,
according to Table 4.
 Set DIP 8 ON on the first and last VS-4x4YCxl units (terminating
the RS-485 line at 120). Set DIP 8 OFF on the other VS-4x4YCxl

7 Operating the VS-4x4YCxl
You can operate your VS-4x4YCxl 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
7.1 Displaying Unit Characteristics

circumstances:
 Immediately (and automatically) after switching on the power; and
 When simultaneously pressing the 3 “INPUTS” buttons
1
1, 2 and 3, for 3
seconds
The following information is displayed in the 7-segment Displays:
 The number of IN and OUT ports
2
 The firmware version number and the MACHINE #
3
Figure 11: VS-4x4YCxl Unit Characteristics
7.2 Choosing the Audio-Follow-Video or Breakaway Option
You can switch stereo audio signals in one of 2 ways, either:
 Audio-follow-video (AFV), in which all operations and status indicators
relate to both the video and the audio channels
4
; or
 Breakaway, in which video and audio channels switch independently
1 Item 4 in Table 1
2 Via the VIDEO 7-segment Display (item 7 in Table 1)
3 Via the AUDIO 7-segment Display (item 8 in Table 1)
4 Audio and video connections are the same

Operating the VS-4x4YCxl
15
7.2.1 Setting the Audio-Follow-Video Option
To set the Audio-follow-video (AFV) option:
1. Press the AFV button.
The AFV button illuminates. The audio will follow the video.
 If the audio configuration differs from the video configuration, the audio
input(s) in the Audio 7-segment Display, the AUDIO button, and the
TAKE button will blink
1
, and require reconfiguring for AFV operation
2. Press the TAKE button to confirm the modification (reconfiguring the
audio according to the video).
7.2.2 Setting the Breakaway Option
To set the Breakaway option Press either the AUDIO (for audio control only)
or the VIDEO (for video control only) button:
 If the AUDIO button illuminates, all switching operations relate to the
Audio section.
 If the VIDEO button illuminates, all switching operations relate to the
Video section
7.3 Switching OUT-IN Combinations
To switch a video/audio input to a video/audio output, do the following:
1. Press an OUT button (either 1, 2, 3, 4 or ALL).
The corresponding Audio and
2
/or Video 7-segment Displays blink.
2. Press an IN button (either 1, 2, 3, 4 or OFF).
The selected input switches to the selected output.
For example, press the ALL button and then IN button # 2 to connect input #
2 to all the outputs.
7.4 Confirming Settings
Choose to work in the AT ONCE or the CONFIRM mode, as section 7.4.1
describes. When the VS-4x4YCxl operates in the AT ONCE mode, pressing
an OUT-IN combination implements the switch immediately. In the
CONFIRM mode, the TAKE button must be pressed to authorize the switch.
1 Warning that changes are about to occur in the audio section
2 When the audio-follow-video option is active (refer to section 7.2)

KRAMER: SIMPLE CREATIVE TECHNOLOGY
Operating the VS-4x4YCxl
16
In the AT ONCE mode, you save time as execution is immediate and actions
require no user confirmation. However, no protection is offered against
changing an action in error.
In the CONFIRM mode:
 You can key-in several actions and then confirm them by pressing the
“ TAKE” button, to simultaneously activate the multiple switches
 Every action requires user confirmation, protecting against erroneous
switching
 Execution is delayed
1
until the user confirms the action
7.4.1 Toggling between the AT ONCE and CONFIRM Modes
To toggle between the AT ONCE and CONFIRM modes, do the following:
1. Press the dim TAKE button to toggle from the AT ONCE mode (in
which the TAKE button is dim) to the CONFIRM mode (in which the
TAKE button illuminates).
Actions now require user confirmation and the TAKE button
illuminates.
2. Press the illuminated TAKE button to toggle from the CONFIRM mode
back to the AT ONCE mode.
Actions no longer require user confirmation and the TAKE button no
longer illuminates.
7.4.2 Confirming a Switching Action
To confirm a switching action (in CONFIRM mode), do the following:
1. Press an OUT-IN combination.
The corresponding Audio and Video 7-segment Displays blink. The
TAKE button also blinks.
2. Press the blinking TAKE button to confirm the action.
The corresponding Audio and Video 7-segment Displays no longer
blink. The TAKE button illuminates.
To confirm several actions (in CONFIRM mode), do the following:
1. Press each OUT-IN combination in sequence.
The corresponding Audio and Video 7-segment Display blinks. The
TAKE button also blinks.
1 Failure to press the TAKE button within one minute (the Timeout) will abort the action

Operating the VS-4x4YCxl

1. Press the STO button.
The STO button blinks.

To recall an input/output configuration, do the following:

The memory recalls the stored data from that reference.
